Description: NUCLEIC ACIDS, KITS, AND METHODS FOR THE DIAGNOSIS, PROGNOSIS AND TREATMENT OF GLAUCOMA AND RELATED DISORDERS FIELD OF THE INVENTION The present invention relates to the field of diagnostic and prognostic methods and kits, treatments, and compositions useful in understanding and identifying glaucoma, related intraocular pressure-disorders, and steroid sensitivity. CROSS REFERENCETO RELATED APPLICATIONS This application is a continuation-in-part of U.S. Patent Application serial no. 09/227,881, filed January 11, 1999, specifically incorporated by reference herein, which is a continuation-in-part of U.S. Patent Application serial no. 08/938,669, filed September 26, 1997, specifically incorporated by reference herein, which is a continuation-in-part of U.S. Patent Application serial no. 08/791,154, filed January 28, 1997, also specifically incorporated by reference herein. BACKGROUND OF THE INVENTION A group of debilitating eye diseases, the "Glaucomas" represent the leading cause of preventable blindness in the United States and other developed nations. In general, glaucomas are characterized by the alteration of the trabecular meshwork (TM), which consists of specialized endothelial cells and their associated connective tissue. The TM endothelial cells line the path the aqueous humor of the eye filters through during the normal, physiological flux. The cells generate and regulate the TM by producing extracellular molecules, the composition of which is thought to directly control the aqueous fluid flow. In Primary Open Angle Glaucoma ("POAG"), the most common form of glaucoma, an alteration in the TM leads to an obstruction of the normal ability of aqueous humor to leave its chamber surrounding the iris. However, the specific cells in the chamber between the iris and the cornea, in a region called the iridocorneal angle, remain "open" in that they continue to allow the egress of aqueous fluid (see, Vaughan, D. et al., In: General Ophthalmology, Appleton & Lange, Norwalk, CT, pp. 213-230 (1992); and Gray's Anatomy, 37 th Ed., Churchill Livingstone, London, pp. 1180-1190 (1989)). As a result of the alteration in the TM and the obstruction, an increased intraocular pressure ("IOP") can be observed. IOP can result in progressive visual loss and blindness if not treated appropriately and in a timely fashion. Glaucomas are estimated to affect between 0.4% and 3.3% of all adults over 40 years old (Leske, M.C. et al., Amer. J. Epidemiol. 113: 1843-1846 (1986); Bengtsson, B., Br. J. Ophthamol. 75:483-487 (1989); Strong, N.P., Ophthal. Physiol. Opt. 12:3-1 (1992)). Moreover, the prevalence of the disease rises to over 6% of those 75 years or older (Strong, N.P., Ophthal. Physiol. Opt. 12:3-1 (1992)). A link between steroid, corticosteroid, or glucocorticoid treatments and the increased IOP found in POAG disease has long been suspected. While only 5% of the normal population have high IOP increases in response to topical glucocorticoids, greater than 40-50% of similarly treated patients with POAG show a high IOP increase (16 mm Hg). In addition, an Open Angle Glaucoma may be induced by exposure to glucocorticoids. This observation has suggested that an increased or abnormal glucocorticoid response in trabecular cells of the TM may be involved in POAG (Zhan, G.L. et al., Exper. Eye Res. 54:211-218 (1992); Yun, A.J. et al., Invest. Ophthamol. Vis. Sci. 30:2012-2022 (1989); Clark, A.F., Exper. Eye Res. 55:265 (1992); Klemetti, A., Acta Ophthamol. 68:29-33 (1990); Knepper, P.A., U.S. Patent No. 4,617,299). The ability of glucocorticoids to induce a glaucoma-like condition has led to efforts to identify genes or gene products induced by the cells of the trabecular meshwork in response (Polansky, J.R. et al, In: Glaucoma Update IV, Springer- Verlag, Berlin, pp. 20-29 (1991); Polansky J.R. and einrob, R.N., In: Handbook of Experimetal Pharmacology, Vol. 69, Springer- Verlag, Berlin, pp. 461-538 (1984)). Initial efforts using short-term exposure to dexamethasone revealed only changes in specific protein synthesis. Extended exposure to relatively high levels of dexamethasone was, however, found to induce the expression of related 66 kD and 55 kD proteins that could be visualized by gel electrophoresis (Polansky, J.R. et al, In: Glaucoma Update IV, Springer- Verlag, Berlin, pp. 20-29 (1991)). The induction kinetics of these proteins as well as their dose response characteristics were similar to the kinetics that were required for steroid-induced IOP elevation in human subjects (Polansky, J.R. et al, In: Glaucoma Update TV, Springer- Verlag, Berlin, pp. 20-29 (1991)). Problems of aggregation and apparent instability or loss of protein in the purification process were obstacles in obtaining a direct protein sequence. Nguyen et al, U.S. Patent Application No: 08/649,432, filed May 17, 1996, now U.S. Patent No. 5,789,169, the entire disclosure of which is hereby incoφorated by reference as if set forth at length herein, disclosed a novel protein sequence (the TIGR, trabecular meshwork inducible glucocorticoid response protein) highly induced by glucocorticoids in the endothelial lining cells of the human trabecular meshwork. Nguyen et al. also disclosed the cDNA sequence for that protein, the protein itself, molecules that bind to it, and nucleic acid molecules that encode it, and provided improved methods and reagents for diagnosing glaucoma and related disorders, as well as for diagnosing other diseases or conditions, such as cardiovascular, immunological, or other diseases or conditions that affect the expression or activity of the protein. Because increased IOP is a readily measurable characteristic of glaucoma, the diagnosis of the disease is largely screened for by measuring intraocular pressure (tonometry) (Strong, N.P., Ophthal. Physiol Opt. 12:3-1 (1992), Greve, M. et al, Can. J. Ophthamol. 25:201-206 (1993)). Unfortunately, because glaucomatous and normal pressure ranges overlap, such methods are of limited value unless multiple readings are obtained (Hitchings, R.A., Br. J. Ophthamol. 77:326 (1993); Tuck, M.W. et al, Ophthal. Physiol. Opt. 13:221-232 (1993); Vaughan, D. et al, In: General Ophthamology, Appleton & Lange, Norwalk, CT, pp. 213-230 (1992); Vernon, S.A., Eye 7:134-137 (1993)). Patients may also have a differential sensitivity to optic nerve damage at a given IOP. For these reasons, additional methods, such as direct examination of the optic disk and determination of the extent of a patient's visual field loss are often conducted to improve the accuracy of diagnosis (Greve, M. et al, Can. J. Ophthamol. 28:201- 206 (1993)). Moreover, these techniques are of limited prognostic value. In some aspects, the present invention fulfills the need for improved diagnostic and prognostic methods. The elevation of intraocular pressure (IOP) due to topical corticosteroids (and other routes of administration) is an important clinical problem that limits the clinical use of these effective anti-inflammatory agents. If not observed in sufficient time, the IOP elevation (especially in certain individuals who show the high end of steroid-induced IOP elevations) can result in optic nerve damage and permanent visual field loss, termed "steroid glaucoma." Even patients taking inhaled, nasal, rectal, and facial steroids may be at risk. The present invention, in part, provides improved diagnostic agents, prognostic agents, therapeutic agents and methods that address this clinical problem. SUMMARY OF THE INVENTION The invention relates to nucleic acids, genes, proteins and cells that can be used in the treatment, diagnosis, prognosis, and identification of glaucoma, IOP-related disorders, or steroid sensitivity. The invention encompasses numerous agents, compositions, and methods, some of which are described by the objects and aspects of the invention detailed below. Others can be devised from the entire contents of this disclosure, and from the detailed description that follows. In one aspect, the invention relates to nucleic acids comprising non-coding regions or promoter regions associated with the TIGR (trabecular meshwork inducible glucocorticoid response) gene of mammals. These nucleic acids can be used in identifying polymorphisms in the genomes of mammals and humans that predict steroid sensitivity or a susceptibility to glaucomas or diseases related to alterations in IOP. A number of diagnostic or prognostic methods and kits can be designed from these nucleic acids. In one embodiment, the nucleic acids can be used to identify or detect a single base polymorphism in a genome. In other embodiments, two or more single base polymorphisms or multiple base polymorphisms can be identified or detected. The detection of a known polymorphism can be the basis for diagnostic and prognostic methods and kits of the invention. Various methods of detecting nucleic acids can be used in these methods and with the kits, including, but not limited to, solution hybridization, hybridization to microarrays containing immobilized nucleic acids or other immobilized nucleic acids, amplification-based methods such as PCR and the like, and an appropriate biosensor apparatus comprising a nucleic acid or nucleic acid binding reagent. In another aspect, the invention relates to specific sequences and variants or mutants from the promoter or 5' regulatory region of the human TIGR gene and nucleic acids incorporating these sequences, variants or mutants. The nucleic acids can be incoφorated into the methods and kits of the invention, or used in expression systems, vectors, and cells to produce a protein or polypeptide of interest, or used in methods to identify or detect regulatory proteins or proteins that specifically bind to promoter or regulatory regions of the TIGR gene. While many of the examples below detail work from human tissue, other animals may be used as a source of the sequences. In one embodiment of this aspect of the invention, for example, nucleic acids having the disclosed TIGRmtl 1 sequence variant, represented by the change at nucleotide 5113 in SEQ ID NO: 1, 3, or 34 from T to C, or the change in nucleotide 5117 in SEQ ID NO: 2 from T to C. The presence of sequence variant mtl 1 is linked to the high IOP response to steroid treatments and a nucleic acid incoφorating the singe base substitution can be used to identify and determine individuals at risk for developing glaucoma from undergoing a steroid treatment therapy, or a progression from an ocular hypertensive state, or those with a steroid sensitivity. And, because of the link between high IOP responses to steroids and the later development of glaucoma, nucleic acids having the TIGRmtl 1 sequence variant may also be used to identify the risk of developing glaucomas, such as POAG. The identification of changes in IOP can be done by any known means, however, the "Ar aly" criteria is preferred {see Armaly, M.F., Arch. Ophthalmol 70:492 (1963); Armaly, M.F., Arch Ophtalmol. 75:32-35 (1966); Kitazawa, Y. et al, Arch. Ophthalmol. 99:819-823 (1981); Lewis, J.M. et al, Amer. J. Ophthalmol. 106:607-612 (1988); Becker, B. et al. Amer. J .Ophthalmol 57:543 (1967), all of which are specifically incoφorated herein by reference in their entireties).

Agents of the Invention As used herein, the term "glaucoma" has its art recognized meaning, and includes both primary glaucomas, secondary glaucomas, juvenile glaucomas, congenital glaucomas, and familial glaucomas, including, without limitation, pigmentary glaucoma, high tension glaucoma and low tension glaucoma and their related diseases. The methods of the present invention are particularly relevant to the diagnosis of POAG, OAG, juvenile glaucoma, and inherited glaucomas. The methods of the present invention are also particularly relevant to the prognosis of POAG, OAG, juvenile glaucoma, and inherited glaucomas. A disease or condition is said to be related to glaucoma if it possesses or exhibits a symptom of glaucoma, for example, an increased intra-ocular pressure resulting from aqueous outflow resistance (see, Vaughan, D. et al, In: General Ophthamology, Appleton & Lange, Norwalk, CT, pp. 213-230 (1992)). The preferred agents of the present invention are discussed in detail below. The agents of the present invention are capable of being used to diagnose the presence or severity of glaucoma and its related diseases in a patient suffering from glaucoma (a "glaucomatous patient"). The agents of the present invention are also capable of being used to prognose the presence or severity of glaucoma and its related diseases in a person not yet suffering from any clinical manifestations of glaucoma. Such agents may be either naturally occurring or non-naturally occurring. As used herein, a naturally occurring molecule may be "substantially purified," if desired, such that one or more molecules that is or may be present in a naturally occurring preparation containing that molecule will have been removed or will be present at a lower concentration than that at which it would normally be found. The agents of the present invention will preferably be "biologically active" with respect to either a structural attribute, such as the capacity of a nucleic acid to hybridize to another nucleic acid molecule, or the ability of a protein to be bound by antibody (or to compete with another molecule for such binding). Alternatively, such an attribute may be catalytic, and thus involve the capacity of the agent to mediate a chemical reaction or response. As used herein, the term "TIGR protein" refers to a protein having the amino acid sequence of SEQ ID NO: 32. As used herein, the agents of the present invention comprise nucleic acid molecules, proteins, and organic molecules. As indicated above, the trabecular meshwork has been proposed to play an important role in the normal flow of the aqueous, and has been presumed to be the major site of outflow resistance in glaucomatous eyes. Human trabecular meshwork (HTM) cells are endothelial like cells which line the outflow channels by which aqueous humor exits the eye; altered synthetic function of the cells may be involved in the pathogenesis of steroid glaucoma and other types of glaucoma. Sustained steroid treatment of these cells are interesting because it showed that a major difference was observed when compared to 1-2 day glucocorticoid (GC) exposure. This difference appears relevant to the clinical onset of steroid glaucoma (1-6 weeks). Although trabecular meshwork cells had been found to induce specific proteins in response to glucocorticoids (see, Polansky, J.R., In: "Basic Aspects of Glaucoma Research III", Schattauer, New York 307-318 (1993)), efforts to purify the expressed protein were encumbered by insolubility and other problems. Nguyen, T.D. et al, (In: "Basic Aspects of Glaucoma Research III", Schattauer, New York, 331-343 (1993), herein incoφorated by reference) used a molecular cloning approach to isolate a highly induced mRNA species from glucocorticoid- induced human trabecular cells. The mRNA exhibited a time course of induction that was similar to the glucocorticoid-induced proteins. The clone was designated "II.2" (ATCC No: 97994, American Type Culture Collection, Manassas, VA). Nguyen et al, U.S. Patent Application No: 08/649,432 filed May 17, 1996, isolated a π.2 clone which encoded a novel secretory protein that is induced in cells of the trabecular meshwork upon exposure to glucocorticoids. It has been proposed that this protein may become deposited in the extracellular spaces of the trabecular meshwork and bind to the surface of the endothelial cells that line the trabecular meshwork, thus causing a decrease in aqueous flow. Quantitative dot blot analysis and PCR evaluations have shown that the mRNA exhibits a progressive induction with time whereas other known GC-inductions from other systems and found in HTM cells (metallothionein, alpha- 1 acid glycoprotein and alpha- 1 antichymotrypsin) reached maximum level at one day or earlier. Of particular interest, the induction level of this clone was very high (4-6% total cellular mRNA) with control levels undetectable without PCR method. Based on studies of 3 s methionine cell labeling, the clone has the characteristics recently discovered for the major GC-induced extracellular glycoprotein in these cells, which is a sialenated, N-glycosylated molecule with a putative inositol phosphate anchor. The induction of mRNA approached 4% of the total cellular mRNA. The mRNA increased progressively over 10 days of dexamethasone treatment. The π.2 clone is 2.0 Kb whereas the Northern blotting shows a band of 2.5 Kb. Although not including a poly A tail, the 3' end of the clone contains two consensus polyadenylation signals. A genomic clone was isolated and designated Pi TIGR clone (ATCC No: 97570, American Type Culture Collection, Rockville, Maryland). In-situ hybridization using the PjTIGR clone shows a TIGR gene and/or a sequence or sequences that specifically hybridize to the TIGR gene located at chromosome 1, q21-27, and more preferably to the ΗGR gene located at chromosome 1, q22-26, and most preferably to the TIGR gene located at chromosome 1, q24. Clone PiTIGR comprises human genomic sequences that specifically hybridize to the TIGR gene cloned into the BamϊΩ. site of vector pCYPAC (Ioannou et al, Nature Genetics, 6:84-89 (1994) herein incoφorated by reference). As used herein, the term "TIGR gene" refers to the region of DNA involved in producing a TIGR protein; it includes, without limitation, regions preceeding and following the coding region as well as intervening sequences between individual coding regions. As used herein, the term "TIGR exon" refers to any interrupted region of the ΗGR gene that serves as a template for a mature TIGR mRNA molecule. As used herein, the term "ΗGR intron" refers to a region of the TIGR gene which is non-coding and serves as a template for a TIGR mRNA molecule. Localization studies using a Stanford G3 radiation hybrid panel mapped the TIGR gene near the D1S2536 marker with a LOD score of 6.0 (Richard et al, American Journal of Human Genetics 52.5: 915-921 (1993), herein incoφorated by reference); Frazer et al, Genomics 14.3: 574-578 (1992), herein incoφorated by reference; Research Genetics, Huntsville, Alabama). Other markers in this region include: D1S210; D1S1552; D1S2536; D1S2790; SHGC-12820; and DlS2558. Sequences located upstream of the TIGR coding region are isolated and sequenced in a non-glaucomic individual. The upstream sequence is set forth in SEQ ID. No. 1 and 34. Sequence comparisons of the upstream region of a non-glaucoma individual and individuals with glaucoma identify a number of mutations in individuals with glaucoma. Some of these mutations are illustrated in Figure 2, the sequence of which can be used to identify the exact changes in the human genomic sequences from the upstream region of the TIGR gene disclosed here (SEQ ID NO: 1, 2, 3, and 34). SEQ ID NO: 3 includes the regions through the start of transcription and the start of translation, as evident from a sequence comparison to the figures. SEQ ID NO: 34 ends before the transcription start site, again as evident from a sequence comparison with the figures. Six mutations are specifically disclosed here. TIGRmtl is the result of a replacement of a cytosine with a guanine at position 4337 (SEQ ID NO: 1, SEQ ID NO: 2, and SEQ ID NO: 3). TIGRmtl is the result of a replacement of a cytosine with a thymine at position 4950 (SEQ ID NO: 1, SEQ ID NO: 2, and SEQ ID NO: 3). TIGRmt3 is the result of an addition in the following order of a guanine, a thymine, a guanine, and a thymine (GTGT) at position 4998 (SEQ ID NO: 1, SEQ ID NO: 2, and SEQ ID NO: 3). TIGRmt4 is the result of a replacement of an adenine with a guanine at position 4256 (SEQ ID NO: 1, SEQ ID NO: 2, and SEQ ID NO: 3). TIGRmtS is the result of a replacement of a guanine with an adenine at position 4262 (SEQ ID NO: 1, SEQ ID NO: 2 and SEQ ID NO: 3). TIGRmtl 1 (not pictured in Figure 2) is the result of a replacement of a thymine with a cytosine at position 5113 (SEQ ID NO: 1, 3, or 34) and at the equivalent position in SEQ ID NO: 2, at nucleotide 5117. One or more of TIGRmtl, TIGRm , TIGRmt3, TIGRmt4, TIGRmt5, and TIGTmtll can be homozygous or heterozygous. Sequence comparisons of the upstream region of a non-glaucoma individual and individuals with glaucoma identify at least one sequence variation in individuals with glaucoma. One such sequence variant is illustrated in Figure 2. TIGRsvl is the result of a replacement of an adenine with a guanine at position 4406 (SEQ ID NO: 1, SEQ ID NO: 2 and SEQ ID NO: 3). Also, the presence of TIGRmtl 1 is associated with steroid sensitivity or an increased susceptibility to developing glaucoma or IOP-related disorders during steroid or corticosteroid treatment. Molecules comprising sequences upstream of the TIGR coding region provide useful markers for polymoφhic studies. Such molecules include primers suitable for single strand conformational polymoφhic studies, examples of which are as follows: forward primer "Sk-la": 5'-TGA GGC TTC CTC TGG AAA C-3' (SEQ ID NO: 6); reverse primer "ca2": 5'-TGA AAT CAG CAC ACC AGT AG-3' (SEQ ID NO: 7); forward primer "CA2": 5'-GCA CCC ATA CCC CAA TAA TAG-3' (SEQ ID NO: 8); reverse primer "Pr+1": 5'-AGA GTT CCC CAG ATT TCA CC-3' (SEQ ID NO: 9); forward primer "Pr-1": 5'-ATC TGG GGA ACT CTT CTC AG-3' (SEQ ID NO: 10); reverse primer "Pr+2(4A2)": 5'-TAC AGT TGT TGC AGA TAC G-3' (SEQ ID NO: 11); forward primer "Pr-2(4A)": 5'-ACA ACG TAT CTG CAA CAA CTG-3' (SEQ ID NO: 12); reverse primer "Pr+3(4A)": 5'-TCA GGC TTA ACT GCA GAA CC-3' (SEQ ID NO: 13); forward primer "Pr-3(4A)": 5'-TTG GTT CTG CAG TTA AGC C-3' (SEQ ID NO: 14); reverse primer "Pr+2(4A1)": 5'-AGC AGC ACA AGG GCA ATC C-3' (SEQ ID NO: 15); reverse primer "Pr+1(4A)": 5'-ACA GGG CTA TAT TGT GGG-3' (SEQ ID NO: 16). In addition, molecules comprising sequences within TIGR exons provide useful markers for polymoφhic studies. Such molecules include primers suitable for single strand conformational polymoφhic studies, examples of which are as follows: forward primer "KS IX": 5'-CCT GAG ATG CCA GCT GTC C-3' (SEQ ID NO: 17); reverse primer "SK1XX": 5'-CTG AAG CAT TAG AAG CCA AC-3' (SEQ ID NO: 18); forward primer "KS2al": 5'-ACC TTG GAC CAG GCT GCC AG-3' (SEQ ID NO: 19); reverse primer "SK3" 5'-AGG TTT GTT CGA GTT CCA G-3' (SEQ ID NO: 20); forward primer "KS4": 5'-ACA ATT ACT GGC AAG TAT GG-3' (SEQ ID NO: 21); reverse primer "SK6A": 5'-CCT TCT CAG CCT TGC TAC C-3' (SEQ ID NO: 22); forward primer "KS5": 5'-ACA CCT CAG CAG ATG CTA CC-3' (SEQ ID NO: 23); reverse primer "SK8": 5' -ATG GAT GAC TGA CAT GGC C-3' (SEQ ID NO: 24); forward primer "KS6": 5'-AAG GAT GAA CAT GGT CAC C-3' (SEQ ID NO: 25). The locations of primers: Sk-la, ca2, CA2, Pr+1, Pr-1, Pr+2(4A2), Pr-2(4A), Pr+3(4A), Pr-3(4A), Pr-3(4A), Pr+2(4A1), and Pr+1(4A) are diagrammatically set forth in Figure 4. The location of primers: KSIX, SKIXX, Ks2al, SK3, KS4, SK6A, KS5, SK8, and KS6 are diagramatically set forth in Figure 5. The primary structure of the ΗGR coding region initiates from an ATG initiation site (SEQ ID NO:3, residues 5337-5339) and includes a 20 amino acid consensus signal sequence a second ATG (SEQ ID NO: 3, residues 5379-5381), indicating that the protein is a secretory protein. The nucleotide sequence for the TIGR coding region is depicted in Figure 7 (SEQ ID NO: 26). The protein contains an N-linked glycosylation site located in the most hydrophilic region of the molecule. The amino terminal portion of the protein is highly polarized and adopts alpha helical structure as shown by its hydropathy profile and the Garnier-Robison structure analysis. In contrast, the protein contains a 25 amino acid hydrophobic region near its carboxy terminus. This region may comprise a glucocorticoid-induced protein (GIP) anchoring sequence. The amino acid sequence of TIGR is depicted in Figure 8 (SEQ ID NO: 32). Study of cyclohexamide treatment in the absence and presence of GC suggest that the induction of TIGR may involve factors in addition to the GC receptor. The TIGR gene may be involved in the cellular stress response since it is also induced by stimulants such as H2O2, 12-O- tetradecanolyphorbol-13-acetate (TPA), and high glucose; this fact may relate to glaucoma pathogenesis and treatment. A preferred class of agents comprises TIGR nucleic acid molecules ('TIGR molecules") or fragments thereof. Such molecules may be either DNA or RNA. A second preferred class of agents ('TIGR molecules") comprises the TIGR protein, its peptide fragments, fusion proteins, and analogs. TIGR nucleic acid molecules or fragments thereof are capable of specifically hybridizing to other nucleic acid molecules under certain circumstances. As used herein, two nucleic acid molecules are said to be capable of specifically hybridizing to one another if the two molecules are capable of forming an anti-parallel, double-stranded nucleic acid structure. A nucleic acid molecule is said to be the "complement" of another nucleic acid molecule if the molecules exhibit complete complementarity. As used herein, molecules are said to exhibit "complete complementarity" when every nucleotide of one of the molecules is complementary to a nucleotide of the other. Two molecules are said to be "minimally complementary" if they can hybridize to one another with sufficient stability to permit them to remain annealed to one another under at least conventional "low-stringency" conditions. Similarly, the molecules are said to be "complementary" if they can hybridize to one another with sufficient stability to permit them to remain annealed to one another under conventional "high-stringency" conditions. Conventional stringency conditions are described by Sambrook et al., In: Molecular Cloning, A Laboratory Manual, 2nd Edition, Cold Spring Harbor Press, Cold Spring Harbor, New York (1989)), and by Haymes et al., In: Nucleic Acid Hybridization, A Practical Approach, IRL Press, Washington, DC (1985), the entirety of which is herein incoφorated by reference. Departures from complete complementarity are therefore permissible, as long as such departures do not completely preclude the capacity of the molecules to form a double-stranded structure. In order for an nucleic acid molecule to serve as a primer or probe it need only be sufficiently complementary in sequence to be able to form a stable double-stranded structure under the particular solvent and salt concentrations employed. Appropriate stringency conditions which promote DNA hybridization, for example, 6.0 x sodium chloride/sodium citrate (SSC) at about 45°C, followed by a wash of 2.0 x SSC at 50°C, are known to those skilled in the art or can be found in Current Protocols in Molecular Biology, John Wiley & Sons, N.Y. (1989), 6.3.1-6.3.6. For example, the salt concentration in the wash step can be selected from a low stringency of about 2.0 x SSC at 50°C to a high stringency of about 0.2 x SSC at 50°C. In addition, the temperature in the wash step can be increased from low stringency conditions at room temperature, about 22°C, to high stringency conditions at about 65°C. Both temperature and salt may be varied, or either the temperature or the salt concentration may be held constant while the other variable is changed. In a preferred embodiment, a nucleic acid of the present invention will specifically hybridize to one or more of the nucleic acid molecules set forth in SEQ ID NO: 1-5 or 34, or complements thereof, or fragments of about 20 to about 200 bases of either, under moderately stringent conditions, for example at about 2.0 x SSC and about 65°C. In a particularly preferred embodiment, a nucleic acid of the present invention will specifically hybridize to one or more of the nucleic acid molecules set forth in SEQ ID NO: 1-5 or 34, or complements or fragments of either under high stringency conditions. In one aspect of the present invention, a preferred marker nucleic acid molecule of the present invention has the nucleic acid sequence set forth in SEQ ID NO: 6-25 or 33, or complements thereof or fragments of either. In another aspect of the present invention, a preferred marker nucleic acid molecule of the present invention shares between about 80% to about 100% or about 90% to about 100% sequence identity with the nucleic acid sequence set forth in SEQ ID NO: 6 -25 or 33, or complement thereof or fragments of either. In a further aspect of the present invention, a preferred marker nucleic acid molecule of the present invention shares between about 95% to about 100% sequence identity with the sequence set forth in SEQ ID NO: 6-25 or 33, or complement thereof or fragments of either. In a more preferred aspect of the present invention, a preferred marker nucleic acid molecule of the present invention shares between 98% and about 100% sequence identity with the nucleic acid sequence set forth in SEQ ID NO:6-25 or 33, or complement thereof or fragments of either. Regulatory Regions and Agents that Bind to the Regions or Agents that Alter the Binding of a Molecule that Binds to the Regions Sequence comparisons of the upstream region identify a number of DNA motifs (cis elements) or regulatory regions. These DNA motifs or cis elements are shown in Figure 1. These motifs include, without limitation, glucocorticoid response motif(s), shear stress response motif(s), NFKB recognition motif(s), and API motif(s). The locations of these and other motifs, discussed below, are diagramatically set forth in Figure 1. As used herein, the term "cis elements capable of binding" refers to the ability of one or more of the described cis elements to specifically bind an agent. Such binding may be by any chemical, physical or biological interaction between the cis element and the agent, including, but not limited, to any covalent, steric, agostic, electronic and ionic interaction between the cis element and the agent. As used herein, the term "specifically binds" refers to the ability of the agent to bind to a specified cis element but not to wholly unrelated nucleic acid sequences. Regulatory region refers to the ability of a nucleic acid fragment, region or length to functionally perform a biological activity. The biological activity may be binding to the nucleic or specific DNA sequence. The biological activity may also modulate, enhance, inhibit or alter the transcription of a nearby coding region. The biological activity may be identified by a gel shift assay, in which binding to a nucleic acid fragment can be detected. Other methods of detecting the biological activity in a nucleic acid regulatory region are known in the art (see Current Protocols in Molecular Biology, for example). In an embodiment to identify or detect regulatory proteins or proteins or compounds that specifically bind to promoter or regulatory regions of the TIGR gene, a number of vector systems employing reporter genes can be useful. The promoter or 5' regulatory regions can be linked to control expression of the reporter gene so that the presence of the reporter gene indicates the transcriptional activity from the promoter or 5' regulatory region. The DNA constructs, vectors, and cells made for this aspect of the invention, and the methods employing them, can be useful in a variety of ways. For example, they can detect the presence or absence of tissue-specific factors that modulate TIGR gene expression. Modulating expression can mean increasing or decreasing transcription, increasing or decreasing translation, or otherwise effecting the amount of TIGR mRNA or protein present in a cell. They can also be used to identify compounds that affect TIGR gene expression, IOP-related disorders, or steroid sensitivity. These identified compounds can then be used to development therapeutic or diagnostic treatments, especially for glaucoma and IOP-related disorders. The types of expression systems and reporter genes that can be used or adapted for use are well known in the art. For example, vectors containing genes for a luciferase activity, an alkaline phosphatase activity, or a green fluorescent protein activity are commonly used. See Ausubel et al, Current Protocols in Molecular Biology, John Wiley & Sons, N.Y. (1989), and supplements through May 1999. Inserting a 5' regulatory region of the TIGR gene into a vector of this type puts the expression of the reporter gene under the control of the TIGR sequence. The vector or vectors can then be inserted into various cell types to examine differences in tissue specific expression, which can then lead to identification of tissue specific factors that modulate TIGR expression as well as compounds that affect the activity of the tissue specific factors. The vectors can also be used to detect compounds that affect the transcription modulating activity of a TIGR 5' regulatory region. Alternatively, the 5' regulatory region and reporter gene constructs can be used in homologous recombination techniques to produce cells. When properly inserted into the genome of a cell, the reporter gene will be under the control of the TIGR regulatory region. Homologously recombinant cells can than be used, as discussed above, to detect changes in and modulation of expression due to various treatments or in separate cells. For example, human trabecular meshwork cells (HTM) can be transiently or permanently transfected with a vector containing various 5' regulatory sequences from the TIGR gene that control expression of an alkaline phosphatase activity (AP). The expression of AP, or change in expression versus a control, indicates the presence of transcription-modulating sequences. By comparing the expression in HTM cells with the expression in other cells, such as Cos or HeLa cells, one can detect the presence of cell-specific compounds that influence transcriptional activity from the TIGR gene. Also, by treating the cells with test compounds, one can detect a compound that affects transcription. Additionally, once cell types have been characterized for the presence of expression modulating activity, further uses of the 5' regulatory regions can identify the presence of specific DNA binding by cellular components or proteins within particular cells. Assays and methods for detection DNA binding include, but are not limited to, gel shift assays and equivalent techniques known in the art. In gel shift assays, the presence of a compound that binds to a DNA is detected by observing a shift in the mobility of the DNA through an agarose, polyacrylamide, or other gel matrix. Thus, by running the DNA through the gel in the presence of one or more cellular components or cell extracts and comparing to controls, specific binding to the DNA can be detected. In a similar way, various compounds can be tested for their ability to affect binding of a cellular component to the DNA by treating the sample with one or more test compounds before running the DNA through the gel. Of course, the cells used in these assays need not be primary cultured cells or established cell lines. Any type of manipulated cell can be used, even those where deliberate changes to DNA binding proteins or transcription factors contained in the cell have been made. The TIGR gene sequences that may be used in the DNA constructs, cells, vectors, or in methods for detecting useful promoter regions, tissue or cell-specific components that bind TIGR gene sequences, or in the related methods to detect compounds affecting DNA binding or promoter activity, can be large, for example at least as big as 1.6 kb, or much smaller, on the order of about 10 to 300 bp. A preferred region is the 283 bp region from 5340 to 5044 of SEQ ID NO: 3, designated SEQ ID NO: 37, or a 227 bp region from 5044 to 5271 (end) of SED ID NO: 34, which is identified as SEQ ID NO: 38. Other preferred regions are identified in the Figures and SEQ IDs listed or are inherently disclosed by comparing the Figures and SEQ IDs. To illustrate, the TATA boxes in SEQ ID NO: 3 and 34 both start at position 5232. Particular regions from SEQ ID NO: 3 and 34 can be correlated with the identified regulatory regions in Figure 1, where the TATA box begins at 5230. Thus, additional preferred 5' regions can incoφorate one or more regulatory regions identified and discussed herein as well as the many sequence variations given in the consensus regulatory sequences listed in Figure 1. For example, SEQ ID NO: 37 can be changed at various places in the nGRE-Prl regulatory sequence, beginning at base 39 of SEQ ID NO: 37, to coincide with the consensus sequence given in Figure 1. Base 67 of SEQ ID NO: 37 can be changed from T to G, and bases 57 and 65 from C to A. These changes would not effect the basic regulatory activity of these sequences, but may affect the degree of regulatory modulation possible. Similar substitutions using any one or more of the listed regulatory regions can be made to a region from SEQ ID NO: 1-3, or 34. Also, substitutions that incoφorate one or more of the mutant sequences identified herein may also be made. For example, base 69 of SEQ ID NO: 37 can be changed from a T to a C to correlate with the TIGR.mtl 1 mutant herein. Numerous variants in the 5' regulatory regions incoφorating one or both of the consensus sequences changes and the changes from the identified TIGR mutants can be made. Bases may also be added or deleted without effecting the region's basic ability to modulate expression. The following discussion identifies some of the regulatory regions identified in the TIGR 5'region or other well known regulatory acitivities. As noted, these regions or sequences, or variants of them, can be incoφorated into the DNA constructs, vectors, cells, and methods of the invention. Any combination of them, with or without the above identified regions in SEQ ID NO: 37 and 18, or variants thereof, can be tested for the ability to confer tissue specific, or cell- type specific expression of an attached gene. As shown in Example 5, below, SEQ ID NO: 37 confers tissue specific expression of an attached reporter gene. The expression of AP activity is much higher in the HTM cells than in HeLa or Cos cells. Thus, tissue specific promoter or regulatory activity can be identified by detecting a change of expression levels from one cell type compared to another. Expression of the rat PRL gene is highly restricted to pituitary lactotroph cells and is induced by the cAMP-dependent protein kinase A pathway. At least one of the redundant pituitary specific elements (PRL-FPl 11) of the proximal rat PRL promotor is required for this protein kinase A effect (Rajnarayan et al, Molecular Endocrinology 4: 502-512 (1995), herein incoφorated by reference).

Illustrative Uses of the Nucleic Acids of the Invention Where one or more of the agents is a nucleic acid molecule, such nucleic acid molecule may be sense, antisense or triplex oligonucleotides corresponding to any part of the TIGR promoter, TIGR cDNA, ΗGR intron, TIGR exon or TIGR gene. In some embodiments these nucleic acids may be about 20 bases in length, as for example, SEQ. ID NO: 6-25 or 33. In some circmstances, the nucleic acids may be only about 8 bases in length. Short nucleic acids may be particularly useful in hybridization to immobilized nucleic acids in order to determine the presence of specific sequences, such as by the known methods of sequencing by hybridization. The TIGR promoter, or fragment thereof, of the present invention may be cloned into a suitable vector and utilized to promote the expression of a marker gene (e.g. firefly luciferase (de Wet, Mol. Cell Biol 7: 725-737 (1987), herein incoφorated by reference) or GUS (Jefferson et al, EMBO J. 6: 3901-3907 (1987), herein incoφorated by reference)). In another embodiment of the present invention, a ΗGR promoter may be cloned into a suitable vector and utilized to promote the expression of a TIGR gene in a suitable eukaryotic or prokaryotic host cell (e.g. human trabecular cell, Chinese hamster cell, E. coli). In another embodiment of the present invention, a TIGR promoter may be cloned into a suitable vector and utilized to promote the expression of a homologous or heterologous gene in a suitable eukaryotic or prokaryotic host cells (e.g. human trabecular cell lines, Chinese hamster cells, E. coli). Similarly, the TIGR promoter, regions of the TIGR 5' regulatory region from about 10 bp to about 1.6 kb, or regions of the TIGR 5' regulatory region that confer tissue specific expression can be used in DNA constructs, vectors, and cells to express an operably linked gene. For example, these TIGR sequences can control expression of a linked gene in a vector used for producing transgenic animals. In this way, cells or animals can be produced that express a gene in a tissue specific manner. One embodiment involves a gene therapy approach to treating glaucoma or IOP-disorder, where a transgene having the TIGR 5 'regulatory sequence is used to direct expression of a therapeutic gene into the trabecular meshwork or the cells of the trabecular meshwork. Experimental animal models can also be produced using the transgenic technology. These animal models, or cells from them or comprising these TIGR sequences, can be used in methods to screen for compounds that modulate expression of TIGR, and especially compounds that affect the steroid regulation of TIGR expression. These methods will produce therapeutic or diagnostic agents, which agents are specifically included in the invention. Thus, transgenic animals having an introduced DNA that comprises at least a portion of the TIGR 5' regulatory region are specifically included in this invention. Preferred embodiments have 5' regulatory sequences of SEQ ED NO: 37 or 38, or variant thereof, or a region of SEQ ID NO: 3 or 34, especially those that confer tissue specific expression. One skilled in the art is familiar with the production of transgenic construct, vectors, and animals (See, Ausubel et al, Current Protocols in Molecular Biology). In addition, as noted above, the 5' regulatory regions can be used to screen and identify DNA binding proteins. The specific binding of proteins or cellular components to the 5' regulatory regions can be detected, see Example 5. Screening methods for compounds that modulate the binding can also be produced using the 5 'regulatory regions of the invention, or vectors or cells comprising those regions. DNA binding proteins that increase or decrease expression can be identified. For example, cells that do not show native expression of TIGR, such as HeLa cells, may possess proteins or cellular components that inhibit expression of TIGR. While cells like TM cells may possess DNA binding proteins or cellular components that allow expression of TIGR or increase the level of TIGR expression in response to other agents, such as steroids or dexamethasone. Thus, the invention encompasses a number of methods to detect and identify proteins or cellular components that modulate expression of TIGR, or the expression of a gene under the control of the TIGR 5' regulatory region. Also, methods to detect compounds that effect that modulation are similarly encompassed, as well as therapeutic and diagnostic agents that are identified from those methods. Practitioners are familiar with the standard resource materials which describe specific conditions and procedures for the construction, manipulation and isolation of macromolecules (e.g., DNA molecules, plasmids, etc.), generation of recombinant organisms and the screening and isolating of clones, (see for example, Sambrook et al, In Molecular Cloning: A Laboratory Manual, Cold Spring Harbor Press (1989), herein incoφorated by reference in its entirety; Old and Primrose, In Principles of Gene Manipulation: An Introduction To Genetic Engineering, Blackwell (1994), herein incoφorated by reference).

For such puφose, the oligonucleotides must be capable of specifically hybridizing to a nucleic acid molecule genetically or physically linked to the TIGR gene. As used herein, the term "linked" refers to genetically, physically or operably linked. As used herein, two nucleic acid molecules are said to be capable of specifically hybridizing to one another if the two molecules are capable of forming an anti-parallel, double- stranded nucleic acid structure, whereas they are unable to form a double-stranded structure when incubated with a non-TIGR nucleic acid molecule. A nucleic acid molecule is said to be the "complement" of another nucleic acid molecule if they exhibit complete complementarity. As used herein, molecules are said to exhibit "complete complementarity" when every nucleotide of one of the molecules is complementary to a nucleotide of the other. Two molecules are said to be "minimally complementary" if they can hybridize to one another with sufficient stability to permit them to remain annealed to one another under at least conventional "low-stringency" conditions. Similarly, the molecules are said to be "complementary" if they can hybridize to one another with sufficient stability to permit them to remain annealed to one another under conventional "high-stringency" conditions. Conventional stringency conditions are described by Sambrook, J., et al, (In: Molecular Cloning, a Laboratory Manual, 2nd Edition, Cold Spring Harbor Press, Cold Spring Harbor, New York (1989)), and by Haymes, B.D., et al. (In: Nucleic Acid Hybridization, A Practical Approach, IRL Press, Washington, DC (1985)), both herein incoφorated by reference). Departures from complete complementarity are therefore permissible, as long as such departures do not completely preclude the capacity of the molecules to form a double-stranded structure. Thus, in order for an oligonucleotide to serve as a primer it need only be sufficiently complementary in sequence to be able to form a stable double-stranded structure under the particular solvent and salt concentrations employed. Apart from their diagnostic or prognostic uses, such oligonucleotides may be employed to obtain other TIGR nucleic acid molecules. Such molecules include the TIGR-encoding nucleic acid molecule of non-human animals (particularly, cats, monkeys, rodents and dogs), fragments thereof, as well as their promoters and flanking sequences. Such molecules can be readily obtained by using the above-described primers to screen cDNA or genomic libraries obtained from non-human species.

Uses of the Molecules of the Invention in the Diagnosis and Prognosis of Glaucoma and Related Diseases A particularly desired use of the present invention relates to the diagnosis of glaucoma, POAG, pigmentary glaucoma, high tension glaucoma and low tension glaucoma and their related diseases. Another particularly desired use of the present invention relates to the prognosis of glaucoma, POAG, pigmentary glaucoma, high tension glaucoma and low tension glaucoma and their related diseases. As used herein the term "glaucoma" includes both primary glaucomas, secondary glaucomas, juvenile glaucomas, congenital glaucomas, and familial glaucomas, including, without limitation, pigmentary glaucoma, high tension glaucoma and low tension glaucoma and their related diseases. As indicated above, methods for diagnosing or prognosing glaucoma suffer from inaccuracy, or require multiple examinations. The molecules of the present invention may be used to define superior assays for glaucoma. Quite apart from such usage, the molecules of the present invention may be used to diagnosis or predict an individual's sensitivity to elevated intraocular pressure upon administration of steroids such as glucocorticoids or corticosteroids, or anti-inflammatory steroids). Dexamethasone, cortisol and prednisolone are preferred steroids for this puφose. Medical conditions such as inflammatory and allergic disorders, as well as organ transplantation recipients, benefit from treatment with glucocorticoids. Certain individuals exhibit an increased IOP response to such steroids (i.e., "steroid sensitivity"), which is manifested by an undesired increase in intraocular pressure. The present invention may be employed to diagnosis or predict such sensitivity, as well as glaucoma and related diseases. In a first embodiment, the TIGR molecules of the present invention are used to determine whether an individual has a mutation affecting the level (i.e., the concentration of TIGR mRNA or protein in a sample, etc.) or pattern (i.e., the kinetics of expression, rate of decomposition, stability profile, etc.) of the TIGR expression (collectively, the "TIGR response" of a cell or bodily fluid) (for example, a mutation in the TIGR gene, or in a regulatory region(s) or other gene(s) that control or affect the expression of ΗGR), and being predictive of individuals who would be predisposed to glaucoma (prognosis), related diseases, or steroid sensitivity. As used herein, the TIGR response manifested by a cell or bodily fluid is said to be "altered" if it differs from the TIGR response of cells or of bodily fluids of normal individuals. Such alteration may be manifested by either abnormally increased or abnormally diminished TIGR response. To determine whether a TIGR response is altered, the TIGR response manifested by the cell or bodily fluid of the patient is compared with that of a similar cell sample (or bodily fluid sample) of normal individuals. As will be appreciated, it is not necessary to re-determine the TIGR response of the cell sample (or bodily fluid sample) of normal individuals each time such a comparison is made; rather, the TIGR response of a particular individual may be compared with previously obtained values of normal individuals. In one sub-embodiment, such an analysis is conducted by determining the presence and/or identity of polymoφhism(s) in the TIGR gene or its flanking regions which are associated with glaucoma, or a predisposition (prognosis) to glaucoma, related diseases, or steroid sensitivity. As used herein, the term "TIGR flanking regions" refers to those regions which are located either upstream or downstream of the TIGR coding region.

and a sequence corresponding to an upstream motif or cis element capable of binding NFKB as set forth in Figure 1 at residues 5166-5175 (or a sub-sequence thereof) may be employed as a marker nucleic acid molecule to identify such polymoφhism(s). Alternatively, such polymoφhisms can be detected through the use of a marker nucleic acid molecule or a marker protein that is genetically linked to (i.e., a polynucleotide that co- segregates with) such polymoφhism(s). As stated above, the ΗGR gene and/or a sequence or sequences that specifically hybridize to the TIGR gene have been mapped to chromosome lq, 21- 32, and more preferably to the TIGR gene located at chromosome 1, q21-27, and more preferably to the TIGR gene located at chromosome 1, q22-26, and most preferably to the TIGR gene located at chromosome 1, q24. In a preferred aspect of this embodiment, such marker nucleic acid molecules will have the nucleotide sequence of a polynucleotide that is closely genetically linked to such polymoφhism(s) (e.g., markers located at chromosome 1, q 19-25 (and more preferably chromosome 1, q23-25, and most preferably chromosome 1, q24. Localization studies using a Stanford G3 radiation hybrid panel mapped the TIGR gene with the D1S2536 marker nucleic acid molecules at the D1S2536 locus with a LOD score of 6.0. Other marker nucleic acid molecules in this region include: D1S210; D1S1552; D1S2536; D1S2790; SHGC-12820; and D1S2558. Other polynucleotide markers that map to such locations are known and can be employed to identify such polymoφhism(s). The genomes of animals and plants naturally undergo spontaneous mutation in the course of their continuing evolution (Gusella, J.F., Ann. Rev. Biochem. 55:831-854 (1986)). A "polymoφhism" in the TIGR gene or its flanking regions is a variation or difference in the sequence of the TIGR gene or its flanking regions that arises in some of the members of a species. The variant sequence and the "original" sequence co-exist in the species' population. In some instances, such co-existence is in stable or quasi-stable equilibrium. A polymoφhism is thus said to be "allelic," in that, due to the existence of the polymoφhism, some members of a species may have the original sequence (i.e. the original "allele") whereas other members may have the variant sequence (i.e. the variant "allele"). In the simplest case, only one variant sequence may exist, and the polymoφhism is thus said to be di- allelic. In other cases, the species' population may contain multiple alleles, and the polymoφhism is termed tri-allelic, etc. A single gene may have multiple different unrelated polymoφhisms. For example, it may have a di-allelic polymoφhism at one site, and a multi- allelic polymoφhism at another site. The variation that defines the polymoφhism may range from a single nucleotide variation to the insertion or deletion of extended regions within a gene. In some cases, the DNA sequence variations are in regions of the genome that are characterized by short tandem repeats (STRs) that include tandem di- or tri-nucleotide repeated motifs of nucleotides. Polymoφhisms characterized by such tandem repeats are referred to as "variable number tandem repeat" ("VNTR") polymoφhisms. VNTRs have been used in identity and paternity analysis (Weber, J.L., U.S. Patent 5,075,217; Armour, J.A.L. et al, FEBS Lett. 507:113-115 (1992); Jones, L. et al, Eur. J. Haematol. 59:144-147 (1987); Horn, G.T. et al, PCT Application WO91/14003; Jeffreys, A.J., European Patent Application 370,719; Jeffreys, A.J., U.S. Patent 5,175,082); Jeffreys. A.J. et al, Amer. J. Hum. Genet. 39:11-24 (1986); Jeffreys. A.J. et al, Nature 316:16- 79 (1985); Gray, LC. et al, Proc. R. Acad. Soc. Lond. 243:241-253 (1991); Moore, S.S. et al, Genomics 0:654-660 (1991); Jeffreys, A.J. et al, Anim. Genet. 8:1-15 (1987); Hillel, J. et al, Anim. Genet. 20:145-155 (1989); Hillel, J. et al, Genet. 724:783-789 (1990)). In an alternative embodiment, such polymoφhisms can be detected through the use of a marker nucleic acid molecule that is physically linked to such polymoφhism(s). For this puφose, marker nucleic acid molecules comprising a nucleotide sequence of a polynucleotide located within 1 mb of the polymoφhism(s), and more preferably within 100 kb of the polymoφhism(s), and most preferably within 10 kb of the polymoφhism(s) can be employed. Examples of such marker nucleic acids are set out in SEQ ID NO: 1, SEQ ID NO: 2, SEQ ID NO: 3, SEQ ID NO: 4, SEQ ID NO: 5, SEQ ID NO: 6, SEQ ID NO: 7, SEQ ID NO: 8, SEQ ID NO: 9, SEQ ID NO: 10, SEQ ID NO: 11, SEQ ED NO: 12, SEQ ED NO: 13, SEQ ED NO: 14, SEQ ED NO: 15, SEQ ED NO: 16, SEQ ED NO: 17, SEQ ED NO: 18, SEQ ID NO: 19, SEQ ID NO: 20, SEQ ED NO: 21, SEQ ID NO: 22, SEQ ID NO: 23, SEQ ED NO: 24, SEQ ID NO: 25. In another embodiment a marker nucleic acid will be used that is capable of specifically detecting TIGRmtl, TIGRmt2, TIGRmt3, TIGRmt4, TIGRmt5, TIGRmtl 1, TIGRsvl, or a combination of these mutations. Methods to detect base(s) substitutions, base(s) deletions and base(s) additions are known in the art (i.e. methods to genotype an individual). For example, "Genetic Bit Analysis ("GBA") method is disclosed by Goelet, P. et al, WO 92/15712, herein incoφorated by reference, may be used for detecting the single nucleotide polymoφhisms of the present invention. GBA is a method of polymoφhic site interrogation in which the nucleotide sequence information surrounding the site of variation in a target DNA sequence is used to design an oligonucleotide primer that is complementary to the region immediately adjacent to, but not including, the variable nucleotide in the target DNA. The target DNA template is selected from the biological sample and hybridized to the interrogating primer. This primer is extended by a single labeled dideoxynucleotide using DNA polymerase in the presence of two, and preferably all four chain terminating nucleoside triphosphate precursors. Cohen, D. et al, (PCT Application WO91/02087) describes a related method of genotyping. Other primer-guided nucleotide incoφoration procedures for assaying polymoφhic sites in DNA have been described (Komher, J. S. et al, Nucl. Acids. Res. 17:1119-11 '84 (1989), herein incoφorated by reference; Sokolov, B. P., Nucl. Acids Res. 78:3671 (1990), herein incoφorated by reference; Syvanen, A.-C, et al, Genomics 8:684 - 692 (1990), herein incoφorated by reference; Kuppuswamy, M.N. et al, Proc. Natl. Acad. Sci. (U.S.A.) 88:1143-1147 (1991), herein incoφorated by reference; Prezant, T.R. et al, Hum. Mutat. 7: 159-164 (1992), herein incoφorated by reference; Ugozzoli, L. et al, GATA 9:107-112 (1992), herein incoφorated by reference; Nyren, P. et al, Anal. Biochem. 208:171-175 (1993), herein incoφorated by reference). The detection of polymoφhic sites in a sample of DNA may be facilitated through the use of nucleic acid amplification methods. Such methods specifically increase the concentration of polynucleotides that span the polymoφhic site, or include that site and sequences located either distal or proximal to it. Such amplified molecules can be readily detected by gel electrophoresis or other means. Another preferred method of achieving such amplification employs the polymerase chain reaction ("PCR") (Mullis, K. et al, Cold Spring Harbor Symp. Quant. Biol. 57:263-273 (1986); Erlich H. et al, European Patent Appln. 50,424; European Patent Appln. 84,796, European Patent Application 258,017, European Patent Appln. 237,362; Mullis, K, European Patent Appln. 201,184; Mullis K. et al, U.S. Patent No. 4,683,202; Erlich, H., U.S. Patent No. 4,582,788; and Saiki, R. et al, U.S. Patent No. 4,683,194), using primer pairs that are capable of hybridizing to the proximal sequences that define a polymoφhism in its double-stranded form. In lieu of PCR, alternative methods, such as the "Ligase Chain Reaction" ("LCR") may be used (Barany, F., Proc. Natl. Acad. Sci. (U.S.A.) 88:189-193 (1991). LCR uses two pairs of oligonucleotide probes to exponentially amplify a specific target. The sequences of each pair of oligonucleotides is selected to permit the pair to hybridize to abutting sequences of the same strand of the target. Such hybridization forms a substrate for a template-dependent ligase. As with PCR, the resulting products thus serve as a template in subsequent cycles and an exponential amplification of the desired sequence is obtained. LCR can be performed with oligonucleotides having the proximal and distal sequences of the same strand of a polymoφhic site. In one embodiment, either oligonucleotide will be designed to include the actual polymoφhic site of the polymoφhism. In such an embodiment, the reaction conditions are selected such that the oligonucleotides can be ligated together only if the target molecule either contains or lacks the specific nucleotide that is complementary to the polymoφhic site present on the oligonucleotide. Alternatively, the oligonucleotides may be selected such that they do not include the polymoφhic site (see, Segev, D., PCT Application WO 90/01069). The "Oligonucleotide Ligation Assay" ("OLA") may alternatively be employed (Landegren, U. et al, Science 247:1077-1080 (1988)). The OLA protocol uses two oligonucleotides which are designed to be capable of hybridizing to abutting sequences of a single strand of a target. OLA, like LCR, is particularly suited for the detection of point mutations. Unlike LCR, however, OLA results in "linear" rather than exponential amplification of the target sequence. Nickerson, D.A. et al., have described a nucleic acid detection assay that combines attributes of PCR and OLA (Nickerson, D.A. et αl, Proc. Nαtl. Acαd. Sci. (U.S.A.) 87:8923-8927 (1990). In this method, PCR is used to achieve the exponential amplification of target DNA, which is then detected using OLA. In addition to requiring multiple, and separate, processing steps, one problem associated with such combinations is that they inherit all of the problems associated with PCR and OLA. Schemes based on ligation of two (or more) oligonucleotides in the presence of nucleic acid having the sequence of the resulting "di-oligonucleotide", thereby amplifying the di- oligonucleotide, are also known (Wu, D.Y. et αl, Genomics 4:560 (1989)), and may be readily adapted to the puφoses of the present invention. Other known nucleic acid amplification procedures, such as allele-specific oligomers, branched DNA technology, transcription-based amplification systems, or isothermal amplification methods may also be used to amplify and analyze such polymoφhisms (Malek, L.T. et αl, U.S. Patent 5,130,238; Davey, C. et αl., European Patent Application 329,822; Schuster et αl, U.S. Patent 5,169,766; Miller, H.I. et αl, PCT appln. WO 89/06700; Kwoh, D. et αl, Proc. Nαtl. Acαd. Sci. (USA.) 86: 1173 (1989); Gingeras, T.R. et αl, PCT application WO 88/10315; Walker, G.T. et αl, Proc. Nαtl. Acαd. Sci. (U.S.A.) 89:392-396 (1992)). All the foregoing nucleic acid amplification methods could be used to predict or diagnose glaucoma. The identification of a polymoφhism in the TIGR gene, or flanking sequences up to about 5,000 base from either end of the coding region, can be determined in a variety of ways. By correlating the presence or absence of glaucoma in an individual with the presence or absence of a polymoφhism in the TIGR gene or its flanking regions, it is possible to diagnose the predisposition (prognosis) of an asymptomatic patient to glaucoma, related diseases, or steroid sensitivity. If a polymoφhism creates or destroys a restriction endonuclease cleavage site, or if it results in the loss or insertion of DNA (e.g., a VNTR polymoφhism), it will alter the size or profile of the DNA fragments that are generated by digestion with that restriction endonuclease. As such, individuals that possess a variant sequence can be distinguished from those having the original sequence by restriction fragment analysis. Polymoφhisms that can be identified in this manner are termed "restriction fragment length polymoφhisms" ("RFLPs"). RFLPs have been widely used in human and animal genetic analyses (Glassberg, J., UK patent Application 2135774; Skolnick, M.H. et al, Cytogen. Cell Genet. 52:58-67 (1982); Botstein, D. et al, Ann. J. Hum. Genet. 52:314-331 (1980); Fischer, S.G et al. (PCT Application WO90/13668); Uhlen, M., PCT Application WO90/11369)). The role of TIGR in glaucoma pathogenesis indicates that the presence of genetic alterations (e.g., DNA polymoφhisms) that affect the TIGR response can be employed to predict glaucoma . A preferred method of achieving such identification employs the single-strand conformational polymoφhism (SSCP) approach. The SSCP technique is a method capable of identifying most sequence variations in a single strand of DNA, typically between 150 and 250 nucleotides in length (Elles, Methods in Molecular Medicine: Molecular Diagnosis of Genetic Diseases, Humana Press (1996), herein incoφorated by reference); Orita et al, Genomics 5: 874- 879 (1989), herein incoφorated by reference). Under denaturing conditions a single strand of DNA will adopt a conformation that is uniquely dependent on its sequence conformation. This conformation usually will be different, even if only a single base is changed. Most conformations have been reported to alter the physical configuration or size sufficiently to be detectable by electrophoresis. A number of protocols have been described for SSCP including, but not limited to Lee et al, Anal. Biochem. 205: 289-293 (1992), herein incoφorated by reference; Suzuki et al, Anal. Biochem. 192: 82-84 (1991), herein incoφorated by reference; Lo et al, Nucleic Acids Research 20: 1005-1009 (1992), herein incoφorated by reference; Sarkar et al, Genomics 13: 441-443 (1992), herein incoφorated by reference). In accordance with this embodiment of the invention, a sample DNA is obtained from a patient. In a preferred embodiment, the DNA sample is obtained from the patient's blood. However, any source of DNA may be used. The DNA is subjected to restriction endonuclease digestion. TIGR is used as a probe in accordance with the above-described RFLP methods. By comparing the RFLP pattern of the TIGR gene obtained from normal and glaucomatous patients, one can determine a patient's predisposition (prognosis) to glaucoma. The polymoφhism obtained in this approach can then be cloned to identify the mutation at the coding region which alters the protein's structure or regulatory region of the gene which affects its expression level. Changes involving promoter interactions with other regulatory proteins can be identified by, for example, gel shift assays using HTM cell extracts, fluid from the anterior chamber of the eye, serum, etc. Interactions of TIGR protein in glaucomatous cell extracts, fluid from the anterior chamber of the eye, serum, etc. can be compared to control samples to thereby identify changes in those properties of TIGR that relate to the pathogenesis of glaucoma. Similarly such extracts and fluids as well as others (blood, etc.) can be used to diagnosis or predict steroid sensitivity. Several different classes of polymoφhisms may be identified through such methods. Examples of such classes include: (1) polymoφhisms present in the TIGR cDNA of different individuals; (2) polymoφhisms in non-translated TIGR gene sequences, including the promoter or other regulatory regions of the TIGR gene; (3) polymoφhisms in genes whose products interact with TIGR regulatory sequences; (4) polymoφhisms in gene sequences whose products interact with the TIGR protein, or to which the TIGR protein binds. In an alternate sub-embodiment, the evaluation is conducted using oligonucleotide "probes" whose sequence is complementary to that of a portion of SEQ ED NO: 1, SEQ ID NO: 2 SEQ ID NO: 3, SEQ ED NO: 4, or SEQ ED NO: 5. Such molecules are then incubated with cell extracts of a patient under conditions sufficient to permit nucleic acid hybridization. In one sub-embodiment of this aspect of the present invention, one can diagnose or predict glaucoma, related diseases and steroid sensitivity by ascertaining the TIGR response in a biopsy (or a macrophage or other blood cell sample), or other cell sample, or more preferably, in a sample of bodily fluid (especially, blood, serum, plasma, tears, buccal cavity, etc.). Since the TIGR gene is induced in response to the presence of glucocorticoids, a highly preferred embodiment of this method comprises ascertaining such TIGR response prior to, during and/or subsequent to, the administration of a glucocorticoid. Thus, by way of illustration, glaucoma could be diagnosed or predicted by determining whether the administration of a glucocorticoid (administered topically, intraocularly, intramuscularly, systemically, or otherwise) alters the TIGR response of a particular individual, relative to that of normal individuals. Most preferably, for this puφose, at least a "TIGR gene-inducing amount" of the glucocorticoid will be provided. As used herein, a TIGR gene-inducing amount of a glucocorticoid is an amount of glucocorticoid sufficient to cause a detectable induction of TIGR expression in cells of glaucomatous or non- glaucomatous individuals. Generating Cells, Vectors, and Expressed Proteins Using Agents of the Invention The present invention also relates to methods for obtaining a recombinant host cell, especially a mammalian host cell, comprising introducing into a host cell exogenous genetic material comprising a nucleic acid of the invention. The present invention also relates to an insect cell comprising a recombinant vector having a nucleic acid of the invention. The present invention also relates to methods for obtaining a recombinant host cell, comprising introducing exogenous genetic material comprising a nucleic acid of the invention via homologous recombination. Through homologous recombination, the promoter and 5' flanking sequences of the TIGR gene described here can be used in gene activation methods to produce a desired gene product in host cells (see, for example, U.S. Patent 5,733,746, specifically incoφorated herein by reference). The specific expression of the TIGR gene in TM cells afforded by the TIGR promoter region DNA can, thus, be transferred via homologous recombination to express other gene products in a similar fashion. Some of these other gene products may be therapeutic proteins that address diseases related to increased IOP or glaucoma. Methods for selecting and using the promoter and 5' flanking sequence for the gene targeting technique involved in the gene activation method are known in the art. Depending upon the nature of the modification and associated targeting construct, various techniques may be employed for identifying targeted integration. Conveniently, the DNA may be digested with one or more restriction enzymes and the fragments probed with an appropriate DNA fragment, which will identify the properly sized restriction fragment associated with integration. The sequence to be integrated into the host may be introduced by any convenient means, which includes calcium precipitated DNA, spheroplast fusion, transformation, electroporation, biolistics, lipofection, microinjection, or other convenient means. Where an amplifiable gene is being employed, the amplifiable gene may serve as the selection marker for selecting hosts into which the amplifiable gene has been introduced. Alternatively, one may include with the amplifiable gene another marker, such as a drug resistance marker, e.g. neomycin resistance (G418 in mammalian cells), hygromycin resistance etc., or an auxotrophy marker (HIS3, TRP1, LEU2, URA3, ADE2, LYS2, etc.) for use in yeast cells. For example, homologous recombination constructs can be prepared where the amplifiable gene will be flanked, normally on both sides, with DNA homologous with the DNA of the target region, here the TIGR sequences. Depending upon the nature of the integrating DNA and the puφose of the integration, the homologous DNA will generally be within 100 kb, usually 50 kb, preferably about 25 kb, of the transcribed region of the target gene, more preferably within 2 kb of the target gene. The homologous DNA may include the 5'-upstream region outside of the transcriptional regulatory region or enhancer sequences, transcriptional initiation sequences, adjacent sequences, or the like. The homologous region may include a portion of the coding region, where the coding region may be comprised only of an open reading frame or of combination of exons and introns. The homologous region may also comprise all or a portion of an intron, where all or a portion of one or more exons may also be present. Alternatively, the homologous region may comprise the 3'-region, so as to comprise all or a portion of the transcriptional termination region, or the region 3' of this region. The homologous regions may extend over all or a portion of the target gene or be outside the target gene comprising all or a portion of the transcriptional regulatory regions and/or the structural gene. The integrating constructs may be prepared in accordance with conventional ways, where sequences may be synthesized, isolated from natural sources, manipulated, cloned, ligated, subjected to in vitro mutagenesis, primer repair, or the like. At various stages, the joined sequences may be cloned, and analyzed by restriction analysis, sequencing, or the like. Usually during the preparation of a construct where various fragments are joined, the fragments, intermediate constructs and constructs will be carried on a cloning vector comprising a replication system functional in a prokaryotic host, e.g., E. coli, and a marker for selection, e.g., biocide resistance, complementation to an auxotrophic host, etc. Other functional sequences may also be present, such as polylinkers, for ease of introduction and excision of the construct or portions thereof, or the like. A large number of cloning vectors are available such as pBR322, the pUC series, etc. These constructs may then be used for integration into the primary host. DNA comprising a nucleic acid of the invention can be introduced into a host cell by a variety of techniques that include calcium phosphate/DNA co-precipitates, microinjection of DNA into the nucleus, electroporation, yeast protoplast fusion with intact cells, transfection, polycations, e.g., polybrene, polyornithine, etc., or the like. The DNA may be single or double stranded DNA, linear or circular. The various techniques for transforming cells are well known (see Keown et al., Methods Enzymol (1989), Keown et al., Methods Enzymol. 185:521-531 (1990); Mansour et al, Nature 556:348-352, (1988); all of which are herein incoφorated by reference in their entirety). In a preferred aspect, the invention relates to recombinant insect vectors and insect cells comprising a nucleic acid of the invention. In a particularly preferred aspect, a Baculovirus expression vector is used, introduced into an insect cell, and recombinant TIGR protein expressed. The recombinant TIGR protein may be the full length protein from human TM endothelial cells, a fusion protein comprising a substantial fragment of the full length protein, for example, at least about 20 contiguous amino acids to about 100 contiguous amino acids of the full length protein, or a variant TIGR protein or fusion protein produced by site-directed mutagenesis, DNA shuffling, or a similar technique. Generally, the variant TIGR proteins and the fusion proteins will retain at least one structural or functional characteristic of the full length TIGR protein, such as the ability to bind the same antibody, the presence of the substantially similar leucine zipper region, or the ability to bind the same ligand or receptor on TM cells (see Nguyen et al, J. Biol. Chem. 273:6341-6350 (1998), specifically incoφorated herein by reference). Nucleic acids comprising the leucine zipper-encoding regions of the TIGR gene can be identified by methods known in the art and can be used in combination with recombinant or synthetic methods to create ligand-receptor assays. Examples of the preferred, recombinant insect vector, host cell, and TIGR protein of the invention were generated by ligating TIGR cDNA into the PVL1393 vector [I vitrogen]. This vector was transferred into Sf9 cells, the TIGR protein expressed and then purified (see U.S. Patent 5,789,169 and Nguyen et al, J. Biol. Chem. 273:6341-6350 (1998), both of which are specifically incoφorated herein by reference in their entirety). An SDS-PAGE gel of the resulting proteins showed protein bands in the 55 kDa range, which were sequenced to confirm correct identity. In preferred embodiments of the vectors, cells and related methods of the invention, a TIGR fusion protein with GFP (green fluorescent protein) can be expressed in a TM cell line (see Nguyen, et al, J. Biol. Chem. 273:6341-6350 (1998) and the references cited therein for primary TM cell culture and transfection methods). Transformed, cultured TM cells at log phase were transfected with a TIGR-GFP fusion protein-encoding vector. The vector includes the CMV promoter to allow high expression, TIGR cDNA from the first ATG to the end of the protein- encoding region, a fluorescent protein tag (GFP) fused to the carboxy terminus of the TIGR- encoding sequence, and the G418 resistance gene. These elements, and their use, is known in the art or provided by this disclosure and its incoφorated references. The construct is termed TIGR 1 -GFP. The transfection was performed using calcium phosphate or Lipofectin techniques, as known in the art. Incubation at growth condition of 37°C, 8% CO , for 6-18 hours followed. After the transfection, the DNA media was replaced by fresh growth media including G418, which was changed twice weekly, until resistant colonies of cells outgrew the monolayer cells (about 10-15 days). The cell colonies were collected and propagated several passes to select for resistant, transformed cells. The expression of fluorescent TIGR-GFP fusion protein was tested for after several passes. One out of twenty selected colonies expressed high levels of the TIGR- GFP fusion protein. In other preferred embodiments of the cells and methods of the invention, a transformed, immortalized TM cell line can be prepared using an SV40-derived vector. Primary cultured TM cells are transfected with an SV40 vector with a defect in the PsvOri, as known in the art. Briefly, primary cultured cells at log phase are transfected with PsvOri DNA using calcium phosphate or Lipofectin and incubated at growth condition of 37°C, 8% C0 2 for 6-18 hours. The DNA media was replaced by fresh growth media and changed twice weekly until colonies of immortalized cells outgrow the dying monolayer (about 10-15 days). The cell colonies are collected and propagated several passes to select for transformed cells. III. Methods of Administration Some of the agents of the present invention can be formulated according to known methods to prepare pharmacologically acceptable compositions, whereby these materials, or their functional derivatives, having the desired degree of purity are combined in admixture with a physiologically acceptable carrier, excipient, or stabilizer. Such materials are non-toxic to recipients at the dosages and concentrations employed. The active component of such compositions may be agents, analogs or mimetics of such molecules. Where nucleic acid molecules are employed, such molecules may be sense, antisense or triplex oligonucleotides of the TIGR promoter, TIGR cDNA, TIGR intron, TIGR exon or TIGR gene. A composition is said to be "pharmacologically acceptable" if its administration can be tolerated by a recipient patient. An agent is physiologically significant if its presence results in a detectable change in the physiology of a recipient patient. Suitable vehicles and their formulation, inclusive of other human proteins, e.g., human serum albumin, are described, for example, in Remington's Pharmaceutical Sciences (16 th ed., Osol, A., Ed., Mack, Easton PA (1980)). If the composition is to be water soluble, it may be formulated in a buffer such as phosphate or other organic acid salt preferably at a pH of about 7 to 8. If the composition is only partially soluble in water, it may be prepared as a microemulsion by formulating it with a nonionic surfactant such as Tween, Pluronics, or PEG, e.g., Tween 80, in an amount of, for example, 0.04-0.05% (w/v), to increase its solubility. The term "water soluble" as applied to the polysaccharides and polyethylene glycols is meant to include colloidal solutions and dispersions. In general, the solubility of the cellulose derivatives is determined by the degree of substitution of ether groups, and the stabilizing derivatives useful herein should have a sufficient quantity of such ether groups per anhydroglucose unit in the cellulose chain to render the derivatives water soluble. A degree of ether substitution of at least 0.35 ether groups per anhydroglucose unit is generally sufficient. Additionally, the cellulose derivatives may be in the form of alkali metal salts, for example, the Li, Na, K or Cs salts. Optionally other ingredients may be added such as antioxidants, e.g., ascorbic acid; low molecular weight (less than about ten residues) polypeptides, e.g., polyarginine or tripeptides; proteins, such as serum albumin, gelatin, or immunoglobulins; hydrophilic polymers such as polyvinyl pyrrolidone; amino acids, such as glycine, glutamic acid, aspartic acid, or arginine; monosaccharides, disaccharides, and other carbohydrates including cellulose or its derivatives, glucose, mannose, or dextrins; chelating agents such as EDTA; and sugar alcohols such as mannitol or sorbitol. Additional pharmaceutical methods may be employed to control the duration of action. Controlled or sustained release preparations may be achieved through the use of polymers to complex or absorb the TIGR molecule(s) of the composition. The controlled delivery may be exercised by selecting appropriate macromolecules (for example polyesters, polyamino acids, polyvinyl pyrrolidone, ethylenevinylacetate, methylcellulose, carboxymethylcellulose, or protamine sulfate) and the concentration of macromolecules as well as the methods of incoφoration in order to control release. Sustained release formulations may also be prepared, and include the formation of microcapsular particles and implantable articles. For preparing sustained-release compositions, the TIGR molecule(s) of the composition is preferably incoφorated into a biodegradable matrix or microcapsule. A suitable material for this puφose is a polylactide, although other polymers of poly-(a-hydroxycarboxylic acids), such as poly-D-(-)-3-hydroxybutyric acid (EP 133,988A), can be used. Other biodegradable polymers include poly(lactones), poly(orthoesters), polyamino acids, hydrogels, or poly(orthocarbonates) poly(acetals). The polymeric material may also comprise polyesters, poly(lactic acid) or ethylene vinylacetate copolymers. For examples of sustained release compositions, see U.S. Patent No. 3,773,919, EP 58,481A, U.S. Patent No. 3,887,699, EP 158,277 A, Canadian Patent No. 1176565, Sidman, U. et al, Biopolymers 22:547 (1983), and Langer, R. et al, Chem. Tech. 12:98 (1982). Alternatively, instead of incoφorating the TIGR molecule(s) of the composition into polymeric particles, it is possible to entrap these materials in microcapsules prepared, for example, by coacervation techniques or by interfacial polymerization, for example, hydroxymethylcellulose or gelatine-microcapsules and poly(methylmethacylate) microcapsules, respectively, or in colloidal drug delivery systems, for example, liposomes, albumin microspheres, microemulsions, nanoparticles, and nanocapsules or in macroemulsions. Such techniques are disclosed in Remington's Pharmaceutical Sciences (1980). In an alternative embodiment, liposome formulations and methods that permit intracellular uptake of the molecule will be employed. Suitable methods are known in the art, see, for example, Chicz, R.M. et al. (PCT Application WO 94/04557), Jaysena, S.D. et al (PCT Application WO93/12234), Yarosh, D.B. (U.S. Patent No. 5,190,762), Callahan, M.V. et al (U.S. Patent No. 5,270,052) and Gonzalezro, R.J. (PCT Application 91/05771), all herein incoφorated by reference. Having now generally described the invention, the same will be more readily understood through reference to the following examples which are provided by way of illustration, and are not intended to be limiting of the present invention, unless specified. EXAMPLE 1 Illustrative Single Strand Conformational Polvmoφhism Assay Single strand conformational polymoφhism (SSCP) screening is carried out according to the procedure of Hue et al, The Journal of Investigative Ophthalmology 105.4: 529-632 (1995), herein incoφorated by reference.

SSCP primers SK-la, ca2, CA2, Pr+1, Pr-2(4A), Pr+3(4A), SKIXX, and KS6 detect single strand conformational polymoφhisms in this population. An SSCP is detected using SSCP primers Pr+3(4A) and Pr-2(4A). 70 family members of the Klamath Fall, Oregon are screened with these primers and the results are set forth in Table 1.

EXAMPLE 2 TIGR Homologies A novel "myosin-like" acidic protein termed myocilin is expressed predominantly in the photoreceptor cells of retina and is localized particularly in the rootlet and basal body of connecting cilium (Kubota et al, Genomics 41: 360-369 (1997), herein incoφorated by reference). The myocilin gene is mapped to human chromosome Iq23-q24. The coding region of myocilin is 100 percent homologous with TIGR. Homology searches are performed by GCG (Genetics Computer Group, Madison, WI) and include the GenBank, EMBL, Swiss-Prot databases and EST analysis. Using the Blast search, the best fits are found with a stretch of 177 amino acids in the carboxy terminals for an extracellular mucus protein of the olfactory, olfactomedin and three olfactomedin-like species. The alignment presented in Figure 6 shows the ΗGR homology (SEQ ID NO. 27) to an expressed sequence tag (EST) sequence from human brain (ym08hl2.rl)(SEQ ED NO. 28)(The WashU-Merck EST Project, 1995); the Z domain of olfactomedin-related glycoprotein from rat brain (lB426bAMZ)(SEQ ED NO. 29)(Danielson et al, Journal of Neuroscience Research 38: 468-478 (1994), herein incoφorated by reference) and the olfactomedin from olfactory tissue of bullfrogs (ranofm) (SEQ ED NO. 30)(Yokoe and Anholt, Proc. Natl. Acad. Sci. 90: 4655-4659 (1993), herein incoφorated by reference; Snyder and Anholt, Biochemistry 30: 9143-9153 (1991), herein incoφorated by reference). These domains share very similar amino acid positions as depicted in the consensus homology of Figure 6 (SEQ ID NO. 31), with the exception being the truncated human clone in which the position with respect to its full length sequence has not been established. No significant homology is found for the amino termini of these molecules. EXAMPLE 3 Identification of TIGRmtl 1 DNA samples were obtained from individuals noted for having elevated IOP in response to the administration of topical corticosteroids. Typically, the "Armaly" criteria is used to register IOP changes. Genomic DNA from blood or buccal swabs were used for PCR amplification. The PCR reaction includes 95° C for 30 sec, for denaturation, 55° C for30 sec, for annealing and 72° C for 30 sec for synthosis. The reaction was performed for 30 cycles with an additional cycle of 72° C for 5 min at the end. The primer pair for the PCR reaction can include any pair that amplifies a specific region targeted for analyzing mutants or polymoφhisms. Preferably, the amplified region will be from about 500 base pairs 5' of the start of transcription to the start of translation. More preferably, it will include an amplified region about 200 bp 5' of the start of transcription to about 10 base pairs 5' to the start of translation. Methods for determining amplification primer sequences from within a known sequence region are well known in the art. Examplary methods include, but are not limited to, computer generated searches using programs such as Primer3 (www- genome.wi.mit.edu cgi-bin/primer/primer3.cgi), STSPipeline (www-genome.wi.mit.edu/cgi- bin/www-STS_Pipeline), or GeneUp (Pesole, et al, BioTechniques 25:112-123 (1998)). In an especially preferred embodiment, this amplified region will be from position 5044 of SEQ ID NO: 3 to about 5327 of SEQ ED NO: 3, which will thus employ primers of the sequence of about 5044 to about 5066 and the sequence of about 5309 to about 5327 of SEQ ID NO: 3, or the complement. In one embodiment, the complement of the sequence from about 5309 to about 5327 is used as one of the primers and the sequence from about 5044 to about 5066 is used as the other primer. For this example, the following primers were used: forward primer CA-2R (SEQ ID NO: 35 - 5' AACTATTATT GGGGTATGGG) and reverse primer Sk-la (SEQ ID NO: 36 - 5' TTGGTGAGGC TTCCTCTGC). The primers were labeled with a fluorescent dye IRD-800 by Li-Cor Technology and the PCR product (about 300 bp) was denatured by heat and subject to BESS assays to detect mutations. BESS, or Base Excision Sequence Scanning, employed specific restriction enzyme that cleaves T position of single strand DNA. The cleavage will produce DNA fragments that could be observed by acrylamide gels. Based on this, a 'T mutation' will produce different cleavage pattern for the mutated strand compared to the normal strand. Since 95% of mutations involve a T mutation, this method is very practical. In addition to BESS, the amplified fragments can also be sequenced or compared by hybridization methods (microarray hybridization techniques or the sequencing-by-hybridization technique) in order to determine the exact nucleotide sequence, as known in the art. Using this assay, patients exhibiting an increased IOP in response to topical corticosteroid treatments had an elevated level of a T mutation in one particular position, at about 160 bases 5' to the start of the TIGR coding region. The presence of this particular mutation, called TIGRmtl 1, therefore, indicated a specific genetic linkage to steroid sentivity that manifests in atleast a higher risk of increased IOP, and thus glaucoma, in repsonse to steroid treatment. TABLE 3 Subject Duration of CS Treatment IOP (OD/OS) Genotype (mt.l l) 1 1 year 38/30 +/- 2 3 weeks 25/28 +/+ 3 2 weeks 28/28 +/+ CS= corticosteroid, topical treatment (1 year) CS treatment 38/30 mm Hg, OD/OS; (3 weeks) CS treatment 25/28 mm Hg, OD/OS; (2 weeks) CS treatment 28/38 mm Hg, OD/OS The sequence in SEQ ID NO: 33 ( CAAACAGACT TCCGGAAGGT) identifies bases immediately adjacent to the single base polymoφhism, which represents bases 5101 to 5120 of SEQ D NO: 1, except that the underlined C in the TIGRmtl 1 sequence variant is substituted for the 'wild type' T, found in SEQ ED NO: 1. EXAMPLE 4 Verification of Linkage Between TIGRmtl 1 and Risk of Glaucoma Subjects are given standard topical dexamethasone eye drops (0.1%) four times a day, for four weeks. Pre-treatment and post-treatment IOP readings are taken and patients are classified as having high (>16mmHg), intermediate (6-16mmHg) or low (<6mmHg) IOP responses under the "Armaly" criteria. DNA samples are obtained from four subjects having high or intermediate IOP changes. Samples from several non-responder patients were also taken. The DNA samples were analyzed for the presence of the TIGRmtl 1 variant sequence, as discussed above. The results are given in Table 4. TABLE 4 Subject Age Classification CS-IOP Response Genotype (mt.l l) 1 47 OHT Intermediate +/+ 2 28 POAG High +/+ 3 46 POAG/OHT High +/+ 4 15 Stevens-Johnson High +/+ 5 Nr Normal Low -/- 6 Nr Normal Low -/- 7 Nr Normal Low -/- OHT = Ocular Hypertensive (began with a mild IOP elevation, no POAG) POAG = Original diagnosis is primary open-angle glaucoma POAG/OHT = Converted to POAG, from original diagnosis OHT The data obtained indicates the association of TIGRmt.l l and the response to topical CS. Clearly, all the subjects with clinically identifiable responses to the CS treatment possessed the TIGRmtl 1 variant sequence while none of the subjects with the 'wild type' sequence, or a sequence that did not possess the TIGRmtl 1 variant, did not. While the invention has been described in connection with specific embodiments thereof, it will be understood that it is capable of further modifications and this application is intended to cover any variations, uses, or adaptations of the invention following, in general, the principles of the invention and including such departures from the present disclosure as come within known or customary practice within the art to which the invention pertains and as may be applied to the essential features herein before set forth and as follows in the scope of the appended claims. EXAMPLE 5 TIGR 5' Region /Promoter Activity Assays and Methods for Detecting Cell Components Binding to TIGR Gene Sequences The 283 base 5' fragment of the TIGR 5' region (SEQ ID NO: 37) is amplified from genomic DNA of a normal human subject as discusssed in Example 3. The DNA is cloned into a pSEAP vector (Clontech, CA) so that transcription was under the control of the TIGR sequences. More specifically, pSEAP2 -enhancer vector is digested with Srfl to produce a blunt end. The 283 bp fragment is blunt end ligated to the vector using T4 ligase for 2 hours. The vector is transfected into DH5 cells to establish a plasmid clone, TMRE-1/pSEAP. PCR sequencing is used to verify the clone sequence as correct. Similarly, the equivalent genomic fragment amplified from a steroid responder sample, identified as mutant TIGR.mtl 1, is cloned in pSEAP2-enhancer and called clone TIGR.mtl 1/pSEAP. HTM cells, Cos cells (COS-7), and HeLa cells (HeLa 229) are seeded at 10 6 cells per well and incubated with 1 ug of the plasmid DNA to transfect using Lipofectin reagent (GEBCO, LifeTechnologies, MD). Some samples of cells were also treated with dexamethasone (DEX). Then, 24, 48, and 72 hours after transfection, AP activity was measured. Cells are collected using a buffer containing L-homoarginine and the chemiluminescent substrate CSPD and a chemiluminescent enhancer added to the samples. The expression levels are then recorded using a luminometer or by brief exposure to X-ray film. The results show that AP activity is present in HTM transfected cells within 24 hours and that the levels increase over 50 fold 48 and 72 hours after transfection. In contrast, HeLa and Cos cells show insignificant AP activity at the same time points. To detect cell components that specifically bind to TIGR sequences, the amplified genomic fragments are suitably labeled, such as by end-labeling with 32 PdATP using T4 Kinase. Labeled fragments are then incubated with nuclear extracts of TM cells, +/- treatment with DEX (500nM) for 10 days, and HeLa cell extract (Stratagene, CA) for 15 minutes at 0°C. The samples are then run on a low ionic strength, non-denaturing polyacrylamide gel. The gel is then dried and exposed to X-ray film overnight. The shift in mobility, apparent in Figure 9, demonstrates the presence of DNA binding components from HTM cells, and that treatment with DEX changes the amount or strength of binding.
