THE NYMPH OF GOMPHUS QUADRICOLOR WALSH (ODONATA)
Authors: Walker E. M.
Published: January 2010

On May 29, 1926, the writer found several Gomphus nymphs on the muddy bottom of the Credit river at Erindale, Ont. It was on a quiet pond-like part of the river, where there are patches of cat-tails (Typha latifolia L.) and some other emergent plants, but only a few yards below a considerable stretch of shallow rapids.

THE SUBFAMILY LYCAOTINAE IN NORTH AMERICA (HYMENOPTERA, TENTHREDINIDAE)
Authors: Ross Herbert H.
Published: January 2010

The genus Lycaota was placed by MacGillivray (1908) in a separate subfamily closely related to the Tenthredininae. Rohwer in 1911, transferred it to the subfamily Blennocampinae (Empriinae of Rohwer) on the basis of the position of the medio-cubital cross-vein. A study of the Selandriinae, Emphytinae and Blennocampinae indicates very strongly that the three subfamilies form a compact unit and that the predicellate condition of the first anal cell in the Blennocampinae arose from the condition existing in the Selandriinae and Emphytinae, not from the condition exhibited by Lycaota, which is very typical of the condition found in a large number of the Tenthredininae.

OUR IGNORANCE CONCERNING INSECTS
Authors: Lutz Frank E.
Published: January 2010

That, my friends, completes the serious part of what I came all the way from New York to say. Our ignorance concerning insects does not depress me because I feel certain that we shall learn. The insect menace does not frighten me because I believe that we can overcome it if we stop our calamity howling and get dorvn to constructive fundamental rvork. In what follows I invite you to join with me in some of the excursions of a museum man who has had the curious Museum experience of having had charge for more than twenty years of a large taxonomic collection without ever describing a new species or changing the name of an old one.
THE LIFE-HISTORY OF SCHISTOCERCA LINEATA SCUD
Authors: Criddle Norman
Published: January 2010

The lined grasshopper, Schistocerca lineata Scud., is the only one of the genus met with in the Prairie Provinces, although it has as relations, several famous locusts of the Old World and South America including the desert locust, Schistocerca gregaria Forst., and S. paranensis Burm. Indeed there is something in the flight and other actions of this insect which separates it from its associates as an aristocrat and most of us seeing it for the first time would readily proclaim “This is a locust”. Despite its aristocratic ancestry, however, the lined grasshopper is little better than a hermit, and in Canada it is restricted in distribution to the southern slopes of a few hot coulies in Alberta.
THE BLACKFLY, SIMULIUM VENUSTUM SAY, AND A PROTOZOON DISEASE OF DUCKS
Authors: Twinn C. R.
Published: January 2010

In 1915 Wickware reported on an investigation at Ottawa, of a serious disease which had appeared anlong ducks. Examination of the blood of affected ducks showed the presence of a protozoon parasite which Wickware named Leucocytozoon anatis. O'Roke (1930) reports that the disease is apparently not harmful to adult ducks, but is pathogenic to ducklings, the mortality being 35 per cent in the cases studied.
NEW SPECIES OF CARPHOBORUS EICH. WITH KEY TO SPECIES NORTH OF MEXICO (COLEOPTERA-SCOLYTIDAE)
Authors: Bruck C. R.
Published: January 2010

While making an intensive study of the bark beetles of Western North America, I noticed that two of the species in the genus Carphoborus were new. Since the last key to the species of this genus has been compiled (Swaine, 1918) Dr. Swaine has described five new species which with my two would more than double the number in the genus. I therefore feel that a new key should be made.

I am indebted to the Museum of the California Academy of Sciences for the use of its collection of this genus, and to Dr. E. C. Van Dyke of the University of California for his helpful criticisms.

Published: January 2010

This wasp has been reported capturing as prey the western harvester or
mound-building prairie ant, Pogonomyrmex

the posterior end of the abdomen to its nest. During the month of September,
1932, the writer was again privileged to wasp and to make some further
observations.
NOTES ON THE HEPTAGENINE SPECIES DESCRIBED BY CLEMENS FROM THE GEORGIAN BAY REGION, ONT. (EPHEMEROP.)
Authors: McDunnough J.
Published: January 2010

In order to clear up certain doubts which had arisen regarding the identity of several Heptagenine species, placed at present in the genus Ecdyonurus, and described by Clemens from material collected in the Go Home Bay region of the Georgian Bay (1913, Can. Ent. XLV, 246-262), Mr. G. S. Walley spent the months of June and July, 1932, in this same locality, collecting and breeding nymphal material. In the group in question he was most successful in securing both nymphs and bred adults of all the species listed by Clemens; the present article, therefore, is presented with a view not only of rendering definitely recognizable certain of Clemens' species in which the original diagnoses were rather brief and incomplete, but also of correcting some specific misidentifications occurring in Clemens' paper.

THE NYMPHS OF THE CANADIAN SPECIES OF OPHIOGOMPHUS ODONATA, GOMPHIDAE
Authors: Walker E. M.
Published: January 2010

Although the species of Ophiogomphus are well defined in the adult stage their nymphs are extremely uniform in structure and are difficult to separate. This is perhaps not remarkable in view of the similarity of their habitats, all the species being shallow burrowers in running streams, usually clear, with a sandy or pebbly bottom, where they occupy the edges of currents, gentle riffles, or pools at the foot of rapids.

A NEW BARK BEETLE FROM SOUTHERN CALIFORNIA
Authors: Bruck C. R.
Published: January 2010

While studying some material sent to me from the southern part of Caliicrnia, there came to my notice this very small species of bark beetle, which interested me greatly. While it is not of much economic importance, as are other members of the subfamily Hylesininae, it is of interest because of its host relationship to Chaetophloeus hystrix (Lec.). Both occur on Rhus integrifolia.

This is a new species and a description of the same follows.
AQUATIC ICHNEUMON-FLIES
Authors: Cushman R. A.
Published: January 2010

In the May, 1932, number of the Canadian Entomologist, G. Chagnon records observing an insect resembling an ichneumonid walking down the stem of an aquatic plant into the water.

This habit in the genus Agriotypus has been known for many years. These insects are parasitic in the cases of caddis flies, entering the water by walking down the surfaces of stones or plants to parasitize their hosts.
LADYBIRD BEETLES AS PREDATORS OF THE POTATO PSYLLID
Authors: Knowlton George E.
Published: January 2010

During the spring of 1933, an adult convergent ladybird beetle, Hippodamia convergens Guerin, was placed in a 3-dram homeopathic vial with a number of nymphs of the potato psyllid, Paratrioza cockerelli (Sulc). The ladybird immediately grabbed a psyllid nymph and began to eat it. Ten fifth-instar psyllid nymphs were eaten by this predaceous beetle during the one and one-half hours that it was caged with the nymphs. It was noted that moving nymphs were taken more quickly than those at rest, but the beetle showed no reluctance at taking the scale-like nymphs which were quietly feeding.
NEW SPECIES OF HYPOPHLOEUS (COLEOPTERA)
Authors: Wallis J. B.
Published: January 2010

The genus Hypophloeus contains a number of undescribed species but until the relation of certain forms as sexes has been established or disproved it is probably as well to refrain from describing species closely allied to parallelus.

The three following seem, however, to be so clearly distinct that they should be made known.
APARITY AMONG THE ORIBATIDAE (ACARINA)
Authors: Jacot Arthur Paul
Published: January 2010

Aparity is that development in reproduction wherein the adult mother retains the eggs instead of laying them. The result is that the young hatch in the mother's body and are forced to feed on her tissues until they have eaten their way out. Such a condition might be construed as parasitism on the adult mother. Since the phenomenon is brought on by the parent and is forced upon the young, it can hartdly be called parasitism, unless the old term obligate parasite is given a new meaning.

Through the courtesy of Professor R. A. Cooley, Dr. William C. Cook, and Professor G. Allen Mail of the Montana Agricultural Experiment Station, from 1927 to 1931 I examined various portions of the station's collection of Coleoptera. In view of the paucity of Montana records of this order it seemed desirable to publish a list of the species obtained in this way.
ADDITIONAL NOTES ON TROPAEA LUNA (LEPID)

NOTES ON THE HABITS OF INJURIOUS GRASSHOPPERS IN MANITOBA
Authors: Criddle Norman
Published: January 2010

Any evidence which would help us to forecast grasshopper outbreaks, or to anticipate and check them before they become acute, is worth considering and on this account the recently annunciated “phase” theory, and the still later “reservation” theory, should secure the careful consideration of American entomologists.
ACARIASIS OF THE WHITE RAT (RATTUS NORVEGICUS FORM ALBINUS)
Authors: Skidmore Louis V.
Published: January 2010

In August 1929 the writer examined a colony of white rats which were being used in a nutrition experiment. These rats were scratching themselves about the head, nose and neck. Many had small dry scabs on the head, about the ears, and upper sides of the neck. Some had bloody scabs due to bleeding caused by severe scratching. Parasitic infestation was suspected and microscopic examination showed the presence of mites.
A NEW NEOBELLAMIRA (COLEOP.)
Authors: Hopping Ralph
Published: January 2010

The genus Neobellamira was erected by Swaine and Hopping for Strangalia delicata Lec., since it was apparently not congeneric with Leconte's genus Strangalia, now Strangalina Auriv. Neobellamira differs not only on the male characters but on the poriferous areas of the distal segments of the antennae which become hardly more than mere punctures or are entirely absent. In Strangalina these areas are strongly developed.

A CONTRIBUTION TO THE TECHNIQUE FOR PROPAGATION OF CHELONUS ANNULIPES WESM.; AN IMPORTED PARASITE OF THE EUROPEAN CORN BORER
Authors: Wishart Geo. , van Steenburgh W. E.
Published: January 2010

The matter offered for consideration in this paper deals entirely with one phase of the rearing of Chelonus annulipes Wesm., a larval parasite ovipositing in the egg of the European Corn Borer, Pyrausta nubilalis Hubn. This phase, the effect on the percentage of successful parasitism, of the age of the host eggs at the time of attack, is one of the more important factors determining the success or failure of laboratory rearing and distribution of this species.

A NEW SPECIES OF THE GENUS INCISALIA (LEPIDOPTERA)
Authors: Sheppard A. C.
Published: January 2010

On June 12th, 1932, while collecting along a roadway running through a large swampy area at Lanoraie, P. Q., on the north side of the St. Lawrence River and about forty miles east of Montreal, I obtained two specimens of the above genus, which on comparison with allied species could not be matched, these were later submitted to Dr. J. McDunnough at Ottawa, Ont., who kindly examined them for me and found that they did not seem to fit in with any of the species known to him but due to their rather worn condition it was suggested that I try to obtain some better specimens another year before making any definite determination of them.
A NEW SPECIES OF HOPPINGIANA FROM BRITISH COLUMBIA. (COLEOPTERA: MELYRIDAE)
Authors: Blaisdell Frank E.
Published: January 2010

In January of 1924 (Can. Ent., vol. LVI, No. I, p. 2.), I created the genus Hoppingiana to receive a species of Melyrid that did not fit into any of the previous generic definitions. Of late considerable discussion has arisen over the possibility that Hoppingiana brevilabris Blais. is the true Dasytes hudsonicus of LeConte. My male specimen of hudsonicus Lec. was received from Wickham and was collected in the alpine regions of Colorado.

Published: January 2010

The Odonatan Fauna of the Big Bend Region of Trans-Pecos, Texas, although not an extensive one, is yet very interesting and practically unknown. For these reasons it seems worth while to record the observations and the specimens collected during the period from September, 1928, to July, 1930, and September, 1931, while the writer was stationed at the Pink Bollworm Laboratory at Presidio, Texas.

In the writer's treatise on the North American species of the genus Aeschna (Walker, '12) the nymph of A. juncea L. was described from exuviae collected by the late Dr. F. Ris at Cierfs, Switzerland. One of the exuviae was accompanied by a teneral imago. A single female exuvia from Nipigon, Ont., very closely resembling the Swiss specimens, was tentatively referred in the same work (p. 98) to A. subarctica Wlk. rather than juncea, although both species were flying at the spot where the exuvia was found.

The mountain pine beetle (Dendroctonus monticolae Hopk.) has killed millions of trees during the past ten years in Montana, Idaho, and eastern Washington. It was during a serious epidemic of this beetle that the writer undertook a study of the economic importance and biology of its enemies in an effort to determine what insects were the most beneficial and to work out their seasonal history so that artificial control work could be instituted, if possible, at a time that would destroy fewer beneficial insects.

CD72 Negatively Regulates KIT-Mediated Responses in Human Mast Cells
Authors: Kataoka Tatsuki R. , Kumanogoh Atsushi , Bandara Geethani , Metcalfe Dean D. , Gilfillan Alasdair M.
Published: January 2010

KIT activation, through binding of its ligand, stem cell factor, is crucial for normal mast cell growth, differentiation, and survival. Furthermore, KIT may also contribute to mast cell homing and cytokine generation. Activating mutations in KIT lead to the dysregulated mast cell growth associated with the myeloproliferative disorder, mastocytosis. We investigated the potential of downregulating such responses through mast cell inhibitory receptor activation. In this study, we report that the B cell-associated ITIM-containing inhibitory receptor, CD72, is expressed in human mast cells. Ligation of CD72 with the agonistic Ab, BU40, or with recombinant human CD100 (rCD100), its natural ligand, induced the phosphorylation of CD72 with a resulting increase in its association with the tyrosine phosphatase SH2 domain-containing phosphatase-1. This, in turn, resulted in an inhibition of KIT-induced phosphorylation of Src family kinases and extracellular-regulated kinases (ERK1/2). As a consequence of these effects, KIT-mediated mast cell proliferation, chemotaxis, and chemokine production were significantly reduced by BU40 and rCD100. Furthermore, BU40 and rCD100 also downregulated the growth of the HMC1.2 human mast cell line. Thus, targeting CD72 may provide a novel approach to the suppression of mast cell disease such as mastocytosis.
Absence of SHIP-1 Results in Constitutive Phosphorylation of Tank-Binding Kinase 1 and Enhanced TLR3-Dependent IFN-β Production
Authors: Gabhann Joan Ní , Higgs Rowan , Brennan Kiva , Thomas Warren , Damen Jacqueline E. , Ben Larbi Nadia , Krystal Gerald , Jefferies Caroline A.
Published: January 2010

Autoimmune diseases, such as systemic lupus erythematosus and rheumatoid arthritis, result from a loss of tolerance to self-antigens and immune-mediated injury precipitated by the overproduction of type I IFN and inflammatory cytokines. We have identified the inositol 5′ phosphatase SHIP-1 as a negative regulator of TLR3-induced type I IFN production. SHIP-1–deficient macrophages display enhanced TLR-induced IFN-β production, and overexpression of SHIP-1 negatively regulates the ability of TLR3 and its adaptor, Toll/IL-1 receptor domain-containing adaptor-inducing IFN-β, to induce IFN-β promoter activity, indicating that SHIP-1 negatively regulates TLR-induced IFN-β production. Further dissection of the IFN-β pathway implicates TANK-binding kinase 1 (TBK1) as the target for SHIP-1. Critically, in the absence of SHIP-1, TBK1 appears to be hyperphosphorylated both in unstimulated cells and following TLR3 stimulation. In addition, TBK1 appears to be constitutively associated with Toll/IL-1 receptor domain-containing adaptor-inducing IFN-β and TNFR-associated factor 3 in SHIP-1 deficient cells, whereas in wild-type cells this association is inducible following TLR3 stimulation. In support of a role for SHIP-1 in regulating complex formation, confocal microscopy demonstrates that TBK1 distribution in the cell is significantly altered in SHIP-1–deficient cells, with more prominent endosomal staining observed, compared with wild-type controls. Taken together, our results point to SHIP-1 as a critical negative regulator of IFN-β production downstream of TLR3 through the regulation of TBK1 localization and activity.

CCL3 is a protein of the CC chemokine family known to be important for T cell recruitment in inflammatory diseases. The aim of the current study was to evaluate the effects and putative mechanism of action of evasin-1, a novel CCL3-binding protein, in the pathogenesis of acute graft-versus-host disease (GVHD). GVHD was induced by the transplantation of splenocytes from C57BL/6J to B6D2F1 mice. Treatment of recipient mice with evasin-1 prevented mortality associated with GVHD. This was correlated with reduced weight loss and clinical disease severity. Analysis of the small intestine showed that evasin-1 treatment reduced the histopathological score and decreased levels of IFN-γ and CCL5. Mechanistically, evasin-1 treatment reduced the number of CD4+ and CD8+ T cells infiltrating the small intestine, as assessed by immunohistochemistry, and the adhesion of leukocytes to intestinal venules of recipient mice, as assessed by intravital microscopy. Evasin-1 was also able to decrease liver damage, as seen by reduction of inflammatory infiltrate and IFN-γ levels. Treatment with evasin-1 did not interfere with graft-versus-leukemia. Altogether, our studies demonstrate that CCL3 plays a major role in mediating GVHD, but not graft-versus-leukemia in mice and suggest that blockade of CCL3 with evasin-1 has potential therapeutic application in patients undergoing bone marrow transplantation.
Structural Basis for Lipid-Antigen Recognition in Avian Immunity

CD1 proteins present self- and foreign lipid Ags to activate specific T cells in the mammalian immune system. These T cells play an important role in controlling autoimmune diseases, suppression of tumor growth, and host defense against invading pathogens. Humans use five CD1 isoforms, whereas only two exist in birds. Unlike mammals’ CD1, the structure of chicken CD1-2 showed a primitive lipid-binding groove, suggesting that chicken may only recognize single-chain lipids. In contrast, the crystal structure of the second chicken CD1 isoform, chCD1-1, reported in this study at 2.2 Å resolution, reveals an elaborated binding groove with a dual-pocket, dual-cleft architecture. The A’ and F’ deep pockets are separated from each other, but each is connected to a hydrophobic surface cleft, which may participate in lipid binding. The long endogenous ligand found inside the binding groove of chCD1-1, together with binding data on various glycolipids and mycolic acid, strongly suggest that the unique avian CD1 family could bind long dual- and possibly triacyl-chain lipids.

Robust adaptive output‐feedback control for a class of nonlinear systems with time‐varying actuator faults
Authors: Zhang Zhengqiang , Xu Shengyuan , Guo Yu , Chu Yuming
Published: January 2010

A robust adaptive output‐feedback control scheme is proposed for a class of nonlinear systems with unknown time‐varying actuator faults. Additional unmodelled terms in the actuator fault model are considered. A new linearly parameterized model is proposed. The boundedness of all the closed‐loop signals is established. The desired control performance of the closed‐loop system is guaranteed by appropriately choosing the design parameters. The properties of the proposed control algorithm are demonstrated by two simulation examples. Copyright © 2010 John Wiley & Sons, Ltd.

Published: January 2010

All commercial forms of electronic/optoelectronic technologies use planar, rigid substrates. Device possibilities that exploit bio‐inspired designs or require intimate integration with the human body demand curvilinear shapes and/or elastic responses to large strain deformations. This article reviews progress in research designed to accomplish these outcomes with established, high‐performance inorganic electronic materials and modest modifications to conventional, planar processing techniques. We outline the most well developed strategies and illustrate their use in demonstrator devices that exploit unique combinations of shape, mechanical properties and electronic performance. We conclude with an outlook on the challenges and opportunities for this emerging area of materials science and engineering.

Published: January 2010

Combination of heating modes such as microwaves, convection, and radiant heating can be used to realistically achieve the quality and safety needed for cooking processes and, at the same time, make the processes faster. Physics‐based computational modeling used in conjunction with MRI experimentation can be used to obtain critical understanding of combination heating. The objectives were to: (1) formulate a fully coupled electromagnetics ‐ heat transfer model, (2) use magnetic resonance imaging (MRI) experiments to determine the 3D spatial and temporal variation of temperatures and validate the numerical model, (3) use the insight gained from the model and experiments to understand the combination heating process and to optimize it. The different factors that affect heating patterns during combination heating such as the type of heating modes used, placement of sample, and microwave cycling were considered. Objective functions were defined and minimized for design and optimization. The use of such techniques can lead to greater control and automation of combination heating process benefitting the food process and product developers immensely. © 2010 American Institute of Chemical Engineers AIChE J, 2010

Juvenile polyposis (JP) and hereditary hemorrhagic telangiectasia (HHT) are clinically distinct diseases caused by mutations in SMAD4 and BMPR1A (for JP) and endoglin and ALK1 (for HHT). Recently, a combined syndrome of JP–HHT was described that is also caused by mutations in SMAD4. Although both JP and JP–HHT are caused by SMAD4 mutations, a possible genotype:phenotype correlation was noted as all of the SMAD4 mutations in the JP–HHT patients were clustered in the COOH‐terminal MH2 domain of the protein. If valid, this correlation would provide a molecular explanation for the phenotypic differences, as well as a pre‐symptomatic diagnostic test to distinguish patients at risk for the overlapping but different clinical features of the disorders. In this study, we collected 19 new JP–HHT patients from which we identified 15 additional SMAD4 mutations. We also reviewed the literature for other reports of JP patients with HHT symptoms with confirmed SMAD4 mutations. Our combined results show that although the SMAD4 mutations in JP–HHT patients do show a tendency to cluster in the MH2 domain, mutations in other parts of the gene also cause the combined syndrome. Thus, any mutation in SMAD4 can cause JP–HHT. Any JP patient with a SMAD4 mutation is, therefore, at risk for the visceral manifestations of HHT and any HHT patient with SMAD4 mutation is at risk for early onset gastrointestinal cancer. In conclusion, a patient who tests positive for any SMAD4 mutation must be considered at risk for the combined syndrome of JP–HHT and monitored accordingly. © 2010 Wiley‐Liss, Inc.

Blepharocheilodontic (BCD) syndrome is a rare autosomal‐dominant condition that is characterized by lower eyelid ectropion, upper eyelid distichiasis, euryblepharon, bilateral cleft lip and palate, and conical teeth. It exhibits considerable phenotypic variability among affected individuals. An additional rare associated manifestation is imperforate anus (IA), which has been reported in three cases [Guyuron et al. (1995); J Craniofac Surg 6:392–394; Gorlin et al. (1996); Am J Med Genet 65:109–112; da Silva Lopes et al. (2003); Am J Med Genet Part A 121A:266–270]. Here we report on a family with BCD that includes IA, confirming that anorectal anomalies are a part of BCD syndrome. © 2010 Wiley‐Liss, Inc.

Two brothers, with dissimilar clinical features, were each found to have different abnormalities of chromosome 20 by subtelomere fluorescence in situ hybridization (FISH). The proband had deletion of 20p subtelomere and duplication of 20q subtelomere, while his brother was found to have a duplication of 20p subtelomere and deletion of 20q subtelomere. Parental cytogenetic studies were initially thought to be normal, both by G‐banding and by subtelomere FISH analysis. Since chromosome 20 is a metacentric chromosome and an inversion was suspected, we used anchored FISH to assist in identifying a possible inversion. This approach employed concomitant hybridization of a FISH probe to the short (p) arm of chromosome 20 with the 20q subtelomere probe. We identified a cytogenetically non‐visible, mosaic pericentric inversion of one of the maternal chromosome 20 homologs, providing a mechanistic explanation for the chromosomal abnormalities present in these brothers. Array comparative genomic hybridization (CGH) with both a custom‐made BAC and cosmid‐based subtelomere specific array (TEL array) and a commercially available SNP‐based array confirmed and further characterized these rearrangements, identifying this as the largest pericentric inversion of chromosome 20 described to date. TEL array data indicate that the 20p breakpoint is defined by BAC RP11‐978M13, ∼900 kb from the pter; SNP array data reveal this breakpoint to occur within BAC RP11‐978M13. The 20q breakpoint is defined by BAC RP11‐93B14, ∼1.7 Mb from the qter, by TEL array; SNP array data refine this breakpoint to within a gap between BACs on the TEL array (i.e., between RP11‐93B14 and proximal BAC RP11‐765G16). © 2010 Wiley‐Liss, Inc.
Planar cell polarity pathway genes and risk for spina bifida

Published: January 2010

Spina bifida, a neural tube closure defect (NTD) involving the posterior portion of what will ultimately give rise to the spinal cord, is one of the most common and serious birth defects. The etiology of spina bifida is thought to be multi‐factorial and involve multiple interacting genes and environmental factors. The causes of this congenital malformation remain largely unknown. However, several candidate genes for spina bifida have been identified in lower vertebrates, including the planar cell polarity (PCP) genes. We used data from a case–control study conducted in California to evaluate the association between variation within several key PCP genes and the risk of spina bifida. The PCP genes included in this study were the human homologs of the Xenopus genes Flamingo, Strabismus, Prickle, Dishevelled, and Scrib, two of the homologs of Xenopus Wnt genes, WNT5A and WNT11, and two of the homologs of Xenopus Frizzled, FZD3 and FZD6. None of the 172 SNPs that were evaluated were significantly associated with spina bifida in any racial/ethnic group after correction for multiple testing. However, several SNPs in the PRICKLE2 gene had unadjusted P‐value <0.01. In conclusion, our results, though largely negative, suggest that the PRICKLE2 gene may potentially modify the risk of spina bifida and deserves further investigation. © 2010 Wiley‐Liss, Inc.

The occurrence of an additional ring chromosome 20 is a rare chromosome abnormality, and no common phenotype has been yet described. We report on two new patients presenting with a supernumerary ring chromosome 20 both prenatally diagnosed. The first presented with intrauterine growth retardation and some craniofacial dysmorphism, and the second case had a normal phenotype except for obesity. Conventional cytogenetic studies showed for each patient a small supernumerary marker chromosome (SMC). Using fluorescence in situ hybridization, these SMCs corresponded to ring chromosomes 20 including a part of short and long arms of chromosome 20. Detailed molecular cytogenetic characterization showed different breakpoints (20p11.23 and 20q11.23 for Patient 1 and 20p11.21 and 20q11.21 for Patient 2) and sizes of the two ring chromosomes 20 (13.6 Mb for case 1 and 4.8 Mb for case 2). Review of the 13 case reports of an extra r(20) ascertained postnatally (8 cases) and prenatally (5 cases) showed varying degrees of phenotypic abnormalities. We document a detailed molecular cytogenetic chromosomal breakpoints characterization of two cases of supernumerary ring chromosomes 20. These results emphasize the need to characterize precisely chromosomal breakpoints of supernumerary ring chromosomes 20 in order to establish genotype–phenotype correlation. This report may be helpful for prediction of natural history and outcome, particularly in prenatal diagnosis. © 2010 Wiley‐Liss, Inc.
