Topic: familial glucocorticoid deficiency
Question: What are the genetic changes related to familial glucocorticoid deficiency ?
Answer: Mutations in the MC2R, MRAP, and NNT genes account for the majority of cases of familial glucocorticoid deficiency; mutations in other genes, some known and some unidentified, can also cause this condition.  The MC2R gene provides instructions for making a protein called adrenocorticotropic hormone (ACTH) receptor, which is found primarily in the adrenal glands. The protein produced from the MRAP gene transports the ACTH receptor from the interior of the cell to the cell membrane. When the ACTH receptor is embedded within the cell membrane, it is turned on (activated) by the MRAP protein. Activated ACTH receptor can then attach (bind) to ACTH, and this binding triggers the adrenal glands to produce glucocorticoids. MC2R gene mutations lead to the production of a receptor that cannot be transported to the cell membrane or, if it does get to the cell membrane, cannot bind to ACTH. MRAP gene mutations impair the transport of the ACTH receptor to the cell membrane. Without the binding of the ACTH receptor to its hormone, there is no signal to trigger the adrenal glands to produce glucocorticoids.  The NNT gene provides instructions for making an enzyme called nicotinamide nucleotide transhydrogenase. This enzyme is found embedded in the inner membrane of structures called mitochondria, which are the energy-producing centers of cells. This enzyme helps produce a substance called NADPH, which is involved in removing potentially toxic molecules called reactive oxygen species that can damage DNA, proteins, and cell membranes. NNT gene mutations impair the enzyme's ability to produce NADPH, leading to an increase in reactive oxygen species in adrenal gland tissues. Over time, these toxic molecules can impair the function of adrenal gland cells and lead to their death (apoptosis), diminishing the production of glucocorticoids.

Topic: familial glucocorticoid deficiency
Question: Is familial glucocorticoid deficiency inherited ?
Answer: This condition is inherited in an autosomal recessive pattern, which means both copies of the gene in each cell have mutations. The parents of an individual with an autosomal recessive condition each carry one copy of the mutated gene, but they typically do not show signs and symptoms of the condition.

Topic: Walker-Warburg syndrome
Question: What is (are) Walker-Warburg syndrome ?
Answer: Walker-Warburg syndrome is an inherited disorder that affects development of the muscles, brain, and eyes. It is the most severe of a group of genetic conditions known as congenital muscular dystrophies, which cause muscle weakness and wasting (atrophy) beginning very early in life. The signs and symptoms of Walker-Warburg syndrome are present at birth or in early infancy. Because of the severity of the problems caused by Walker-Warburg syndrome, most affected individuals do not survive past age 3.  Walker-Warburg syndrome affects the skeletal muscles, which are muscles the body uses for movement. Affected babies have weak muscle tone (hypotonia) and are sometimes described as "floppy." The muscle weakness worsens over time.  Walker-Warburg syndrome also affects the brain; individuals with this condition typically have a brain abnormality called cobblestone lissencephaly, in which the surface of the brain lacks the normal folds and grooves and instead develops a bumpy, irregular appearance (like that of cobblestones). They may also have a buildup of fluid in the brain (hydrocephalus) or abnormalities of other parts of the brain, including a region called the cerebellum and the part of the brain that connects to the spinal cord (the brainstem). These changes in the structure of the brain lead to significantly delayed development and intellectual disability. Some individuals with Walker-Warburg syndrome experience seizures.  Eye abnormalities are also characteristic of Walker-Warburg syndrome. These can include unusually small eyeballs (microphthalmia), enlarged eyeballs caused by increased pressure in the eyes (buphthalmos), clouding of the lenses of the eyes (cataracts), and problems with the nerve that relays visual information from the eyes to the brain (the optic nerve). These eye problems lead to vision impairment in affected individuals.

Topic: Walker-Warburg syndrome
Question: What are the genetic changes related to Walker-Warburg syndrome ?
Answer: Walker-Warburg syndrome can be caused by mutations in one of several genes, including POMT1, POMT2, ISPD, FKTN, FKRP, and LARGE. The proteins produced from these genes modify another protein called alpha ()-dystroglycan; this modification, called glycosylation, is required for -dystroglycan to function. The -dystroglycan protein helps anchor the structural framework inside each cell (cytoskeleton) to the lattice of proteins and other molecules outside the cell (extracellular matrix). In skeletal muscles, the anchoring function of -dystroglycan helps stabilize and protect muscle fibers. In the brain, it helps direct the movement (migration) of nerve cells (neurons) during early development.  Mutations in these genes prevent glycosylation of -dystroglycan, which disrupts its normal function. Without functional -dystroglycan to stabilize muscle cells, muscle fibers become damaged as they repeatedly contract and relax with use. The damaged fibers weaken and die over time, leading to progressive weakness of the skeletal muscles.  Defective -dystroglycan also affects the migration of neurons during the early development of the brain. Instead of stopping when they reach their intended destinations, some neurons migrate past the surface of the brain into the fluid-filled space that surrounds it. Researchers believe that this problem with neuronal migration causes cobblestone lissencephaly in children with Walker-Warburg syndrome. Less is known about the effects of the gene mutations in other parts of the body, including the eyes.  Mutations in the POMT1, POMT2, ISPD, FKTN, FKRP, and LARGE genes are found in only about half of individuals with Walker-Warburg syndrome. Other genes, some of which have not been identified, are likely involved in the development of this condition.  Because Walker-Warburg syndrome involves a malfunction of -dystroglycan, this condition is classified as a dystroglycanopathy.

Topic: Wolman disease
Question: What is (are) Wolman disease ?
Answer: Wolman disease is a rare inherited condition involving the breakdown and use of fats and cholesterol in the body (lipid metabolism). In affected individuals, harmful amounts of lipids accumulate in the spleen, liver, bone marrow, small intestine, small hormone-producing glands on top of each kidney (adrenal glands), and lymph nodes. In addition to fat deposits, calcium deposits in the adrenal glands are also seen.  Infants with Wolman disease are healthy and active at birth but soon develop signs and symptoms of the disorder. These may include an enlarged liver and spleen (hepatosplenomegaly), poor weight gain, low muscle tone, a yellow tint to the skin and the whites of the eyes (jaundice), vomiting, diarrhea, developmental delay, low amounts of iron in the blood (anemia), and poor absorption of nutrients from food. Children affected by this condition develop severe malnutrition and generally do not survive past early childhood.

Topic: Wolman disease
Question: What are the genetic changes related to Wolman disease ?
Answer: Mutations in the LIPA gene cause Wolman disease.  The LIPA gene provides instructions for producing an enzyme called lysosomal acid lipase. This enzyme is found in the lysosomes (compartments that digest and recycle materials in the cell), where it processes lipids such as cholesteryl esters and triglycerides so they can be used by the body.  Mutations in this gene lead to a shortage of lysosomal acid lipase and the accumulation of triglycerides, cholesteryl esters, and other kinds of fats within the cells and tissues of affected individuals. This accumulation as well as malnutrition caused by the body's inability to use lipids properly result in the signs and symptoms of Wolman disease.

Topic: glycogen storage disease type VI
Question: What is (are) glycogen storage disease type VI ?
Answer: Glycogen storage disease type VI (also known as GSDVI or Hers disease) is an inherited disorder caused by an inability to break down a complex sugar called glycogen in liver cells. A lack of glycogen breakdown interferes with the normal function of the liver.  The signs and symptoms of GSDVI typically begin in infancy to early childhood. The first sign is usually an enlarged liver (hepatomegaly). Affected individuals may also have low blood sugar (hypoglycemia) or a buildup of lactic acid in the body (lactic acidosis) during prolonged periods without food (fasting).  The signs and symptoms of GSDVI tend to improve with age; most adults with this condition do not have any related health problems.

Question: How many people are affected by glycogen storage disease type VI ?
Answer: The exact prevalence of GSDVI is unknown. At least 11 cases have been reported in the medical literature, although this condition is likely to be underdiagnosed because it can be difficult to detect in children with mild symptoms or adults with no symptoms. GSDVI is more common in the Old Older Mennonite population, with an estimated incidence of 1 in 1,000 individuals.

Topic: glycogen storage disease type VI
Question: What are the genetic changes related to glycogen storage disease type VI ?
Answer: Mutations in the PYGL gene cause GSDVI. The PYGL gene provides instructions for making an enzyme called liver glycogen phosphorylase. This enzyme is found only in liver cells, where it breaks down glycogen into a type of sugar called glucose-1-phosphate. Additional steps convert glucose-1-phosphate into glucose, a simple sugar that is the main energy source for most cells in the body.  PYGL gene mutations prevent liver glycogen phosphorylase from breaking down glycogen effectively. As a result, liver cells cannot use glycogen for energy. Since glycogen cannot be broken down, it accumulates within liver cells, causing these cells to become enlarged and dysfunctional.

Topic: guanidinoacetate methyltransferase deficiency
Question: What is (are) guanidinoacetate methyltransferase deficiency ?
Answer: Guanidinoacetate methyltransferase deficiency is an inherited disorder that primarily affects the brain and muscles. Without early treatment, people with this disorder have neurological problems that are usually severe. These problems include intellectual disability, speech development limited to a few words, and recurrent seizures (epilepsy). Affected individuals may also exhibit autistic behaviors that affect communication and social interaction or self-injurious behaviors such as head-banging. Other features of this disorder can include involuntary movements (extrapyramidal dysfunction) such as tremors or facial tics.  People with guanidinoacetate methyltransferase deficiency may have weak muscle tone and delayed development of motor skills such as sitting or walking. In severe cases they may lose previously acquired skills such as the ability to support their head or to sit unsupported.

Topic: guanidinoacetate methyltransferase deficiency
Question: What are the genetic changes related to guanidinoacetate methyltransferase deficiency ?
Answer: Mutations in the GAMT gene cause guanidinoacetate methyltransferase deficiency. The GAMT gene provides instructions for making the enzyme guanidinoacetate methyltransferase. This enzyme participates in the two-step production (synthesis) of the compound creatine from the protein building blocks (amino acids) glycine, arginine, and methionine. Specifically, guanidinoacetate methyltransferase controls the second step of this process. In this step, creatine is produced from another compound called guanidinoacetate. Creatine is needed for the body to store and use energy properly.  GAMT gene mutations impair the ability of the guanidinoacetate methyltransferase enzyme to participate in creatine synthesis, resulting in a shortage of creatine. The effects of guanidinoacetate methyltransferase deficiency are most severe in organs and tissues that require large amounts of energy, especially the brain.

Topic: enlarged parietal foramina
Question: What is (are) enlarged parietal foramina ?
Answer: Enlarged parietal foramina is an inherited condition of impaired skull development. It is characterized by enlarged openings (foramina) in the parietal bones, which are the two bones that form the top and sides of the skull. This condition is due to incomplete bone formation (ossification) within the parietal bones. The openings are symmetrical and circular in shape, ranging in size from a few millimeters to several centimeters wide. Parietal foramina are a normal feature of fetal development, but typically they close before the baby is born, usually by the fifth month of pregnancy. However, in people with this condition, the parietal foramina remain open throughout life.  The enlarged parietal foramina are soft to the touch due to the lack of bone at those areas of the skull. People with enlarged parietal foramina usually do not have any related health problems; however, scalp defects, seizures, and structural brain abnormalities have been noted in a small percentage of affected people. Pressure applied to the openings can lead to severe headaches, and individuals with this condition have an increased risk of brain damage or skull fractures if any trauma is experienced in the area of the openings.  There are two forms of enlarged parietal foramina, called type 1 and type 2, which differ in their genetic cause.

Topic: enlarged parietal foramina
Question: What are the genetic changes related to enlarged parietal foramina ?
Answer: Mutations in the ALX4 gene account for 60 percent of cases of enlarged parietal foramina and mutations in the MSX2 gene account for 40 percent of cases. These genes provide instructions for producing proteins called transcription factors, which are required for proper development throughout the body. Transcription factors attach (bind) to specific regions of DNA and help control the activity of particular genes. The ALX4 and MSX2 transcription factor proteins are involved in regulating genes that are needed in various cell processes in early development.  Mutations in either the ALX4 or MSX2 gene likely impair the ability of their respective transcription factors to bind to DNA. As a result, the regulation of multiple genes is altered, which disrupts a number of necessary cell functions. The processes that guide skull development seem to be particularly sensitive to changes in the activity of these transcription factors.  If the condition is caused by a mutation in the MSX2 gene, it is called enlarged parietal foramina type 1. Mutations in the ALX4 gene cause enlarged parietal foramina type 2. There appears to be no difference in the size of the openings between enlarged parietal foramina types 1 and 2.

Question: Is enlarged parietal foramina inherited ?
Answer: This condition is inherited in an autosomal dominant pattern, which means one copy of the altered gene in each cell is sufficient to cause the disorder. In most cases, an affected person has one parent with the condition.  However, in rare cases, people who inherit an altered gene do not have enlarged parietal foramina. (This situation is known as reduced penetrance.)

Topic: osteogenesis imperfecta
Question: What is (are) osteogenesis imperfecta ?
Answer: Osteogenesis imperfecta (OI) is a group of genetic disorders that mainly affect the bones. The term "osteogenesis imperfecta" means imperfect bone formation. People with this condition have bones that break easily, often from mild trauma or with no apparent cause. Multiple fractures are common, and in severe cases, can occur even before birth. Milder cases may involve only a few fractures over a person's lifetime.  There are at least eight recognized forms of osteogenesis imperfecta, designated type I through type VIII. The types can be distinguished by their signs and symptoms, although their characteristic features overlap. Type I is the mildest form of osteogenesis imperfecta and type II is the most severe; other types of this condition have signs and symptoms that fall somewhere between these two extremes. Increasingly, genetic factors are used to define the different forms of osteogenesis imperfecta.  The milder forms of osteogenesis imperfecta, including type I, are characterized by bone fractures during childhood and adolescence that often result from minor trauma. Fractures occur less frequently in adulthood. People with mild forms of the condition typically have a blue or grey tint to the part of the eye that is usually white (the sclera), and may develop hearing loss in adulthood. Affected individuals are usually of normal or near normal height.  Other types of osteogenesis imperfecta are more severe, causing frequent bone fractures that may begin before birth and result from little or no trauma. Additional features of these conditions can include blue sclerae, short stature, hearing loss, respiratory problems, and a disorder of tooth development called dentinogenesis imperfecta. The most severe forms of osteogenesis imperfecta, particularly type II, can include an abnormally small, fragile rib cage and underdeveloped lungs. Infants with these abnormalities have life-threatening problems with breathing and often die shortly after birth.
