Topic: type A insulin resistance syndrome
Question: What are the genetic changes related to type A insulin resistance syndrome ?
Answer: Type A insulin resistance syndrome results from mutations in the INSR gene. This gene provides instructions for making a protein called an insulin receptor, which is found in many types of cells. Insulin receptors are embedded in the outer membrane surrounding the cell, where they attach (bind) to insulin circulating in the bloodstream. This binding triggers signaling pathways that influence many cell functions.  Most of the INSR gene mutations that cause type A insulin resistance syndrome lead to the production of a faulty insulin receptor that cannot transmit signals properly. Although insulin is present in the bloodstream, the defective receptors make it less able to exert its effects on cells and tissues. This severe resistance to the effects of insulin impairs blood sugar regulation and leads to diabetes mellitus. In females with type A insulin resistance syndrome, excess insulin in the bloodstream interacts with hormonal factors during adolescence to cause abnormalities of the menstrual cycle, ovarian cysts, and other features of the disorder.  This condition is designated as type A to distinguish it from type B insulin resistance syndrome. Although the two disorders have similar signs and symptoms, type B is not caused by INSR gene mutations; instead, it results from an abnormality of the immune system that blocks insulin receptor function.

Question: Is type A insulin resistance syndrome inherited ?
Answer: Type A insulin resistance syndrome can have either an autosomal dominant or, less commonly, an autosomal recessive pattern of inheritance.  In autosomal dominant inheritance, one copy of the altered gene in each cell is sufficient to cause the disorder. In some cases, an affected person inherits the mutation from one affected parent. Other cases result from new mutations in the gene and occur in people with no history of the disorder in their family.  In autosomal recessive inheritance, 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: Gillespie syndrome
Question: What is (are) Gillespie syndrome ?
Answer: Gillespie syndrome is a disorder that involves eye abnormalities, problems with balance and coordinating movements (ataxia), and mild to moderate intellectual disability.  Gillespie syndrome is characterized by aniridia, which is the absence of the colored part of the eye (the iris). In most affected individuals, only part of the iris is missing (partial aniridia) in both eyes, but in some affected individuals, partial aniridia affects only one eye, or the entire iris is missing (complete aniridia) in one or both eyes. The absence of all or part of the iris can cause blurry vision (reduced visual acuity) and increased sensitivity to light (photophobia). Rapid, involuntary eye movements (nystagmus) can also occur in Gillespie syndrome.  The balance and movement problems in Gillespie syndrome result from underdevelopment (hypoplasia) of a part of the brain called the cerebellum. This abnormality can cause delayed development of motor skills such as walking. In addition, difficulty controlling the muscles in the mouth can lead to delayed speech development. The difficulties with coordination generally become noticeable in early childhood when the individual is learning these skills. People with Gillespie syndrome usually continue to have an unsteady gait and speech problems. However, the problems do not get worse over time, and in some cases they improve slightly.  Other features of Gillespie syndrome can include abnormalities in the bones of the spine (vertebrae) and malformations of the heart.

Question: What are the genetic changes related to Gillespie syndrome ?
Answer: Gillespie syndrome can be caused by mutations in the PAX6 gene. The PAX6 gene provides instructions for making a protein that is involved in early development, including the development of the eyes and brain. The PAX6 protein attaches (binds) to specific regions of DNA and regulates the activity of other genes. On the basis of this role, the PAX6 protein is called a transcription factor.  Mutations in the PAX6 gene result in the absence of the PAX6 protein or production of a nonfunctional PAX6 protein that is unable to bind to DNA and regulate the activity of other genes. This lack of functional protein disrupts embryonic development, especially the development of the eyes and brain, leading to the signs and symptoms of Gillespie syndrome.  Most people with Gillespie syndrome do not have mutations in the PAX6 gene. In these affected individuals, the cause of the disorder is unknown.

Question: Is Gillespie syndrome inherited ?
Answer: In some cases, including those in which Gillespie syndrome is caused by PAX6 gene mutations, the condition occurs in an autosomal dominant pattern, which means one copy of the altered gene in each cell is sufficient to cause the disorder. Some affected individuals inherit the mutation from one affected parent. Other cases result from new mutations in the gene and occur in people with no history of the disorder in their family.  Gillespie syndrome can also be inherited in an autosomal recessive pattern, which means both copies of a gene in each cell have mutations. The gene or genes involved in these cases are unknown. 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: Aicardi-Goutieres syndrome
Question: What is (are) Aicardi-Goutieres syndrome ?
Answer: Aicardi-Goutieres syndrome is a disorder that mainly affects the brain, the immune system, and the skin.  Most newborns with Aicardi-Goutieres syndrome do not show any signs or symptoms of the disorder at birth. However, about 20 percent are born with a combination of features that include an enlarged liver and spleen (hepatosplenomegaly), elevated blood levels of liver enzymes, a decrease in blood platelets (thrombocytopenia), and abnormal neurological responses. While this combination of signs and symptoms is typically associated with the immune system's response to congenital viral infection, no actual infection is found in these infants. For this reason, Aicardi-Goutieres syndrome is sometimes referred to as a "mimic of congenital infection."  Within the first year of life most individuals with Aicardi-Goutieres syndrome experience an episode of severe brain dysfunction (encephalopathy), typically lasting for several months. During this phase of the disorder, affected babies are usually extremely irritable and do not feed well. They may develop intermittent fevers in the absence of infection (sterile pyrexias) and may have seizures. They stop developing new skills and begin losing skills they had already acquired (developmental regression). Growth of the brain and skull slows down, resulting in an abnormally small head size (microcephaly). In this phase of the disorder, white blood cells and molecules associated with inflammation can be detected in the cerebrospinal fluid, which is the fluid that surrounds the brain and spinal cord (central nervous system). These abnormal findings are consistent with inflammation and tissue damage in the central nervous system.  The encephalopathic phase of Aicardi-Goutieres syndrome leaves behind permanent neurological damage that is usually severe. Medical imaging reveals deterioration of white matter in the brain (leukodystrophy). White matter consists of nerve fibers covered by myelin, which is a substance that insulates and protects nerves. Affected individuals also have abnormal deposits of calcium (calcification) in the brain.  Most people with Aicardi-Goutieres syndrome have profound intellectual disability. They also have significant neuromuscular problems including muscle stiffness (spasticity); involuntary tensing of various muscles (dystonia), especially those in the arms; and weak muscle tone (hypotonia) in the trunk.  About 40 percent of people with Aicardi-Goutieres syndrome have painful, itchy skin lesions, usually on the fingers, toes, and ears. These puffy, red lesions, which are called chilblains, are caused by inflammation of small blood vessels. They may be brought on or made worse by exposure to cold. Vision problems, joint stiffness, and mouth ulcers may also occur in this disorder.  As a result of the severe neurological problems usually associated with Aicardi-Goutieres syndrome, most people with this disorder do not survive past childhood. However, some affected individuals who have later onset and milder neurological problems may live into adulthood.

Topic: Aicardi-Goutieres syndrome
Question: What are the genetic changes related to Aicardi-Goutieres syndrome ?
Answer: Mutations in the TREX1, RNASEH2A, RNASEH2B, RNASEH2C, and SAMHD1 genes have been identified in people with Aicardi-Goutieres syndrome.  The TREX1, RNASEH2A, RNASEH2B, and RNASEH2C genes provide instructions for making nucleases, which are enzymes that help break up molecules of DNA and its chemical cousin RNA. Mutations in any of these genes are believed to result in an absent or dysfunctional nuclease enzyme. Researchers suggest that absent or impaired enzyme function may result in the accumulation of unneeded DNA and RNA in cells. These DNA and RNA molecules or fragments may be generated during the first stage of protein production (transcription), copying (replication) of cells' genetic material in preparation for cell division, DNA repair, cell death, and other processes. The unneeded DNA and RNA may be mistaken by cells for that of viral invaders, triggering immune system reactions that result in encephalopathy, skin lesions, and other signs and symptoms of Aicardi-Goutieres syndrome.  The SAMHD1 gene provides instructions for making a protein whose function is not well understood; however, it is believed to be involved in the immune system and the inflammatory process. Mutations in this gene likely result in a protein that does not function properly, resulting in immune system abnormalities, inflammatory damage to the brain and skin, and other characteristics of Aicardi-Goutieres syndrome.

Topic: ALG6-congenital disorder of glycosylation
Question: What is (are) ALG6-congenital disorder of glycosylation ?
Answer: ALG6-congenital disorder of glycosylation (ALG6-CDG, also known as congenital disorder of glycosylation type Ic) is an inherited condition that affects many parts of the body. The signs and symptoms of ALG6-CDG vary widely among people with the condition.  Individuals with ALG6-CDG typically develop signs and symptoms of the condition during infancy. They may have difficulty gaining weight and growing at the expected rate (failure to thrive). Affected infants often have weak muscle tone (hypotonia) and developmental delay.  People with ALG6-CDG may have seizures, problems with coordination and balance (ataxia), or stroke-like episodes that involve an extreme lack of energy (lethargy) and temporary paralysis. They may also develop blood clotting disorders. Some individuals with ALG6-CDG have eye abnormalities including eyes that do not look in the same direction (strabismus) and an eye disorder called retinitis pigmentosa, which causes vision loss. Females with ALG6-CDG have hypergonadotropic hypogonadism, which affects the production of hormones that direct sexual development. As a result, most females with ALG6-CDG do not go through puberty.

Topic: ALG6-congenital disorder of glycosylation
Question: What are the genetic changes related to ALG6-congenital disorder of glycosylation ?
Answer: ALG6-CDG is caused by mutations in the ALG6 gene. This gene provides instructions for making an enzyme that is involved in a process called glycosylation. Glycosylation is the process by which sugar molecules (monosaccharides) and complex chains of sugar molecules (oligosaccharides) are added to proteins and fats. Glycosylation modifies proteins and fats so they can perform a wider variety of functions. The enzyme produced from the ALG6 gene transfers a simple sugar called glucose to the growing oligosaccharide. Once the correct number of sugar molecules are linked together, the oligosaccharide is attached to a protein or fat.  ALG6 gene mutations lead to the production of an abnormal enzyme with reduced or no activity. Without a properly functioning enzyme, glycosylation cannot proceed normally, and oligosaccharides are incomplete. As a result, glycosylation is reduced or absent. The wide variety of signs and symptoms in ALG6-CDG are likely due to impaired glycosylation of proteins and fats that are needed for normal function in many organs and tissues, including the brain, eyes, liver, and hormone-producing (endocrine) system.

Topic: Gilbert syndrome
Question: What is (are) Gilbert syndrome ?
Answer: Gilbert syndrome is a relatively mild condition characterized by periods of elevated levels of a toxic substance called bilirubin in the blood (hyperbilirubinemia). Bilirubin, which has an orange-yellow tint, is produced when red blood cells are broken down. This substance is removed from the body only after it undergoes a chemical reaction in the liver, which converts the toxic form of bilirubin (unconjugated bilirubin) to a nontoxic form called conjugated bilirubin. People with Gilbert syndrome have a buildup of unconjugated bilirubin in their blood (unconjugated hyperbilirubinemia). In affected individuals, bilirubin levels fluctuate and very rarely increase to levels that cause jaundice, which is yellowing of the skin and whites of the eyes.  Gilbert syndrome is usually recognized in adolescence. If people with this condition have episodes of hyperbilirubinemia, these episodes are generally mild and typically occur when the body is under stress, for instance because of dehydration, prolonged periods without food (fasting), illness, vigorous exercise, or menstruation. Some people with Gilbert syndrome also experience abdominal discomfort or tiredness. However, approximately 30 percent of people with Gilbert syndrome have no signs or symptoms of the condition and are discovered only when routine blood tests reveal elevated unconjugated bilirubin levels.

Topic: Gilbert syndrome
Question: What are the genetic changes related to Gilbert syndrome ?
Answer: Changes in the UGT1A1 gene cause Gilbert syndrome. This gene provides instructions for making the bilirubin uridine diphosphate glucuronosyltransferase (bilirubin-UGT) enzyme, which is found primarily in liver cells and is necessary for the removal of bilirubin from the body.  The bilirubin-UGT enzyme performs a chemical reaction called glucuronidation. During this reaction, the enzyme transfers a compound called glucuronic acid to unconjugated bilirubin, converting it to conjugated bilirubin. Glucuronidation makes bilirubin dissolvable in water so that it can be removed from the body.  Gilbert syndrome occurs worldwide, but some mutations occur more often in particular populations. In many populations, the most common genetic change that causes Gilbert syndrome (known as UGT1A1*28) occurs in an area near the UGT1A1 gene called the promoter region, which controls the production of the bilirubin-UGT enzyme. This genetic change impairs enzyme production. However, this change is uncommon in Asian populations, and affected Asians often have a mutation that changes a single protein building block (amino acid) in the bilirubin-UGT enzyme. This type of mutation, known as a missense mutation, results in reduced enzyme function.  People with Gilbert syndrome have approximately 30 percent of normal bilirubin-UGT enzyme function. As a result, unconjugated bilirubin is not glucuronidated quickly enough. This toxic substance then builds up in the body, causing mild hyperbilirubinemia.  Not everyone with the genetic changes that cause Gilbert syndrome develops hyperbilirubinemia, indicating that additional factors, such as conditions that further hinder the glucuronidation process, may be necessary for development of the condition. For example, red blood cells may break down too easily, releasing excess amounts of bilirubin that the impaired enzyme cannot keep up with. Alternatively, movement of bilirubin into the liver, where it would be glucuronidated, may be impaired. These other factors may be due to changes in other genes.

Topic: Gilbert syndrome
Question: Is Gilbert syndrome inherited ?
Answer: Gilbert syndrome can have different inheritance patterns. When the condition is caused by the UGT1A1*28 change in the promoter region of the UGT1A1 gene, it is inherited in an autosomal recessive pattern, which means both copies of the gene in each cell have the mutation. 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.  When the condition is caused by a missense mutation in the UGT1A1 gene, it is inherited in an autosomal dominant pattern, which means one copy of the altered gene in each cell is sufficient to cause the disorder. A more severe condition known as Crigler-Najjar syndrome occurs when both copies of the UGT1A1 gene have mutations.
