Question: What are the genetic changes related to oculodentodigital dysplasia ?
Answer: Mutations in the GJA1 gene cause oculodentodigital dysplasia. The GJA1 gene provides instructions for making a protein called connexin43. This protein forms one part (a subunit) of channels called gap junctions, which allow direct communication between cells. Gap junctions formed by connexin43 proteins are found in many tissues throughout the body. GJA1 gene mutations result in abnormal connexin43 proteins. Channels formed with abnormal proteins are often permanently closed. Some mutations prevent connexin43 proteins from traveling to the cell surface where they are needed to form channels between cells. Impaired functioning of these channels disrupts cell-to-cell communication, which likely interferes with normal cell growth and cell specialization, processes that determine the shape and function of many different parts of the body. These developmental problems cause the signs and symptoms of oculodentodigital dysplasia.
Question: Is oculodentodigital dysplasia inherited ?
Answer: Most cases of oculodentodigital dysplasia are inherited in an autosomal dominant pattern, which means 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. Less commonly, oculodentodigital dysplasia can be 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. Fewer than ten cases of autosomal recessive oculodentodigital dysplasia have been reported.

Question: What is (are) succinic semialdehyde dehydrogenase deficiency ?
Answer: Succinic semialdehyde dehydrogenase deficiency is a disorder that can cause a variety of neurological problems. People with this condition typically have developmental delay, especially involving speech development; intellectual disability; and decreased muscle tone (hypotonia) soon after birth. About half of those affected experience seizures, difficulty coordinating movements (ataxia), decreased reflexes (hyporeflexia), and behavioral problems. The most common behavioral problems associated with this condition are sleep disturbances, hyperactivity, difficulty maintaining attention, and anxiety. Less frequently, affected individuals may have increased aggression, hallucinations, obsessive-compulsive disorder (OCD), and self-injurious behavior, including biting and head banging. People with this condition can also have problems controlling eye movements. Less common features of succinic semialdehyde dehydrogenase deficiency include uncontrollable movements of the limbs (choreoathetosis), involuntary tensing of the muscles (dystonia), muscle twitches (myoclonus), and a progressive worsening of ataxia.
Question: How many people are affected by succinic semialdehyde dehydrogenase deficiency ?
Answer: Approximately 350 people with succinic semialdehyde dehydrogenase deficiency have been reported worldwide.
Question: What are the genetic changes related to succinic semialdehyde dehydrogenase deficiency ?
Answer: Mutations in the ALDH5A1 gene cause succinic semialdehyde dehydrogenase deficiency. The ALDH5A1 gene provides instructions for producing the succinic semialdehyde dehydrogenase enzyme. This enzyme is involved in the breakdown of a chemical that transmits signals in the brain (neurotransmitter) called gamma-amino butyric acid (GABA). The primary role of GABA is to prevent the brain from being overloaded with too many signals. A shortage (deficiency) of succinic semialdehyde dehydrogenase leads to an increase in the amount of GABA and a related molecule called gamma-hydroxybutyrate (GHB) in the body, particularly the brain and spinal cord (central nervous system). It is unclear how an increase in GABA and GHB causes developmental delay, seizures, and other signs and symptoms of succinic semialdehyde dehydrogenase deficiency.
Question: Is succinic semialdehyde dehydrogenase 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.

Question: What is (are) Muenke syndrome ?
Answer: Muenke syndrome is a condition characterized by the premature closure of certain bones of the skull (craniosynostosis) during development, which affects the shape of the head and face. Many people with this disorder have a premature fusion of skull bones along the coronal suture, the growth line which goes over the head from ear to ear. Other parts of the skull may be malformed as well. These changes can result in an abnormally shaped head, wide-set eyes, and flattened cheekbones. About 5 percent of affected individuals have an enlarged head (macrocephaly). People with Muenke syndrome may also have mild abnormalities of the hands or feet, and hearing loss has been observed in some cases. Most people with this condition have normal intellect, but developmental delay and learning disabilities are possible. The signs and symptoms of Muenke syndrome vary among affected people, and some findings overlap with those seen in other craniosynostosis syndromes. Between 6 percent and 7 percent of people with the gene mutation associated with Muenke syndrome do not have any of the characteristic features of the disorder.
Question: How many people are affected by Muenke syndrome ?
Answer: Muenke syndrome occurs in about 1 in 30,000 newborns. This condition accounts for an estimated 8 percent of all cases of craniosynostosis.
Question: What are the genetic changes related to Muenke syndrome ?
Answer: Mutations in the FGFR3 gene cause Muenke syndrome. The FGFR3 gene provides instructions for making a protein that is involved in the development and maintenance of bone and brain tissue. A single mutation in the FGFR3 gene is responsible for Muenke syndrome. This mutation causes the FGFR3 protein to be overly active, which interferes with normal bone growth and allows the bones of the skull to fuse before they should.
Question: Is Muenke syndrome 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.

Question: What is (are) autoimmune Addison disease ?
Answer: Autoimmune Addison disease affects the function of the adrenal glands, which are small hormone-producing glands located on top of each kidney. It is classified as an autoimmune disorder because it results from a malfunctioning immune system that attacks the adrenal glands. As a result, the production of several hormones is disrupted, which affects many body systems. The signs and symptoms of autoimmune Addison disease can begin at any time, although they most commonly begin between ages 30 and 50. Common features of this condition include extreme tiredness (fatigue), nausea, decreased appetite, and weight loss. In addition, many affected individuals have low blood pressure (hypotension), which can lead to dizziness when standing up quickly; muscle cramps; and a craving for salty foods. A characteristic feature of autoimmune Addison disease is abnormally dark areas of skin (hyperpigmentation), especially in regions that experience a lot of friction, such as the armpits, elbows, knuckles, and palm creases. The lips and the inside lining of the mouth can also be unusually dark. Because of an imbalance of hormones involved in development of sexual characteristics, women with this condition may lose their underarm and pubic hair. Other signs and symptoms of autoimmune Addison disease include low levels of sugar (hypoglycemia) and sodium (hyponatremia) and high levels of potassium (hyperkalemia) in the blood. Affected individuals may also have a shortage of red blood cells (anemia) and an increase in the number of white blood cells (lymphocytosis), particularly those known as eosinophils (eosinophilia). Autoimmune Addison disease can lead to a life-threatening adrenal crisis, characterized by vomiting, abdominal pain, back or leg cramps, and severe hypotension leading to shock. The adrenal crisis is often triggered by a stressor, such as surgery, trauma, or infection. Individuals with autoimmune Addison disease or their family members often have another autoimmune disorder, most commonly autoimmune thyroid disease or type 1 diabetes.
Question: How many people are affected by autoimmune Addison disease ?
Answer: Addison disease affects approximately 11 to 14 in 100,000 people of European descent. The autoimmune form of the disorder is the most common form in developed countries, accounting for up to 90 percent of cases.
Question: What are the genetic changes related to autoimmune Addison disease ?
Answer: The cause of autoimmune Addison disease is complex and not completely understood. A combination of environmental and genetic factors plays a role in the disorder, and changes in multiple genes are thought to affect the risk of developing the condition. The genes that have been associated with autoimmune Addison disease participate in the body's immune response. The most commonly associated genes belong to a family of genes called the human leukocyte antigen (HLA) complex. The HLA complex helps the immune system distinguish the body's own proteins from proteins made by foreign invaders (such as viruses and bacteria). Each HLA gene has many different normal variations, allowing each person's immune system to react to a wide range of foreign proteins. The most well-known risk factor for autoimmune Addison disease is a variant of the HLA-DRB1 gene called HLA-DRB1*04:04. This and other disease-associated HLA gene variants likely contribute to an inappropriate immune response that leads to autoimmune Addison disease, although the mechanism is unknown. Normally, the immune system responds only to proteins made by foreign invaders, not to the body's own proteins. In autoimmune Addison disease, however, an immune response is triggered by a normal adrenal gland protein, typically a protein called 21-hydroxylase. This protein plays a key role in producing certain hormones in the adrenal glands. The prolonged immune attack triggered by 21-hydroxylase damages the adrenal glands (specifically the outer layers of the glands known, collectively, as the adrenal cortex), preventing hormone production. A shortage of adrenal hormones (adrenal insufficiency) disrupts several normal functions in the body, leading to hypoglycemia, hyponatremia, hypotension, muscle cramps, skin hyperpigmentation and other features of autoimmune Addison disease. Rarely, Addison disease is not caused by an autoimmune reaction. Other causes include infections that damage the adrenal glands, such as tuberculosis, or tumors in the adrenal glands. Addison disease can also be one of several features of other genetic conditions, including X-linked adrenoleukodystrophy and autoimmune polyglandular syndrome, type 1, which are caused by mutations in other genes.
Question: Is autoimmune Addison disease inherited ?
Answer: A predisposition to develop autoimmune Addison disease is passed through generations in families, but the inheritance pattern is unknown.

Question: What is (are) peroxisomal acyl-CoA oxidase deficiency ?
Answer: Peroxisomal acyl-CoA oxidase deficiency is a disorder that causes deterioration of nervous system functions (neurodegeneration) beginning in infancy. Newborns with peroxisomal acyl-CoA oxidase deficiency have weak muscle tone (hypotonia) and seizures. They may have unusual facial features, including widely spaced eyes (hypertelorism), a low nasal bridge, and low-set ears. Extra fingers or toes (polydactyly) or an enlarged liver (hepatomegaly) also occur in some affected individuals. Most babies with peroxisomal acyl-CoA oxidase deficiency learn to walk and begin speaking, but they experience a gradual loss of these skills (developmental regression), usually beginning between the ages of 1 and 3. As the condition gets worse, affected children develop exaggerated reflexes (hyperreflexia), increased muscle tone (hypertonia), more severe and recurrent seizures (epilepsy), and loss of vision and hearing. Most children with peroxisomal acyl-CoA oxidase deficiency do not survive past early childhood.
Question: How many people are affected by peroxisomal acyl-CoA oxidase deficiency ?
Answer: Peroxisomal acyl-CoA oxidase deficiency is a rare disorder. Its prevalence is unknown. Only a few dozen cases have been described in the medical literature.
Question: What are the genetic changes related to peroxisomal acyl-CoA oxidase deficiency ?
Answer: Peroxisomal acyl-CoA oxidase deficiency is caused by mutations in the ACOX1 gene, which provides instructions for making an enzyme called peroxisomal straight-chain acyl-CoA oxidase. This enzyme is found in sac-like cell structures (organelles) called peroxisomes, which contain a variety of enzymes that break down many different substances. The peroxisomal straight-chain acyl-CoA oxidase enzyme plays a role in the breakdown of certain fat molecules called very long-chain fatty acids (VLCFAs). Specifically, it is involved in the first step of a process called the peroxisomal fatty acid beta-oxidation pathway. This process shortens the VLCFA molecules by two carbon atoms at a time until the VLCFAs are converted to a molecule called acetyl-CoA, which is transported out of the peroxisomes for reuse by the cell. ACOX1 gene mutations prevent the peroxisomal straight-chain acyl-CoA oxidase enzyme from breaking down VLCFAs efficiently. As a result, these fatty acids accumulate in the body. It is unclear exactly how VLCFA accumulation leads to the specific features of peroxisomal acyl-CoA oxidase deficiency. However, researchers suggest that the abnormal fatty acid accumulation triggers inflammation in the nervous system that leads to the breakdown of myelin, which is the covering that protects nerves and promotes the efficient transmission of nerve impulses. Destruction of myelin leads to a loss of myelin-containing tissue (white matter) in the brain and spinal cord; loss of white matter is described as leukodystrophy. Leukodystrophy is likely involved in the development of the neurological abnormalities that occur in peroxisomal acyl-CoA oxidase deficiency.
Question: Is peroxisomal acyl-CoA oxidase 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.

Question: What is (are) familial dilated cardiomyopathy ?
Answer: Familial dilated cardiomyopathy is a genetic form of heart disease. It occurs when heart (cardiac) muscle becomes stretched out in at least one chamber of the heart, causing the open area of the chamber to become enlarged (dilated). As a result, the heart is unable to pump blood as efficiently as usual. Eventually, all four chambers of the heart become dilated as the cardiac muscle tries to increase the amount of blood being pumped through the heart. However, as the cardiac muscle becomes increasingly thin and weakened, it is less able to pump blood. Over time, this condition results in heart failure. It usually takes many years for symptoms of familial dilated cardiomyopathy to appear. They typically begin in mid-adulthood, but can occur at any time from infancy to late adulthood. Signs and symptoms of familial dilated cardiomyopathy can include an irregular heartbeat (arrhythmia), shortness of breath (dyspnea), extreme tiredness (fatigue), fainting episodes (syncope), and swelling of the legs and feet. In some cases, the first sign of the disorder is sudden cardiac death. The severity of the condition varies among affected individuals, even in members of the same family.
Question: How many people are affected by familial dilated cardiomyopathy ?
Answer: It is estimated that 750,000 people in the United States have dilated cardiomyopathy; roughly half of these cases are familial.
Question: What are the genetic changes related to familial dilated cardiomyopathy ?
Answer: Mutations in more than 30 genes have been found to cause familial dilated cardiomyopathy. These genes provide instructions for making proteins that are found in cardiac muscle cells called cardiomyocytes. Many of these proteins play important roles in the contraction of the cardiac muscle through their association with cell structures called sarcomeres. Sarcomeres are the basic units of muscle contraction; they are made of proteins that generate the mechanical force needed for muscles to contract. Many other proteins associated with familial dilated cardiomyopathy make up the structural framework (the cytoskeleton) of cardiomyocytes. The remaining proteins play various roles within cardiomyocytes to ensure their proper functioning. Mutations in one gene, TTN, account for approximately 20 percent of cases of familial dilated cardiomyopathy. The TTN gene provides instructions for making a protein called titin, which is found in the sarcomeres of many types of muscle cells, including cardiomyocytes. Titin has several functions within sarcomeres. One of its most important jobs is to provide structure, flexibility, and stability to these cell structures. Titin also plays a role in chemical signaling and in assembling new sarcomeres. The TTN gene mutations that cause familial dilated cardiomyopathy result in the production of an abnormally short titin protein. It is unclear how the altered protein causes familial dilated cardiomyopathy, but it is likely that it impairs sarcomere function and disrupts chemical signaling. It is unclear how mutations in the other genes cause familial dilated cardiomyopathy. It is likely that the changes impair cardiomyocyte function and reduce the ability of these cells to contract, weakening and thinning cardiac muscle. People with familial dilated cardiomyopathy often do not have an identified mutation in any of the known associated genes. The cause of the condition in these individuals is unknown. Familial dilated cardiomyopathy is described as nonsyndromic or isolated because it typically affects only the heart. However, dilated cardiomyopathy can also occur as part of syndromes that affect other organs and tissues in the body. These forms of the condition are described as syndromic and are caused by mutations in other genes. Additionally, there are many nongenetic causes of dilated cardiomyopathy, including viral infection and chronic alcohol abuse.
Question: Is familial dilated cardiomyopathy inherited ?
Answer: Familial dilated cardiomyopathy has different inheritance patterns depending on the gene involved. In 80 to 90 percent of cases, familial dilated cardiomyopathy 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 inherits the mutation from one affected parent. However, some people who inherit the altered gene never develop features of familial dilated cardiomyopathy. (This situation is known as reduced penetrance.) Other cases result from new mutations in the gene and occur in people with no history of the disorder in their family. In rare instances, 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. In other rare cases, this condition is inherited in an X-linked pattern. In these cases, the gene associated with this condition is located on the X chromosome, which is one of the two sex chromosomes. In females (who have two X chromosomes), a mutation in one of the two copies of the gene in each cell increases the risk of developing heart disease, but females with such a mutation may not develop familial dilated cardiomyopathy. In males (who have only one X chromosome), a mutation in the only copy of the gene in each cell causes familial dilated cardiomyopathy. A characteristic of X-linked inheritance is that fathers cannot pass X-linked traits to their sons.
