Question: How many people are affected by fumarase deficiency ?
Answer: Fumarase deficiency is a very rare disorder. Approximately 100 affected individuals have been reported worldwide. Several were born in an isolated religious community in the southwestern United States.
Question: What are the genetic changes related to fumarase deficiency ?
Answer: The FH gene provides instructions for making an enzyme called fumarase (also known as fumarate hydratase). Fumarase participates in an important series of reactions known as the citric acid cycle or Krebs cycle, which allows cells to use oxygen and generate energy. Specifically, fumarase helps convert a molecule called fumarate to a molecule called malate. Mutations in the FH gene disrupt the enzyme's ability to help convert fumarate to malate, interfering with the function of this reaction in the citric acid cycle. Impairment of the process that generates energy for cells is particularly harmful to cells in the developing brain, and this impairment results in the signs and symptoms of fumarase deficiency.
Question: Is fumarase 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) phosphoglycerate dehydrogenase deficiency ?
Answer: Phosphoglycerate dehydrogenase deficiency is a condition characterized by an unusually small head size (microcephaly); impaired development of physical reactions, movements, and speech (psychomotor retardation); and recurrent seizures (epilepsy). Different types of phosphoglycerate dehydrogenase deficiency have been described; they are distinguished by their severity and the age at which symptoms first begin. Most affected individuals have the infantile form, which is the most severe form, and are affected from infancy. Symptoms of the juvenile and adult types appear later in life; these types are very rare. In phosphoglycerate dehydrogenase deficiency there is a progressive loss of brain cells leading to a loss of brain tissue (brain atrophy), specifically affecting the fatty tissue known as myelin that surrounds nerve cells (hypomyelination). Frequently, the tissue that connects the two halves of the brain (corpus callosum) is small and thin, and the fluid-filled cavities (ventricles) near the center of the brain are enlarged. Because development of the brain is disrupted, the head does not grow at the same rate as the body, so it appears that the head is getting smaller as the body grows (progressive microcephaly). Poor brain growth leads to an inability to achieve many developmental milestones such as sitting unsupported and speaking. Many affected infants also have difficulty feeding. The seizures in phosphoglycerate dehydrogenase deficiency can vary in type. Recurrent muscle contractions called infantile spasms are typical early in the disorder. Without early treatment, seizures may progress to tonic-clonic seizures, which involve a loss of consciousness, muscle rigidity, and convulsions; myoclonic seizures, which involve rapid, uncontrolled muscle jerks; or drop attacks, which are sudden episodes of weak muscle tone. Individuals with the infantile form of phosphoglycerate dehydrogenase deficiency develop many of the features described above. Individuals with the juvenile form typically have epilepsy as well as mild developmental delay and intellectual disability. Only one case of the adult form has been reported; signs and symptoms began in mid-adulthood and included mild intellectual disability; difficulty coordinating movements (ataxia); and numbness, tingling, and pain in the arms and legs (sensory neuropathy).
Question: How many people are affected by phosphoglycerate dehydrogenase deficiency ?
Answer: This condition is likely a rare disorder, but its prevalence is unknown. At least 15 cases have been described in the scientific literature.
Question: What are the genetic changes related to phosphoglycerate dehydrogenase deficiency ?
Answer: Mutations in the PHGDH gene cause phosphoglycerate dehydrogenase deficiency. The PHGDH gene provides instructions for making the parts (subunits) that make up the phosphoglycerate dehydrogenase enzyme. Four PHGDH subunits combine to form the enzyme. This enzyme is involved in the production of the protein building block (amino acid) serine. Specifically, the enzyme converts a substance called 3-phosphoglycerate to 3-phosphohydroxypyruvate in the first step in serine production. Serine is necessary for the development and function of the brain and spinal cord (central nervous system). Serine is a part of chemical messengers called neurotransmitters that transmit signals in the nervous system. Proteins that form cell membranes and myelin also contain serine. Serine can be obtained from the diet, but brain cells must produce their own serine because dietary serine cannot cross the protective barrier that allows only certain substances to pass between blood vessels and the brain (the blood-brain barrier). PHGDH gene mutations result in the production of an enzyme with decreased function. As a result, less 3-phosphoglycerate is converted into 3-phosphohydroxypyruvate than normal and serine production is stalled at the first step. The lack of serine likely prevents the production of proteins and neurotransmitters in the brain and impairs the formation of normal cells and myelin. These disruptions in normal brain development lead to the signs and symptoms of phosphoglycerate dehydrogenase deficiency.
Question: Is phosphoglycerate 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) sitosterolemia ?
Answer: Sitosterolemia is a condition in which fatty substances (lipids) from vegetable oils, nuts, and other plant-based foods accumulate in the blood and tissues. These lipids are called plant sterols (or phytosterols). Sitosterol is one of several plant sterols that accumulate in this disorder, with a blood level 30 to 100 times greater than normal. Cholesterol, a similar fatty substance found in animal products, is mildly to moderately elevated in many people with sitosterolemia. Cholesterol levels are particularly high in some affected children. Plant sterols are not produced by the body; they are taken in as components of foods. Signs and symptoms of sitosterolemia begin to appear early in life after foods containing plant sterols are introduced into the diet. An accumulation of fatty deposits on the artery walls (atherosclerosis) may occur by adolescence or early adulthood in people with sitosterolemia. The deposits narrow the arteries and can eventually block blood flow, increasing the chance of a heart attack, stroke, or sudden death. People with sitosterolemia typically develop small yellowish growths called xanthomas beginning in childhood. The xanthomas consist of accumulated lipids and may be located anywhere on or just under the skin, typically on the heels, knees, elbows, and buttocks. They may also occur in the bands that connect muscles to bones (tendons), including tendons of the hand and the tendon that connects the heel of the foot to the calf muscles (the Achilles tendon). Large xanthomas can cause pain, difficulty with movement, and cosmetic problems. Joint stiffness and pain resulting from plant sterol deposits may also occur in individuals with sitosterolemia. Less often, affected individuals have blood abnormalities. Occasionally the blood abnormalities are the only signs of the disorder. The red blood cells may be broken down (undergo hemolysis) prematurely, resulting in a shortage of red blood cells (anemia). This type of anemia is called hemolytic anemia. Affected individuals sometimes have abnormally shaped red blood cells called stomatocytes. In addition, the blood cells involved in clotting, called platelets or thrombocytes, may be abnormally large (macrothrombocytopenia).
Question: How many people are affected by sitosterolemia ?
Answer: Only 80 to 100 individuals with sitosterolemia have been described in the medical literature. However, researchers believe that this condition is likely underdiagnosed because mild cases often do not come to medical attention. Studies suggest that the prevalence may be at least 1 in 50,000 people.
Question: What are the genetic changes related to sitosterolemia ?
Answer: Sitosterolemia is caused by mutations in the ABCG5 or ABCG8 gene. These genes provide instructions for making the two halves of a protein called sterolin. This protein is involved in eliminating plant sterols, which cannot be used by human cells. Sterolin is a transporter protein, which is a type of protein that moves substances across cell membranes. It is found mostly in cells of the intestines and liver. After plant sterols in food are taken into intestinal cells, the sterolin transporters in these cells pump them back into the intestinal tract, decreasing absorption. Sterolin transporters in liver cells pump the plant sterols into a fluid called bile that is released into the intestine. From the intestine, the plant sterols are eliminated with the feces. This process removes most of the dietary plant sterols, and allows only about 5 percent of these substances to get into the bloodstream. Sterolin also helps regulate cholesterol levels in a similar fashion; normally about 50 percent of cholesterol in the diet is absorbed by the body. Mutations in the ABCG5 or ABCG8 gene that cause sitosterolemia result in a defective sterolin transporter and impair the elimination of plant sterols and, to a lesser degree, cholesterol from the body. These fatty substances build up in the arteries, skin, and other tissues, resulting in atherosclerosis, xanthomas, and the additional signs and symptoms of sitosterolemia. Excess plant sterols, such as sitosterol, in red blood cells likely make their cell membranes stiff and prone to rupture, leading to hemolytic anemia. Changes in the lipid composition of the membranes of red blood cells and platelets may account for the other blood abnormalities that sometimes occur in sitosterolemia.
Question: Is sitosterolemia 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) Menkes syndrome ?
Answer: Menkes syndrome is a disorder that affects copper levels in the body. It is characterized by sparse, kinky hair; failure to gain weight and grow at the expected rate (failure to thrive); and deterioration of the nervous system. Additional signs and symptoms include weak muscle tone (hypotonia), sagging facial features, seizures, developmental delay, and intellectual disability. Children with Menkes syndrome typically begin to develop symptoms during infancy and often do not live past age 3. Early treatment with copper may improve the prognosis in some affected individuals. In rare cases, symptoms begin later in childhood. Occipital horn syndrome (sometimes called X-linked cutis laxa) is a less severe form of Menkes syndrome that begins in early to middle childhood. It is characterized by wedge-shaped calcium deposits in a bone at the base of the skull (the occipital bone), coarse hair, and loose skin and joints.
Question: How many people are affected by Menkes syndrome ?
Answer: The incidence of Menkes syndrome and occipital horn syndrome is estimated to be 1 in 100,000 newborns.
Question: What are the genetic changes related to Menkes syndrome ?
Answer: Mutations in the ATP7A gene cause Menkes syndrome. The ATP7A gene provides instructions for making a protein that is important for regulating copper levels in the body. Copper is necessary for many cellular functions, but it is toxic when present in excessive amounts. Mutations in the ATP7A gene result in poor distribution of copper to the body's cells. Copper accumulates in some tissues, such as the small intestine and kidneys, while the brain and other tissues have unusually low levels of copper. The decreased supply of copper can reduce the activity of numerous copper-containing enzymes that are necessary for the structure and function of bone, skin, hair, blood vessels, and the nervous system. The signs and symptoms of Menkes syndrome and occipital horn syndrome are caused by the reduced activity of these copper-containing enzymes.
Question: Is Menkes syndrome inherited ?
Answer: Menkes syndrome is inherited in an X-linked recessive pattern. The gene associated with this condition is located on the X chromosome, which is one of the two sex chromosomes. In males (who have only one X chromosome), one altered copy of the gene in each cell is sufficient to cause the condition. In females (who have two X chromosomes), a mutation would have to occur in both copies of the gene to cause the disorder. Because it is unlikely that females will have two altered copies of this gene, males are affected by X-linked recessive disorders much more frequently than females. A characteristic of X-linked inheritance is that fathers cannot pass X-linked traits to their sons. In about one-third of cases, Menkes syndrome is caused by new mutations in the ATP7A gene. People with a new mutation do not have a history of the disorder in their family.

Question: What is (are) progressive osseous heteroplasia ?
Answer: Progressive osseous heteroplasia is a disorder in which bone forms within skin and muscle tissue. Bone that forms outside the skeleton is called heterotopic or ectopic bone. In progressive osseous heteroplasia, ectopic bone formation begins in the deep layers of the skin (dermis and subcutaneous fat) and gradually moves into other tissues such as skeletal muscle and tendons. The bony lesions within the skin may be painful and may develop into open sores (ulcers). Over time, joints can become involved, resulting in impaired mobility. Signs and symptoms of progressive osseous heteroplasia usually become noticeable during infancy. In some affected individuals, however, this may not occur until later in childhood or in early adulthood.
Question: How many people are affected by progressive osseous heteroplasia ?
Answer: Progressive osseous heteroplasia is a rare condition. Its exact incidence is unknown.
Question: What are the genetic changes related to progressive osseous heteroplasia ?
Answer: Progressive osseous heteroplasia is caused by a mutation in the GNAS gene. The GNAS gene provides instructions for making one part of a protein complex called a guanine nucleotide-binding protein, or a G protein. In a process called signal transduction, G proteins trigger a complex network of signaling pathways that ultimately influence many cell functions. The protein produced from the GNAS gene is believed to play a key role in signaling pathways that help regulate the development of bone (osteogenesis), preventing bony tissue from being produced outside the skeleton. The GNAS gene mutations that cause progressive osseous heteroplasia disrupt the function of the G protein and impair its ability to regulate osteogenesis. As a result, bony tissue grows outside the skeleton and causes the complications associated with this disorder.
Question: Is progressive osseous heteroplasia 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. People normally inherit one copy of each gene from their mother and one copy from their father. For most genes, both copies are active, or "turned on," in all cells. For a small subset of genes, however, only one of the two copies is active. For some of these genes, only the copy inherited from a person's father (the paternal copy) is active, while for other genes, only the copy inherited from a person's mother (the maternal copy) is active. These differences in gene activation based on the gene's parent of origin are caused by a phenomenon called genomic imprinting. The GNAS gene has a complex genomic imprinting pattern. In some cells of the body the maternal copy of the gene is active, while in others the paternal copy is active. Progressive osseous heteroplasia occurs when mutations affect the paternal copy of the gene.

Question: What is (are) task-specific focal dystonia ?
Answer: Task-specific focal dystonia is a movement disorder that interferes with the performance of particular tasks, such as writing, playing a musical instrument, or participating in a sport. Dystonias are a group of movement problems characterized by involuntary, sustained muscle contractions, tremors, and other uncontrolled movements. The term "focal" refers to a type of dystonia that affects a single part of the body, such as the hand or jaw. Researchers have described several forms of task-specific focal dystonia. The most common is writer's cramp, in which muscle cramps or spasms in the hand, wrist, or forearm interfere with holding a pen or pencil. Writer's cramp begins in the hand used for writing (the dominant hand) and is usually limited to that task, but with time it can spread to the other hand and affect other fine-motor activities such as shaving or typing. Musician's dystonia is a form of task-specific focal dystonia characterized by muscle cramps and spasms that occur while playing a musical instrument. This condition can affect amateur or professional musicians, and the location of the dystonia depends on the instrument. Some musicians (such as piano, guitar, and violin players) develop focal hand dystonia, which causes loss of fine-motor control in the hand and wrist muscles. This condition reduces finger coordination, speed, and endurance while playing. Musicians who play woodwind or brass instruments can develop what is known as embouchure dystonia. This condition causes muscle cramps or spasms involving the lips, tongue, or jaw, which prevents normal positioning of the mouth around the instrument's mouthpiece. Musician's dystonia often occurs only when playing a particular instrument. However, over time focal hand dystonia may impair other activities, and embouchure dystonia can worsen to affect eating and speech. Task-specific focal dystonia can affect people who play sports and engage in other occupations involving repetitive, highly practiced movements. For example, some golfers experience involuntary jerking of the wrists during putting, a condition known informally as "the yips." Cramps and spasms of the hand and arm muscles can also affect tennis players, billiards players, dart throwers, and other athletes. Additionally, task-specific dystonia has been reported in tailors, shoemakers, hair stylists, and people who frequently type or use a computer mouse. The abnormal movements associated with task-specific focal dystonia are usually painless, although they can cause anxiety when they interfere with musical performance and other activities. Severe cases can cause professional disability.
Question: How many people are affected by task-specific focal dystonia ?
Answer: Task-specific focal dystonia affects an estimated 7 to 69 per million people in the general population. Musician's dystonia that is severe enough to impact performance occurs in about 1 percent of musicians.
