Question: What are the genetic changes related to cytogenetically normal acute myeloid leukemia ?
Answer: CN-AML is classified as "cytogenetically normal" based on the type of genetic changes involved in its development. Cytogenetically normal refers to the fact that this form of acute myeloid leukemia is not associated with large chromosomal abnormalities. About half of people with acute myeloid leukemia have this form of the condition; the other half have genetic changes that alter large regions of certain chromosomes. These changes can be identified by a test known as cytogenetic analysis. CN-AML is associated with smaller genetic changes that cannot be seen by cytogenetic analysis. Mutations in a large number of genes have been found in people with CN-AML; the most commonly affected genes are NPM1, FLT3, DNMT3A, CEBPA, IDH1, and IDH2. The proteins produced from these genes have different functions in the cell. Most are involved in regulating processes such as the growth and division (proliferation), maturation (differentiation), or survival of cells. For example, the protein produced from the FLT3 gene stimulates the proliferation and survival of cells. The proteins produced from the CEBPA and DNMT3A genes regulate gene activity and help to control when cells divide and how they mature. The NPM1 gene provides instructions for a protein that is likely involved in the regulation of cell growth and division. Mutations in any of these genes can disrupt one or more of these processes in hematopoietic stem cells and lead to overproduction of abnormal, immature white blood cells, which is characteristic of CN-AML. Although the proteins produced from two other genes involved in CN-AML, IDH1 and IDH2, are not normally involved in proliferation, differentiation, or survival of cells, mutations in these genes lead to the production of proteins with a new function. These changes result in impaired differentiation of hematopoietic stem cells, which leads to CN-AML. CN-AML is a complex condition influenced by several genetic and environmental factors. Typically, mutations in more than one gene are involved. For example, people with an NPM1 gene mutation frequently also have a mutation in the FLT3 gene, both of which are likely involved in the cancer's development. In addition, environmental factors such as smoking or exposure to radiation increase an individual's risk of developing acute myeloid leukemia.
Question: Is cytogenetically normal acute myeloid leukemia inherited ?
Answer: CN-AML is not usually inherited but arises from genetic changes in the body's cells that occur after conception. Rarely, an inherited mutation in the CEBPA gene causes acute myeloid leukemia. In these cases, the condition follows an autosomal dominant pattern of inheritance, which means that one copy of the altered CEBPA gene in each cell is sufficient to cause the disorder. These cases of CN-AML are referred to as familial acute myeloid leukemia with mutated CEBPA.

Question: What is (are) prothrombin deficiency ?
Answer: Prothrombin deficiency is a bleeding disorder that slows the blood clotting process. People with this condition often experience prolonged bleeding following an injury, surgery, or having a tooth pulled. In severe cases of prothrombin deficiency, heavy bleeding occurs after minor trauma or even in the absence of injury (spontaneous bleeding). Women with prothrombin deficiency can have prolonged and sometimes abnormally heavy menstrual bleeding. Serious complications can result from bleeding into the joints, muscles, brain, or other internal organs. Milder forms of prothrombin deficiency do not involve spontaneous bleeding, and the condition may only become apparent following surgery or a serious injury.
Question: How many people are affected by prothrombin deficiency ?
Answer: Prothrombin deficiency is very rare; it is estimated to affect 1 in 2 million people in the general population.
Question: What are the genetic changes related to prothrombin deficiency ?
Answer: Mutations in the F2 gene cause prothrombin deficiency. The F2 gene provides instructions for making the prothrombin protein (also called coagulation factor II), which plays a critical role in the formation of blood clots in response to injury. Prothrombin is the precursor to thrombin, a protein that initiates a series of chemical reactions to form a blood clot. After an injury, clots protect the body by sealing off damaged blood vessels and preventing further blood loss. F2 gene mutations reduce the production of prothrombin in cells, which prevents clots from forming properly in response to injury. Problems with blood clotting can lead to excessive bleeding. Some mutations drastically reduce the activity of prothrombin and can lead to severe bleeding episodes. Other F2 gene mutations allow for a moderate amount of prothrombin activity, typically resulting in mild bleeding episodes.
Question: Is prothrombin 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 exudative vitreoretinopathy ?
Answer: Familial exudative vitreoretinopathy is a hereditary disorder that can cause progressive vision loss. This condition affects the retina, the specialized light-sensitive tissue that lines the back of the eye. The disorder prevents blood vessels from forming at the edges of the retina, which reduces the blood supply to this tissue. The signs and symptoms of familial exudative vitreoretinopathy vary widely, even within the same family. In many affected individuals, the retinal abnormalities never cause any vision problems. In others, a reduction in the retina's blood supply causes the retina to fold, tear, or separate from the back of the eye (retinal detachment). This retinal damage can lead to vision loss and blindness. Other eye abnormalities are also possible, including eyes that do not look in the same direction (strabismus) and a visible whiteness (leukocoria) in the normally black pupil. Some people with familial exudative vitreoretinopathy also have reduced bone mineral density, which weakens bones and increases the risk of fractures.
Question: How many people are affected by familial exudative vitreoretinopathy ?
Answer: The prevalence of familial exudative vitreoretinopathy is unknown. It appears to be rare, although affected people with normal vision may never come to medical attention.
Question: What are the genetic changes related to familial exudative vitreoretinopathy ?
Answer: Mutations in the FZD4, LRP5, and NDP genes can cause familial exudative vitreoretinopathy. These genes provide instructions for making proteins that participate in a chemical signaling pathway that affects the way cells and tissues develop. In particular, the proteins produced from the FZD4, LRP5, and NDP genes appear to play critical roles in the specialization of retinal cells and the establishment of a blood supply to the retina and the inner ear. The LRP5 protein also helps regulate bone formation. Mutations in the FZD4, LRP5, or NDP gene disrupt chemical signaling during early development, which interferes with the formation of blood vessels at the edges of the retina. The resulting abnormal blood supply to this tissue leads to retinal damage and vision loss in some people with familial exudative vitreoretinopathy. The eye abnormalities associated with familial exudative vitreoretinopathy tend to be similar no matter which gene is altered. However, affected individuals with LRP5 gene mutations often have reduced bone mineral density in addition to vision loss. Mutations in the other genes responsible for familial exudative vitreoretinopathy do not appear to affect bone density. In some cases, the cause of familial exudative vitreoretinopathy is unknown. Researchers believe that mutations in several as-yet-unidentified genes are responsible for the disorder in these cases.
Question: Is familial exudative vitreoretinopathy inherited ?
Answer: Familial exudative vitreoretinopathy has different inheritance patterns depending on the gene involved. Most commonly, the condition results from mutations in the FZD4 or LRP5 gene and has an autosomal dominant pattern of inheritance. Autosomal dominant inheritance means one copy of the altered gene in each cell is sufficient to cause the disorder. Most people with autosomal dominant familial exudative vitreoretinopathy inherit the altered gene from a parent, although the parent may not have any signs and symptoms associated with this disorder. Familial exudative vitreoretinopathy caused by LRP5 gene mutations can also have an autosomal recessive pattern of inheritance. Autosomal recessive inheritance means both copies of the gene in each cell have mutations. The parents of an individual with autosomal recessive familial exudative vitreoretinopathy each carry one copy of the mutated gene, but they do not have the disorder. When familial exudative vitreoretinopathy is caused by mutations in the NDP gene, it has an X-linked recessive pattern of inheritance. The NDP gene 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 disorders much more frequently than females. A characteristic of X-linked inheritance is that fathers cannot pass X-linked traits to their sons.

Question: What is (are) autosomal dominant vitreoretinochoroidopathy ?
Answer: Autosomal dominant vitreoretinochoroidopathy (ADVIRC) is a disorder that affects several parts of the eyes, including the clear gel that fills the eye (the vitreous), the light-sensitive tissue that lines the back of the eye (the retina), and the network of blood vessels within the retina (the choroid). The eye abnormalities in ADVIRC can lead to varying degrees of vision impairment, from mild reduction to complete loss, although some people with the condition have normal vision. The signs and symptoms of ADVIRC vary, even among members of the same family. Many affected individuals have microcornea, in which the clear front covering of the eye (cornea) is small and abnormally curved. The area behind the cornea can also be abnormally small, which is described as a shallow anterior chamber. Individuals with ADVIRC can develop increased pressure in the eyes (glaucoma) or clouding of the lens of the eye (cataract). In addition, some people have breakdown (degeneration) of the vitreous or the choroid. A characteristic feature of ADVIRC, visible with a special eye exam, is a circular band of excess coloring (hyperpigmentation) in the retina. This feature can help physicians diagnose the disorder. Affected individuals may also have white spots on the retina.
Question: How many people are affected by autosomal dominant vitreoretinochoroidopathy ?
Answer: ADVIRC is considered a rare disease. Its prevalence is unknown.
Question: What are the genetic changes related to autosomal dominant vitreoretinochoroidopathy ?
Answer: ADVIRC is caused by mutations in the BEST1 gene. The protein produced from this gene, called bestrophin-1, is thought to play a critical role in normal vision. Bestrophin-1 is found in a thin layer of cells at the back of the eye called the retinal pigment epithelium. This cell layer supports and nourishes the retina and is involved in growth and development of the eye, maintenance of the retina, and the normal function of specialized cells called photoreceptors that detect light and color. In the retinal pigment epithelium, bestrophin-1 functions as a channel that transports charged chlorine atoms (chloride ions) across the cell membrane. Mutations in the BEST1 gene alter how the gene's instructions are used to make bestrophin-1, which leads to production of versions of the protein that are missing certain segments or have extra segments. It is not clear how these versions of bestrophin affect chloride ion transport or lead to the eye abnormalities characteristic of ADVIRC. Researchers suspect that the abnormalities are related to defects in the retinal pigment epithelium or the photoreceptors.
Question: Is autosomal dominant vitreoretinochoroidopathy 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.

Question: What is (are) geleophysic dysplasia ?
Answer: Geleophysic dysplasia is an inherited condition that affects many parts of the body. It is characterized by abnormalities involving the bones, joints, heart, and skin. People with geleophysic dysplasia have short stature with very short hands and feet. Most also develop thickened skin and joint deformities called contractures, both of which significantly limit mobility. Affected individuals usually have a limited range of motion in their fingers, toes, wrists, and elbows. Additionally, contractures in the legs and hips cause many affected people to walk on their toes. The name of this condition, which comes from the Greek words for happy ("gelios") and nature ("physis"), is derived from the good-natured facial appearance seen in most affected individuals. The distinctive facial features associated with this condition include a round face with full cheeks, a small nose with upturned nostrils, a broad nasal bridge, a thin upper lip, upturned corners of the mouth, and a flat area between the upper lip and the nose (philtrum). Geleophysic dysplasia is also characterized by heart (cardiac) problems, particularly abnormalities of the cardiac valves. These valves normally control the flow of blood through the heart. In people with geleophysic dysplasia, the cardiac valves thicken, which impedes blood flow and increases blood pressure in the heart. Other heart problems have also been reported in people with geleophysic dysplasia; these include a narrowing of the artery from the heart to the lungs (pulmonary stenosis) and a hole between the two upper chambers of the heart (atrial septal defect). Other features of geleophysic dysplasia can include an enlarged liver (hepatomegaly) and recurrent respiratory and ear infections. In severe cases, a narrowing of the windpipe (tracheal stenosis) can cause serious breathing problems. As a result of heart and respiratory abnormalities, geleophysic dysplasia is often life-threatening in childhood. However, some affected people have lived into adulthood.
Question: How many people are affected by geleophysic dysplasia ?
Answer: Geleophysic dysplasia is a rare disorder whose prevalence is unknown. More than 30 affected individuals have been reported.
Question: What are the genetic changes related to geleophysic dysplasia ?
Answer: Geleophysic dysplasia results from mutations in the ADAMTSL2 gene. This gene provides instructions for making a protein whose function is unclear. The protein is found in the extracellular matrix, which is the intricate lattice of proteins and other molecules that forms in the spaces between cells. Studies suggest that the ADAMTSL2 protein may play a role in the microfibrillar network, which is an organized clustering of thread-like filaments (called microfibrils) in the extracellular matrix. This network provides strength and flexibility to tissues throughout the body. Mutations in the ADAMTSL2 protein likely change the protein's 3-dimensional structure. Through a process that is poorly understood, ADAMTSL2 gene mutations alter the microfibrillar network in many different tissues. Impairment of this essential network disrupts the normal functions of cells, which likely contributes to the varied signs and symptoms of geleophysic dysplasia. Researchers are working to determine how mutations in the ADAMTSL2 gene lead to short stature, heart disease, and the other features of this condition.
Question: Is geleophysic dysplasia 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) 2-hydroxyglutaric aciduria ?
Answer: 2-hydroxyglutaric aciduria is a condition that causes progressive damage to the brain. The major types of this disorder are called D-2-hydroxyglutaric aciduria (D-2-HGA), L-2-hydroxyglutaric aciduria (L-2-HGA), and combined D,L-2-hydroxyglutaric aciduria (D,L-2-HGA). The main features of D-2-HGA are delayed development, seizures, weak muscle tone (hypotonia), and abnormalities in the largest part of the brain (the cerebrum), which controls many important functions such as muscle movement, speech, vision, thinking, emotion, and memory. Researchers have described two subtypes of D-2-HGA, type I and type II. The two subtypes are distinguished by their genetic cause and pattern of inheritance, although they also have some differences in signs and symptoms. Type II tends to begin earlier and often causes more severe health problems than type I. Type II may also be associated with a weakened and enlarged heart (cardiomyopathy), a feature that is typically not found with type I. L-2-HGA particularly affects a region of the brain called the cerebellum, which is involved in coordinating movements. As a result, many affected individuals have problems with balance and muscle coordination (ataxia). Additional features of L-2-HGA can include delayed development, seizures, speech difficulties, and an unusually large head (macrocephaly). Typically, signs and symptoms of this disorder begin during infancy or early childhood. The disorder worsens over time, usually leading to severe disability by early adulthood. Combined D,L-2-HGA causes severe brain abnormalities that become apparent in early infancy. Affected infants have severe seizures, weak muscle tone (hypotonia), and breathing and feeding problems. They usually survive only into infancy or early childhood.
Question: How many people are affected by 2-hydroxyglutaric aciduria ?
Answer: 2-hydroxyglutaric aciduria is a rare disorder. D-2-HGA and L-2-HGA have each been reported to affect fewer than 150 individuals worldwide. Combined D,L-2-HGA appears to be even rarer, with only about a dozen reported cases.
Question: What are the genetic changes related to 2-hydroxyglutaric aciduria ?
Answer: The different types of 2-hydroxyglutaric aciduria result from mutations in several genes. D-2-HGA type I is caused by mutations in the D2HGDH gene; type II is caused by mutations in the IDH2 gene. L-2-HGA results from mutations in the L2HGDH gene. Combined D,L-2-HGA is caused by mutations in the SLC25A1 gene. The D2HGDH and L2HGDH genes provide instructions for making enzymes that are found in mitochondria, which are the energy-producing centers within cells. The enzymes break down compounds called D-2-hydroxyglutarate and L-2-hydroxyglutarate, respectively, as part of a series of reactions that produce energy for cell activities. Mutations in either of these genes lead to a shortage of functional enzyme, which allows D-2-hydroxyglutarate or L-2-hydroxyglutarate to build up in cells. At high levels, these compounds can damage cells and lead to cell death. Brain cells appear to be the most vulnerable to the toxic effects of these compounds, which may explain why the signs and symptoms of D-2-HGA type I and L-2-HGA primarily involve the brain. The IDH2 gene provides instructions for making an enzyme in mitochondria that normally produces a different compound. When the enzyme is altered by mutations, it takes on a new, abnormal function: production of the potentially toxic compound D-2-hydroxyglutarate. The resulting excess of this compound damages brain cells, leading to the signs and symptoms of D-2-HGA type II. It is unclear why an accumulation of D-2-hydroxyglutarate may be associated with cardiomyopathy in some people with this form of the condition. The SLC25A1 gene provides instructions for making a protein that transports certain molecules, such as citrate, in and out of mitochondria. Mutations in the SLC25A1 gene reduce the protein's function, which prevents it from carrying out this transport. Through processes that are not fully understood, a loss of this transport allows both D-2-hydroxyglutarate and L-2-hydroxyglutarate to build up, which damages brain cells. Researchers suspect that an imbalance of other molecules, particularly citrate, also contributes to the severe signs and symptoms of combined D,L-2-HGA.
