user: What are the genetic changes related to hereditary xanthinuria ?

assistant: Hereditary xanthinuria type I is caused by mutations in the XDH gene. This gene provides instructions for making an enzyme called xanthine dehydrogenase. This enzyme is involved in the normal breakdown of purines, which are building blocks of DNA and its chemical cousin, RNA. Specifically, xanthine dehydrogenase carries out the final two steps in the process, including the conversion of xanthine to uric acid (which is excreted in urine and feces). Mutations in the XDH gene reduce or eliminate the activity of xanthine dehydrogenase. As a result, the enzyme is not available to help carry out the last two steps of purine breakdown. Because xanthine is not converted to uric acid, affected individuals have high levels of xanthine and very low levels of uric acid in their blood and urine. The excess xanthine can cause damage to the kidneys and other tissues.  Hereditary xanthinuria type II results from mutations in the MOCOS gene. This gene provides instructions for making an enzyme called molybdenum cofactor sulfurase. This enzyme is necessary for the normal function of xanthine dehydrogenase, described above, and another enzyme called aldehyde oxidase. Mutations in the MOCOS gene prevent xanthine dehydrogenase and aldehyde oxidase from being turned on (activated). The loss of xanthine dehydrogenase activity prevents the conversion of xanthine to uric acid, leading to an accumulation of xanthine in the kidneys and other tissues. The loss of aldehyde oxidase activity does not appear to cause any health problems.
user: Is hereditary xanthinuria inherited ?

assistant: 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.

user: What is (are) keratitis-ichthyosis-deafness syndrome ?

assistant: Keratitis-ichthyosis-deafness (KID) syndrome is characterized by eye problems, skin abnormalities, and hearing loss.  People with KID syndrome usually have keratitis, which is inflammation of the front surface of the eye (the cornea). The keratitis may cause pain, increased sensitivity to light (photophobia), abnormal blood vessel growth over the cornea (neovascularization), and scarring. Over time, affected individuals experience a loss of sharp vision (reduced visual acuity); in severe cases the keratitis can lead to blindness.  Most people with KID syndrome have thick, hard skin on the palms of the hands and soles of the feet (palmoplantar keratoderma). Affected individuals also have thick, reddened patches of skin (erythrokeratoderma) that are dry and scaly (ichthyosis). These dry patches can occur anywhere on the body, although they most commonly affect the neck, groin, and armpits. Breaks in the skin often occur and may lead to infections. In severe cases these infections can be life-threatening, especially in infancy. Approximately 12 percent of people with KID syndrome develop a type of skin cancer called squamous cell carcinoma, which may also affect mucous membranes such as the lining of the mouth.  Partial hair loss is a common feature of KID syndrome, and often affects the eyebrows and eyelashes. Affected individuals may also have small, abnormally formed nails.  Hearing loss in this condition is usually profound, but occasionally is less severe.
user: How many people are affected by keratitis-ichthyosis-deafness syndrome ?

assistant: KID syndrome is a rare disorder. Its prevalence is unknown. Approximately 100 cases have been reported.
user: What are the genetic changes related to keratitis-ichthyosis-deafness syndrome ?

assistant: KID syndrome is caused by mutations in the GJB2 gene. This gene provides instructions for making a protein called gap junction beta 2, more commonly known as connexin 26. Connexin 26 is a member of the connexin protein family. Connexin proteins form channels called gap junctions that permit the transport of nutrients, charged atoms (ions), and signaling molecules between neighboring cells that are in contact with each other. Gap junctions made with connexin 26 transport potassium ions and certain small molecules.  Connexin 26 is found in cells throughout the body, including the inner ear and the skin. In the inner ear, channels made from connexin 26 are found in a snail-shaped structure called the cochlea. These channels may help to maintain the proper level of potassium ions required for the conversion of sound waves to electrical nerve impulses. This conversion is essential for normal hearing. In addition, connexin 26 may be involved in the maturation of certain cells in the cochlea. Connexin 26 also plays a role in the growth and maturation of the outermost layer of skin (the epidermis).  The GJB2 gene mutations that cause KID syndrome change single protein building blocks (amino acids) in connexin 26. The mutations are thought to result in channels that constantly leak ions, which impairs the health of the cells and increases cell death. Death of cells in the skin and the inner ear may underlie the ichthyosis and deafness that occur in KID syndrome. It is unclear how GJB2 gene mutations affect the eye.  Because at least one of the GJB2 gene mutations identified in people with KID syndrome also occurs in hystrix-like ichthyosis with deafness (HID), a disorder with similar features but without keratitis, many researchers categorize KID syndrome and HID as a single disorder, which they call KID/HID. It is not known why some people with this mutation have eye problems while others do not.
user: Is keratitis-ichthyosis-deafness syndrome inherited ?

assistant: KID syndrome is usually 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. However, most cases result from new mutations in the gene and occur in people with no history of the disorder in their family.  A few families have had a condition resembling KID syndrome with an autosomal recessive pattern of inheritance. In autosomal recessive inheritance, both copies of a 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. Affected individuals in these families have liver disease, which is not a feature of the autosomal dominant form. The autosomal recessive condition is sometimes called Desmons syndrome. It is unknown whether it is also caused by GJB2 gene mutations.

user: What is (are) Kallmann syndrome ?

assistant: Kallmann syndrome is a condition characterized by delayed or absent puberty and an impaired sense of smell.  This disorder is a form of hypogonadotropic hypogonadism (HH), which is a condition affecting the production of hormones that direct sexual development. Males with hypogonadotropic hypogonadism are often born with an unusually small penis (micropenis) and undescended testes (cryptorchidism). At puberty, most affected individuals do not develop secondary sex characteristics, such as the growth of facial hair and deepening of the voice in males. Affected females usually do not begin menstruating at puberty and have little or no breast development. In some people, puberty is incomplete or delayed.  In Kallmann syndrome, the sense of smell is either diminished (hyposmia) or completely absent (anosmia). This feature distinguishes Kallmann syndrome from most other forms of hypogonadotropic hypogonadism, which do not affect the sense of smell. Many people with Kallmann syndrome are not aware that they are unable to detect odors until the impairment is discovered through testing.  The features of Kallmann syndrome vary, even among affected people in the same family. Additional signs and symptoms can include a failure of one kidney to develop (unilateral renal agenesis), a cleft lip with or without an opening in the roof of the mouth (a cleft palate), abnormal eye movements, hearing loss, and abnormalities of tooth development. Some affected individuals have a condition called bimanual synkinesis, in which the movements of one hand are mirrored by the other hand. Bimanual synkinesis can make it difficult to do tasks that require the hands to move separately, such as playing a musical instrument.  Researchers have identified four forms of Kallmann syndrome, designated types 1 through 4, which are distinguished by their genetic cause. The four types are each characterized by hypogonadotropic hypogonadism and an impaired sense of smell. Additional features, such as a cleft palate, seem to occur only in types 1 and 2.
user: How many people are affected by Kallmann syndrome ?

assistant: Kallmann syndrome is estimated to affect 1 in 10,000 to 86,000 people and occurs more often in males than in females. Kallmann syndrome 1 is the most common form of the disorder.
user: What are the genetic changes related to Kallmann syndrome ?

assistant: Mutations in the ANOS1, FGFR1, PROKR2, and PROK2 genes cause Kallmann syndrome. ANOS1 gene mutations are responsible for Kallmann syndrome 1. Kallmann syndrome 2 results from mutations in the FGFR1 gene. Mutations in the PROKR2 and PROK2 genes cause Kallmann syndrome types 3 and 4, respectively.  The genes associated with Kallmann syndrome play a role in the development of certain areas of the brain before birth. Although some of their specific functions are unclear, these genes appear to be involved in the formation and movement (migration) of a group of nerve cells that are specialized to process smells (olfactory neurons). These nerve cells come together into a bundle called the olfactory bulb, which is critical for the perception of odors. The ANOS1, FGFR1, PROKR2, and PROK2 genes also play a role in the migration of neurons that produce a hormone called gonadotropin-releasing hormone (GnRH). GnRH controls the production of several other hormones that direct sexual development before birth and during puberty. These hormones are important for the normal function of the gonads (ovaries in women and testes in men).  Studies suggest that mutations in the ANOS1, FGFR1, PROKR2, or PROK2 gene disrupt the migration of olfactory nerve cells and GnRH-producing nerve cells in the developing brain. If olfactory nerve cells do not extend to the olfactory bulb, a person's sense of smell will be impaired or absent. Misplacement of GnRH-producing neurons prevents the production of certain sex hormones, which interferes with normal sexual development and causes the characteristic features of hypogonadotropic hypogonadism. It is unclear how gene mutations lead to the other possible signs and symptoms of Kallmann syndrome. Because the features of this condition vary among individuals, researchers suspect that additional genetic and environmental factors may be involved.  Together, mutations in the ANOS1, FGFR1, PROKR2, and PROK2 genes account for 25 percent to 30 percent of all cases of Kallmann syndrome. In cases without an identified mutation in one of these genes, the cause of the condition is unknown. Researchers are looking for other genes that can cause this disorder.
user: Is Kallmann syndrome inherited ?

assistant: Kallmann syndrome 1 (caused by ANOS1 gene mutations) has an X-linked recessive pattern of inheritance. The ANOS1 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 must be present in both copies of the gene to cause the disorder. 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.  Most cases of Kallmann syndrome 1 are described as simplex, which means only one person in a family is affected. Some affected people inherit a ANOS1 gene mutation from their mothers, who carry a single mutated copy of the gene in each cell. Other people have the condition as a result of a new mutation in the ANOS1 gene.  Other forms of Kallmann syndrome can be 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.  In several families, Kallmann syndrome has shown 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 an autosomal recessive condition each carry one copy of the mutated gene, but they typically do not show signs and symptoms of the condition.

user: What is (are) centronuclear myopathy ?

assistant: Centronuclear myopathy is a condition characterized by muscle weakness (myopathy) and wasting (atrophy) in the skeletal muscles, which are the muscles used for movement. The severity of centronuclear myopathy varies among affected individuals, even among members of the same family.  People with centronuclear myopathy begin experiencing muscle weakness at any time from birth to early adulthood. The muscle weakness slowly worsens over time and can lead to delayed development of motor skills, such as crawling or walking; muscle pain during exercise; and difficulty walking. Some affected individuals may need wheelchair assistance as the muscles atrophy and weakness becomes more severe. In rare instances, the muscle weakness improves over time.  Some people with centronuclear myopathy experience mild to severe breathing problems related to the weakness of muscles needed for breathing. People with centronuclear myopathy may have droopy eyelids (ptosis) and weakness in other facial muscles, including the muscles that control eye movement. People with this condition may also have foot abnormalities, a high arch in the roof of the mouth (high-arched palate), and abnormal side-to-side curvature of the spine (scoliosis). Rarely, individuals with centronuclear myopathy have a weakened heart muscle (cardiomyopathy), disturbances in nerve function (neuropathy), or intellectual disability.  A key feature of centronuclear myopathy is the displacement of the nucleus in muscle cells, which can be viewed under a microscope. Normally the nucleus is found at the edges of the rod-shaped muscle cells, but in people with centronuclear myopathy the nucleus is located in the center of these cells. How the change in location of the nucleus affects muscle cell function is unknown.
user: How many people are affected by centronuclear myopathy ?

assistant: Centronuclear myopathy is a rare condition; its exact prevalence is unknown.
user: What are the genetic changes related to centronuclear myopathy ?

assistant: Centronuclear myopathy is most often caused by mutations in the DNM2, BIN1, or TTN gene. The proteins produced from the DNM2 and BIN1 genes are involved in endocytosis, a process that brings substances into the cell. The protein produced from the BIN1 gene plays an additional role in the formation of tube-like structures called transverse tubules (or T tubules), which are found within the membrane of muscle fibers. These tubules help transmit the electrical impulses necessary for normal muscle tensing (contraction) and relaxation. The protein produced from the DNM2 gene also regulates the actin cytoskeleton, which makes up the muscle fiber's structural framework. DNM2 and BIN1 gene mutations lead to abnormal muscle fibers that cannot contract and relax normally, resulting in muscle weakness.  The TTN gene provides instructions for making a protein called titin that is an essential component of muscle fiber 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. TTN gene mutations decrease or alter titin's activity in muscle fibers. It is unclear how these mutations lead to centronuclear myopathy, but it is likely that the altered protein cannot interact with other proteins in the sarcomere, leading to dysfunction of the sarcomere. Abnormal sarcomeres prevent muscle fibers from contracting and relaxing normally, resulting in muscle weakness.  Some people with centronuclear myopathy do not have identified mutations in the DNM2, BIN1, or TTN genes. Mutations in other genes associated with this condition are found in a small percentage of cases. Some males with signs and symptoms of severe centronuclear myopathy may have a condition called X-linked myotubular myopathy, which is similar to centronuclear myopathy, and is often considered a subtype of the condition, but has a different genetic cause. In some people with centronuclear myopathy, the cause of the disorder is unknown. Researchers are looking for additional genes that are associated with centronuclear myopathy.
user: Is centronuclear myopathy inherited ?

assistant: When centronuclear myopathy is caused by mutations in the DNM2 gene, it is inherited in an autosomal dominant pattern, which means one copy of the altered DNM2 gene in each cell is sufficient to cause the disorder. Rarely, BIN1 gene mutations that are inherited in an autosomal dominant pattern can cause centronuclear myopathy.  Centronuclear myopathy caused by TTN gene mutations and most cases caused by BIN1 gene mutations are 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.  Other cases of centronuclear myopathy that are not caused by these genes are typically inherited in an autosomal recessive manner, although some follow an autosomal dominant pattern.

user: What is (are) glutaric acidemia type II ?

assistant: Glutaric acidemia type II is an inherited disorder that interferes with the body's ability to break down proteins and fats to produce energy. Incompletely processed proteins and fats can build up in the body and cause the blood and tissues to become too acidic (metabolic acidosis).  Glutaric acidemia type II usually appears in infancy or early childhood as a sudden episode called a metabolic crisis, in which acidosis and low blood sugar (hypoglycemia) cause weakness, behavior changes such as poor feeding and decreased activity, and vomiting. These metabolic crises, which can be life-threatening, may be triggered by common childhood illnesses or other stresses.  In the most severe cases of glutaric acidemia type II, affected individuals may also be born with physical abnormalities. These may include brain malformations, an enlarged liver (hepatomegaly), a weakened and enlarged heart (dilated cardiomyopathy), fluid-filled cysts and other malformations of the kidneys, unusual facial features, and genital abnormalities. Glutaric acidemia type II may also cause a characteristic odor resembling that of sweaty feet.  Some affected individuals have less severe symptoms that begin later in childhood or in adulthood. In the mildest forms of glutaric acidemia type II, muscle weakness developing in adulthood may be the first sign of the disorder.
user: How many people are affected by glutaric acidemia type II ?

assistant: Glutaric acidemia type II is a very rare disorder; its precise incidence is unknown. It has been reported in several different ethnic groups.
user: What are the genetic changes related to glutaric acidemia type II ?

assistant: Mutations in any of three genes, ETFA, ETFB, and ETFDH, can result in glutaric acidemia type II. The ETFA and ETFB genes provide instructions for producing two protein segments, or subunits, that come together to make an enzyme called electron transfer flavoprotein. The ETFDH gene provides instructions for making another enzyme called electron transfer flavoprotein dehydrogenase.  Glutaric acidemia type II is caused by a deficiency in either of these two enzymes. Electron transfer flavoprotein and electron transfer flavoprotein dehydrogenase are normally active in the mitochondria, which are the energy-producing centers of cells. These enzymes help break down proteins and fats to provide energy for the body. When one of the enzymes is defective or missing, partially broken down nutrients accumulate in the cells and damage them, causing the signs and symptoms of glutaric acidemia type II.  People with mutations that result in a complete loss of either enzyme produced from the ETFA, ETFB or ETFDH genes are likely to experience the most severe symptoms of glutaric acidemia type II. Mutations that allow the enzyme to retain some activity may result in milder forms of the disorder.
user: Is glutaric acidemia type II inherited ?

assistant: 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.
