Question: What are the genetic changes related to platyspondylic lethal skeletal dysplasia, Torrance type ?
Answer: Platyspondylic lethal skeletal dysplasia, Torrance type is one of a spectrum of skeletal disorders caused by mutations in the COL2A1 gene. This gene provides instructions for making a protein that forms type II collagen. This type of collagen is found mostly in the clear gel that fills the eyeball (the vitreous) and in cartilage. Cartilage is a tough, flexible tissue that makes up much of the skeleton during early development. Most cartilage is later converted to bone, except for the cartilage that continues to cover and protect the ends of bones and is present in the nose and external ears. Type II collagen is essential for the normal development of bones and other connective tissues that form the body's supportive framework.  All of the COL2A1 mutations that have been found to cause platyspondylic lethal skeletal dysplasia, Torrance type occur in a region of the protein called the C-propeptide domain. These mutations interfere with the assembly of type II collagen molecules, reducing the amount of this type of collagen in the body. Instead of forming collagen molecules, the abnormal COL2A1 protein builds up in cartilage cells (chondrocytes). These changes disrupt the normal development of bones and other connective tissues, leading to the skeletal abnormalities characteristic of platyspondylic lethal skeletal dysplasia, Torrance type.

Question: What is (are) PDGFRB-associated chronic eosinophilic leukemia ?
Answer: PDGFRB-associated chronic eosinophilic leukemia is a type of cancer of blood-forming cells. It is characterized by an elevated number of white blood cells called eosinophils in the blood. These cells help fight infections by certain parasites and are involved in the inflammation associated with allergic reactions. However, these circumstances do not account for the increased number of eosinophils in PDGFRB-associated chronic eosinophilic leukemia. Some people with this condition have an increased number of other types of white blood cells, such as neutrophils or mast cells, in addition to eosinophils. People with this condition can have an enlarged spleen (splenomegaly) or enlarged liver (hepatomegaly). Some affected individuals develop skin rashes, likely as a result of an abnormal immune response due to the increased number of eosinophils.

Question: What are the genetic changes related to PDGFRB-associated chronic eosinophilic leukemia ?
Answer: PDGFRB-associated chronic eosinophilic leukemia is caused by genetic rearrangements that join part of the PDGFRB gene with part of another gene. At least 20 genes have been found that fuse with the PDGFRB gene to cause PDGFRB-associated chronic eosinophilic leukemia. The most common genetic abnormality in this condition results from a rearrangement (translocation) of genetic material that brings part of the PDGFRB gene on chromosome 5 together with part of the ETV6 gene on chromosome 12, creating the ETV6-PDGFRB fusion gene.  The PDGFRB gene provides instructions for making a protein that plays a role in turning on (activating) signaling pathways that control many cell processes, including cell growth and division (proliferation). The ETV6 gene provides instructions for making a protein that turns off (represses) gene activity. This protein is important in development before birth and in regulating blood cell formation. The protein produced from the ETV6-PDGFRB fusion gene, called ETV6/PDGFR, functions differently than the proteins normally produced from the individual genes. Like the normal PDGFR protein, the ETV6/PDGFR fusion protein turns on signaling pathways. However, the fusion protein does not need to be turned on to be active, so the signaling pathways are constantly turned on (constitutively activated). The fusion protein is unable to repress gene activity regulated by the normal ETV6 protein, so gene activity is increased. The constitutively active signaling pathways and abnormal gene activity increase the proliferation and survival of cells.  When the ETV6-PDGFRB fusion gene mutation occurs in cells that develop into blood cells, the growth of eosinophils (and occasionally other blood cells, such as neutrophils and mast cells) is poorly controlled, leading to PDGFRB-associated chronic eosinophilic leukemia. It is unclear why eosinophils are preferentially affected by this genetic change.

Question: Is PDGFRB-associated chronic eosinophilic leukemia inherited ?
Answer: PDGFRB-associated chronic eosinophilic leukemia is not inherited and occurs in people with no history of the condition in their families. Chromosomal rearrangements that lead to a PDGFRB fusion gene are somatic mutations, which are mutations acquired during a person's lifetime and present only in certain cells. The somatic mutation occurs initially in a single cell, which continues to grow and divide, producing a group of cells with the same mutation (a clonal population).

Question: What is (are) Usher syndrome ?
Answer: Usher syndrome is a condition characterized by hearing loss or deafness and progressive vision loss. The loss of vision is caused by an eye disease called retinitis pigmentosa (RP), which affects the layer of light-sensitive tissue at the back of the eye (the retina). Vision loss occurs as the light-sensing cells of the retina gradually deteriorate. Night vision loss begins first, followed by blind spots that develop in the side (peripheral) vision. Over time, these blind spots enlarge and merge to produce tunnel vision. In some cases of Usher syndrome, vision is further impaired by clouding of the lens of the eye (cataracts). Many people with retinitis pigmentosa retain some central vision throughout their lives, however.  Researchers have identified three major types of Usher syndrome, designated as types I, II, and III. These types are distinguished by their severity and the age when signs and symptoms appear. Type I is further divided into seven distinct subtypes, designated as types IA through IG. Usher syndrome type II has at least three described subtypes, designated as types IIA, IIB, and IIC.  Individuals with Usher syndrome type I are typically born completely deaf or lose most of their hearing within the first year of life. Progressive vision loss caused by retinitis pigmentosa becomes apparent in childhood. This type of Usher syndrome also includes problems with the inner ear that affect balance. As a result, children with the condition begin sitting independently and walking later than usual.  Usher syndrome type II is characterized by hearing loss from birth and progressive vision loss that begins in adolescence or adulthood. The hearing loss associated with this form of Usher syndrome ranges from mild to severe and mainly affects high tones. Affected children have problems hearing high, soft speech sounds, such as those of the letters d and t. The degree of hearing loss varies within and among families with this condition. Unlike other forms of Usher syndrome, people with type II do not have difficulties with balance caused by inner ear problems.  People with Usher syndrome type III experience progressive hearing loss and vision loss beginning in the first few decades of life. Unlike the other forms of Usher syndrome, infants with Usher syndrome type III are usually born with normal hearing. Hearing loss typically begins during late childhood or adolescence, after the development of speech, and progresses over time. By middle age, most affected individuals are profoundly deaf. Vision loss caused by retinitis pigmentosa also develops in late childhood or adolescence. People with Usher syndrome type III may also experience difficulties with balance due to inner ear problems. These problems vary among affected individuals, however.

Question: How many people are affected by Usher syndrome ?
Answer: Usher syndrome is thought to be responsible for 3 percent to 6 percent of all childhood deafness and about 50 percent of deaf-blindness in adults. Usher syndrome type I is estimated to occur in at least 4 per 100,000 people. It may be more common in certain ethnic populations, such as people with Ashkenazi (central and eastern European) Jewish ancestry and the Acadian population in Louisiana. Type II is thought to be the most common form of Usher syndrome, although the frequency of this type is unknown. Type III Usher syndrome accounts for only a small percentage of all Usher syndrome cases in most populations. This form of the condition is more common in the Finnish population, however, where it accounts for about 40 percent of all cases.

Question: What are the genetic changes related to Usher syndrome ?
Answer: Mutations in the ADGRV1, CDH23, CLRN1, MYO7A, PCDH15, USH1C, USH1G, and USH2A genes can cause Usher syndrome.  The genes related to Usher syndrome provide instructions for making proteins that play important roles in normal hearing, balance, and vision. They function in the development and maintenance of hair cells, which are sensory cells in the inner ear that help transmit sound and motion signals to the brain. In the retina, these genes are also involved in determining the structure and function of light-sensing cells called rods and cones. In some cases, the exact role of these genes in hearing and vision is unknown. Most of the mutations responsible for Usher syndrome lead to a loss of hair cells in the inner ear and a gradual loss of rods and cones in the retina. Degeneration of these sensory cells causes hearing loss, balance problems, and vision loss characteristic of this condition.  Usher syndrome type I can result from mutations in the CDH23, MYO7A, PCDH15, USH1C, or USH1G gene. At least two other unidentified genes also cause this form of Usher syndrome.  Usher syndrome type II is caused by mutations in at least four genes. Only two of these genes, ADGRV1 and USH2A, have been identified.  Mutations in at least two genes are responsible for Usher syndrome type III; however, CLRN1 is the only gene that has been identified.

Question: What is (are) mal de Meleda ?
Answer: Mal de Meleda is a rare skin disorder that begins in early infancy. Affected individuals have a condition known as palmoplantar keratoderma, in which the skin of the palms of the hands and soles of the feet becomes thick, hard, and callused. In mal de Meleda, the thickened skin is also found on the back of the hands and feet and on the wrists and ankles. In addition, affected individuals may have rough, thick pads on the joints of the fingers and toes and on the elbows and knees. Some people with mal de Meleda have recurrent fungal infections in the thickened skin, which can lead to a strong odor. Other features of this disorder can include short fingers and toes (brachydactyly), nail abnormalities, red skin around the mouth, and excessive sweating (hyperhidrosis).

Question: What are the genetic changes related to mal de Meleda ?
Answer: Mal de Meleda is caused by mutations in the SLURP1 gene. This gene provides instructions for making a protein that interacts with other proteins, called receptors, and is likely involved in signaling within cells. Studies show that the SLURP-1 protein can attach (bind) to nicotinic acetylcholine receptors (nAChRs) in the skin. Through interaction with these receptors, the SLURP-1 protein is thought to be involved in controlling the growth and division (proliferation), maturation (differentiation), and survival of skin cells.  Mutations in the SLURP1 gene lead to little or no SLURP-1 protein in the body. It is unclear how a lack of this protein leads to the skin problems that occur in mal de Meleda. Researchers speculate that without SLURP-1, the activity of genes controlled by nAChR signaling is altered, leading to overgrowth of skin cells or survival of cells that normally would have died. The excess of cells can result in skin thickening. It is unclear why skin on the hands and feet is particularly affected.

Question: What is (are) Salih myopathy ?
Answer: Salih myopathy is an inherited muscle disease that affects the skeletal muscles, which are used for movement, and the heart (cardiac) muscle. This condition is characterized by skeletal muscle weakness that becomes apparent in early infancy. Affected individuals have delayed development of motor skills, such as sitting, standing, and walking. Beginning later in childhood, people with Salih myopathy may also develop joint deformities called contractures that restrict the movement of the neck and back. Scoliosis, which is an abnormal side-to-side curvature of the spine, also develops in late childhood.  A form of heart disease called dilated cardiomyopathy is another feature of Salih myopathy. Dilated cardiomyopathy enlarges and weakens the cardiac muscle, preventing the heart from pumping blood efficiently. Signs and symptoms of this condition can include an irregular heartbeat (arrhythmia), shortness of breath, extreme tiredness (fatigue), and swelling of the legs and feet. The heart abnormalities associated with Salih myopathy usually become apparent in childhood, after the skeletal muscle abnormalities. The heart disease worsens quickly, and it often causes heart failure and sudden death in adolescence or early adulthood.

Question: What are the genetic changes related to Salih myopathy ?
Answer: Salih myopathy is caused by mutations in the TTN gene. This gene provides instructions for making a protein called titin, which plays an important role in skeletal and cardiac muscle function.  Within muscle cells, titin is an essential component of 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. Titin has several functions within sarcomeres. One of this protein's 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 responsible for Salih myopathy lead to the production of an abnormally short version of titin. The defective protein disrupts the function of sarcomeres, which prevents skeletal and cardiac muscle from contracting normally. These muscle abnormalities underlie the features of Salih myopathy, including skeletal muscle weakness and dilated cardiomyopathy.

Question: What is (are) hereditary antithrombin deficiency ?
Answer: Hereditary antithrombin deficiency is a disorder of blood clotting. People with this condition are at higher than average risk for developing abnormal blood clots, particularly a type of clot that occurs in the deep veins of the legs. This type of clot is called a deep vein thrombosis (DVT). Affected individuals also have an increased risk of developing a pulmonary embolism (PE), which is a clot that travels through the bloodstream and lodges in the lungs. In hereditary antithrombin deficiency, abnormal blood clots usually form only in veins, although they may rarely occur in arteries.  About half of people with hereditary antithrombin deficiency will develop at least one abnormal blood clot during their lifetime. These clots usually develop after adolescence.  Other factors can increase the risk of abnormal blood clots in people with hereditary antithrombin deficiency. These factors include increasing age, surgery, or immobility. The combination of hereditary antithrombin deficiency and other inherited disorders of blood clotting can also influence risk. Women with hereditary antithrombin deficiency are at increased risk of developing an abnormal blood clot during pregnancy or soon after delivery. They also may have an increased risk for pregnancy loss (miscarriage) or stillbirth.

Question: What are the genetic changes related to hereditary antithrombin deficiency ?
Answer: Hereditary antithrombin deficiency is caused by mutations in the SERPINC1 gene. This gene provides instructions for producing a protein called antithrombin (previously known as antithrombin III). This protein is found in the bloodstream and is important for controlling blood clotting. Antithrombin blocks the activity of proteins that promote blood clotting, especially a protein called thrombin.  Most of the mutations that cause hereditary antithrombin deficiency change single protein building blocks (amino acids) in antithrombin, which disrupts its ability to control blood clotting. Individuals with this condition do not have enough functional antithrombin to inactivate clotting proteins, which results in the increased risk of developing abnormal blood clots.

Question: Is hereditary antithrombin deficiency inherited ?
Answer: Hereditary antithrombin deficiency is typically inherited in an autosomal dominant pattern, which means one altered copy of the SERPINC1 gene in each cell is sufficient to cause the disorder. Inheriting two altered copies of this gene in each cell is usually incompatible with life; however, a few severely affected individuals have been reported with mutations in both copies of the SERPINC1 gene in each cell.
