What are the genetic changes related to antiphospholipid syndrome ? 

The genetic cause of antiphospholipid syndrome is unknown. This condition is associated with the presence of three abnormal immune proteins (antibodies) in the blood: lupus anticoagulant, anticardiolipin, and anti-B2 glycoprotein I. Antibodies normally bind to specific foreign particles and germs, marking them for destruction, but the antibodies in antiphospholipid syndrome attack normal human proteins. When these antibodies attach (bind) to proteins, the proteins change shape and bind to other molecules and receptors on the surface of cells. Binding to cells, particularly immune cells, turns on (activates) the blood clotting pathway and other immune responses.  The production of lupus anticoagulant, anticardiolipin, and anti-B2 glycoprotein I may coincide with exposure to foreign invaders, such as viruses and bacteria, that are similar to normal human proteins. Exposure to these foreign invaders may cause the body to produce antibodies to fight the infection, but because the invaders are so similar to the body's own proteins, the antibodies also attack the human proteins. Similar triggers may occur during pregnancy when a woman's physiology, particularly her immune system, adapts to accommodate the developing fetus. These changes during pregnancy may explain the high rate of affected females.  Certain genetic variations (polymorphisms) in a few genes have been found in people with antiphospholipid syndrome and may predispose individuals to produce the specific antibodies known to contribute to the formation of thromboses. However, the contribution of these genetic changes to the development of the condition is unclear.  People who test positive for all three antibodies but have not had a thrombosis or recurrent miscarriages are said to be antiphospholipid carriers. These individuals are at greater risk of developing a thrombosis than is the general population.
Is antiphospholipid syndrome inherited ? 

Most cases of antiphospholipid syndrome are sporadic, which means they occur in people with no history of the disorder in their family. Rarely, the condition has been reported to run in families; however, it does not have a clear pattern of inheritance. Multiple genetic and environmental factors likely play a part in determining the risk of developing antiphospholipid syndrome.

What is (are) adiposis dolorosa ? 

Adiposis dolorosa is a condition characterized by painful folds of fatty (adipose) tissue or the growth of multiple noncancerous (benign) fatty tumors called lipomas. This condition occurs most often in women who are overweight or obese, and signs and symptoms typically appear between ages 35 and 50.  In people with adiposis dolorosa, abnormal fatty tissue or lipomas can occur anywhere on the body but are most often found on the torso, buttocks, and upper parts of the arms and legs. Lipomas usually feel like firm bumps (nodules) under the skin. The growths cause burning or aching that can be severe. In some people, the pain comes and goes, while in others it is continuous. Movement or pressure on adipose tissue or lipomas can make the pain worse.  Other signs and symptoms that have been reported to occur with adiposis dolorosa include general weakness and tiredness (fatigue), depression, irritability, confusion, recurrent seizures (epilepsy), and a progressive decline in intellectual function (dementia). These problems do not occur in everyone with adiposis dolorosa, and it is unclear whether they are directly related to the condition.
How many people are affected by adiposis dolorosa ? 

Adiposis dolorosa is a rare condition whose prevalence is unknown. For reasons that are unclear, it occurs up to 30 times more often in women than in men.
What are the genetic changes related to adiposis dolorosa ? 

The cause of adiposis dolorosa is unknown. The condition is thought to have a genetic component because a few families with multiple affected family members have been reported. However, no associated genes have been identified.  Several other possible causes of adiposis dolorosa have been suggested, although none have been confirmed. They include the use of medications called corticosteroids, dysfunction of the endocrine system (which produces hormones), or changes in the deposition and breakdown of fat (adipose tissue metabolism). Researchers have also suggested that adiposis dolorosa could be an autoimmune disorder, which occurs when the immune system malfunctions and attacks the body's own tissues and organs. However, there is no firm evidence that the condition is related to abnormal inflammation or other immune system malfunction.  It is unknown why adiposis dolorosa usually occurs in people who are overweight or obese, or why the signs and symptoms do not appear until mid-adulthood.
Is adiposis dolorosa inherited ? 

Most cases of adiposis dolorosa are sporadic, which means they occur in people with no history of the disorder in their family.  A small number of familial cases of adiposis dolorosa have been reported. When the condition runs in families, it appears to have an autosomal dominant pattern of inheritance because affected individuals inherit the condition from one affected parent. This pattern of inheritance suggests that one copy of an altered gene in each cell is sufficient to cause the disorder.

What is (are) CATSPER1-related nonsyndromic male infertility ? 

CATSPER1-related nonsyndromic male infertility is a condition that affects the function of sperm, leading to an inability to father children. Males with this condition produce sperm that have decreased movement (motility). Affected men may also produce a smaller than usual number of sperm cells or sperm cells that are abnormally shaped. Men with CATSPER1-related nonsyndromic male infertility do not have any other symptoms related to this condition.
How many people are affected by CATSPER1-related nonsyndromic male infertility ? 

The prevalence of CATSPER1-related nonsyndromic male infertility is unknown.
What are the genetic changes related to CATSPER1-related nonsyndromic male infertility ? 

Mutations in the CATSPER1 gene cause CATSPER1-related nonsyndromic male infertility. The CATSPER1 gene provides instructions for producing a protein that is found in the tail of sperm cells. The CATSPER1 protein is involved in the movement of the sperm tail, which propels the sperm forward and is required for sperm cells to push through the outside membrane of the egg cell during fertilization.  CATSPER1 gene mutations result in the production of a CATSPER1 protein that may be altered, nonfunctional, or quickly broken down (degraded) by the cell. Sperm cells missing a functional CATSPER1 protein have decreased motion in their tails and move more slowly than normal. Sperm cells lacking functional CATSPER1 protein cannot push through the outside membrane of the egg cell. As a result, sperm cells cannot reach the inside of the egg cell to achieve fertilization.
Is CATSPER1-related nonsyndromic male infertility inherited ? 

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 symptoms of the condition.  Males with two CATSPER1 gene mutations in each cell have CATSPER1-related nonsyndromic male infertility. Females with two CATSPER1 gene mutations in each cell have no symptoms because the mutations only affect sperm function, and women do not produce sperm.

What is (are) Aicardi-Goutieres syndrome ? 

Aicardi-Goutieres syndrome is a disorder that mainly affects the brain, the immune system, and the skin.  Most newborns with Aicardi-Goutieres syndrome do not show any signs or symptoms of the disorder at birth. However, about 20 percent are born with a combination of features that include an enlarged liver and spleen (hepatosplenomegaly), elevated blood levels of liver enzymes, a decrease in blood platelets (thrombocytopenia), and abnormal neurological responses. While this combination of signs and symptoms is typically associated with the immune system's response to congenital viral infection, no actual infection is found in these infants. For this reason, Aicardi-Goutieres syndrome is sometimes referred to as a "mimic of congenital infection."  Within the first year of life most individuals with Aicardi-Goutieres syndrome experience an episode of severe brain dysfunction (encephalopathy), typically lasting for several months. During this phase of the disorder, affected babies are usually extremely irritable and do not feed well. They may develop intermittent fevers in the absence of infection (sterile pyrexias) and may have seizures. They stop developing new skills and begin losing skills they had already acquired (developmental regression). Growth of the brain and skull slows down, resulting in an abnormally small head size (microcephaly). In this phase of the disorder, white blood cells and molecules associated with inflammation can be detected in the cerebrospinal fluid, which is the fluid that surrounds the brain and spinal cord (central nervous system). These abnormal findings are consistent with inflammation and tissue damage in the central nervous system.  The encephalopathic phase of Aicardi-Goutieres syndrome leaves behind permanent neurological damage that is usually severe. Medical imaging reveals deterioration of white matter in the brain (leukodystrophy). White matter consists of nerve fibers covered by myelin, which is a substance that insulates and protects nerves. Affected individuals also have abnormal deposits of calcium (calcification) in the brain.  Most people with Aicardi-Goutieres syndrome have profound intellectual disability. They also have significant neuromuscular problems including muscle stiffness (spasticity); involuntary tensing of various muscles (dystonia), especially those in the arms; and weak muscle tone (hypotonia) in the trunk.  About 40 percent of people with Aicardi-Goutieres syndrome have painful, itchy skin lesions, usually on the fingers, toes, and ears. These puffy, red lesions, which are called chilblains, are caused by inflammation of small blood vessels. They may be brought on or made worse by exposure to cold. Vision problems, joint stiffness, and mouth ulcers may also occur in this disorder.  As a result of the severe neurological problems usually associated with Aicardi-Goutieres syndrome, most people with this disorder do not survive past childhood. However, some affected individuals who have later onset and milder neurological problems may live into adulthood.
How many people are affected by Aicardi-Goutieres syndrome ? 

Aicardi-Goutieres syndrome is a rare disorder. Its exact prevalence is unknown.
What are the genetic changes related to Aicardi-Goutieres syndrome ? 

Mutations in the TREX1, RNASEH2A, RNASEH2B, RNASEH2C, and SAMHD1 genes have been identified in people with Aicardi-Goutieres syndrome.  The TREX1, RNASEH2A, RNASEH2B, and RNASEH2C genes provide instructions for making nucleases, which are enzymes that help break up molecules of DNA and its chemical cousin RNA. Mutations in any of these genes are believed to result in an absent or dysfunctional nuclease enzyme. Researchers suggest that absent or impaired enzyme function may result in the accumulation of unneeded DNA and RNA in cells. These DNA and RNA molecules or fragments may be generated during the first stage of protein production (transcription), copying (replication) of cells' genetic material in preparation for cell division, DNA repair, cell death, and other processes. The unneeded DNA and RNA may be mistaken by cells for that of viral invaders, triggering immune system reactions that result in encephalopathy, skin lesions, and other signs and symptoms of Aicardi-Goutieres syndrome.  The SAMHD1 gene provides instructions for making a protein whose function is not well understood; however, it is believed to be involved in the immune system and the inflammatory process. Mutations in this gene likely result in a protein that does not function properly, resulting in immune system abnormalities, inflammatory damage to the brain and skin, and other characteristics of Aicardi-Goutieres syndrome.
Is Aicardi-Goutieres syndrome inherited ? 

Aicardi-Goutieres syndrome can have different inheritance patterns. In most cases it 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.  Rarely, 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. These cases result from new mutations in the gene and occur in people with no history of the disorder in their family.

What is (are) microcephaly-capillary malformation syndrome ? 

Microcephaly-capillary malformation syndrome is an inherited disorder characterized by an abnormally small head size (microcephaly) and abnormalities of small blood vessels in the skin called capillaries (capillary malformations).  In people with microcephaly-capillary malformation syndrome, microcephaly begins before birth and is associated with an unusually small brain and multiple brain abnormalities. Affected individuals develop seizures that can occur many times per day and are difficult to treat (intractable epilepsy). The problems with brain development and epilepsy lead to profound developmental delay and intellectual impairment. Most affected individuals do not develop skills beyond those of a 1- or 2-month-old infant. For example, most children with this condition are never able to control their head movements or sit unassisted.  Capillary malformations are composed of enlarged capillaries that increase blood flow near the surface of the skin. These malformations look like pink or red spots on the skin. People with microcephaly-capillary malformation syndrome are born with anywhere from a few to hundreds of these spots, which can occur anywhere on the body. The spots are usually round or oval-shaped and range in size from the head of a pin to a large coin.  Other signs and symptoms of microcephaly-capillary malformation syndrome include abnormal movements, feeding difficulties, slow growth, and short stature. Most affected individuals have abnormalities of the fingers and toes, including digits with tapered ends and abnormally small or missing fingernails and toenails. Some affected children also have distinctive facial features and an unusual pattern of hair growth on the scalp.
How many people are affected by microcephaly-capillary malformation syndrome ? 

Microcephaly-capillary malformation syndrome is rare. About a dozen people have been diagnosed with the disorder.
What are the genetic changes related to microcephaly-capillary malformation syndrome ? 

Microcephaly-capillary malformation syndrome results from mutations in the STAMBP gene. This gene provides instructions for making a protein called STAM binding protein. This protein plays a role in sorting damaged or unneeded proteins so they can be transported from the cell surface to specialized cell compartments that break down (degrade) or recycle them. This process helps to maintain the proper balance of protein production and breakdown (protein homeostasis) that cells need to function and survive. Studies suggest that STAM binding protein is also involved in multiple chemical signaling pathways within cells, including pathways needed for overall growth and the formation of new blood vessels (angiogenesis).  Mutations in the STAMBP gene reduce or eliminate the production of STAM binding protein. This shortage allows damaged or unneeded proteins to build up inside cells instead of being degraded or recycled, which may damage cells and cause them to self-destruct (undergo apoptosis). Researchers suspect that abnormal apoptosis of brain cells starting before birth may cause microcephaly and the underlying brain abnormalities found in people with microcephaly-capillary malformation syndrome. A lack of STAM binding protein also alters multiple signaling pathways that are necessary for normal development, which may underlie the capillary malformations and other signs and symptoms of the condition.
Is microcephaly-capillary malformation syndrome inherited ? 

This condition has an autosomal recessive pattern of inheritance, which means both copies of the STAMBP gene in each cell have mutations. An affected individual usually inherits one altered copy of the gene from each parent. Parents of an individual with an autosomal recessive condition typically do not show signs and symptoms of the condition.  At least one individual with microcephaly-capillary malformation syndrome inherited two mutated copies of the STAMBP gene through a mechanism called uniparental isodisomy. In this case, an error occurred during the formation of egg or sperm cells, and the child received two copies of the mutated gene from one parent instead of one copy from each parent.

What is (are) atopic dermatitis ? 

Atopic dermatitis (also known as atopic eczema) is a disorder characterized by inflammation of the skin (dermatitis). The condition usually begins in early infancy, and it often disappears before adolescence. However, in some affected individuals the condition continues into adulthood or does not begin until adulthood. Hallmarks of atopic dermatitis include dry, itchy skin and red rashes that can come and go. The rashes can occur on any part of the body, although the pattern tends to be different at different ages. In affected infants, the rashes commonly occur on the face, scalp, hands, and feet. In children, the rashes are usually found in the bend of the elbows and knees and on the front of the neck. In adolescents and adults, the rashes typically occur on the wrists, ankles, and eyelids in addition to the bend of the elbows and knees. Scratching the itchy skin can lead to oozing and crusting of the rashes and thickening and hardening (lichenification) of the skin. The itchiness can be so severe as to disturb sleep and impair a person's quality of life.  The word "atopic" indicates an association with allergies. While atopic dermatitis is not always due to an allergic reaction, it is commonly associated with other allergic disorders: up to 60 percent of people with atopic dermatitis develop asthma or hay fever (allergic rhinitis) later in life, and up to 30 percent have food allergies. Atopic dermatitis is often the beginning of a series of allergic disorders, referred to as the atopic march. Development of these disorders typically follows a pattern, beginning with atopic dermatitis, followed by food allergies, then hay fever, and finally asthma. However, not all individuals with atopic dermatitis will progress through the atopic march, and not all individuals with one allergic disease will develop others.  Individuals with atopic dermatitis have an increased risk of developing other conditions related to inflammation, such as inflammatory bowel disease and rheumatoid arthritis. They are also more likely than individuals of the general public to have a behavioral or psychiatric disorder, such as attention deficit hyperactivity disorder (ADHD) or depression.
How many people are affected by atopic dermatitis ? 

Atopic dermatitis is a common disorder that affects 10 to 20 percent of children and 5 to 10 percent of adults.
