Question:
What are the genetic changes related to autosomal dominant nocturnal frontal lobe epilepsy ?

Answer:
Mutations in the CHRNA2, CHRNA4, and CHRNB2 genes can cause ADNFLE. These genes provide instructions for making different parts (subunits) of a larger molecule called a neuronal nicotinic acetylcholine receptor (nAChR). This receptor plays an important role in chemical signaling between nerve cells (neurons) in the brain.  Communication between neurons depends on chemicals called neurotransmitters, which are released from one neuron and taken up by neighboring neurons. Researchers believe that mutations in the CHRNA2, CHRNA4, and CHRNB2 genes affect the normal release and uptake of certain neurotransmitters in the brain. The resulting changes in signaling between neurons likely trigger the abnormal brain activity associated with seizures.  The seizures associated with ADNFLE begin in areas of the brain called the frontal lobes. These regions of the brain are involved in many critical functions, including reasoning, planning, judgment, and problem-solving. It is unclear why mutations in the CHRNA2, CHRNA4, and CHRNB2 genes cause seizures in the frontal lobes rather than elsewhere in the brain. Researchers are also working to determine why these seizures occur most often during sleep.  The genetic cause of ADNFLE has been identified in only a small percentage of affected families. In some cases, a gene other than those that make up the nAChR are involved. In the remaining families, the cause of the condition is unknown. Researchers are searching for other genetic changes, including mutations in other subunits of nAChR, that may underlie the condition.
Question:
Is autosomal dominant nocturnal frontal lobe epilepsy 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 raise the risk of developing epilepsy. About 70 percent of people who inherit a mutation in the CHRNA2, CHRNA4, or CHRNB2 gene will develop seizures. In most cases, an affected person has one affected parent and other relatives with the condition. Other cases are described as sporadic, which means an affected person has no family history of the disorder.

Question:
What is (are) multiple familial trichoepithelioma ?

Answer:
Multiple familial trichoepithelioma is a condition involving multiple skin tumors that develop from structures associated with the skin (skin appendages), such as hair follicles and sweat glands. People with multiple familial trichoepithelioma typically develop large numbers of smooth, round tumors called trichoepitheliomas, which arise from hair follicles. Trichoepitheliomas are generally noncancerous (benign) but occasionally develop into a type of skin cancer called basal cell carcinoma.  Individuals with multiple familial trichoepithelioma occasionally also develop other types of tumors, including growths called spiradenomas and cylindromas. Spiradenomas develop in sweat glands. The origin of cylindromas has been unclear; while previously thought to derive from sweat glands, they are now generally believed to begin in hair follicles. Affected individuals are also at increased risk of developing tumors in tissues other than skin appendages, particularly benign or malignant tumors of the salivary glands.  People with multiple familial trichoepithelioma typically begin developing tumors during childhood or adolescence. The tumors mostly appear on the face, especially in the folds in the skin between the nose and lips (nasolabial folds, sometimes called smile lines), but may also occur on the neck, scalp, or trunk. They may grow larger and increase in number over time.  In severe cases, the tumors may get in the way of the eyes, ears, nose, or mouth and affect vision, hearing, or other functions. The growths can be disfiguring and may contribute to depression or other psychological problems. For reasons that are unclear, females with multiple familial trichoepithelioma are often more severely affected than males.
Question:
How many people are affected by multiple familial trichoepithelioma ?

Answer:
Multiple familial trichoepithelioma is a rare disorder; its prevalence is unknown.
Question:
What are the genetic changes related to multiple familial trichoepithelioma ?

Answer:
Multiple familial trichoepithelioma can be caused by mutations in the CYLD gene. This gene provides instructions for making a protein that helps regulate nuclear factor-kappa-B. Nuclear factor-kappa-B is a group of related proteins that help protect cells from self-destruction (apoptosis) in response to certain signals. In regulating the action of nuclear factor-kappa-B, the CYLD protein allows cells to respond properly to signals to self-destruct when appropriate, such as when the cells become abnormal. By this mechanism, the CYLD protein acts as a tumor suppressor, which means that it helps prevent cells from growing and dividing too fast or in an uncontrolled way.  People with CYLD-related multiple familial trichoepithelioma are born with a mutation in one of the two copies of the CYLD gene in each cell. This mutation prevents the cell from making functional CYLD protein from the altered copy of the gene. However, enough protein is usually produced from the other, normal copy of the gene to regulate cell growth effectively. For tumors to develop, a second mutation or deletion of genetic material involving the other copy of the CYLD gene must occur in certain cells during a person's lifetime.  When both copies of the CYLD gene are mutated in a particular cell, that cell cannot produce any functional CYLD protein. The loss of this protein allows the cell to grow and divide in an uncontrolled way to form a tumor. In people with multiple familial trichoepithelioma, a second CYLD mutation typically occurs in multiple cells over an affected person's lifetime. The loss of CYLD protein in these cells leads to the growth of skin appendage tumors.  Some researchers consider multiple familial trichoepithelioma and two related conditions called familial cylindromatosis and Brooke-Spiegler syndrome, which are also caused by CYLD gene mutations, to be different forms of the same disorder. It is unclear why mutations in the CYLD gene cause different patterns of skin appendage tumors in each of these conditions, or why the tumors are generally confined to the skin in these disorders.  Some people with multiple familial trichoepithelioma do not have mutations in the CYLD gene. Scientists are working to identify the genetic cause of the disorder in these individuals.
Question:
Is multiple familial trichoepithelioma inherited ?

Answer:
Susceptibility to multiple familial trichoepithelioma has an autosomal dominant pattern of inheritance, which means one copy of the altered gene in each cell increases the risk of developing this condition. However, a second, non-inherited mutation is required for development of skin appendage tumors in this disorder.

Question:
What is (are) congenital deafness with labyrinthine aplasia, microtia, and microdontia ?

Answer:
Congenital deafness with labyrinthine aplasia, microtia, and microdontia (also called LAMM syndrome) is a condition that affects development of the ears and teeth. In people with this condition, the structures that form the inner ear are usually completely absent (labyrinthine aplasia). Rarely, affected individuals have some underdeveloped inner ear structures in one or both ears. The abnormalities of the inner ear cause a form of hearing loss called sensorineural deafness that is present from birth (congenital). Because the inner ear is important for balance as well as hearing, development of motor skills, such as sitting and crawling, may be delayed in affected infants. In addition, people with LAMM syndrome often have abnormally small outer ears (microtia) with narrow ear canals. They can also have unusually small, widely spaced teeth (microdontia).
Question:
How many people are affected by congenital deafness with labyrinthine aplasia, microtia, and microdontia ?

Answer:
LAMM syndrome is a rare condition, although its prevalence is unknown. Approximately a dozen affected families have been identified.
Question:
What are the genetic changes related to congenital deafness with labyrinthine aplasia, microtia, and microdontia ?

Answer:
LAMM syndrome is caused by mutations in the FGF3 gene, which provides instructions for making a protein called fibroblast growth factor 3 (FGF3). By attaching to another protein known as a receptor, the FGF3 protein triggers a cascade of chemical reactions inside the cell that signal the cell to undergo certain changes, such as dividing or maturing to take on specialized functions. During development before birth, the signals triggered by the FGF3 protein stimulate cells to form the structures that make up the inner ears. The FGF3 protein is also involved in the development of many other organs and structures, including the outer ears and teeth.  FGF3 gene mutations involved in LAMM syndrome alter the FGF3 protein. The altered protein likely has reduced or absent function and is unable to stimulate signaling. The loss of FGF3 function impairs development of the ears and teeth, which leads to the characteristic features of LAMM syndrome.
Question:
Is congenital deafness with labyrinthine aplasia, microtia, and microdontia 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) FOXG1 syndrome ?

Answer:
FOXG1 syndrome is a condition characterized by impaired development and structural brain abnormalities. Affected infants are small at birth, and their heads grow more slowly than normal, leading to an unusually small head size (microcephaly) by early childhood. The condition is associated with a particular pattern of brain malformations that includes a thin or underdeveloped connection between the right and left halves of the brain (a structure called the corpus callosum), reduced folds and grooves (gyri) on the surface of the brain, and a smaller than usual amount of brain tissue known as white matter.  FOXG1 syndrome affects most aspects of development, and children with the condition typically have severe intellectual disability. Abnormal or involuntary movements, such as jerking movements of the arms and legs and repeated hand motions, are common, and most affected children do not learn to sit or walk without assistance. Babies and young children with FOXG1 syndrome often have feeding problems, sleep disturbances, seizures, irritability, and excessive crying. The condition is also characterized by limited communication and social interaction, including poor eye contact and a near absence of speech and language skills. Because of these social impairments, FOXG1 syndrome is classified as an autism spectrum disorder.  FOXG1 syndrome was previously described as a congenital variant of Rett syndrome, which is a similar disorder of brain development. Both disorders are characterized by impaired development, intellectual disability, and problems with communication and language. However, Rett syndrome is diagnosed almost exclusively in females, while FOXG1 syndrome affects both males and females. Rett syndrome also involves a period of apparently normal early development that does not occur in FOXG1 syndrome. Because of these differences, physicians and researchers now usually consider FOXG1 syndrome to be distinct from Rett syndrome.
Question:
How many people are affected by FOXG1 syndrome ?

Answer:
FOXG1 syndrome appears to be rare. At least 30 affected individuals have been described in the medical literature.
Question:
What are the genetic changes related to FOXG1 syndrome ?

Answer:
As its name suggests, FOXG1 syndrome is caused by changes involving the FOXG1 gene. This gene provides instructions for making a protein called forkhead box G1. This protein plays an important role in brain development before birth, particularly in a region of the embryonic brain known as the telencephalon. The telencephalon ultimately develops into several critical structures, including the the largest part of the brain (the cerebrum), which controls most voluntary activity, language, sensory perception, learning, and memory.  In some cases, FOXG1 syndrome is caused by mutations within the FOXG1 gene itself. In others, the condition results from a deletion of genetic material from a region of the long (q) arm of chromosome 14 that includes the FOXG1 gene. All of these genetic changes prevent the production of forkhead box G1 or impair the protein's function. A shortage of functional forkhead box G1 disrupts normal brain development starting before birth, which appears to underlie the structural brain abnormalities and severe developmental problems characteristic of FOXG1 syndrome.
Question:
Is FOXG1 syndrome inherited ?

Answer:
FOXG1 syndrome is considered an autosomal dominant condition, which means one copy of the altered gene in each cell is sufficient to cause the disorder. All reported cases have resulted from new mutations or deletions involving the FOXG1 gene and have occurred in people with no history of the disorder in their family. Because the condition is so severe, no one with FOXG1 syndrome has been known to have children.

Question:
What is (are) pilomatricoma ?

Answer:
Pilomatricoma, also known as pilomatrixoma, is a type of noncancerous (benign) skin tumor associated with hair follicles. Hair follicles are specialized structures in the skin where hair growth occurs. Pilomatricomas occur most often on the head or neck, although they can also be found on the arms, torso, or legs. A pilomatricoma feels like a small, hard lump under the skin. This type of tumor grows relatively slowly and usually does not cause pain or other symptoms. Most affected individuals have a single tumor, although rarely multiple pilomatricomas can occur. If a pilomatricoma is removed surgically, it tends not to grow back (recur).  Most pilomatricomas occur in people under the age of 20. However, these tumors can also appear later in life. Almost all pilomatricomas are benign, but a very small percentage are cancerous (malignant). Unlike the benign form, the malignant version of this tumor (known as a pilomatrix carcinoma) occurs most often in middle age or late in life.  Pilomatricoma usually occurs without other signs or symptoms (isolated), but this type of tumor has also rarely been reported with inherited conditions. Disorders that can be associated with pilomatricoma include Gardner syndrome, which is characterized by multiple growths (polyps) and cancers of the colon and rectum; myotonic dystrophy, which is a form of muscular dystrophy; and Rubinstein-Taybi syndrome, which is a condition that affects many parts of the body and is associated with an increased risk of both benign and malignant tumors.
Question:
How many people are affected by pilomatricoma ?

Answer:
Pilomatricoma is an uncommon tumor. The exact prevalence is unknown, but pilomatricoma probably accounts for less than 1 percent of all benign skin tumors.
Question:
What are the genetic changes related to pilomatricoma ?

Answer:
Mutations in the CTNNB1 gene are found in almost all cases of isolated pilomatricoma. These mutations are somatic, which means they are acquired during a person's lifetime and are present only in tumor cells. Somatic mutations are not inherited.  The CTNNB1 gene provides instructions for making a protein called beta-catenin. This protein plays an important role in sticking cells together (cell adhesion) and in communication between cells. It is also involved in cell signaling as part of the WNT signaling pathway. This pathway promotes the growth and division (proliferation) of cells and helps determine the specialized functions a cell will have (differentiation). WNT signaling is involved in many aspects of development before birth, as well as the maintenance and repair of adult tissues.  Among its many activities, beta-catenin appears to be necessary for the normal function of hair follicles. This protein is active in cells that make up a part of the hair follicle known as the matrix. These cells divide and mature to form the different components of the hair follicle and the hair shaft. As matrix cells divide, the hair shaft is pushed upward and extends beyond the skin.  Mutations in the CTNNB1 gene lead to a version of beta-catenin that is always turned on (constitutively active). The overactive protein triggers matrix cells to divide too quickly and in an uncontrolled way, leading to the formation of a pilomatricoma.  Most pilomatrix carcinomas, the malignant version of pilomatricoma, also have somatic mutations in the CTNNB1 gene. It is unclear why some pilomatricomas are cancerous but most others are not.
Question:
Is pilomatricoma inherited ?

Answer:
Most people with isolated pilomatricoma do not have any other affected family members. However, rare families with multiple affected members have been reported. In these cases, the inheritance pattern of the condition (if any) is unknown.

Question:
What is (are) spastic paraplegia type 4 ?

Answer:
Spastic paraplegia type 4 is part of a group of genetic disorders known as hereditary spastic paraplegias. These disorders are characterized by progressive muscle stiffness (spasticity) and the development of paralysis of the lower limbs (paraplegia). Hereditary spastic paraplegias are divided into two types: pure and complex. The pure types involve only the lower limbs, whereas the complex types also involve the upper limbs (to a lesser degree) and the nervous system. Spastic paraplegia type 4 is a pure hereditary spastic paraplegia.  Like all hereditary spastic paraplegias, spastic paraplegia type 4 involves spasticity of the leg muscles and muscle weakness. People with this condition can also experience exaggerated reflexes (hyperreflexia), ankle spasms, high-arched feet (pes cavus), and reduced bladder control. Spastic paraplegia type 4 generally affects nerve and muscle function in the lower half of the body only.
Question:
How many people are affected by spastic paraplegia type 4 ?

Answer:
The prevalence of spastic paraplegia type 4 is estimated to be 2 to 6 in 100,000 people worldwide.
Question:
What are the genetic changes related to spastic paraplegia type 4 ?

Answer:
Mutations in the SPAST gene cause spastic paraplegia type 4. The SPAST gene provides instructions for producing a protein called spastin. Spastin is found throughout the body, particularly in certain nerve cells (neurons). The spastin protein plays a role in the function of microtubules, which are rigid, hollow fibers that make up the cell's structural framework (the cytoskeleton). Microtubules are also involved in transporting cell components and facilitating cell division. Spastin likely helps restrict microtubule length and disassemble microtubule structures when they are no longer needed. Mutations in spastin impair the microtubules' ability to transport cell components, especially in nerve cells; researchers believe this contributes to the major signs and symptoms of spastic paraplegia type 4.
Question:
Is spastic paraplegia type 4 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 inherits the mutation from one affected parent. The remaining cases may result from new mutations in the gene. These cases occur in people with no history of the disorder in their family.

Question:
What is (are) hepatic veno-occlusive disease with immunodeficiency ?

Answer:
Hepatic veno-occlusive disease with immunodeficiency (also called VODI) is a hereditary disorder of the liver and immune system. Its signs and symptoms appear after the first few months of life.  Hepatic veno-occlusive disease is a condition that blocks (occludes) small veins in the liver, disrupting blood flow in this organ. This condition can lead to enlargement of the liver (hepatomegaly), a buildup of scar tissue (hepatic fibrosis), and liver failure.  Children with VODI are prone to recurrent infections caused by certain bacteria, viruses, and fungi. The organisms that cause infection in people with this disorder are described as opportunistic because they ordinarily do not cause illness in healthy people. These infections are usually serious and may be life-threatening. In most people with VODI, infections occur before hepatic veno-occlusive disease becomes evident.  Many people with VODI live only into childhood, although some affected individuals have lived to early adulthood.
