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:  How many people are affected by mal de Meleda ?
Answer: Mal de Meleda is a rare disorder; its prevalence is unknown. The disorder was first identified on the Croatian island of Mjlet (called Meleda in Italian) and has since been found in populations worldwide.
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:  Is mal de Meleda 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 hypobetalipoproteinemia ?
Answer: Familial hypobetalipoproteinemia (FHBL) is a disorder that impairs the body's ability to absorb and transport fats. This condition is characterized by low levels of a fat-like substance called cholesterol in the blood. The severity of signs and symptoms experienced by people with FHBL vary widely. The most mildly affected individuals have few problems with absorbing fats from the diet and no related signs and symptoms. Many individuals with FHBL develop an abnormal buildup of fats in the liver called hepatic steatosis or fatty liver. In more severely affected individuals, fatty liver may progress to chronic liver disease (cirrhosis). Individuals with severe FHBL have greater difficulty absorbing fats as well as fat-soluble vitamins such as vitamin E and vitamin A. This difficulty in fat absorption leads to excess fat in the feces (steatorrhea). In childhood, these digestive problems can result in an inability to grow or gain weight at the expected rate (failure to thrive).
Question:  How many people are affected by familial hypobetalipoproteinemia ?
Answer: FHBL is estimated to occur in 1 in 1,000 to 3,000 individuals.
Question:  What are the genetic changes related to familial hypobetalipoproteinemia ?
Answer: Most cases of FHBL are caused by mutations in the APOB gene. This gene provides instructions for making two versions of the apolipoprotein B protein: a short version called apolipoprotein B-48 and a longer version known as apolipoprotein B-100. Both of these proteins are components of lipoproteins, which transport fats and cholesterol in the blood.  Most APOB gene mutations that lead to FHBL cause both versions of apolipoprotein B to be abnormally short. The severity of the condition largely depends on the length of these two versions of apolipoprotein B. Severely shortened versions cannot partner with lipoproteins and transport fats and cholesterol. Proteins that are only slightly shortened retain some function but partner less effectively with lipoproteins. Generally, the signs and symptoms of FHBL are worse if both versions of apolipoprotein B are severely shortened. Mild or no signs and symptoms result when the proteins are only slightly shortened. All of these protein changes lead to a reduction of functional apolipoprotein B. As a result, the transportation of dietary fats and cholesterol is decreased or absent. A decrease in fat transport reduces the body's ability to absorb fats and fat-soluble vitamins from the diet.  Although APOB gene mutations are responsible for most cases of FHBL, mutations in a few other genes account for a small number of cases. Some people with FHBL do not have identified mutations in any of these genes. Changes in other, unidentified genes are likely involved in this condition.
Question:  Is familial hypobetalipoproteinemia inherited ?
Answer: This condition is inherited in an autosomal codominant pattern. Codominance means that copies of the gene from both parents are active (expressed), and both copies influence the genetic trait. In FHBL, a change in one copy of the APOB gene in each cell can cause the condition, but changes in both copies of the gene cause more severe health problems.

Question:  What is (are) guanidinoacetate methyltransferase deficiency ?
Answer: Guanidinoacetate methyltransferase deficiency is an inherited disorder that primarily affects the brain and muscles. Without early treatment, people with this disorder have neurological problems that are usually severe. These problems include intellectual disability, speech development limited to a few words, and recurrent seizures (epilepsy). Affected individuals may also exhibit autistic behaviors that affect communication and social interaction or self-injurious behaviors such as head-banging. Other features of this disorder can include involuntary movements (extrapyramidal dysfunction) such as tremors or facial tics.  People with guanidinoacetate methyltransferase deficiency may have weak muscle tone and delayed development of motor skills such as sitting or walking. In severe cases they may lose previously acquired skills such as the ability to support their head or to sit unsupported.
Question:  How many people are affected by guanidinoacetate methyltransferase deficiency ?
Answer: Guanidinoacetate methyltransferase deficiency is a very rare disorder. About 80 affected individuals have been described in the medical literature. Of these, approximately one-third are of Portuguese origin.
Question:  What are the genetic changes related to guanidinoacetate methyltransferase deficiency ?
Answer: Mutations in the GAMT gene cause guanidinoacetate methyltransferase deficiency. The GAMT gene provides instructions for making the enzyme guanidinoacetate methyltransferase. This enzyme participates in the two-step production (synthesis) of the compound creatine from the protein building blocks (amino acids) glycine, arginine, and methionine. Specifically, guanidinoacetate methyltransferase controls the second step of this process. In this step, creatine is produced from another compound called guanidinoacetate. Creatine is needed for the body to store and use energy properly.  GAMT gene mutations impair the ability of the guanidinoacetate methyltransferase enzyme to participate in creatine synthesis, resulting in a shortage of creatine. The effects of guanidinoacetate methyltransferase deficiency are most severe in organs and tissues that require large amounts of energy, especially the brain.
Question:  Is guanidinoacetate methyltransferase 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) 3-methylcrotonyl-CoA carboxylase deficiency ?
Answer: 3-methylcrotonyl-CoA carboxylase deficiency (also known as 3-MCC deficiency) is an inherited disorder in which the body is unable to process certain proteins properly. People with this disorder have a shortage of an enzyme that helps break down proteins containing a particular building block (amino acid) called leucine.  Infants with 3-MCC deficiency appear normal at birth but usually develop signs and symptoms in infancy or early childhood. The characteristic features of this condition, which can range from mild to life-threatening, include feeding difficulties, recurrent episodes of vomiting and diarrhea, excessive tiredness (lethargy), and weak muscle tone (hypotonia). If untreated, this disorder can lead to delayed development, seizures, and coma. Many of these complications can be prevented with early detection and lifelong management with a low-protein diet and appropriate supplements. Some people with gene mutations that cause 3-MCC deficiency never experience any signs or symptoms of the condition.  The characteristic features of 3-MCC deficiency are similar to those of Reye syndrome, a severe disorder that develops in children while they appear to be recovering from viral infections such as chicken pox or flu. Most cases of Reye syndrome are associated with the use of aspirin during these viral infections.
Question:  How many people are affected by 3-methylcrotonyl-CoA carboxylase deficiency ?
Answer: This condition is detected in an estimated 1 in 36,000 newborns worldwide.
Question:  What are the genetic changes related to 3-methylcrotonyl-CoA carboxylase deficiency ?
Answer: Mutations in the MCCC1 or MCCC2 gene can cause 3-MCC deficiency. These two genes provide instructions for making different parts (subunits) of an enzyme called 3-methylcrotonyl-coenzyme A carboxylase (3-MCC). This enzyme plays a critical role in breaking down proteins obtained from the diet. Specifically, 3-MCC is responsible for the fourth step in processing leucine, an amino acid that is part of many proteins.  Mutations in the MCCC1 or MCCC2 gene reduce or eliminate the activity of 3-MCC, preventing the body from processing leucine properly. As a result, toxic byproducts of leucine processing build up to harmful levels, which can damage the brain. This damage underlies the signs and symptoms of 3-MCC deficiency.
Question:  Is 3-methylcrotonyl-CoA carboxylase 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) multiple epiphyseal dysplasia ?
Answer: Multiple epiphyseal dysplasia is a disorder of cartilage and bone development primarily affecting the ends of the long bones in the arms and legs (epiphyses). There are two types of multiple epiphyseal dysplasia, which can be distinguished by their pattern of inheritance. Both the dominant and recessive types have relatively mild signs and symptoms, including joint pain that most commonly affects the hips and knees, early-onset arthritis, and a waddling walk. Although some people with multiple epiphyseal dysplasia have mild short stature as adults, most are of normal height. The majority of individuals are diagnosed during childhood; however, some mild cases may not be diagnosed until adulthood.  Recessive multiple epiphyseal dysplasia is distinguished from the dominant type by malformations of the hands, feet, and knees and abnormal curvature of the spine (scoliosis). About 50 percent of individuals with recessive multiple epiphyseal dysplasia are born with at least one abnormal feature, including an inward- and upward-turning foot (clubfoot), an opening in the roof of the mouth (cleft palate), an unusual curving of the fingers or toes (clinodactyly), or ear swelling. An abnormality of the kneecap called a double-layered patella is also relatively common.
Question:  How many people are affected by multiple epiphyseal dysplasia ?
Answer: The incidence of dominant multiple epiphyseal dysplasia is estimated to be at least 1 in 10,000 newborns. The incidence of recessive multiple epiphyseal dysplasia is unknown. Both forms of this disorder may actually be more common because some people with mild symptoms are never diagnosed.
Question:  What are the genetic changes related to multiple epiphyseal dysplasia ?
Answer: Mutations in the COMP, COL9A1, COL9A2, COL9A3, or MATN3 gene can cause dominant multiple epiphyseal dysplasia. These genes provide instructions for making proteins that are found in the spaces between cartilage-forming cells (chondrocytes). These proteins interact with each other and play an important role in cartilage and bone formation. 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.  The majority of individuals with dominant multiple epiphyseal dysplasia have mutations in the COMP gene. About 10 percent of affected individuals have mutations in the MATN3 gene. Mutations in the COMP or MATN3 gene prevent the release of the proteins produced from these genes into the spaces between the chondrocytes. The absence of these proteins leads to the formation of abnormal cartilage, which can cause the skeletal problems characteristic of dominant multiple epiphyseal dysplasia.  The COL9A1, COL9A2, and COL9A3 genes provide instructions for making a protein called type IX collagen. Collagens are a family of proteins that strengthen and support connective tissues, such as skin, bone, cartilage, tendons, and ligaments. Mutations in the COL9A1, COL9A2, or COL9A3 gene are found in less than five percent of individuals with dominant multiple epiphyseal dysplasia. It is not known how mutations in these genes cause the signs and symptoms of this disorder. Research suggests that mutations in these genes may cause type IX collagen to accumulate inside the cell or interact abnormally with other cartilage components.  Some people with dominant multiple epiphyseal dysplasia do not have a mutation in the COMP, COL9A1, COL9A2, COL9A3, or MATN3 gene. In these cases, the cause of the condition is unknown.  Mutations in the SLC26A2 gene cause recessive multiple epiphyseal dysplasia. This gene provides instructions for making a protein that is essential for the normal development of cartilage and for its conversion to bone. Mutations in the SLC26A2 gene alter the structure of developing cartilage, preventing bones from forming properly and resulting in the skeletal problems characteristic of recessive multiple epiphyseal dysplasia.
Question:  Is multiple epiphyseal dysplasia inherited ?
Answer: Multiple epiphyseal dysplasia can have different inheritance patterns.  This condition 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 may result from new mutations in the gene. These cases occur in people with no history of the disorder in their family.  Multiple epiphyseal dysplasia can also be inherited in an autosomal recessive pattern, which means both copies of the gene in each cell have mutations. Most often, the parents of an individual with an autosomal recessive condition each carry one copy of the mutated gene, but do not show signs and symptoms of the condition.

Question:  What is (are) autosomal dominant partial epilepsy with auditory features ?
Answer: Autosomal dominant partial epilepsy with auditory features (ADPEAF) is an uncommon form of epilepsy that runs in families. This disorder causes seizures usually characterized by sound-related (auditory) symptoms such as buzzing, humming, or ringing. Some people experience more complex sounds during a seizure, such as specific voices or music, or changes in the volume of sounds. Some people with ADPEAF suddenly become unable to understand language before losing consciousness during a seizure. This inability to understand speech is known as receptive aphasia. Less commonly, seizures may cause visual hallucinations, a disturbance in the sense of smell, a feeling of dizziness or spinning (vertigo), or other symptoms affecting the senses.  Seizures associated with ADPEAF usually begin in adolescence or young adulthood. They may be triggered by specific sounds, such as a ringing telephone or speech, but in most cases the seizures do not have any recognized triggers. In most affected people, seizures are infrequent and effectively controlled with medication.  Most people with ADPEAF have seizures described as simple partial seizures, which do not cause a loss of consciousness. These seizures are thought to begin in a part of the brain called the lateral temporal lobe. In some people, seizure activity may spread from the lateral temporal lobe to affect other regions of the brain. If seizure activity spreads to affect the entire brain, it causes a loss of consciousness, muscle stiffening, and rhythmic jerking. Episodes that begin as partial seizures and spread throughout the brain are known as secondarily generalized seizures.
Question:  How many people are affected by autosomal dominant partial epilepsy with auditory features ?
Answer: This condition appears to be uncommon, although its prevalence is unknown.
Question:  What are the genetic changes related to autosomal dominant partial epilepsy with auditory features ?
Answer: Mutations in the LGI1 gene cause ADPEAF. This gene provides instructions for making a protein called Lgi1 or epitempin, which is found primarily in nerve cells (neurons) in the brain. Although researchers have proposed several functions for this protein, its precise role in the brain remains uncertain.  Mutations in the LGI1 gene likely disrupt the function of epitempin. It is unclear how the altered protein leads to seizure activity in the brain.  LGI1 mutations have been identified in about half of all families diagnosed with ADPEAF. In the remaining families, the cause of the condition is unknown. Researchers are searching for other genetic changes that may underlie the condition.
Question:  Is autosomal dominant partial epilepsy with auditory features inherited ?
Answer: This condition is inherited in an autosomal dominant pattern, which means one copy of the altered LGI1 gene in each cell is sufficient to raise the risk of developing epilepsy. About two-thirds of people who inherit a mutation in this gene will develop seizures. In most cases, an affected person has one affected parent and other relatives with the condition.
