Topic: myofibrillar myopathy
Question: What is (are) myofibrillar myopathy ?
Answer: Myofibrillar myopathy is part of a group of disorders called muscular dystrophies that affect muscle function and cause weakness. Myofibrillar myopathy primarily affects skeletal muscles, which are muscles that the body uses for movement. In some cases, the heart (cardiac) muscle is also affected.  The signs and symptoms of myofibrillar myopathy vary widely among affected individuals, typically depending on the condition's genetic cause. Most people with this disorder begin to develop muscle weakness (myopathy) in mid-adulthood. However, features of this condition can appear anytime between infancy and late adulthood. Muscle weakness most often begins in the hands and feet (distal muscles), but some people first experience weakness in the muscles near the center of the body (proximal muscles). Other affected individuals develop muscle weakness throughout their body. Facial muscle weakness can cause swallowing and speech difficulties. Muscle weakness worsens over time.  Other signs and symptoms of myofibrillar myopathy can include a weakened heart muscle (cardiomyopathy), muscle pain (myalgia), loss of sensation and weakness in the limbs (peripheral neuropathy), and respiratory failure. Individuals with this condition may have skeletal problems including joint stiffness (contractures) and abnormal side-to-side curvature of the spine (scoliosis). Rarely, people with this condition develop clouding of the lens of the eyes (cataracts).

Question: What are the genetic changes related to myofibrillar myopathy ?
Answer: Mutations in several genes can cause myofibrillar myopathy. These genes provide instructions for making proteins that play important roles in muscle fibers. Within muscle fibers, these proteins are involved in the assembly of structures called sarcomeres. Sarcomeres are necessary for muscles to tense (contract). The proteins associated with myofibrillar myopathy are normally active on rod-like structures within the sarcomere called Z-discs. Z-discs link neighboring sarcomeres together to form myofibrils, the basic unit of muscle fibers. The linking of sarcomeres and formation of myofibrils provide strength for muscle fibers during repeated muscle contraction and relaxation.  Gene mutations that cause myofibrillar myopathy disrupt the function of skeletal and cardiac muscle. Various muscle proteins form clumps (aggregates) in the muscle fibers of affected individuals. The aggregates prevent these proteins from functioning normally, which reduces linking between neighboring sarcomeres. As a result, muscle fiber strength is diminished.  At least six genes have been associated with myofibrillar myopathy. Mutations in these six genes account for approximately half of all cases of this condition. Mutations in the DES, MYOT, and LDB3 genes are responsible for the majority of cases of myofibrillar myopathy when the genetic cause is known.

Topic: 2-methylbutyryl-CoA dehydrogenase deficiency
Question: What is (are) 2-methylbutyryl-CoA dehydrogenase deficiency ?
Answer: 2-methylbutyryl-CoA dehydrogenase deficiency is a type of organic acid disorder in which the body is unable to process proteins properly. Organic acid disorders lead to an abnormal buildup of particular acids known as organic acids. Abnormal levels of organic acids in the blood (organic acidemia), urine (organic aciduria), and tissues can be toxic and can cause serious health problems.  Normally, the body breaks down proteins from food into smaller parts called amino acids. Amino acids can be further processed to provide energy for growth and development. People with 2-methylbutyryl-CoA dehydrogenase deficiency have inadequate levels of an enzyme that helps process a particular amino acid called isoleucine.  Health problems related to 2-methylbutyryl-CoA dehydrogenase deficiency vary widely from severe and life-threatening to mild or absent. Signs and symptoms of this disorder can begin a few days after birth or later in childhood. The initial symptoms often include poor feeding, lack of energy (lethargy), vomiting, and an irritable mood. These symptoms sometimes progress to serious medical problems such as difficulty breathing, seizures, and coma. Additional problems can include poor growth, vision problems, learning disabilities, muscle weakness, and delays in motor skills such as standing and walking.  Symptoms of 2-methylbutyryl-CoA dehydrogenase deficiency may be triggered by prolonged periods without food (fasting), infections, or eating an increased amount of protein-rich foods. Some people with this disorder never have any signs or symptoms (asymptomatic). For example, individuals of Hmong ancestry identified with 2-methylbutyryl-CoA dehydrogenase deficiency through newborn screening are usually asymptomatic.

Topic: 2-methylbutyryl-CoA dehydrogenase deficiency
Question: What are the genetic changes related to 2-methylbutyryl-CoA dehydrogenase deficiency ?
Answer: Mutations in the ACADSB gene cause 2-methylbutyryl-CoA dehydrogenase deficiency.  The ACADSB gene provides instructions for making an enzyme called 2-methylbutyryl-CoA dehydrogenase that helps process the amino acid isoleucine. Mutations in the ACADSB gene reduce or eliminate the activity of this enzyme. With a shortage (deficiency) of 2-methylbutyryl-CoA dehydrogenase, the body is unable to break down isoleucine properly. As a result, isoleucine is not converted to energy, which can lead to characteristic features of this disorder, such as lethargy and muscle weakness. Also, an organic acid called 2-methylbutyrylglycine and related compounds may build up to harmful levels, causing serious health problems.

Topic: Turner syndrome
Question: What is (are) Turner syndrome ?
Answer: Turner syndrome is a chromosomal condition that affects development in females. The most common feature of Turner syndrome is short stature, which becomes evident by about age 5. An early loss of ovarian function (ovarian hypofunction or premature ovarian failure) is also very common. The ovaries develop normally at first, but egg cells (oocytes) usually die prematurely and most ovarian tissue degenerates before birth. Many affected girls do not undergo puberty unless they receive hormone therapy, and most are unable to conceive (infertile). A small percentage of females with Turner syndrome retain normal ovarian function through young adulthood.  About 30 percent of females with Turner syndrome have extra folds of skin on the neck (webbed neck), a low hairline at the back of the neck, puffiness or swelling (lymphedema) of the hands and feet, skeletal abnormalities, or kidney problems. One third to one half of individuals with Turner syndrome are born with a heart defect, such as a narrowing of the large artery leaving the heart (coarctation of the aorta) or abnormalities of the valve that connects the aorta with the heart (the aortic valve). Complications associated with these heart defects can be life-threatening.  Most girls and women with Turner syndrome have normal intelligence. Developmental delays, nonverbal learning disabilities, and behavioral problems are possible, although these characteristics vary among affected individuals.

Topic: Turner syndrome
Question: What are the genetic changes related to Turner syndrome ?
Answer: Turner syndrome is related to the X chromosome, which is one of the two sex chromosomes. People typically have two sex chromosomes in each cell: females have two X chromosomes, while males have one X chromosome and one Y chromosome. Turner syndrome results when one normal X chromosome is present in a female's cells and the other sex chromosome is missing or structurally altered. The missing genetic material affects development before and after birth.  About half of individuals with Turner syndrome have monosomy X, which means each cell in the individual's body has only one copy of the X chromosome instead of the usual two sex chromosomes. Turner syndrome can also occur if one of the sex chromosomes is partially missing or rearranged rather than completely absent. Some women with Turner syndrome have a chromosomal change in only some of their cells, which is known as mosaicism. Women with Turner syndrome caused by X chromosome mosaicism are said to have mosaic Turner syndrome.  Researchers have not determined which genes on the X chromosome are associated with most of the features of Turner syndrome. They have, however, identified one gene called SHOX that is important for bone development and growth. The loss of one copy of this gene likely causes short stature and skeletal abnormalities in women with Turner syndrome.

Topic: Turner syndrome
Question: Is Turner syndrome inherited ?
Answer: Most cases of Turner syndrome are not inherited. When this condition results from monosomy X, the chromosomal abnormality occurs as a random event during the formation of reproductive cells (eggs and sperm) in the affected person's parent. An error in cell division called nondisjunction can result in reproductive cells with an abnormal number of chromosomes. For example, an egg or sperm cell may lose a sex chromosome as a result of nondisjunction. If one of these atypical reproductive cells contributes to the genetic makeup of a child, the child will have a single X chromosome in each cell and will be missing the other sex chromosome.  Mosaic Turner syndrome is also not inherited. In an affected individual, it occurs as a random event during cell division in early fetal development. As a result, some of an affected person's cells have the usual two sex chromosomes, and other cells have only one copy of the X chromosome. Other sex chromosome abnormalities are also possible in females with X chromosome mosaicism.  Rarely, Turner syndrome caused by a partial deletion of the X chromosome can be passed from one generation to the next.

Topic: Kufs disease
Question: What is (are) Kufs disease ?
Answer: Kufs disease is a condition that primarily affects the nervous system, causing problems with movement and intellectual function that worsen over time. The signs and symptoms of Kufs disease typically appear around age 30, but they can develop anytime between adolescence and late adulthood.  Two types of Kufs disease have been described: type A and type B. The two types are differentiated by their genetic cause, pattern of inheritance, and certain signs and symptoms. Type A is characterized by a combination of seizures and uncontrollable muscle jerks (myoclonic epilepsy), a decline in intellectual function (dementia), impaired muscle coordination (ataxia), involuntary movements such as tremors or tics, and speech difficulties (dysarthria). Kufs disease type B shares many features with type A, but it is distinguished by changes in personality and is not associated with myoclonic epilepsy or dysarthria.  The signs and symptoms of Kufs disease worsen over time, and affected individuals usually survive about 15 years after the disorder begins.  Kufs disease is one of a group of disorders known as neuronal ceroid lipofuscinoses (NCLs), which are also known as Batten disease. These disorders affect the nervous system and typically cause progressive problems with vision, movement, and thinking ability. Kufs disease, however, does not affect vision. The different types of NCLs are distinguished by the age at which signs and symptoms first appear.

Answer: Collectively, all forms of NCL affect an estimated 1 in 100,000 individuals worldwide. NCLs are more common in Finland, where approximately 1 in 12,500 individuals have the condition. Kufs disease is thought to represent 1.3 to 10 percent of all NCLs.

Topic: Kufs disease
Question: What are the genetic changes related to Kufs disease ?
Answer: Mutations in the CLN6 or PPT1 gene cause Kufs disease type A, and mutations in the DNAJC5 or CTSF gene cause Kufs disease type B. Most of the proteins or enzymes produced from these genes are involved in breaking down proteins or clearing unneeded materials from cells.  The CLN6 gene provides instructions for making a protein that likely regulates the transport of certain proteins and fats within the cell. Based on this function, the CLN6 protein appears to help in the process of ridding cells of materials they no longer need.  The PPT1 gene provides instructions for making an enzyme called palmitoyl-protein thioesterase 1. This enzyme is found in structures called lysosomes, which are compartments within cells that break down and recycle different types of molecules. Palmitoyl-protein thioesterase 1 removes certain fats from proteins, which probably helps break down the proteins.  The protein produced from the DNAJC5 gene is called cysteine string protein alpha (CSP). This protein is found in the brain and plays a role in the transmission of nerve impulses by ensuring that nerve cells receive signals.  The enzyme produced from the CTSF gene is called cathepsin F. Cathepsin F acts as a protease, which modifies proteins by cutting them apart. Cathepsin F is found in many types of cells and is active in lysosomes. By cutting proteins apart, cathepsin F can break proteins down, turn on (activate) proteins, and regulate self-destruction of the cell (apoptosis).  Mutations in the CLN6, PPT1, DNAJC5, or CTSF gene usually reduce the activity of the gene or impair the function of the protein or enzyme produced from the gene. In many cases, these mutations cause incomplete breakdown of certain proteins and other materials. These materials accumulate in the lysosome, forming fatty substances called lipopigments. In other cases, it is unclear what causes the buildup of lipopigments. In Kufs disease, these accumulations occur in nerve cells (neurons) in the brain, resulting in cell dysfunction and eventually cell death. The progressive death of neurons leads to the signs and symptoms of Kufs disease.  Some people with either type of Kufs disease do not have an identified mutation in any of these four genes. In these individuals, the cause of the condition is unknown.

Topic: Kufs disease
Question: Is Kufs disease inherited ?
Answer: Kufs disease type A, caused by mutations in the CLN6 or PPT1 gene, has 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.  Kufs disease type B, caused by mutations in the DNAJC5 or CTSF gene, has an autosomal dominant pattern of inheritance. Autosomal dominant inheritance means one copy of the altered gene in each cell is sufficient to cause the disorder. Most cases of Kufs disease type B occur in people with no history of the disorder in their family.

Topic: Mayer-Rokitansky-Kster-Hauser syndrome
Question: What is (are) Mayer-Rokitansky-Kster-Hauser syndrome ?
Answer: Mayer-Rokitansky-Kster-Hauser (MRKH) syndrome is a disorder that occurs in females and mainly affects the reproductive system. This condition causes the vagina and uterus to be underdeveloped or absent. Affected women usually do not have menstrual periods due to the absent uterus. Often, the first noticeable sign of MRKH syndrome is that menstruation does not begin by age 16 (primary amenorrhea). Women with MRKH syndrome have a female chromosome pattern (46,XX) and normally functioning ovaries. They also have normal female external genitalia and normal breast and pubic hair development. Although women with this condition are usually unable to carry a pregnancy, they may be able to have children through assisted reproduction.  Women with MRKH syndrome may also have abnormalities in other parts of the body. The kidneys may be abnormally formed or positioned, or one kidney may fail to develop (unilateral renal agenesis). Affected individuals commonly develop skeletal abnormalities, particularly of the spinal bones (vertebrae). Females with MRKH syndrome may also have hearing loss or heart defects.

Topic: Mayer-Rokitansky-Kster-Hauser syndrome
Question: What are the genetic changes related to Mayer-Rokitansky-Kster-Hauser syndrome ?
Answer: The cause of MRKH syndrome is unknown, although it probably results from a combination of genetic and environmental factors. Researchers have not identified any genes associated with MRKH syndrome.  The reproductive abnormalities of MRKH syndrome are due to incomplete development of the Mllerian duct. This structure in the embryo develops into the uterus, fallopian tubes, cervix, and the upper part of the vagina. The cause of the abnormal development of the Mllerian duct in affected individuals is unknown. Originally, researchers believed that MRKH syndrome was caused by something the fetus was exposed to during pregnancy, such as a medication or maternal illness. However, studies have not identified an association with maternal drug use, illness, or other factors. It is also unclear why some affected individuals have abnormalities in parts of the body other than the reproductive system.

Question: Is Mayer-Rokitansky-Kster-Hauser syndrome inherited ?
Answer: Most cases of MRKH syndrome occur in people with no history of the disorder in their family.  Less often, MRKH syndrome is passed through generations in families. Its inheritance pattern is usually unclear because the signs and symptoms of the condition frequently vary among affected individuals in the same family. However, in some families, the condition appears to have an autosomal dominant pattern of inheritance. Autosomal dominant inheritance means that one copy of the altered gene in each cell is typically sufficient to cause the disorder, although no genes have been associated with MRKH syndrome.
