What are the genetic changes related to rippling muscle disease ? 

Rippling muscle disease can be caused by mutations in the CAV3 gene. Muscle conditions caused by CAV3 gene mutations are called caveolinopathies. The CAV3 gene provides instructions for making a protein called caveolin-3, which is found in the membrane surrounding muscle cells. This protein is the main component of caveolae, which are small pouches in the muscle cell membrane. Within the caveolae, the caveolin-3 protein acts as a scaffold to organize other molecules that are important for cell signaling and maintenance of the cell structure. It may also help regulate calcium levels in muscle cells, which play a role in controlling muscle contraction and relaxation.  CAV3 gene mutations that cause rippling muscle disease result in a shortage of caveolin-3 protein in the muscle cell membrane. Researchers suggest that the reduction in caveolin-3 protein disrupts the normal control of calcium levels in muscle cells, leading to abnormal muscle contractions in response to stimulation.  In addition to rippling muscle disease, CAV3 gene mutations can cause other caveolinopathies including CAV3-related distal myopathy, limb-girdle muscular dystrophy, isolated hyperCKemia, and a heart disorder called hypertrophic cardiomyopathy. Several CAV3 gene mutations have been found to cause different caveolinopathies in different individuals. It is unclear why a single CAV3 gene mutation may cause different patterns of signs and symptoms, even within the same family.  Some people with rippling muscle disease do not have mutations in the CAV3 gene. The cause of the disorder in these individuals is unknown.
Is rippling muscle disease inherited ? 

Rippling muscle disease is usually inherited in an autosomal dominant pattern, but it is occasionally inherited in an autosomal recessive pattern.  Autosomal dominant inheritance means that one copy of an altered CAV3 gene in each cell is sufficient to cause the disorder. In most cases, an affected person has one parent with rippling muscle disease or another caveolinopathy. Rare cases result from new mutations in the gene and occur in people with no history of caveolinopathies in their family.  Autosomal recessive inheritance means that both copies of the CAV3 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. People with autosomal recessive rippling muscle disease generally have more severe signs and symptoms than do people with the autosomal dominant form.

What is (are) juvenile myoclonic epilepsy ? 

Juvenile myoclonic epilepsy is a condition characterized by recurrent seizures (epilepsy). This condition begins in childhood or adolescence, usually between ages 12 and 18, and lasts into adulthood. The most common type of seizure in people with this condition is myoclonic seizures, which cause rapid, uncontrolled muscle jerks. People with this condition may also have generalized tonic-clonic seizures (also known as grand mal seizures), which cause muscle rigidity, convulsions, and loss of consciousness. Sometimes, affected individuals have absence seizures, which cause loss of consciousness for a short period that appears as a staring spell. Typically, people with juvenile myoclonic epilepsy develop the characteristic myoclonic seizures in adolescence, then develop generalized tonic-clonic seizures a few years later. Although seizures can happen at any time, they occur most commonly in the morning, shortly after awakening. Seizures can be triggered by a lack of sleep, extreme tiredness, stress, or alcohol consumption.
How many people are affected by juvenile myoclonic epilepsy ? 

Juvenile myoclonic epilepsy affects an estimated 1 in 1,000 people worldwide. Approximately 5 percent of people with epilepsy have juvenile myoclonic epilepsy.
What are the genetic changes related to juvenile myoclonic epilepsy ? 

The genetics of juvenile myoclonic epilepsy are complex and not completely understood. Mutations in one of several genes can cause or increase susceptibility to this condition. The most studied of these genes are the GABRA1 gene and the EFHC1 gene, although mutations in at least three other genes have been identified in people with this condition. Many people with juvenile myoclonic epilepsy do not have mutations in any of these genes. Changes in other, unidentified genes are likely involved in this condition.  A mutation in the GABRA1 gene has been identified in several members of a large family with juvenile myoclonic epilepsy. The GABRA1 gene provides instructions for making one piece, the alpha-1 (1) subunit, of the GABAA receptor protein. The GABAA receptor acts as a channel that allows negatively charged chlorine atoms (chloride ions) to cross the cell membrane. After infancy, the influx of chloride ions creates an environment in the cell that inhibits signaling between nerve cells (neurons) and prevents the brain from being overloaded with too many signals. Mutations in the GABRA1 gene lead to an altered 1 subunit and a decrease in the number of GABAA receptors available. As a result, the signaling between neurons is not controlled, which can lead to overstimulation of neurons. Researchers believe that the overstimulation of certain neurons in the brain triggers the abnormal brain activity associated with seizures.  Mutations in the EFHC1 gene have been associated with juvenile myoclonic epilepsy in a small number of people. The EFHC1 gene provides instructions for making a protein that also plays a role in neuron activity, although its function is not completely understood. The EFHC1 protein is attached to another protein that acts as a calcium channel. This protein allows positively charged calcium ions to cross the cell membrane. The movement of these ions is critical for normal signaling between neurons. The EFHC1 protein is thought to help regulate the balance of calcium ions inside the cell, although the mechanism is unclear. In addition, studies show that the EFHC1 protein may be involved in the self-destruction of cells. EFHC1 gene mutations reduce the function of the EFHC1 protein. Researchers suggest that this reduction causes an increase in the number of neurons and disrupts the calcium balance. Together, these effects may lead to overstimulation of neurons and trigger seizures.
Is juvenile myoclonic epilepsy inherited ? 

The inheritance pattern of juvenile myoclonic epilepsy is not completely understood. When the condition is caused by mutations in the GABRA1 gene, it is inherited in an autosomal dominant pattern, which means one copy of the altered gene in each cell is sufficient to cause the disorder. The inheritance pattern of juvenile myoclonic epilepsy caused by mutations in the EFHC1 gene is not known.  Although juvenile myoclonic epilepsy can run in families, many cases occur in people with no family history of the disorder.

What is (are) prostate cancer ? 

Prostate cancer is a common disease that affects men, usually in middle age or later. In this disorder, certain cells in the prostate become abnormal and multiply without control or order to form a tumor. The prostate is a gland that surrounds the male urethra and helps produce semen, the fluid that carries sperm.  Early prostate cancer usually does not cause pain, and most affected men exhibit no noticeable symptoms. Men are often diagnosed as the result of health screenings, such as a blood test for a substance called prostate specific antigen (PSA) or a medical procedure called a digital rectal exam. As the tumor grows larger, signs and symptoms can include difficulty starting or stopping the flow of urine, a feeling of not being able to empty the bladder completely, blood in the urine or semen, or pain with ejaculation. However, these changes can also occur with many other genitourinary conditions. Having one or more of these symptoms does not necessarily mean that a man has prostate cancer.  The severity and outcome of prostate cancer varies widely. Early-stage prostate cancer can usually be treated successfully, and some older men have prostate tumors that grow so slowly that they may never cause health problems during their lifetime, even without treatment. In other men, however, the cancer is much more aggressive; in these cases, prostate cancer can be life-threatening.  Some cancerous tumors can invade surrounding tissue and spread to other parts of the body. Tumors that begin at one site and then spread to other areas of the body are called metastatic cancers. The signs and symptoms of metastatic cancer depend on where the disease has spread. If prostate cancer spreads, cancerous cells most often appear in the lymph nodes, bones, lungs, liver, or brain. Bone metastases of prostate cancer most often cause pain in the lower back, pelvis, or hips.  A small percentage of all prostate cancers cluster in families. These hereditary cancers are associated with inherited gene mutations. Hereditary prostate cancers tend to develop earlier in life than non-inherited (sporadic) cases.
How many people are affected by prostate cancer ? 

About 1 in 7 men will be diagnosed with prostate cancer at some time during their life. In addition, studies indicate that many older men have undiagnosed prostate cancer that is non-aggressive and unlikely to cause symptoms or affect their lifespan. While most men who are diagnosed with prostate cancer do not die from it, this common cancer is still the second leading cause of cancer death among men in the United States.  More than 60 percent of prostate cancers are diagnosed after age 65, and the disorder is rare before age 40. In the United States, African Americans have a higher risk of developing prostate cancer than do men of other ethnic backgrounds, and they also have a higher risk of dying from the disease.
Is prostate cancer inherited ? 

Many cases of prostate cancer are not related to inherited gene changes. These cancers are associated with somatic mutations that occur only in certain cells in the prostate.  When prostate cancer is related to inherited gene changes, the way that cancer risk is inherited depends on the gene involved. For example, mutations in the BRCA1, BRCA2, and HOXB13 genes are inherited in an autosomal dominant pattern, which means one copy of the altered gene in each cell is sufficient to increase a person's chance of developing cancer. In other cases, the inheritance of prostate cancer risk is unclear. It is important to note that people inherit an increased risk of cancer, not the disease itself. Not all people who inherit mutations in these genes will develop cancer.

What is (are) maternally inherited diabetes and deafness ? 

Maternally inherited diabetes and deafness (MIDD) is a form of diabetes that is often accompanied by hearing loss, especially of high tones. The diabetes in MIDD is characterized by high blood sugar levels (hyperglycemia) resulting from a shortage of the hormone insulin, which regulates the amount of sugar in the blood. In MIDD, the diabetes and hearing loss usually develop in mid-adulthood, although the age that they occur varies from childhood to late adulthood. Typically, hearing loss occurs before diabetes.  Some people with MIDD develop an eye disorder called macular retinal dystrophy, which is characterized by colored patches in the light-sensitive tissue that lines the back of the eye (the retina). This disorder does not usually cause vision problems in people with MIDD. Individuals with MIDD also may experience muscle cramps or weakness, particularly during exercise; heart problems; kidney disease; and constipation. Individuals with MIDD are often shorter than their peers.
How many people are affected by maternally inherited diabetes and deafness ? 

About 1 percent of people with diabetes have MIDD. The condition is most common in the Japanese population and has been found in populations worldwide.
What are the genetic changes related to maternally inherited diabetes and deafness ? 

Mutations in the MT-TL1, MT-TK, or MT-TE gene cause MIDD. These genes are found in mitochondrial DNA, which is part of cellular structures called mitochondria. Although most DNA is packaged in chromosomes within the cell nucleus, mitochondria also have a small amount of their own DNA (known as mitochondrial DNA or mtDNA).  The MT-TL1, MT-TK, and MT-TE genes provide instructions for making molecules called transfer RNAs (tRNAs), which are chemical cousins of DNA. These molecules help assemble protein building blocks (amino acids) into functioning proteins. The MT-TL1 gene provides instructions for making a specific form of tRNA that is designated as tRNALeu(UUR). During protein assembly, this molecule attaches to the amino acid leucine (Leu) and inserts it into the appropriate locations in the growing protein. Similarly, the protein produced from the MT-TK gene, called tRNALys, attaches to the amino acid lysine (Lys) and inserts it into proteins being assembled. Also, the protein produced from the MT-TE gene, called tRNAGlu, attaches to the amino acid glutamic acid (Glu) and adds it to growing proteins.  These tRNA molecules are present only in mitochondria, and they help assemble proteins that are involved in producing energy for cells. In certain cells in the pancreas called beta cells, mitochondria also play a role in controlling the amount of sugar (glucose) in the bloodstream. In response to high glucose levels, mitochondria help trigger the release of insulin, which stimulates cells to take up glucose from the blood.  Mutations in the MT-TL1, MT-TK, or MT-TE gene reduce the ability of tRNA to add amino acids to growing proteins, which slows protein production in mitochondria and impairs their functioning. Researchers believe that the disruption of mitochondrial function lessens the ability of mitochondria to help trigger insulin release. In people with this condition, diabetes results when the beta cells do not produce enough insulin to regulate blood sugar effectively. Researchers have not determined how the mutations lead to hearing loss or the other features of MIDD.
Is maternally inherited diabetes and deafness inherited ? 

MIDD is inherited in a mitochondrial pattern, which is also known as maternal inheritance. This pattern of inheritance applies to genes contained in mtDNA. Because egg cells, but not sperm cells, contribute mitochondria to the developing embryo, children can only inherit disorders resulting from mtDNA mutations from their mother. These disorders can appear in every generation of a family and can affect both males and females, but fathers do not pass traits associated with changes in mtDNA to their children.  Most of the body's cells contain thousands of mitochondria, each with one or more copies of mtDNA. These cells can have a mix of mitochondria containing mutated and unmutated DNA (heteroplasmy). The severity of MIDD is thought to be associated with the percentage of mitochondria with the mtDNA mutation.

How many people are affected by Klippel-Feil syndrome ? 

Klippel-Feil syndrome is estimated to occur in 1 in 40,000 to 42,000 newborns worldwide. Females seem to be affected slightly more often than males.
What are the genetic changes related to Klippel-Feil syndrome ? 

Mutations in the GDF6, GDF3, or MEOX1 gene can cause Klippel-Feil syndrome. These genes are involved in proper bone development. The protein produced from the GDF6 gene is necessary for the formation of bones and joints, including those in the spine. While the protein produced from the GDF3 gene is known to be involved in bone development, its exact role is unclear. The protein produced from the MEOX1 gene, called homeobox protein MOX-1, regulates the process that begins separating vertebrae from one another during early development.  GDF6 and GDF3 gene mutations that cause Klippel-Feil syndrome likely lead to reduced function of the respective proteins. MEOX1 gene mutations lead to a complete lack of homeobox protein MOX-1. Although the GDF6, GDF3, and homeobox protein MOX-1 proteins are involved in bone development, particularly formation of vertebrae, it is unclear how a shortage of one of these proteins leads to incomplete separation of the cervical vertebrae in people with Klippel-Feil syndrome.  When Klippel-Feil syndrome is a feature of another disorder, it is caused by mutations in genes involved in the other disorder.
Is Klippel-Feil syndrome inherited ? 

When Klippel-Feil syndrome is caused by mutations in the GDF6 or GDF3 genes, it is inherited in an autosomal dominant pattern, which means one copy of the altered gene in each cell is sufficient to cause the disorder.  When caused by mutations in the MEOX1 gene, Klippel-Feil syndrome 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.  As a feature of another disorder, Klippel-Feil syndrome is inherited in whatever pattern the other disorder follows.

How many people are affected by abdominal wall defect ? 

Abdominal wall defects are uncommon. Omphalocele affects an estimated 2 to 2.5 in 10,000 newborns. Approximately 2 to 6 in 10,000 newborns are affected by gastroschisis, although researchers have observed that this malformation is becoming more common. Abdominal wall defects are more common among pregnancies that do not survive to term (miscarriages and stillbirths).
What are the genetic changes related to abdominal wall defect ? 

No genetic mutations are known to cause an abdominal wall defect. Multiple genetic and environmental factors likely influence the development of this disorder. Omphalocele and gastroschisis are caused by different errors in fetal development.  Omphalocele occurs during an error in digestive tract development. During the formation of the abdominal cavity in the sixth to tenth weeks of fetal development, the intestines normally protrude into the umbilical cord but recede back into the abdomen as development continues. Omphalocele occurs when the intestines do not recede back into the abdomen, but remain in the umbilical cord. Other abdominal organs can also protrude through this opening, resulting in the varied organ involvement that occurs in omphalocele.  The error that leads to gastroschisis formation is unknown. It is thought to be either a disruption in the blood flow to the digestive tract or a lack of development or injury to gastrointestinal tissue early in fetal development. For reasons that are unknown, women under the age of 20 are at the greatest risk of having a baby with gastroschisis. Other risk factors in pregnancy may include taking medications that constrict the blood vessels (called vasoconstrictive drugs) or smoking, although these risk factors have not been confirmed.
Is abdominal wall defect inherited ? 

Most cases of abdominal wall defect are sporadic, which means they occur in people with no history of the disorder in their family. Multiple genetic and environmental factors likely play a part in determining the risk of developing this disorder.  When an abdominal wall defect, most often omphalocele, is a feature of a genetic condition, it is inherited in the pattern of that condition.
