 How many people are affected by retroperitoneal fibrosis ? 
 Retroperitoneal fibrosis occurs in 1 in 200,000 to 500,000 people per year. The disorder occurs approximately twice as often in men as it does in women, but the reason for this difference is unclear.
This is a medical question of type : genetic changes 
 What are the genetic changes related to retroperitoneal fibrosis ? 
 No genes associated with retroperitoneal fibrosis have been identified.  Retroperitoneal fibrosis occasionally occurs with autoimmune disorders, which result when the immune system malfunctions and attacks the body's own organs and tissues. Researchers suggest that the immune system may be involved in the development of retroperitoneal fibrosis. They propose that the immune system may be reacting abnormally to blood vessels damaged by fatty buildup (atherosclerosis) or to certain drugs, infections, or trauma. In many cases, the reason for the abnormal immune system reaction is unknown. Such cases are described as idiopathic.
This is a medical question of type : inheritance 
 Is retroperitoneal fibrosis inherited ? 
 Most cases of retroperitoneal fibrosis are sporadic, which means that they occur in people with no apparent history of the disorder in their family. In rare cases, the condition has been reported to occur in a few members of the same family, but the inheritance pattern is unknown.

 What is (are) Legg-Calv-Perthes disease ? 
 Legg-Calv-Perthes disease is a bone disorder that affects the hips. Usually, only one hip is involved, but in about 10 percent of cases, both hips are affected. Legg-Calv-Perthes disease begins in childhood, typically between ages 4 and 8, and affects boys more frequently than girls.  In this condition, the upper end of the thigh bone, known as the femoral head, breaks down. As a result, the femoral head is no longer round and does not move easily in the hip socket, which leads to hip pain, limping, and restricted leg movement. The bone eventually begins to heal itself through a normal process called bone remodeling, by which old bone is removed and new bone is created to replace it. This cycle of breakdown and healing can recur multiple times. Affected individuals are often shorter than their peers due to the bone abnormalities. Many people with Legg-Calv-Perthes disease go on to develop a painful joint disorder called osteoarthritis in the hips at an early age.

 How many people are affected by Legg-Calv-Perthes disease ? 
 The incidence of Legg-Calv-Perthes disease varies by population. The condition is most common in white populations, in which it affects an estimated 1 to 3 in 20,000 children under age 15.
This is a medical question of type : genetic changes 
 What are the genetic changes related to Legg-Calv-Perthes disease ? 
 Legg-Calv-Perthes disease is usually not caused by genetic factors. The cause in these cases is unknown. In a small percentage of cases, mutations in the COL2A1 gene cause the bone abnormalities characteristic of Legg-Calv-Perthes disease. The COL2A1 gene provides instructions for making a protein that forms type II collagen. This type of collagen is found mostly in cartilage, a tough but 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. Type II collagen is essential for the normal development of bones and other connective tissues that form the body's supportive framework.  COL2A1 gene mutations involved in Legg-Calv-Perthes disease lead to production of an altered protein; collagen that contains this protein may be less stable than normal. Researchers speculate that the breakdown of bone characteristic of Legg-Calv-Perthes disease is caused by impaired blood flow to the femoral head, which leads to death of the bone tissue (osteonecrosis); however it is unclear how abnormal type II collagen is involved in this process or why the hips are specifically affected.
This is a medical question of type : inheritance 
 Is Legg-Calv-Perthes disease inherited ? 
 When associated with COL2A1 gene mutations, the condition is inherited in an autosomal dominant pattern, which means one copy of the altered COL2A1 gene in each cell is sufficient to cause the disorder.  Most COL2A1-associated cases result from new mutations in the gene and occur in people with no history of the disorder in their family. These cases are referred to as sporadic. In other cases, the condition is passed through families. In these cases, referred to as familial, an affected person inherits the mutation from one affected parent.

 What is (are) Beckwith-Wiedemann syndrome ? 
 Beckwith-Wiedemann syndrome is a condition that affects many parts of the body. It is classified as an overgrowth syndrome, which means that affected infants are considerably larger than normal (macrosomia) and tend to be taller than their peers during childhood. Growth begins to slow by about age 8, and adults with this condition are not unusually tall. In some children with Beckwith-Wiedemann syndrome, specific parts of the body on one side or the other may grow abnormally large, leading to an asymmetric or uneven appearance. This unusual growth pattern, which is known as hemihyperplasia, usually becomes less apparent over time.  The signs and symptoms of Beckwith-Wiedemann syndrome vary among affected individuals. Some children with this condition are born with an opening in the wall of the abdomen (an omphalocele) that allows the abdominal organs to protrude through the belly-button. Other abdominal wall defects, such as a soft out-pouching around the belly-button (an umbilical hernia), are also common. Some infants with Beckwith-Wiedemann syndrome have an abnormally large tongue (macroglossia), which may interfere with breathing, swallowing, and speaking. Other major features of this condition include abnormally large abdominal organs (visceromegaly), creases or pits in the skin near the ears, low blood sugar (hypoglycemia) in infancy, and kidney abnormalities.  Children with Beckwith-Wiedemann syndrome are at an increased risk of developing several types of cancerous and noncancerous tumors, particularly a form of kidney cancer called Wilms tumor and a form of liver cancer called hepatoblastoma. Tumors develop in about 10 percent of people with this condition and almost always appear in childhood.  Most children and adults with Beckwith-Wiedemann syndrome do not have serious medical problems associated with the condition. Their life expectancy is usually normal.

 How many people are affected by Beckwith-Wiedemann syndrome ? 
 Beckwith-Wiedemann syndrome affects an estimated 1 in 13,700 newborns worldwide. The condition may actually be more common than this estimate because some people with mild symptoms are never diagnosed.
This is a medical question of type : genetic changes 
 What are the genetic changes related to Beckwith-Wiedemann syndrome ? 
 The genetic causes of Beckwith-Wiedemann syndrome are complex. The condition usually results from the abnormal regulation of genes in a particular region of chromosome 11. People normally inherit one copy of this chromosome from each parent. For most genes on chromosome 11, both copies of the gene are expressed, or "turned on," in cells. For some genes, however, only the copy inherited from a person's father (the paternally inherited copy) is expressed. For other genes, only the copy inherited from a person's mother (the maternally inherited copy) is expressed. These parent-specific differences in gene expression are caused by a phenomenon called genomic imprinting. Abnormalities involving genes on chromosome 11 that undergo genomic imprinting are responsible for most cases of Beckwith-Wiedemann syndrome.  At least half of all cases result from changes in a process called methylation. Methylation is a chemical reaction that attaches small molecules called methyl groups to certain segments of DNA. In genes that undergo genomic imprinting, methylation is one way that a gene's parent of origin is marked during the formation of egg and sperm cells. Beckwith-Wiedemann syndrome is often associated with changes in regions of DNA on chromosome 11 called imprinting centers (ICs). ICs control the methylation of several genes that are involved in normal growth, including the CDKN1C, H19, IGF2, and KCNQ1OT1 genes. Abnormal methylation disrupts the regulation of these genes, which leads to overgrowth and the other characteristic features of Beckwith-Wiedemann syndrome.  About twenty percent of cases of Beckwith-Wiedemann syndrome are caused by a genetic change known as paternal uniparental disomy (UPD). Paternal UPD causes people to have two active copies of paternally inherited genes rather than one active copy from the father and one inactive copy from the mother. People with paternal UPD are also missing genes that are active only on the maternally inherited copy of the chromosome. In Beckwith-Wiedemann syndrome, paternal UPD usually occurs early in embryonic development and affects only some of the body's cells. This phenomenon is called mosaicism. Mosaic paternal UPD leads to an imbalance in active paternal and maternal genes on chromosome 11, which underlies the signs and symptoms of the disorder.  Less commonly, mutations in the CDKN1C gene cause Beckwith-Wiedemann syndrome. This gene provides instructions for making a protein that helps control growth before birth. Mutations in the CDKN1C gene prevent this protein from restraining growth, which leads to the abnormalities characteristic of Beckwith-Wiedemann syndrome.  About 1 percent of all people with Beckwith-Wiedemann syndrome have a chromosomal abnormality such as a rearrangement (translocation), abnormal copying (duplication), or loss (deletion) of genetic material from chromosome 11. Like the other genetic changes responsible for Beckwith-Wiedemann syndrome, these abnormalities disrupt the normal regulation of certain genes on this chromosome.
This is a medical question of type : inheritance 
 Is Beckwith-Wiedemann syndrome inherited ? 
 In about 85 percent of cases of Beckwith-Wiedemann syndrome, only one person in a family has been diagnosed with the condition. However, parents of one child with Beckwith-Wiedemann syndrome may be at risk of having other children with the disorder. This risk depends on the genetic cause of the condition.  Another 10 to 15 percent of people with Beckwith-Wiedemann syndrome are part of families with more than one affected family member. In most of these families, the condition appears to have an autosomal dominant pattern of inheritance. Autosomal dominant inheritance means that one copy of an altered gene in each cell is typically sufficient to cause the disorder. In most of these cases, individuals with Beckwith-Wiedemann syndrome inherit the genetic change from their mothers. Occasionally, a person who inherits the altered gene will not have any of the characteristic signs and symptoms of the condition.  Rarely, Beckwith-Wiedemann syndrome results from changes in the structure of chromosome 11. Some of these chromosomal abnormalities are inherited from a parent, while others occur as random events during the formation of reproductive cells (eggs and sperm) or in the earliest stages of development before birth.

 What is (are) ataxia with oculomotor apraxia ? 
 Ataxia with oculomotor apraxia is a condition characterized by progressive problems with movement. The hallmark of this condition is difficulty coordinating movements (ataxia), which is often the first symptom. Most affected people also have oculomotor apraxia, which makes it difficult to move their eyes side-to-side. People with oculomotor apraxia have to turn their head to see things in their side (peripheral) vision.  There are multiple types of ataxia with oculomotor apraxia. The types are very similar but are caused by mutations in different genes. The two most common types (types 1 and 2) share features, in addition to ataxia and oculomotor apraxia, that include involuntary jerking movements (chorea), muscle twitches (myoclonus), and disturbances in nerve function (neuropathy). In type 1, ataxia beings around age 4; in type 2, ataxia begins around age 15. Chorea and myoclonus tend to disappear gradually in type 1; these movement problems persist throughout life in type 2. Individuals with type 1 often develop wasting (atrophy) in their hands and feet, which further impairs movement. Nearly all individuals with ataxia with oculomotor apraxia develop neuropathy, which leads to absent reflexes and weakness. Neuropathy causes many individuals with this condition to require wheelchair assistance, typically 10 to 15 years after the start of movement problems. Intelligence is usually not affected by this condition, but some people have intellectual disability.  People with ataxia with oculomotor apraxia type 1 tend to have decreased amounts of a protein called albumin, which transports molecules in the blood. This decrease in albumin likely causes an increase in the amount of cholesterol circulating in the bloodstream. Increased cholesterol levels may raise a person's risk of developing heart disease. People with ataxia with oculomotor apraxia type 2 have increased blood cholesterol, but they have normal albumin levels. Individuals with type 2 tend to have high amounts of a protein called alpha-fetoprotein (AFP) in their blood. (An increase in the level of this protein is normally seen in the bloodstream of pregnant women.) Affected individuals may also have high amounts of a protein called creatine phosphokinase (CPK) in their blood. This protein is found mainly in muscle tissue. The effect of abnormally high levels of AFP or CPK in people with ataxia with oculomotor apraxia type 2 is unknown.

 How many people are affected by ataxia with oculomotor apraxia ? 
 Ataxia with oculomotor apraxia is a rare condition. Type 1 is a common form of ataxia in Portugal and Japan. Type 2 is estimated to occur in 1 in 900,000 individuals worldwide.
This is a medical question of type : genetic changes 
 What are the genetic changes related to ataxia with oculomotor apraxia ? 
 Mutations in the APTX and SETX genes cause ataxia with oculomotor apraxia types 1 and 2, respectively. These genes provide instructions for making proteins that are involved in DNA repair.  Mutations in the APTX or SETX gene decrease the amount of functional protein that is available to repair damaged DNA, which leads to the accumulation of breaks in DNA. These breaks can be caused by natural and medical radiation or other environmental exposures, and also occur when chromosomes exchange genetic material in preparation for cell division. DNA damage that is not repaired causes the cell to be unstable and can lead to cell death. It is thought that nerve cells in the brain are particularly affected by cell death because these cells do not copy (replicate) themselves to replace cells that have been lost. The part of the brain involved in coordinating movements (the cerebellum) is especially affected. It is thought that the loss of brain cells in the cerebellum causes the movement problems characteristic of ataxia with oculomotor apraxia.  Mutations in other genes are responsible for the rare types of ataxia with oculomotor apraxia.
This is a medical question of type : inheritance 
 Is ataxia with oculomotor apraxia 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 signs and symptoms of the condition.

 What is (are) Costello syndrome ? 
 Costello syndrome is a disorder that affects many parts of the body. This condition is characterized by delayed development and intellectual disability, loose folds of skin (which are especially noticeable on the hands and feet), unusually flexible joints, and distinctive facial features including a large mouth. Heart problems are common, including an abnormal heartbeat (arrhythmia), structural heart defects, and a type of heart disease that enlarges and weakens the heart muscle (hypertrophic cardiomyopathy). Infants with Costello syndrome may be larger than average at birth, but most have difficulty feeding and grow more slowly than other children. People with this condition have relatively short stature and may have reduced growth hormone levels. Other signs and symptoms of Costello syndrome can include tight Achilles tendons (which connect the calf muscles to the heel), weak muscle tone (hypotonia), a structural abnormality of the brain called a Chiari I malformation, skeletal abnormalities, dental problems, and problems with vision.  Beginning in early childhood, people with Costello syndrome are at an increased risk of developing certain cancerous and noncancerous tumors. The most common noncancerous tumors associated with this condition are papillomas, which are small, wart-like growths that usually develop around the nose and mouth or near the anus. The most common cancerous tumor associated with Costello syndrome is a childhood cancer called rhabdomyosarcoma, which begins in muscle tissue. Neuroblastoma, a tumor that arises in developing nerve cells, also has been reported in children and adolescents with this syndrome. In addition, some teenagers with Costello syndrome have developed transitional cell carcinoma, a form of bladder cancer that is usually seen in older adults.  The signs and symptoms of Costello syndrome overlap significantly with those of two other genetic conditions, cardiofaciocutaneous syndrome (CFC syndrome) and Noonan syndrome. In affected infants, it can be difficult to tell the three conditions apart based on their physical features. However, the conditions can be distinguished by their genetic cause and by specific patterns of signs and symptoms that develop later in childhood.

 How many people are affected by Costello syndrome ? 
 This condition is very rare; it probably affects 200 to 300 people worldwide. Reported estimates of Costello syndrome prevalence range from 1 in 300,000 to 1 in 1.25 million people.
This is a medical question of type : genetic changes 
 What are the genetic changes related to Costello syndrome ? 
 Mutations in the HRAS gene cause Costello syndrome. This gene provides instructions for making a protein called H-Ras, which is part of a pathway that helps control cell growth and division. Mutations that cause Costello syndrome lead to the production of an H-Ras protein that is abnormally turned on (active). The overactive protein directs cells to grow and divide constantly, which can lead to the development of cancerous and noncancerous tumors. It is unclear how mutations in the HRAS gene cause the other features of Costello syndrome, but many of the signs and symptoms probably result from cell overgrowth and abnormal cell division.  Some people with signs and symptoms of Costello syndrome do not have an identified mutation in the HRAS gene. These individuals may actually have CFC syndrome or Noonan syndrome, which are caused by mutations in related genes. The proteins produced from these genes interact with one another and with the H-Ras protein as part of the same cell growth and division pathway. These interactions help explain why mutations in different genes can cause conditions with overlapping signs and symptoms.
This is a medical question of type : inheritance 
 Is Costello syndrome inherited ? 
 Costello syndrome is considered to be an autosomal dominant condition, which means one copy of the altered gene in each cell is sufficient to cause the disorder. Almost all reported cases have resulted from new gene mutations and have occurred in people with no history of the disorder in their family.
