What is (are) chordoma ? 
 A chordoma is a rare type of cancerous tumor that can occur anywhere along the spine, from the base of the skull to the tailbone. Chordomas grow slowly, gradually extending into the bone and soft tissue around them. They often recur after treatment, and in about 40 percent of cases the cancer spreads (metastasizes) to other areas of the body, such as the lungs.  Approximately half of all chordomas occur at the base of the spine (sacrum), about one third occur in the base of the skull (occiput), and the rest occur in the cervical (neck), thoracic (upper back), or lumbar (lower back) vertebrae of the spine. As the chordoma grows, it puts pressure on the adjacent areas of the brain or spinal cord, leading to the signs and symptoms of the disorder. A chordoma anywhere along the spine may cause pain, weakness, or numbness in the back, arms, or legs. A chordoma at the base of the skull (occipital chordoma) may lead to double vision (diplopia) and headaches. A chordoma that occurs in the tailbone (coccygeal chordoma) may result in a lump large enough to be felt through the skin and may cause problems with bladder or bowel function.  Chordomas typically occur in adults between ages 40 and 70. About 5 percent of chordomas are diagnosed in children. For reasons that are unclear, males are affected about twice as often as females.
How many people are affected by chordoma ? 
 Chordomas are rare, occurring in approximately 1 per million individuals each year. Chordomas comprise fewer than 1 percent of tumors affecting the brain and spinal cord.
What are the genetic changes related to chordoma ? 
 Changes in the T gene have been associated with chordoma. An inherited duplication of the T gene identified in a few families is associated with an increased risk of developing a chordoma. Duplications or increases in activity (expression) of the T gene have also been identified in people with chordoma who have no history of the disorder in their family. In these individuals, the changes occur only in the tumor cells and are not inherited.  The T gene provides instructions for making a protein called brachyury. Brachyury is a member of a protein family called T-box proteins, which play critical roles during embryonic development. T-box proteins regulate the activity of other genes by attaching (binding) to specific regions of DNA. On the basis of this action, T-box proteins are called transcription factors.  The brachyury protein is especially important for the early development of the spine. In human embryos, a structure called the notochord is the precursor of the spinal column. The notochord disappears before birth, but in a small percentage of individuals, some of its cells remain in the base of the skull or in the spine. In rare cases these cells begin to grow and divide uncontrollably, invading the nearby bone and soft tissue and resulting in the development of a chordoma.  Duplications and increases in expression of the T gene both result in the production of excess brachyury protein. The specific mechanism by which excess brachyury protein contributes to the development of chordomas is unclear. Some people with chordoma do not have changes in the T gene, and the cause of the disorder in these individuals is unknown.
Is chordoma inherited ? 
 When development of a chordoma is associated with a duplication of the T gene inherited from a parent, one copy of the altered gene in each cell is sufficient to increase the risk of the disorder, which is an inheritance pattern called autosomal dominant. People with this duplication inherit an increased risk of this condition, not the condition itself.  Other cases of chordoma are sporadic, which means they occur in people with no history of the condition in their family.

What is (are) juvenile Paget disease ? 
 Juvenile Paget disease is a disorder that affects bone growth. This disease causes bones to be abnormally large, misshapen, and easily broken (fractured).  The signs of juvenile Paget disease appear in infancy or early childhood. As bones grow, they become progressively weaker and more deformed. These abnormalities usually become more severe during the adolescent growth spurt, when bones grow very quickly.  Juvenile Paget disease affects the entire skeleton, resulting in widespread bone and joint pain. The bones of the skull tend to grow unusually large and thick, which can lead to hearing loss. The disease also affects bones of the spine (vertebrae). The deformed vertebrae can collapse, leading to abnormal curvature of the spine. Additionally, weight-bearing long bones in the legs tend to bow and fracture easily, which can interfere with standing and walking.
How many people are affected by juvenile Paget disease ? 
 Juvenile Paget disease is rare; about 50 affected individuals have been identified worldwide.
What are the genetic changes related to juvenile Paget disease ? 
 Juvenile Paget disease is caused by mutations in the TNFRSF11B gene. This gene provides instructions for making a protein that is involved in bone remodeling, a normal process in which old bone is broken down and new bone is created to replace it.  Bones are constantly being remodeled, and the process is carefully controlled to ensure that bones stay strong and healthy. Mutations in the TNFRSF11B gene lead to a much faster rate of bone remodeling starting early in life. Bone tissue is broken down more quickly than usual, and when new bone tissue grows it is larger, weaker, and less organized than normal bone. This abnormally fast bone remodeling underlies the problems with bone growth characteristic of juvenile Paget disease.
Is juvenile Paget disease 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) anencephaly ? 
 Anencephaly is a condition that prevents the normal development of the brain and the bones of the skull. This condition results when a structure called the neural tube fails to close during the first few weeks of embryonic development. The neural tube is a layer of cells that ultimately develops into the brain and spinal cord. Because anencephaly is caused by abnormalities of the neural tube, it is classified as a neural tube defect.  Because the neural tube fails to close properly, the developing brain and spinal cord are exposed to the amniotic fluid that surrounds the fetus in the womb. This exposure causes the nervous system tissue to break down (degenerate). As a result, people with anencephaly are missing large parts of the brain called the cerebrum and cerebellum. These brain regions are necessary for thinking, hearing, vision, emotion, and coordinating movement. The bones of the skull are also missing or incompletely formed.  Because these nervous system abnormalities are so severe, almost all babies with anencephaly die before birth or within a few hours or days after birth.
How many people are affected by anencephaly ? 
 Anencephaly is one of the most common types of neural tube defect, affecting about 1 in 1,000 pregnancies. However, most of these pregnancies end in miscarriage, so the prevalence of this condition in newborns is much lower. An estimated 1 in 10,000 infants in the United States is born with anencephaly.
What are the genetic changes related to anencephaly ? 
 Anencephaly is a complex condition that is likely caused by the interaction of multiple genetic and environmental factors. Some of these factors have been identified, but many remain unknown.  Changes in dozens of genes in individuals with anencephaly and in their mothers may influence the risk of developing this type of neural tube defect. The best-studied of these genes is MTHFR, which provides instructions for making a protein that is involved in processing the vitamin folate (also called vitamin B9). A shortage (deficiency) of this vitamin is an established risk factor for neural tube defects. Changes in other genes related to folate processing and genes involved in the development of the neural tube have also been studied as potential risk factors for anencephaly. However, none of these genes appears to play a major role in causing the condition.  Researchers have also examined environmental factors that could contribute to the risk of anencephaly. As mentioned above, folate deficiency appears to play a significant role. Studies have shown that women who take supplements containing folic acid (the synthetic form of folate) before they get pregnant and very early in their pregnancy are significantly less likely to have a baby with a neural tube defect, including anencephaly. Other possible maternal risk factors for anencephaly include diabetes mellitus, obesity, exposure to high heat (such as a fever or use of a hot tub or sauna) in early pregnancy, and the use of certain anti-seizure medications during pregnancy. However, it is unclear how these factors may influence the risk of anencephaly.
Is anencephaly inherited ? 
 Most cases of anencephaly are sporadic, which means they occur in people with no history of the disorder in their family. A small percentage of cases have been reported to run in families; however, the condition does not have a clear pattern of inheritance. For parents who have had a child with anencephaly, the risk of having another affected child is increased compared with the risk in the general population.

What is (are) Adams-Oliver syndrome ? 
 Adams-Oliver syndrome is a rare condition that is present at birth. The primary features are an abnormality in skin development (called aplasia cutis congenita) and malformations of the limbs. A variety of other features can occur in people with Adams-Oliver syndrome.  Most people with Adams-Oliver syndrome have aplasia cutis congenita, a condition characterized by localized areas of missing skin typically occurring on the top of the head (the skull vertex). In some cases, the bone under the skin is also underdeveloped. Individuals with this condition commonly have scarring and an absence of hair growth in the affected area.  Abnormalities of the hands and feet are also common in people with Adams-Oliver syndrome. These most often involve the fingers and toes and can include abnormal nails, fingers or toes that are fused together (syndactyly), and abnormally short or missing fingers or toes (brachydactyly or oligodactyly). In some cases, other bones in the hands, feet, or lower limbs are malformed or missing.  Some affected infants have a condition called cutis marmorata telangiectatica congenita. This disorder of the blood vessels causes a reddish or purplish net-like pattern on the skin. In addition, people with Adams-Oliver syndrome can develop high blood pressure in the blood vessels between the heart and the lungs (pulmonary hypertension), which can be life-threatening. Other blood vessel problems and heart defects can occur in affected individuals.  In some cases, people with Adams-Oliver syndrome have neurological problems, such as developmental delay, learning disabilities, or abnormalities in the structure of the brain.
How many people are affected by Adams-Oliver syndrome ? 
 Adams-Oliver syndrome is a rare disorder; its prevalence is unknown.
Is Adams-Oliver syndrome inherited ? 
 Adams-Oliver syndrome can have different inheritance patterns. When caused by mutations in the ARHGAP31, DLL4, NOTCH1, or RBPJ gene, the condition is inherited in an autosomal dominant pattern. Autosomal dominant inheritance means that one copy of the altered gene in each cell is sufficient to cause the disorder. The altered gene is typically inherited from an affected parent. Some cases associated with NOTCH1 gene mutations result from new (de novo) mutations in the gene that occur during the formation of reproductive cells (eggs or sperm) or in early embryonic development. These cases occur in people with no history of the disorder in their family.  When caused by mutations in the DOCK6 or EOGT gene, Adams-Oliver syndrome is inherited in an autosomal recessive pattern. In conditions with this pattern of inheritance, 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) Jackson-Weiss syndrome ? 
 Jackson-Weiss syndrome is a genetic disorder characterized by foot abnormalities and the premature fusion of certain skull bones (craniosynostosis). This early fusion prevents the skull from growing normally and affects the shape of the head and face.  Many of the characteristic facial features of Jackson-Weiss syndrome result from premature fusion of the skull bones. Abnormal growth of these bones leads to a misshapen skull, widely spaced eyes, and a bulging forehead.  Foot abnormalities are the most consistent features of Jackson-Weiss syndrome. The first (big) toes are short and wide, and they bend away from the other toes. Additionally, the bones of some toes may be fused together (syndactyly) or abnormally shaped. The hands are almost always normal.  People with Jackson-Weiss syndrome usually have normal intelligence and a normal life span.
How many people are affected by Jackson-Weiss syndrome ? 
 Jackson-Weiss syndrome is a rare genetic disorder; its incidence is unknown.
What are the genetic changes related to Jackson-Weiss syndrome ? 
 Mutations in the FGFR2 gene cause Jackson-Weiss syndrome. This gene provides instructions for making a protein called fibroblast growth factor receptor 2. Among its multiple functions, this protein signals immature cells to become bone cells during embryonic development. A mutation in a specific part of the FGFR2 gene overstimulates signaling by the FGFR2 protein, which promotes the premature fusion of skull bones and affects the development of bones in the feet.
Is Jackson-Weiss syndrome inherited ? 
 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.

What is (are) mucolipidosis II alpha/beta ? 
 Mucolipidosis II alpha/beta (also known as I-cell disease) is a progressively debilitating disorder that affects many parts of the body. Most affected individuals do not survive past early childhood.  At birth, children with mucolipidosis II alpha/beta are small and have weak muscle tone (hypotonia) and a weak cry. Affected individuals grow slowly after birth and usually stop growing during the second year of life. Development is delayed, particularly the development of speech and motor skills such as sitting and standing.  Children with mucolipidosis II alpha/beta typically have several bone abnormalities, many of which are present at birth. Affected individuals may have an abnormally rounded upper back (kyphosis), feet that are abnormally rotated (clubfeet), dislocated hips, unusually shaped long bones, and short hands and fingers. People with this condition also have joint deformities (contractures) that significantly affect mobility. Most children with mucolipidosis II alpha/beta do not develop the ability to walk independently. Affected individuals have dysostosis multiplex, which refers to multiple skeletal abnormalities seen on x-ray.  Other features of mucolipidosis II alpha/beta include a soft out-pouching around the belly-button (umbilical hernia) or lower abdomen (inguinal hernia), heart valve abnormalities, distinctive-looking facial features that are described as "coarse," and overgrowth of the gums (gingival hypertrophy). Vocal cords can stiffen, resulting in a hoarse voice. The airway is narrow, which can contribute to prolonged or recurrent respiratory infections. Affected individuals may also have recurrent ear infections, which can lead to hearing loss.
How many people are affected by mucolipidosis II alpha/beta ? 
 Mucolipidosis II alpha/beta is a rare disorder, although its exact prevalence is unknown. It is estimated to occur in about 1 in 100,000 to 400,000 individuals worldwide.
What are the genetic changes related to mucolipidosis II alpha/beta ? 
 Mutations in the GNPTAB gene cause mucolipidosis II alpha/beta. This gene provides instructions for making part of an enzyme called GlcNAc-1-phosphotransferase. This enzyme helps prepare certain newly made enzymes for transport to lysosomes. Lysosomes are compartments within the cell that use digestive enzymes to break down large molecules into smaller ones that can be reused by cells. GlcNAc-1-phosphotransferase is involved in the process of attaching a molecule called mannose-6-phosphate (M6P) to specific digestive enzymes. Just as luggage is tagged at the airport to direct it to the correct destination, enzymes are often "tagged" after they are made so they get to where they are needed in the cell. M6P acts as a tag that indicates a digestive enzyme should be transported to the lysosome.  Mutations in the GNPTAB gene that cause mucolipidosis II alpha/beta prevent the production of any functional GlcNAc-1-phosphotransferase. Without this enzyme, digestive enzymes cannot be tagged with M6P and transported to lysosomes. Instead, they end up outside the cell and have increased digestive activity. The lack of digestive enzymes within lysosomes causes large molecules to accumulate there. Conditions that cause molecules to build up inside lysosomes, including mucolipidosis II alpha/beta, are called lysosomal storage disorders. The signs and symptoms of mucolipidosis II alpha/beta are most likely caused by the lack of digestive enzymes within lysosomes and the effects these enzymes have outside the cell.  Mutations in the GNPTAB gene can also cause a similar but milder disorder called mucolipidosis III alpha/beta. Instead of preventing the production of any enzyme, these mutations reduce the activity of GlcNAc-1-phosphotransferase. Mucolipidosis III alpha/beta and mucolipidosis II alpha/beta represent two ends of a spectrum of disease severity.
Is mucolipidosis II alpha/beta 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) myoclonus-dystonia ? 
 Myoclonus-dystonia is a movement disorder that typically affects the upper half of the body. Individuals with this condition experience quick, involuntary muscle jerking or twitching (myoclonus) that usually affects their arms, neck, and trunk. Less frequently, the legs are involved as well. More than half of affected individuals also develop dystonia, which is a pattern of involuntary muscle contractions that causes twisting and pulling movements of specific body parts. The dystonia associated with myoclonus-dystonia may affect a single part of the body, causing isolated problems such as a writer's cramp in the hand, or it may involve multiple areas of the body. Rarely, people with this condition have dystonia as their only symptom.  The movement problems usually appear in childhood or early adolescence, and myoclonus is typically the initial symptom. Myoclonus may be triggered by movement or stimulation of the affected body area, stress, sudden noise, or caffeine. In some cases, the myoclonus gets worse over time; in other cases, people experience a spontaneous improvement (remission) of their symptoms. It is unclear why the movement abnormalities improve in some people but not in others.  People with myoclonus-dystonia may have an increased risk for developing psychological conditions such as depression, anxiety, panic attacks, and obsessive-compulsive disorder (OCD).
How many people are affected by myoclonus-dystonia ? 
 The prevalence of myoclonus-dystonia is unknown. This condition has been described in people worldwide.
What are the genetic changes related to myoclonus-dystonia ? 
 Mutations in the SGCE gene cause myoclonus-dystonia. The SGCE gene provides instructions for making a protein called epsilon ()-sarcoglycan, whose function is unknown. The -sarcoglycan protein is located within the cell membranes of many tissues, but it is most abundant in nerve cells (neurons) in the brain and in muscle cells.  SGCE gene mutations that cause myoclonus-dystonia result in a shortage of -sarcoglycan protein. The protein shortage seems to affect the regions of the brain involved in coordinating movements (the cerebellum) and controlling movements (the basal ganglia). Thus, the movement problems experienced by people with myoclonus-dystonia are caused by dysfunction in the brain, not the muscles. People with this condition show no signs of muscle disease. It is unknown why SGCE gene mutations seem only to affect the brain.
