What is (are) Benign schwannoma ? | Schwannomas are tumors of the tissue that covers the nerves (nerve sheath). These tumors develop from a type of cell called a Schwann cell, which gives these tumors their name. They are usually benign (not cancerous). Although schwannomas can arise from any nerve in the body, the most common areas include the nerves of the head and neck and those involved with moving the arms and legs. Common symptoms include a slow-growing mass and Tinel's sign (an electric-like shock when the affected area is touched). The cause of schwannomas is unknown, but they sometimes occur in people with certain disorders including some types of neurofibromatosis. Benign schwannomas are typically treated with surgery. | |
What are the symptoms of Benign schwannoma ? | What are the signs and symptoms of schwannomas? Common signs and symptoms of schwannomas include a slow-growing mass and Tinel shock (electric-like shock when affected area is touched). Some people may experience numbness or other neurological symptoms depending on the size and location of the tumor. | |
What causes Benign schwannoma ? | What causes schwannomas? The cause of schwannomas is unknown. They sometimes occur in people with certain disorders including some types of neurofibromatosis (neurofibromatosis type 2 and schwannomatosis). In these cases, affected people have multiple tumors that are due to changes (mutations) in a gene. For example, neurofibromatosis type 2 is caused by mutations in the NF2 gene and schwannomatosis is caused by mutations in the SMARCB1 gene and the LZTR1 gene. | |
Is Benign schwannoma inherited ? | Are schwannomas inherited? Most schwannomas are not inherited. The vast majority of schwannomas occur by chance (sporadically) and as a single tumor. In these cases, people typically do not have affected family members. Around 5-10% of people develop multiple schwannomas. In these cases, the schwannomas may be due to an inherited condition which can be passed from parent to child. For example, neurofibromatosis type 2 and schwannomatosis are two conditions known to cause multiple schwannomas. Both of these conditions are inherited in an autosomal dominant manner. This means that to be affected, a person only needs a change (mutation) in one copy of the responsible gene in each cell. In some cases, an affected person inherits the mutation from an affected parent. Other cases may result from new (de novo) mutations in the gene. These cases occur in people with no history of the disorder in their family. A person with neurofibromatosis type 2 or schwannomatosis has a 50% chance with each pregnancy of passing along the altered gene to his or her child. | |
How to diagnose Benign schwannoma ? | Is genetic testing available for schwannomas? Genetic testing is not available for many individuals with schwannomas since most of these tumors occur sporadically (by chance) and are not caused by a genetic mutation. However, genetic testing is an option for people with an inherited condition that predisposes to schwannomas such as certain types of neurofibromatosis (neurofibromatosis type 2 and schwannomatosis). Carrier testing for at-risk relatives and prenatal testing are possible if the disease-causing mutation in the family is known. The Genetic Testing Registry (GTR) is a centralized online resource for information about genetic tests. It provides a list of laboratories performing genetic testing for neurofibromatosis type 2 and schwannomatosis. The intended audience for the GTR is health care providers and researchers. Patients and consumers with specific questions about a genetic test should contact a health care provider or a genetics professional. How are schwannomas diagnosed? In addition to a complete physical exam and medical history, the following tests may be necessary to diagnose a schwannoma: x-ray, ultrasound, and/or magnetic resonance imaging (MRI). Some people may also need a biopsy of the tumor to confirm the diagnosis. | |
What are the treatments for Benign schwannoma ? | How might schwannoma be treated? The best treatment options for schwannoma depends on several factors, including the size and location of the tumor; whether the tumor is benign or malignant (cancerous); and the age and overall health of the affected person. For example, standard treatment for benign schwannomas is surgery to remove as much of the tumor as possible. People with malignant schwannomas may also be treated with radiation therapy and/or chemotherapy in addition to surgery. Because there is a chance that a schwannoma may return following surgery or treatment, regular follow-up with physical examinations and imaging should be discussed with a physician. | |
What is (are) Hantavirus pulmonary syndrome ? | Hantavirus pulmonary syndrome (HPS) is a severe, respiratory disease caused by infection with a hantavirus. People can become infected with a hantavirus through contact with hantavirus-infected rodents or their saliva, urine and/or droppings. Early symptoms universally include fatigue, fever and muscle aches (especially in the thighs, hips, and/or back), and sometimes include headaches, dizziness, chills, and abdominal problems such as nausea, vomiting, diarrhea, and pain. Later symptoms of the syndrome occur 4 to 10 days after initial onset and include coughing and shortness of breath. HPS can be fatal; approximately 38% of individuals with HPS do not survive. There is no cure or specific treatment for HPS, but early diagnosis and treatment in intensive care may increase the chance of recovery. | |
What is (are) Gaucher disease ? | Gaucher disease refers to a group of inherited conditions that affect many organs and tissues in the body. Signs and symptoms vary widely among affected individuals. There are different types of this condition: Gaucher disease perinatal lethal, Gaucher disease type 1, Gaucher disease type 2, and Gaucher disease type 3. Gaucher disease type 1 is the most common form of this condition. Gaucher disease is inherited in an autosomal recessive fashion and is caused by mutations in the GBA gene. | |

Much of this information comes from Orphanet, a European rare disease database. The frequency of a sign or symptom is usually listed as a rough estimate of the percentage of patients who have that feature. The frequency may also be listed as a fraction. The first number of the fraction is how many people had the symptom, and the second number is the total number of people who were examined in one study. For example, a frequency of 25/25 means that in a study of 25 people all patients were found to have that symptom. Because these frequencies are based on a specific study, the fractions may be different if another group of patients are examined. Sometimes, no information on frequency is available. In these cases, the sign or symptom may be rare or common. | |
What is (are) Ehlers-Danlos syndrome ? | Ehlers-Danlos syndrome (EDS) is a group of inherited connective tissue disorders that is caused by abnormalities in the structure, production, and/or processing of collagen. There are 6 major forms of EDS: hypermobility type, classic type, vascular type, kyphoscoliosis type, arthrochalasia type, and dermatosparaxis type. Although other forms of the condition exist, they are extremely rare and are not well-characterized. The signs and symptoms of EDS vary by type and range from mildly loose joints to life-threatening complications. Features shared by many types include joint hypermobility and soft, velvety skin that is highly elastic (stretchy) and bruises easily. Changes (mutations) in a variety of genes may lead to EDS; however, the underlying genetic cause in some families is unknown. Depending on the subtype, EDS may be inherited in an autosomal dominant or an autosomal recessive manner. There is no specific cure for EDS. The treatment and management is focused on preventing serious complications and relieving associated signs and symptoms. | |
What are the symptoms of Ehlers-Danlos syndrome ? | What are the signs and symptoms of Ehlers-Danlos syndrome? There are six major types of Ehlers-Danlos syndrome (EDS). Although there is significant overlap in associated features, the subtypes are classified based on their unique signs and symptoms: Hypermobility type - characterized primarily by joint hypermobility affecting both large (elbows, knees) and small (fingers, toes) joints which may lead to recurrent joint dislocations and subluxations (partial dislocation). Affected people generally experience skin involvement (soft, smooth and velvety skin with easy bruising) and chronic pain of the muscles and/or bones, as well. Classic type - associated with extremely elastic (stretchy), smooth skin that is fragile and bruises easily; wide, atrophic scars (flat or depressed scars); and joint hypermobility. Molluscoid pseudotumors (calcified hematomas over pressure points such as the elbow) and spheroids (fat-containing cysts on forearms and shins) are frequently diagnosed in affected people. Hypotonia and delayed motor development may occur, as well. Vascular type - characterized by thin, translucent skin that is extremely fragile and bruises easily. Arteries and certain organs such as the intestines and uterus are also fragile and prone to rupture. Affected people typically have short stature; thin scalp hair; and characteristic facial features including large eyes, a thin nose and lobeless ears. Joint hypermobility is present, but generally confined to the small joints (fingers, toes). Other common features include club foot; tendon and/or muscle rupture; acrogeria (premature aging of the skin of the hands and feet); early onset varicose veins; pneumothorax (collapse of a lung); gingival (gums) recession; and a decreased amount of subcutaneous (under the skin) fat. Kyphoscoliosis type - associated with severe hypotonia at birth, delayed motor development, progressive scoliosis (present from birth), and scleral fragility. Affected people may also have easy bruising; fragile arteries that are prone to rupture; unusually small cornia; and osteopenia (low bone density). Other common features include a "marfanoid habitus" which is characterized by long, slender fingers (arachnodactyly); unusually long limbs; and a sunken chest (pectus excavatum) or protruding chest (pectus carinatum). Arthrochalasia type - characterized by severe joint hypermobility and congenital hip dislocation. Other common features include fragile, elastic skin with easy bruising; hypotonia; kyphoscoliosis (kyphosis and scoliosis); and mild osteopenia. Dermatosparaxis type - associated with extremely fragile skin leading to severe bruising and scarring; saggy, redundant skin, especially on the face; and hernias. For more information on each subtype, please click on the links above. You can also find more detailed information on Medscape Reference's Web site or the Ehlers-Danlos National Foundation's Web site. Although other forms of the condition exist, they are extremely rare and are not well-characterized. | |
What causes Ehlers-Danlos syndrome ? | What causes Ehlers-Danlos syndrome? Ehlers-Danlos syndrome can be caused by changes (mutations) in several different genes (COL5A1, COL5A2, COL1A1, COL3A1, TNXB, PLOD1, COL1A2, and ADAMTS2). However, the underlying genetic cause is unknown in some families. Mutations in these genes usually alter the structure, production, and/or processing of collagen or proteins that interact with collagen. Collagen provides structure and strength to connective tissues throughout the body. A defect in collagen can weaken connective tissues in the skin, bones, blood vessels, and organs resulting in the features of the disorder. | |
Is Ehlers-Danlos syndrome inherited ? | Is Ehlers-Danlos syndrome inherited? The inheritance pattern of Ehlers-Danlos syndrome (EDS) varies by subtype. The arthrochalasia, classic, hypermobility, and vascular forms of the disorder usually have an autosomal dominant pattern of inheritance. This means that to be affected, a person only needs a change (mutation) in one copy of the responsible gene in each cell. In some cases, an affected person inherits the mutation from an affected parent. Other cases may result from new (de novo) mutations in the gene. These cases occur in people with no history of the disorder in their family. A person with one of these subtypes has a 50% chance with each pregnancy of passing along the altered gene to his or her child. The dermatosparaxis and kyphoscoliosis types of EDS are inherited in an autosomal recessive pattern. This means that to be affected, a person must have a mutation in both copies of the responsible gene in each cell. The parents of an affected person usually each carry one mutated copy of the gene and are referred to as carriers. Carriers typically do not show signs or symptoms of the condition. When two carriers of an autosomal recessive condition have children, each child has a 25% (1 in 4) risk to have the condition, a 50% (1 in 2) risk to be a carrier like each of the parents, and a 25% chance to not have the condition and not be a carrier. | |
How to diagnose Ehlers-Danlos syndrome ? | How is Ehlers-Danlos syndrome diagnosed? A diagnosis of Ehlers-Danlos syndrome is typically based on the presence of characteristic signs and symptoms. Depending on the subtype suspected, some of the following tests may be ordered to support the diagnosis: Collagen typing performed on a skin biopsy may aid in the diagnosis of vascular type, arthrochalasia type, and dermatosparaxis type. Collagen is a tough, fiber-like protein that makes up about a third of body protein. It is part of the structure of tendons, bones, and connective tissues. People with Ehlers-Danlos syndrome often have abnormalities of certain types of collagen. Genetic testing is available for many subtypes of Ehlers-Danlos syndrome; however, it is not an option for most families with the hypermobility type. Imaging studies such as CT scan, MRI, ultrasound, and angiography may be useful in identifying certain features of the condition. Urine tests to detect deficiencies in certain enzymes that are important for collagen formation may be helpful in diagnosing kyphoscoliosis type. | |
What are the treatments for Ehlers-Danlos syndrome ? | How might Ehlers-Danlos syndrome be treated? There is no specific cure for Ehlers-Danlos syndrome (EDS). The treatment and management is focused on preventing serious complications and relieving associated signs and symptoms. Because the features of EDS vary by subtype, management strategies differ slightly.

What are the treatments for Polyarteritis nodosa ? | How might polyarteritis nodosa be treated? Few people with polyarteritis nodosa have mild disease that remains stable with nonaggressive therapy; because of the risk for serious health complications, aggressive therapy is often recommended. Treatment may include prednisone in divided doses. Additional therapy, such as cyclophosphamide, chlorambucil, azathioprine, methotrexate, dapsone, cyclosporine, or plasma exchange, may also be recommended. The goal of therapy is remission (to have no active disease) within 6 months or so. At this point the person may be maintained on cyclophosphamide (or other therapy) for a year, before it is tapered and withdrawn over the course of 3 to 6 months.It is very important that people undergoing treatment for polyarteritis nodosa be monitored closely for toxic effects of the drugs or for signs of worsening disease. This monitoring may involve blood counts, urinalyses, serum chemistries, and the ESR on at least monthly intervals. | |

What is (are) Glucocorticoid-remediable aldosteronism ? | Glucocorticoid-remediable aldosteronism is one of three types of familial hyperaldosteronism and was first described in 1966. Aldosterone is a hormone manufactured by the adrenal glands which helps the body retain water and sodium and excrete potassium. It is caused by a fusion of the CYP11B1 and CYP11B2 genes and is inherited in an autosomal dominant manner. Individuals with this condition usually have hypertension (high blood pressure) before age 21. These individuals are also at an increased risk for a certain type of stroke known as a hemorrhagic stroke. First-line therapy consists of a steroid such as prednisone, dexamethasone, or hydrocortisone. This will often correct the overproduction of aldosterone, lower the blood pressure, and correct the potassium levels. | |

What is (are) Mowat-Wilson syndrome ? | Mowat-Wilson syndrome (MWS) is a rare genetic disorder that affects many systems of the body. The main features include moderate to severe intellectual disability, distinctive facial features, and epilepsy. Other features may include Hirschsprung disease; heart (cardiac) defects; kidney (renal) abnormalities; genital abnormalities; eye abnormalities; and short stature. It is caused by a mutation or deletion in the ZEB2 gene, which usually occurs for the first time (sporadically) in affected people. Treatment typically focuses on the specific symptoms in each person. | |

What causes Mowat-Wilson syndrome ? | What causes Mowat-Wilson syndrome? Mowat-Wilson syndrome is caused by mutations in the ZEB2 (also known as ZFHX1B or SIP-1) gene. This gene provides instructions for making a protein that plays a critical role in the formation of many organs and tissues before birth. It is a transcription factor, which means that it attaches (binds) to specific regions of DNA and helps control the activity of particular genes. Researchers believe that ZEB2 protein is involved in the development of tissues that give rise to the nervous system, digestive tract, facial features, heart, and other organs. Mowat-Wilson syndrome almost always results from the loss of one working copy of the ZEB2 gene in each cell. In some cases, the entire gene is deleted. In other cases, mutations within the gene lead to the production of an abnormally short, nonfunctional version of the ZEB2 protein. A shortage of this protein disrupts the normal development of many organs and tissues, which causes the varied signs and symptoms of Mowat-Wilson syndrome. | |
Is Mowat-Wilson syndrome inherited ? | How is Mowat-Wilson inherited? Mowat-Wilson syndrome is inherited in an autosomal dominant pattern, which means one copy of the altered gene in each cell is sufficient to cause the disorder. Most cases of Mowat-Wilson syndrome 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. | |

What is (are) Congenital radio-ulnar synostosis ? | Congenital radio-ulnar synostosis is a rare condition in which there is an abnormal connection (synostosis) of the radius and ulna (bones in the forearm) at birth. The condition is present in both arms (bilateral) in approximately 60% of cases. Signs and symptoms depend on the severity of the abnormality and whether it is bilateral; affected individuals often have limited rotational movement of the forearm. Pain is usually not present until the teenage years. It is due to abnormal fetal development of the forearm bones, but the underlying cause is not always known. It is sometimes a feature of certain chromosome abnormalities or genetic syndromes. Some cases appear to be inherited in an autosomal dominant manner. Treatment may be conservative or involve surgery depending on the severity of the abnormality and the range of movement. | |

What causes Congenital radio-ulnar synostosis ? | What causes congenital radio-ulnar synostosis? Congenital radio-ulnar synostosis is caused by abnormal development of the forearm bones in the fetal period, although the underlying cause of the developmental abnormality is not always known. The condition may be isolated (occur without other abnormalities) or it may be associated with various other skeletal, cardiac (heart), neurologic, or gastrointestinal abnormalities. When other abnormalities are present, the condition may be due to an underlying genetic cause, including a variety of syndromes or chromosome abnormalities. In some cases, congenital radio-ulnar synostosis appears to be inherited in an autosomal dominant manner. In an article published in 2000, the authors found that autosomal dominant radio-ulnar synostosis with amegakaryocytic thrombocytopenia was caused by mutations in the HOXA11 gene in 2 families. | |
Is Congenital radio-ulnar synostosis inherited ? | How is congenital radio-ulnar synostosis inherited? Congenital radio-ulnar synostosis appears to be inherited in an autosomal dominant manner in some cases. This means that one mutated copy of the disease-causing gene in each cell is sufficient to cause the condition. The mutated gene may occur for the first time in an affected individual, or it may be inherited from an affected parent. Each child of an individual with an autosomal dominant condition has a 50% (1 in 2) risk to inherit the mutated copy of the gene. Congenital radio-ulnar synostosis may also occur with a variety of other abnormalities and may be associated with a chromosome abnormality or genetic syndrome. In these cases, the inheritance pattern may depend upon that of the underlying genetic abnormality. Some genetic abnormalities that have been reported in association with this condition include Apert syndrome, Carpenter syndrome, arthrogryposis, Treacher Collins syndrome, Williams syndrome, Klinefelter syndrome, and Holt-Oram syndrome. Congenital radio-ulnar synostosis may also occur sporadically as an isolated abnormality, in which case the cause may be unknown. | |

What is (are) Muscular dystrophy, congenital, merosin-positive ? | The congenital muscle dystrophies are currently classified according to the genetic defects. Historically, congenital muscular dystrophies were classified in two broad groups: Classic CMD (which included the Merosin-deficient CMD and the Merosin-positive CMD) and the CMD with central nervous system (CNS) abnormalities (Fukuyama CMD, muscle-eye-brain disease and Walker-Warburg syndrome). Therefore, merosin-positive congenital muscle dystrophy (CMD) is now considered an old term which refers to a group of diseases without structural brain abnormalities that are caused by a variety of gene mutations, resulting in protein defects that do not affect the merosin protein. It usually has a milder phenotype than the merosin-negative CMD dystrophy group and includes, among others: Classic CMD without distinguishing features Rigid spine syndrome associated with mutations in the selenoprotein N1 gene (SEPN1) CMD with hyperextensible distal joints (Ullrich type) CMD with intellectual disability or sensory abnormalities. The pattern of muscle weakness and wasting in the patients within this group of congenital muscular dystrophy conditions is worse in the proximal upper limb-girdle and trunk muscles. Lower limb muscles may be mildly involved. Muscle biopsy shows a dystrophic pattern with normal staining for dystrophin, laminin alpha-2 of merosin and the sarcoglycans. | |

What is (are) Myelomeningocele ? | Myelomeningocele is the most severe form of spina bifida. It happens when parts of the spinal cord and nerves come through the open part of the spine. It causes nerve damage and other disabilities. Seventy to ninety percent of children with this condition also have too much fluid on their brains (hydrocephalus). This happens because fluid that protects the brain and spinal cord is unable to drain like it should. The fluid builds up, causing pressure and swelling. Without treatment, a persons head grows too big, and they may have brain damage. Other disorders of the spinal cord may be seen, including syringomyelia and hip dislocation. The cause of myelomeningocele is unknown. However, low levels of folic acid in a woman's body before and during early pregnancy is thought to play a part in this type of birth defect. | |
What are the symptoms of Myelomeningocele ? | What are the signs and symptoms of myelomeningocele? A baby born with a myelomeningocele may have a sac sticking out of the mid to lower back that the doctor cannot see through when shining a light behind it. Symptoms of this condition include:[5182] Loss of bladder or bowel control Partial or complete lack of sensation Partial or complete paralysis of the legs Weakness of the hips, legs, or feet Some individuals may have additional symptoms. Other symptoms include: Abnormal feet or legs, such as clubfoot. Build up of fluid inside the skull (hydrocephalus) Hair at the back part of the pelvis called the sacral area Dimpling of the sacral area Meningitis Chiari II malformation Twenty to 50 percent of children with myelomeningocele develop a condition called progressive tethering, or tethered cord syndrome. A part of the spinal cord becomes fastened to an immovable structuresuch as overlying membranes and vertebraecausing the spinal cord to become abnormally stretched and the vertebrae elongated with growth and movement. This condition can cause change in the muscle function of the legs, as well as changes in bowel and bladder function. Early surgery on the spinal cord may help the child to regain a normal level of functioning and prevent further neurological deterioration. | |
What are the treatments for Myelomeningocele ? | How might myelomeningocele be treated? A child with meningomyelocele usually has surgery to close the myelomenigocele shortly after birth. This prevents infections and helps save the spinal cord from more damage.[5181] Children who also have hydrocephalus may need a ventricular peritoneal shunt placed. This will help drain the extra fluid.[5182] In the United States, antibiotics, sac closure, and ventriculoperitoneal shunt placement are the standard of care and are implemented soon after birth in 93-95% of patients. | |

What causes MYH7-related scapuloperoneal myopathy ? | What causes MYH7-related scapuloperoneal myopathy? MYH7-related scapuloperoneal myopathy is caused by mutations in the MYH7 gene. This gene, located on chromosome 14q12, provides instructions for making a protein known as the cardiac beta ()-myosin heavy chain. This protein is found in heart (cardiac) muscle and in type I skeletal muscle fibers. Type I fibers, which are also known as slow-twitch fibers, are one of two types of fibers that make up skeletal muscles. Type I fibers are the primary component of skeletal muscles that are resistant to fatigue. For example, muscles involved in posture, such as the neck muscles that hold the head steady, are made predominantly of type I fibers. | |
What are the treatments for MYH7-related scapuloperoneal myopathy ? | How might scapuloperoneal myopathy be treated? There is no standard course of treatment for scapuloperoneal myopathy. Some patients may benefit from physical therapy or other therapeutic exercises. | |

What is (are) Rhabdoid tumor ? | Rhabdoid tumor (RT) is an aggressive pediatric soft tissue sarcoma that arises in the kidney, the liver, the peripheral nerves and all miscellaneous soft-parts throughout the body. RT involving the central nervous system (CNS) is called atypical teratoid rhabdoid tumor. RT usually occurs in infancy or childhood. In most cases, the first symptoms are linked to the compressive effects of a bulky tumor (such as respiratory distress, abdomen mass, peripheral nerve palsy). In about 90% of the cases it is caused by a mutation in the SMARCB1 gene, which is a tumor suppressor gene and in rare cases by a mutation in the SMARCA4 gene. No standard care exists for RT although there are a lot of studies. Treatment includes resection of the tumor mass and chemotherapy and radiotherapy. Because atypical teratoid rhabdoid tumors and rhabdoid tumors of the kidney have the same gene mutation and similar biopsy findings they are considered now identical or closely related entities. Also, 10-15% of patients with malignant rhabdoid tumors have brain tumors. | |

What is (are) BRCA1 hereditary breast and ovarian cancer syndrome ? | BRCA1 hereditary breast and ovarian cancer syndrome (BRCA1 HBOC) is an inherited condition that is characterized by an increased risk for a variety of different cancers. Women with this condition have a 57-60% risk of developing breast cancer, a 40-59% risk of developing ovarian cancer and an 83% risk of developing contralateral breast cancer by age 70. Men have a 1% lifetime risk of breast cancer and an increased risk for prostate cancer. BRCA1 HBOC may also be associated with an elevated risk for cancers of the cervix, uterus, pancreas, esophagus, stomach, fallopian tube, and primary peritoneum; however, these risks are not well defined. This condition is caused by changes (mutations) in the BRCA1 gene and is inherited in an autosomal dominant manner. Management may include high risk cancer screening, chemoprevention and/or prophylactic surgeries. | |

What is (are) CREST syndrome ? | CREST syndrome, also known as limited scleroderma, is a widespread connective tissue disease characterized by changes in the skin, blood vessels, skeletal muscles, and internal organs. The symptoms involved in CREST syndrome are associated with the generalized form of the disease systemic sclerosis (scleroderma). CREST is an acronym for the clinical features that are seen in a patient with this disease. (C) - Calcinosis (KAL-sin-OH-sis): the formation of calcium deposits in the connective tissues, which can be detected by X ray. They are typically found on the fingers, hands, face, trunk, and on the skin above the elbows and knees. When the deposits break through the skin, painful ulcers can result. (R) - Raynaud's (ray-NOHZ) phenomenon: a condition in which the small blood vessels of the hands and/or feet contract in response to cold or anxiety. As the vessels contract, the hands or feet turn white and cold, then blue. As blood flow returns, they become red. Fingertip tissues may suffer damage, leading to ulcers, scars, or gangrene. (E) - Esophageal (eh-SOFF-uh-GEE-ul) dysfunction: impaired function of the esophagus (the tube connecting the throat and the stomach) that occurs when smooth muscles in the esophagus lose normal movement. In the upper esophagus, the result can be swallowing difficulties; in the lower esophagus, the problem can cause chronic heartburn or inflammation. (S) - Sclerodactyly (SKLER-oh-DAK-till-ee): thick and tight skin on the fingers, resulting from deposits of excess collagen within skin layers. The condition makes it harder to bend or straighten the fingers. The skin may also appear shiny and darkened, with hair loss. (T) - Telangiectasia (tel-AN-jee-ek-TAY-zee-uhs): small red spots on the hands and face that are caused by the swelling of tiny blood vessels. While not painful, these red spots can create cosmetic problems. It is not necessary to have all five symptoms of CREST syndrome to be diagnosed with the disease. Some doctors believe only two of the five are necessary for a diagnosis. | |

What causes CREST syndrome ? | What causes CREST syndrome? In people with CREST syndrome, the immune system appears to stimulate cells called fibroblasts to produce excess amounts of collagen. Normally, fibroblasts synthesize collagen to help heal wounds, but in this case, the protein is produced even when it's not needed, forming thick bands of connective tissue around the cells of the skin, blood vessels and in some cases, the internal organs. Although an abnormal immune system response and the resulting production of excess collagen appears to be the main cause of limited scleroderma, researchers suspect that other factors may play a role, including: genetic factors, pregnancy, hormones, and environmental factors. | |
How to diagnose CREST syndrome ? | How is CREST syndrome diagnosed? CREST syndrome can be difficult to diagnose. Signs and symptoms vary widely and often resemble those of other connective tissue and autoimmune diseases. Further complicating matters is that limited scleroderma sometimes occurs with other autoimmune conditions such as polymyositis, lupus and rheumatoid arthritis. A blood sample can be tested for antibodies that are frequently found in the blood of people with limited scleroderma. But this isn't a definitive test because not everyone with limited scleroderma has these antibodies. Sometimes doctors take a small sample of skin that's then examined under a microscope in a laboratory. Biopsies can be helpful, but they can't definitively diagnose limited scleroderma either. Along with a blood test and skin biopsy, additional tests to identify lung, heart or gastrointestinal complications may also be conducted. | |

What causes Menetrier disease ? | What causes Mntrier disease? The exact cause of Mntrier disease is unknown. However, it has been associated with cytomegalovirus (CMV) infection in children and Heliobacter pylori (H. pylori) infection in adults. In addition, some have suggested that overexpression of a type of growth factor called the transforming growth factor-, which is found in a specific part of the stomach, the superficial gastric epithelium, might play a role. | |
What are the treatments for Menetrier disease ? | What treatment is available for Mntrier disease? No one treatment has proven effective for all patients with Mntrier disease; however, some benefit has been shown through the use of anticholinergic drugs, acid suppression, octreotide, and H. pylori eradication. Partial or complete removal of the stomach is generally recommended for those patients who continue to have protein loss or who have signs of pre-cancer or cancer.

What is (are) Hailey-Hailey disease ? | Hailey-Hailey disease is a hereditary blistering skin disease. Signs and symptoms include a painful rash and blistering in skin folds such as the armpits, groin, neck, under the breasts, and between the buttocks. Secondary bacterial infections are not uncommon. Symptoms are often worse in summer months due to heat, sweating and friction. Hailey-Hailey disease is caused by mutations in the ATP2C1 gene and is inherited in an autosomal dominant manner. Treatment focuses on reducing symptoms and preventing flares. | |

Is Hailey-Hailey disease inherited ? | How is Hailey-Hailey disease inherited? Hailey-Hailey disease is inherited in an autosomal dominant manner. This means that having only one mutated copy of the disease-causing gene in each cell is enough to cause signs or symptoms of the condition. Some people with Hailey-Hailey disease inherit the condition from an affected parent. Other cases are due to a new mutation in the gene and occur in people with no history of the condition in their family. When a person with an autosomal dominant condition has children, each child has a 50% (1 in 2) risk to inherit the mutated copy of the gene. | |
How to diagnose Hailey-Hailey disease ? | Is genetic testing available for Hailey-Hailey disease? Yes. ATP2C1 is the only gene known to be associated with Hailey-Hailey disease. Genetic testing is available to analyze the ATP2C1 gene for mutations.Genetic testing for at-risk relatives and prenatal testing are also possible if the disease-causing mutation in the family is known. How is Hailey-Hailey disease diagnosed? Diagnosis of Hailey-Hailey disease is usually made based on symptoms and family history. As it can be mistaken for other blistering skin conditions, a skin biopsy might be required. Genetic testing is available to confirm the diagnosis of Hailey-Hailey disease, but is not required. | |
What are the treatments for Hailey-Hailey disease ? | How might Hailey-Hailey disease be treated? There is no specific treatment for Hailey-Hailey disease and management generally focuses on the specific symptoms and severity in each person. Affected people are encouraged to avoid "triggers" such as sunburn, sweating, and friction, and to keep the affected areas dry. Sunscreen, loose clothing, moisturizing creams, and avoiding excessive heat may help prevent outbreaks. Trying to prevent bacterial, viral, and fungal infections in the affected areas is also important, and drugs used to treat or prevent these infections are commonly used. Topical medications (such as mild corticosteroid creams and topical antibiotics) may improve symptoms in milder forms. Cool compresses and dressings may also help. More severe cases may require systemic antibiotics and/or stronger corticosteroid creams. Carbon dioxide laser treatment may be effective for severe forms. In very severe cases, surgery can be performed to remove the affected skin, but skin grafts are usually necessary to repair the wounds. | |

What is (are) Hereditary sensory and autonomic neuropathy type V ? | Hereditary sensory and autonomic neuropathy type V (HSAN5) is a condition that affects the sensory nerve cells. These cells, which are also called sensory neurons, transmit information about sensations such as pain, temperature, and touch. Signs and symptoms of the condition generally develop at birth or during early infancy and may include a loss of pain and temperature sensation. Because of the inability to feel deep pain, affected people suffer repeated severe injuries such as bone fractures and joint injuries that go unnoticed. HSAN5 is caused by changes (mutations) in the NGF gene and is inherited in an autosomal recessive manner. Medical management is based on the signs and symptoms present in each person and is oriented to control hyperthermia (elevated body temperature) and prevent injury. | |

What is (are) Hereditary cerebral hemorrhage with amyloidosis ? | Cerebral amyloid angiopathy (CAA) is a neurological condition in which amyloid protein is deposited onto the walls of the arteries of the brain (and less frequently, veins). Although CAA often does not cause symptoms, it may cause bleeding into the brain (hemorrhagic stroke), dementia, or neurologic episodes in some patients. The majority of CAA cases occur in individuals who do not have a family history. However, two familial forms of CAA have been identified. | |
What are the symptoms of Hereditary cerebral hemorrhage with amyloidosis ? | What symptoms may be associated with hereditary cerebral hemorrhage with amyloidosis - Dutch type? Approximately 87% of individuals with hereditary cerebral hemorrhage with amyloidosis - Dutch type have intracranial hemorrhage (bleeding in the brain) and 13% have infarcts (stroke). The first stroke usually occurs between the ages of 45 and 65 years, and is not caused by hypertension or hemorrhagic diathesis (bleeding tendency). Nausea, vomiting, progressive headache, focal neurological signs (double or decreased vision, speech difficulties, confusion, delirium, weakness or paralysis, sensation changes or loss of sensation, progressive intellectual deterioration and memory disturbance) and impairment of consciousness are the most frequent signs and symptoms. Psychiatric abnormalities, including dementia are also common, with some patients developing dementia without intracranial hemorrhage. | |
What causes Hereditary cerebral hemorrhage with amyloidosis ? | What causes hereditary cerebral hemorrhage with amyloidosis - Dutch type? The clinical symptoms of hereditary cerebral hemorrhage with amyloidosis - Dutch type are caused by the build-up of a protein called amyloid within the arterial walls of the brain. This protein build-up causes bleeding into the brain. The symptoms occur because bleeding in the brain harms brain tissue. Hereditary cerebral hemorrhage with amyloidosis-Dutch type is an autosomal dominant disorder with complete penetrance (all individuals who inherit the mutated gene will develop the condition). The likely genetic defect is in the amyloid protein precursor protein (APP) gene on chromosome 21. | |
Is Hereditary cerebral hemorrhage with amyloidosis inherited ? | Since I have a family history of hereditary cerebral hemorrhage with amyloidosis, what are the chances that I inherited the condition? To find out your chances of having hereditary cerebral hemorrhage with amyloidosis, you may want to speak with a genetics professional. A genetics professionl can review your medical and family history in order to provide you with your specific risks. To learn more about genetic consultations, click here. | |
What are the treatments for Hereditary cerebral hemorrhage with amyloidosis ? | How might hereditary cerebral hemorrhage with amyloidosis - Dutch type be treated? There is no known effective treatment for hereditary cerebral hemorrhage with amyloidosis - Dutch type. Treatment is supportive and based on the control of symptoms. In some cases, rehabilitation is needed for weakness or clumsiness. This can include physical, occupational, or speech therapy. Occasionally, some patients are good candidates for medications that can help improve memory. The management of intracranial hemorrhage (ICH) related to hereditary cerebral hemorrhage with amyloidosis - Dutch type is identical to the standard management of ICH. The main objectives include reversing anticoagulation, managing intracranial pressure, and preventing complications. | |

What is (are) Neurofibromatosis type 1 ? | Neurofibromatosis type 1 (NF1) is a rare, inherited condition that is characterized primarily by changes in skin coloring and the development of multiple benign tumors along the nerves of the skin, brain, and other parts of the body. The severity of the condition and the associated signs and symptoms vary significantly from person to person. NF1 is caused by changes (mutations) in the NF1 gene and is inherited in an autosomal dominant manner. In approximately 50% of cases, the condition is inherited from an affected parent. Other cases may result from new (de novo) mutations in the gene which occur in people with no history of the condition in their family. Treatment is based on the signs and symptoms present in each person. | |
What are the symptoms of Neurofibromatosis type 1 ? | What are the signs and symptoms of Neurofibromatosis type 1? People affected by neurofibromatosis type 1 (NF1) have an increased risk of developing many different types of tumors (both cancerous and noncancerous). Almost all people with NF1 have neurofibromas, which are benign tumors that can affect nearly any nerve in the body. Most will develop these tumors on or just underneath the skin; however, neurofibromas can also grow in other places in the body and may even affect multiple nerves. Malignant peripheral nerve sheath tumors, which also grow along the nerves throughout the body, are the most common cancerous tumor found in people with NF1 and occur in approximately 10% of affected people. In children with NF1, the most common tumors are optic glioma (tumors that grow along the nerve leading from the eye to the brain) and brain tumors. Optic gliomas associated with NF1 are often asymptomatic although they can lead to vision loss. Other features of NF1 may include: Caf au lait spots (flat patches on the skin that are darker than the surrounding area) Freckling, especially in the underarm and groin Lisch nodules (clumps of pigment in the colored part of the eye that do not interfere with vision) Learning disabilities Seizures Autism spectrum disorder High blood pressure Short stature An unusually large head (macrocephaly) Skeletal abnormalities such as scoliosis GeneReview's Web site offers more specific information about the features of NF1.

What causes Neurofibromatosis type 1 ? | What causes neurofibromatosis type 1? Neurofibromatosis type 1 is caused by changes (mutations) in the NF1 gene. NF1 is a tumor suppressor gene, which means that it encodes a protein that stops cells from growing and dividing too rapidly or in an uncontrolled way. Mutations in NF1 result in an abnormal protein that is unable to carry out its normal role. This contributes to the development of the many different types of tumors found in neurofibromatosis type 1. People with neurofibromatosis type 1 are typically born with one mutated copy of the NF1 gene in each cell and are, therefore, genetically predisposed to develop the tumors associated with the condition. For a tumor to form, two copies of the NF1 gene must be altered. The mutation in the second copy of the NF1 gene is considered a somatic mutation because it occurs during a person's lifetime and is not inherited. Almost everyone who is born with one NF1 mutation acquires a second mutation in many cells and develops the tumors characteristic of neurofibromatosis type 1. | |
Is Neurofibromatosis type 1 inherited ? | How is neurofibromatosis type 1 inherited? Neurofibromatosis type 1 (NF1) is inherited in an autosomal dominant manner. This means that a person only needs a change (mutation) in one copy of the responsible gene in each cell to have a genetic predisposition to the tumors associated with NF1. In approximately half of cases, an affected person inherits the mutation from an affected parent. Other cases may result from new (de novo) mutations in the gene; these cases occur in people with no history of the disorder in their family. A person with NF1 has a 50% chance with each pregnancy of passing along the altered gene to his or her child. | |
How to diagnose Neurofibromatosis type 1 ? | Is genetic testing available for neurofibromatosis type 1? Although it is usually not necessary for diagnosis, genetic testing is available for NF1, the gene known to cause neurofibromatosis type 1. Carrier testing for at-risk relatives and prenatal testing are possible if the disease-causing mutation in the family is known. The Genetic Testing Registry (GTR) is a centralized online resource for information about genetic tests. The intended audience for the GTR is health care providers and researchers. Patients and consumers with specific questions about a genetic test should contact a health care provider or a genetics professional. How is neurofibromatosis type 1 diagnosed? The diagnosis of neurofibromatosis type 1 (NF1) is usually based on the presence of characteristic signs and symptoms. Specifically, doctors look for two or more of the following features to make a diagnosis of NF1: Six or more cafe-au-lait spots (measuring more than 5 mm across in children and more than 15 mm across in adolescents and adults) Two or more neurofibromas of any type or one plexiform neurofibroma (a neurofibroma that involves many nerves) Freckling in the underarm and/or groin Optic glioma Two or more Lisch nodules (clumps of pigment in the colored part of the eye that do not interfere with vision) Bone abnormalities including sphenoid dysplasia (absence of bone surrounding the eye) or tibial pseudarthrosis (incomplete healing of a fracture) A parent, sibling, or child who has been diagnosed with NF1 Because many of the features associated with NF1 develop with age, it can sometimes take several years to make a diagnosis in children without a family history of the condition. Genetic testing for changes (mutations) in the NF1 gene is available, but it is often not necessary. Prenatal testing and preimplantation genetic diagnosis is only an option if the disease-causing mutation in the family is known. | |
What are the treatments for Neurofibromatosis type 1 ? | How might neurofibromatosis type 1 be treated? The treatment of neurofibromatosis type 1 (NF1) is based on the signs and symptoms present in each person. There is currently no way to prevent or stop the growth of the tumors associated with NF1. Neurofibromas located on or just below the skin that are disfiguring or irritating may be surgically removed. Malignant peripheral nerve sheath tumors are generally treated with complete surgical excision (when possible) although some cases may require the addition of chemotherapy and/or radiation therapy. Most optic gliomas associated with NF1 do not cause any symptoms and therefore, do not require treatment; however, optic gliomas that threaten vision may be treated with surgery and/or chemotherapy. Surgery may also be recommended to correct some of the bone malformations (such as scoliosis) associated with NF1. GeneReview's Web site offers more specific information regarding the treatment and management of NF1. Please click on the link to access this resource. | |
What is (are) Pigmented villonodular synovitis ? | Pigmented villonodular synovitis (PVNS) is a disease in which the tissue lining the joints and tendons in the body (synovium) grows abnormally. It is characterized by a noncancerous mass or tumor. There are two types of PVNS: the local or nodular form (where the tumor involves the tendons that support the joint, or in one area of the joint) and the diffuse form (where the entire lining of the joint is involved). Symptoms might include: pain, limitation of movement, and locking of the joint. In some cases, the normal joint structure can be destroyed. The knee is most commonly affected by this condition, though it can occur in other joints such as the hip, shoulder, elbow, ankle, wrist, and rarely the jaw. The average age of diagnosis for this condition is 35 years. The cause of PVNS is grossly unknown. Treatment involves surgery to remove the tumor and damaged portions of the synovium. |
