Question:  What is (are) Schwannomatosis ?
Answer: Schwannomatosis is a rare form of neurofibromatosis that is primarily characterized by multiple schwannomas (benign tumors of the nervous system) in the absence of bilateral (affecting both sides) vestibular schwannomas. Signs and symptoms of the condition vary based on the size, location and number of schwannomas but may include pain; numbness; tingling; and/or weakness in the fingers and toes. Inherited forms of the disorder account for only 15 percent of all cases. In some of these families, schwannomatosis is caused by changes (mutations) in the SMARCB1 or LZTR1 genes; in other cases, the exact underlying cause is unknown. When inherited, the condition is passed down in an autosomal dominant manner with highly variable expressivity and reduced penetrance. Treatment is based on the signs and symptoms present in each person but may include medications and/or surgery.
Question:  What are the symptoms of Schwannomatosis ?
Answer: What are the signs and symptoms of Schwannomatosis? Signs and symptoms of the schwannomatosis often develop during adulthood between ages 25 and 30. Affected people generally have multiple schwannomas, which are benign tumors of the nervous system. In schwannomatosis, these tumors can grow along any nerve in the body, although they are less common on the vestibular nerve (vestibular schwannomas, also known as acoustic neuromas). People with vestibular schwannomas, especially those with tumors affecting the vestibular nerve on both sides of the head (bilateral), may have neurofibromatosis type 2 instead. The signs and symptoms associated with schwannomatosis vary based on the size and location of the schwannomas. The most common symptom is chronic pain, which can develop as a growing schwannoma presses on nerves or surrounding tissues. Some people may develop a mass if the schwannomas is located just beneath the skin. Others can experience neurological symptoms such as numbness; tingling; and/or weakness in the fingers and toes. The Human Phenotype Ontology provides the following list of signs and symptoms for Schwannomatosis. If the information is available, the table below includes how often the symptom is seen in people with this condition. You can use the MedlinePlus Medical Dictionary to look up the definitions for these medical terms. Signs and Symptoms Approximate number of patients (when available) Abnormality of the skin - Abnormality of the vertebral column - Autosomal dominant inheritance - Incomplete penetrance - Meningioma - Schwannoma - Somatic mutation - Spinal cord tumor - Variable expressivity - The Human Phenotype Ontology (HPO) has collected information on how often a sign or symptom occurs in a condition. 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.
Question:  What causes Schwannomatosis ?
Answer: What causes schwannomatosis? Some cases of schwannomatosis are caused by changes (mutations) in the SMARCB1 or LZTR1 genes. SMARCB1 and LZTR1 are tumor suppressor genes, which means that they encode a protein that stops cells from growing and dividing too rapidly or in an uncontrolled way. Mutations in these genes result in abnormal proteins that are unable to carry out their normal roles. This contributes to the development of the many different types of tumors found in schwannomatosis. When schwannomatosis is caused by a mutation in SMARCB1 or LZTR1, the affected person is typically born with one mutated copy of the gene in each cell and is, therefore, genetically predisposed to develop the tumors associated with the condition. For a tumor to form, two copies of the gene must be altered. The mutation in the second copy of the gene is considered a somatic mutation because it occurs during a person's lifetime and is not inherited. In affected people without a mutation in SMARCB1 or LZTR1, the underlying cause of the condition is unknown.
Question:  Is Schwannomatosis inherited ?
Answer: Is schwannomatosis inherited? Approximately 15% percent of all schwannomatosis cases are thought to be inherited. In these cases, the condition is thought to be inherited in an autosomal dominant manner with highly variable expressivity and reduced penetrance. 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 schwannomatosis. 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. People with an inherited form of schwannomatosis have a 50% chance with each pregnancy of passing the condition on to the next generation.
Question:  How to diagnose Schwannomatosis ?
Answer: How is schwannomatosis diagnosed? A diagnosis of schwannomatosis is often suspected based on the presence of characteristic signs and symptoms, especially if there are other family members with the condition. Additional testing can then be ordered to further support the diagnosis and rule out other conditions with similar features (namely, neurofibromatosis type 2). This may include: Tumor pathology confirming that the growths are, in fact, schwannomas Imaging studies, such as an MRI examining the vestibular nerve. It is important to rule out the presence of bilateral (affecting both sides) vestibular schwannomas which would be suggestive of neurofibromatosis type 2 rather than schwannomatosis Genetic testing for a change (mutation) in the SMARCB1 or LZTR1 genes. Unfortunately, genetic testing is not informative in all people affected by schwannomatosis.
Question:  What are the treatments for Schwannomatosis ?
Answer: How might schwannomatosis be treated? Treatment for schwannomatosis is based on the signs and symptoms present in each person. For example, pain is one of the most common symptoms of the condition. Treatment with medications such as gabapentin or pregabalin and the use of short-acting opioids and/or nonsteroidal anti-inflammatories for pain can be successful for many patients. If pain cannot be managed with other means or if the schwannomas are causing other symptoms, they can be surgically removed. However this treatment is often used as a last resort because surgery may put patients at risk of further neurologic problems.
Question:  What is (are) Usher syndrome, type 1B ?
Answer: Usher syndrome is a genetic condition characterized by hearing loss or deafness, and progressive vision loss due to retinitis pigmentosa. Three major types of Usher syndrome have been described - types I, II, and III.  The different types are distinguished by their severity and the age when signs and symptoms appear. All three types are inherited in an autosomal recessive manner, which means both copies of the disease-causing gene in each cell have mutations.
Question:  What are the symptoms of Usher syndrome, type 1B ?
Answer: What are the signs and symptoms of Usher syndrome, type 1B? The Human Phenotype Ontology provides the following list of signs and symptoms for Usher syndrome, type 1B. If the information is available, the table below includes how often the symptom is seen in people with this condition.

Question:  Is Usher syndrome, type 1B inherited ?
Answer: How is Usher syndrome inherited? Usher syndrome is inherited in an autosomal recessive manner. This means that a person must have a change (mutation) in both copies of the disease-causing gene in each cell to have Usher syndrome. One mutated copy is typically inherited from each parent, who are each referred to as a carrier. Carriers of an autosomal recessive condition usually do not have any signs or symptoms. When two carriers of an autosomal recessive condition have children, each child has a 25% (1 in 4) chance to have the condition, a 50% (1 in 2) chance to be an unaffected carrier like each parent, and a 25% chance to not be a carrier and not be affected.
Question:  What is (are) Split hand split foot malformation autosomal recessive ?
Answer: Split hand foot malformation (SHFM) is a type of birth defect that consists of missing digits (fingers and/or toes), a deep cleft down the center of the hand or foot, and fusion of remaining digits. The severity of this condition varies widely among affected individuals. SHFM is sometimes called ectrodactyly; however, this is a nonspecific term used to describe missing digits. SHFM may occur by itself (isolated) or it may be part of a syndrome with abnormalities in other parts of the body. At least six different forms of isolated SHFM have been described. Each type is associated with a different underlying genetic cause. SHFM1 has been linked to chromosome 7, and SHFM2 is linked to the X chromosome. SHFM3 is caused by a duplication of chromosome 10 at position 10q24. Changes (mutations) in the TP63 gene cause SHFM4. SHFM5 is linked to chromosome 2, and SHFM6 is caused by mutations in the WNT10B gene. SHFM may be inherited in an autosomal dominant, autosomal recessive, or X-linked manner.

Question:  What is (are) Catamenial pneumothorax ?
Answer: Catamenial pneumothorax is an extremely rare condition that affects women. Pneumothorax is the medical term for a collapsed lung, a condition in which air or gas is trapped in the space surrounding the lungs causing the lungs to collapse. Women with catamenial pneumothorax have recurrent episodes of pneumothorax that occur within 72 hours before or after the start of menstruation. The exact cause of catamenial pneumothorax is unknown and several theories have been proposed. Many cases are associated with the abnormal development of endometrial tissue outside of the uterus (endometriosis). Some believe that catamenial pneumothorax is the most common form of thoracic endometriosis (a condition in which the endometrial tissue grows in or around the lungs). A diagnosis of catamenial pneumothorax is usually suspected when a woman of reproductive age and with endometriosis has episodes of pneumothorax. Treatment is with hormones and surgery.
Question:  What are the symptoms of Catamenial pneumothorax ?
Answer: What are the signs and symptoms of Catamenial pneumothorax? The Human Phenotype Ontology provides the following list of signs and symptoms for Catamenial pneumothorax.

Question:  What causes Catamenial pneumothorax ?
Answer: What causes catamenial pneumothorax? The exact cause is not known. However, spontaneous collapse of the lung (pneumothorax) occurs in 72% to 73% of cases of thoracic endometriosis. Thoracic endometriosis is a condition in which endometrial tissue is present in the chest (thoracic) cavity. It is more often seen in women who are about 34 years old. Thoracic endometriosis can be found in most cases of catamenial pneumothorax. Pneumothorax associated with endometriosis may also occur without being related with menstruation (non-catamenial pneumothorax) even in cases with no symptoms or without diagnosis of pelvic endometriosis.
Question:  How to diagnose Catamenial pneumothorax ?
Answer: How might catamenial pneumothorax be diagnosed? The diagnosis should be suspected in women of reproductive age who have several episodes of spontaneous lung collapse (pneumothoraces) and have endometriosis. Medical thoracoscopy or video-assisted thoracoscopy may confirm the diagnosis.
Question:  What are the treatments for Catamenial pneumothorax ?
Answer: How might catamenial pneumothorax be treated? Treatment of choice is with surgery, with video-assisted thoracoscopic surgery (VATS). Conventional thoracotomy may be occasionally necessary, particularly in repeat operations. It is very important to examine the large, thin tissue lining around the outside of the lungs and the inside of the chest cavity (pleura).  Hormonal treatment with surgery prevents the repeat of catamenial and/or endometriosis-related pneumothorax. Gonadotrophin-releasing hormone (GnRH) for 6 to 12 months after the surgery is also often recommended.
Question:  What is (are) Peyronie disease ?
Answer: Peyronie disease is a connective tissue disorder characterized by a plaque, or hard lump, that forms within the penis. Affected individuals may experience painful, curved erections which can make make normal sexual intercourse impossible. Symptoms may appear suddenly or develop gradually. While the painful erections for most men resolve over time, the scar tissue and curvature may remain. Some cases appear to resolve spontaneously. The exact cause of Peyronie's disease is not known.

Question:  What is (are) Congenital mirror movement disorder ?
Answer: Congenital mirror movement disorder (CMM) is a rare condition that is characterized by mirror movements (involuntary movements of one side of the body that mirror intentional movements on the opposite side). Affected people generally develop these movements in infancy or early childhood, which usually persist throughout their life without any related signs or symptoms. In most cases, the involuntary movements are noticeable but less pronounced than the corresponding voluntary movements; however, the severity of symptoms can vary significantly, even among family members. CMM can be caused by changes (mutations) in the DCC or RAD51 genes and inherited in an autosomal dominant manner. In some families, the exact underlying cause of CMM is unknown.
