user: What are the symptoms of Muir-Torre syndrome ?

assistant: What are the signs and symptoms of Muir-Torre syndrome? Sebaceous adenoma is the most characteristic finding in people with Muir-Torre syndrome (MTS). Other types of skin tumors in affected people include sebaceous epitheliomas, sebaceous carcinomas (which commonly occur on the eyelids) and keratoacanthomas. Sebaceous carcinoma of the eyelid can invade the orbit of the eye and frequently metastasize, leading to death. Tumors at other sites can also metastasize, but are less likely to cause death. Common sites of keratocathomas include the face and the upper side of the hands, but they can occur anywhere on the body. The most common internal cancer in people with MTS is colorectal cancer, occurring in almost half of affected people. The second most common site is the genitourinary tract. Other cancers that may occur include breast cancer, lymphoma, leukemia (rarely), salivary gland tumors, lower and upper respiratory tract tumors, and chondrosarcoma. Intestinal polyps as well as various benign tumors may also occur. The Human Phenotype Ontology provides the following list of signs and symptoms for Muir-Torre syndrome. 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.

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.
user: What causes Muir-Torre syndrome ?

assistant: What causes Muir-Torre syndrome? Muir-Torre syndrome is a subtype of Lynch syndrome and may be caused by changes (mutations) in either the MLH1, MSH2, or MSH6 gene. These genes give the body instructions to make proteins needed for repairing DNA. The proteins help fix mistakes that are made when DNA is copied before cells divide. When one of these genes is mutated and causes the related protein to be absent or nonfunctional, the number of DNA mistakes that do not get repaired increases substantially. The affected cells do not function normally, increasing the risk of tumor formation. The MSH2 gene is responsible for MTS in the majority of cases. Mutations in MLH1 and MSH2 have the most severe effect. Not everyone diagnosed with MTS will have a detectable mutation in one of these genes. Other, unidentified genes may also play a role in the development of the condition.
user: Is Muir-Torre syndrome inherited ?

assistant: How is Muir-Torre syndrome inherited? Muir-Torre-syndrome (MTS) is a variant of Lynch syndrome and is inherited in an autosomal dominant manner. This means that having only one changed (mutated) copy of the responsible gene in each cell is enough for a person to develop the condition. When a person with an autosomal dominant condition has children, each child has 50% (1 in 2) chance to inherit the mutated copy of the responsible gene. It is important to note that people who inherit a mutated gene that causes MTS inherit an increased risk of cancer, not the disease itself. Not all people who inherit a mutation in an associated gene will develop cancer. This phenomenon is called reduced penetrance. The majority of people diagnosed with a form of Lynch syndrome have inherited the mutated gene from a parent. However, because not all people with a mutation develop cancer, and the variable age at which cancer may develop, not all people with a mutation have a parent who had cancer. Thus, the family history may appear negative. A positive family history of MTS is identified in roughly 50% of affected people. The percentage of people with Lynch syndrome who have a new mutation in the gene that occurred for the first time (and was not inherited from a parent) is unknown but is estimated to be extremely low.
user: How to diagnose Muir-Torre syndrome ?

assistant: How is Muir-Torre syndrome diagnosed? A person is suspected to have Muir-Torre syndrome (MTS)if he/she has one or more of the following: History of one or more sebaceous tumors Age younger than 60 years at first presentation of sebaceous tumors Personal history of Lynch-related cancers Family history of Lynch-related cancers The presence of specific skin tumors in MTS may lead to the correct diagnosis even in the absence of a clear family history. A person diagnosed with MTS can also have genetic testing to see if they have a mutation in one of the genes known to cause MTS. However, not everyone with Muir-Torre syndrome will have a detectable mutation in one of these genes. Other, unidentified genes may also play a role in the development of the condition.

user: What is (are) Schwannomatosis ?

assistant: 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.
user: What are the symptoms of Schwannomatosis ?

assistant: 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.

user: What causes Schwannomatosis ?

assistant: 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.
user: Is Schwannomatosis inherited ?

assistant: 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.
user: How to diagnose Schwannomatosis ?

assistant: 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.
user: What are the treatments for Schwannomatosis ?

assistant: 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.

user: What is (are) Sideroblastic anemia ?

assistant: Sideroblastic anemia is a heterogeneous group of blood disorders characterized by an impaired ability of the bone marrow to produce normal red blood cells. The iron inside red blood cells is inadequately used to make hemoglobin, despite adequate or increased amounts of iron. Abnormal red blood cells called sideroblasts are found in the blood of people with these anemias. Sideroblastic anemias are classified as hereditary, acquired, and reversible.
user: What are the symptoms of Sideroblastic anemia ?

assistant: What are the symptoms of sideroblastic anemia? The symptoms of sideroblastic anemia are the same as for any anemia and iron overload. These may include fatigue, weakness, palpitations, shortness of breath, headaches, irritability, and chest pain. Physical findings may include pallor, tachycardia, hepatosplenomegaly, S3 gallop, jugular vein distension, and rales.
user: What causes Sideroblastic anemia ?

assistant: What causes sideroblastic anemia? The exact cause of sideroblastic anemia in many patients remains unknown. Reversible sideroblastic anemia can be caused by alcohol, isoniazid, pyrazinamide, cycloserine (a prescription antibiotic that may cause anemia, peripheral neuritis, or seizures by acting as a pyridoxine antagonist or increasing excretion of pyridoxine), chloramphenicol, or copper deficiency. The hereditary forms may be passed through families in autosomal recessive, autosomal dominant, or X-linked patterns.
user: How to diagnose Sideroblastic anemia ?

assistant: How is sideroblastic anemia diagnosed? The principle feature of sideroblastic anemia is slowly progressive, mild, life-long anemia which often goes unnoticed. Symptoms of iron overload may lead to the discovery of this underlying disorder. The history and clinical findings, together with laboratory findings, usually permit accurate diagnosis of each type. Laboratory evaluation may include complete blood count, iron studies, free erythrocyte protoporphyrin levels, MRI, bone marrow aspiration and liver biopsy. Molecular defects can be identified in several hereditary forms and in some patients with acquired sideroblastic anemia.
user: What are the treatments for Sideroblastic anemia ?

assistant: How might sideroblastic anemia be treated? The treatment of sideroblastic anemia is directed at controlling symptoms of anemia and preventing organ damage from iron overload. Many patients see improvement with increased vitamin B6 intake - either through diet (potatoes, bananas, raisin bran cereal, lentils, liver, turkey, and tuna are good sources) or supplements - with red blood cell counts returning to near-normal values. Folic acid supplementation may also be beneficial. Those that do not respond to vitamin supplementation require blood transfusion.  A few small studies have described the use of allogenic bone marrow or stem cell transplantation for hereditary and congenital forms of sideroblastic anemia. While these therapies may offer the possibility of a cure, the complications associated with transplantation surgery must be considered.  All patients with sideroblastic anemia should be followed by a hematologist and avoid alcohol.
user: What is (are) Rett syndrome ?

assistant: Rett syndrome is a progressive, neuro-developmental condition that primarily affects girls. Affected girls appear to have normal psychomotor development during the first 6 to 18 months of life, followed by a developmental "plateau," and then rapid regression in language and motor skills. Additional signs and symptoms may include repetitive, stereotypic hand movements; fits of screaming and inconsolable crying; autistic features; panic-like attacks; teeth grinding (bruxism); episodic apnea and/or hyperpnea; gait ataxia and apraxia; tremors; seizures; and slowed head growth. Some people have an atypical form of Rett syndrome that may be more mild or more severe. Classic Rett syndrome is most commonly caused by mutations in the MECP2 gene and is usually inherited in an X-linked dominant manner. The vast majority of cases are not inherited from a parent, but are due to a new mutation in the affected person. Treatment mainly focuses on the specific signs and symptoms of the condition.
