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.
As with multiple sclerosis, the course and prognosis of Schilder's disease are unpredictable. For some individuals the disorder is progressive with a steady, unremitting course. Others may experience significant improvement and even remission. In some cases, Schilder's disease is fatal.
An ectopic kidney is a birth defect in which a kidney is located below, above, or on the opposite side of its usual position. About one in 900 people has an ectopic kidney.1
How might sideroblastic anemia pyridoxine-refractory autosomal recessive be treated? Currently there is not a cure for sideroblastic anemia pyridoxine-refractory autosomal recessive, however with proper treatment the life-expectancy of people with this anemia can be close to normal. Treatments are aimed at preventing organ damage from iron overload, and controlling symptoms of anemia. People with severe anemia may require periodic transfusions. Transfusions of red cells are kept to a minimum, to avoid accelerating iron overload. Treatment of iron overload involves an iron depletion program, such as therapeutic phlebotomy or iron chelation. Total splenectomy is contraindicated in this disorder. This form of sideroblastic anemia is not associated with an increased risk for leukemia. 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.
Trimethylaminuria is a disorder in which the body is unable to break down trimethylamine, a chemical compound that has a pungent odor. Trimethylamine has been described as smelling like rotting fish, rotting eggs, garbage, or urine. As this compound builds up in the body, it causes affected people to give off a strong odor in their sweat, urine, and breath. The intensity of the odor may vary over time. The odor can interfere with many aspects of daily life, affecting a person's relationships, social life, and career. Some people with trimethylaminuria experience depression and social isolation as a result of this condition.
In areas where rodent reservoirs and tick species are prevalent, people with recreational or occupational exposure to rural or outdoor settings (e.g., hunters, campers, forest workers, farmers) are potentially at increased risk for OHF by contact with infected ticks and animals. Furthermore, those in Siberia who hunt and trap muskrats specifically are at higher risk for OHF. Exposure may also occur in the laboratory environment.
Lenz microphthalmia syndrome is a very rare condition; its incidence is unknown. It has been identified in only a few families worldwide.
The National Institute of Neurological Disorders and Stroke (NINDS) supports research related to cerebellar hypoplasia and its associated disorders through grants to major research institutions across the country. Much of this research focuses on finding better ways to prevent, treat, and ultimately cure disorders that feature cerebellar hypoplasia.
A desirable level for total cholesterol is less than 200 mg/dL. Here are the ranges for total cholesterol levels. Do you know how your total cholesterol level compares?
Brown-Sequard syndrome is a rare neurological condition characterized by a lesion in the spinal cord. This condition results in weakness or paralysis on one side of the body (hemiparaplegia) and a loss of sensation on the opposite side (hemianesthesia). Brown-Sequard syndrome may be caused by a spinal cord tumor, trauma (such as a puncture wound to the neck or back), obstructed blood vessel, or infectious or inflammatory diseases such as tuberculosis, or multiple sclerosis. Treatment and prognosis depends on the underlying cause of the condition.
Combined oxidative phosphorylation deficiency 16, also know as infantile hypertrophic cardiomyopathy, is characterized by decreased levels of mitochondrial complexes. The symptoms and signs described include an enlarged heart muscle (hypertrophic cardiomyopathy) and fatty liver (hepatic steatosis), as well as eye problems, headache, paralysis of one side of the body, Leigh-like lesions on brain magnetic resonance imaging (MRI), kidney insufficiency and neurological disease. It is caused by mutations in the MRPL44 gene, which results in mitochondrial dysfunction. The cases described seem to be inherited in an autosomal recessive pattern. Treatment is supportive.
Most people with indigestion experience more than one of the following symptoms: - Fullness during a meal. The person feels overly full soon after the meal starts and cannot finish the meal. - Bothersome fullness after a meal. The person feels overly full after a mealit may feel like the food is staying in the stomach too long. - Epigastric pain. The epigastric area is between the lower end of the chest bone and the navel. The person may experience epigastric pain ranging from mild to severe. - Epigastric burning. The person feels an unpleasant sensation of heat in the epigastric area. Other, less frequent symptoms that may occur with indigestion are nausea and bloatingan unpleasant tightness in the stomach. Nausea and bloating could be due to causes other than indigestion. Sometimes the term indigestion is used to describe the symptom of heartburn, but these are two different conditions. Heartburn is a painful, burning feeling in the chest that radiates toward the neck or back. Heartburn is caused by stomach acid rising into the esophagus and may be a symptom of GERD. A person can have symptoms of both indigestion and heartburn.
Spinocerebellar ataxia 3 is a rare movement disorder that is characterized by ataxia, clumsiness and weakness in the arms and legs, spasticity, a staggering lurching walk easily mistaken for drunkenness, difficulty with speech and swallowing, and involuntary eye movements sometimes accompanied by double vision, and bulging eyes. Some patients have dystonia or symptoms similar to those of Parkinson's disease. Others have twitching of the face or tongue, neuropathy, or problems with urination and the autonomic nervous system. Symptoms can begin any time between childhood and about 70 years of age. Spinocerebellar ataxia 3 is a progressive disease, meaning that symptoms get worse with time. Life expectancy ranges from the mid-thirties for those with severe forms of the disorder to a normal life expectancy for those with mild forms. Spinocerebellar ataxia is inherited in an autosomal dominant pattern and is caused by a trinucleotide repeat expansion in the ataxin-3 gene (ATXN3).
Signs and symptoms of adult ALL include fever, feeling tired, and easy bruising or bleeding. The early signs and symptoms of ALL may be like the flu or other common diseases. Check with your doctor if you have any of the following: - Weakness or feeling tired. - Fever or night sweats. - Easy bruising or bleeding. - Petechiae (flat, pinpoint spots under the skin, caused by bleeding). - Shortness of breath. - Weight loss or loss of appetite. - Pain in the bones or stomach. - Pain or feeling of fullness below the ribs. - Painless lumps in the neck, underarm, stomach, or groin. - Having many infections. These and other signs and symptoms may be caused by adult acute lymphoblastic leukemia or by other conditions.
How might Norum disease be treated? Symptomatic treatment for anemia, renal insufficiency, and atherosclerosis is indicated. LCAT gene therapy or liver transplantation theoretically would be a treatment of choice to correct the underlying pathophysiology, but neither procedure has been reported. Short-term whole blood or plasma transfusion has been tried to replace the LCAT enzyme in some patients with familial LCAT deficiency, but it did not correct anemia, proteinuria, or lipoprotein abnormalities. Renal replacement by dialysis is necessary in those individuals who develop kidney failure. Kidney transplantation is indicated in patients with familial LCAT deficiency and renal failure. Corneal transplantation is indicated in patients with corneal opacities with severely reduced vision. Restriction of fat intake may be advisable in patients with familial LCAT deficiency, but no evidence supports its potential benefits. Because of the small but measurable risk of atherosclerosis in persons with LCAT deficiency, exercise, under the guidance of a physician, theoretically would have a role in prevention of this complication.
What are the signs and symptoms of Kallmann syndrome 6? The Human Phenotype Ontology provides the following list of signs and symptoms for Kallmann syndrome 6. 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) Anosmia 7.5% Autosomal dominant inheritance - Hypogonadotrophic hypogonadism - 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.
The worldwide prevalence of SCA6 is estimated to be less than 1 in 100,000 individuals.
Hyperprolinemia type 2 results in an excess of a particular protein building block (amino acid), called proline, in the blood. This condition generally occurs when proline is not broken down properly by the body. Hyperprolinemia type 2 causes proline levels in the blood to be 10 to 15 times higher than normal, and it also causes high levels of a related compound called pyrroline-5-carboxylate. Some people with this condition develop mild mental retardation and seizures; however, the symptoms of this disorder vary in severity among affected individuals.
Mutations in the CLCN1 gene cause myotonia congenita. The CLCN1 gene provides instructions for making a protein that is critical for the normal function of skeletal muscle cells. For the body to move normally, skeletal muscles must tense (contract) and relax in a coordinated way. Muscle contraction and relaxation are controlled by the flow of charged atoms (ions) into and out of muscle cells. Specifically, the protein produced from the CLCN1 gene forms a channel that controls the flow of negatively charged chlorine atoms (chloride ions) into these cells. The main function of this channel is to stabilize the cells' electrical charge, which prevents muscles from contracting abnormally. Mutations in the CLCN1 gene alter the usual structure or function of chloride channels. The altered channels cannot properly regulate ion flow, reducing the movement of chloride ions into skeletal muscle cells. This disruption in chloride ion flow triggers prolonged muscle contractions, which are the hallmark of myotonia.

The problems of gastroparesis can include - severe dehydration due to persistent vomiting - gastroesophageal reflux disease (GERD), which is GER that occurs more than twice a week for a few weeks; GERD can lead to esophagitis irritation of the esophagus - bezoars, which can cause nausea, vomiting, obstruction, or interfere with absorption of some medications in pill form - difficulty managing blood glucose levels in people with diabetes - malnutrition due to poor absorption of nutrients or a low calorie intake - decreased quality of life, including work absences due to severe symptoms
When a hazardous chemical has been released, it may harm people's health. Chemical releases can be unintentional, as in the case of an industrial accident. They could also be planned, as in the case of a terrorist attack with a chemical weapon. Some hazardous chemicals have been developed by military organizations for use in warfare. Examples are nerve agents such as sarin and VX. Many hazardous chemicals are used in industry - for example, chlorine, ammonia, and benzene. Some can be made from everyday items such as household cleaners. Although there are no guarantees of safety during a chemical emergency, you can take actions to protect yourself. You should have a disaster plan. Being prepared can help reduce fear, anxiety, and losses. If you do experience a disaster, it is normal to feel stressed. You may need help in finding ways to cope.

Acquired cystic kidney disease differs from PKD in several ways. Unlike acquired cystic kidney disease, PKD is a genetic, or inherited, disorder that can cause complications such as high blood pressure and problems with blood vessels in the brain and heart. The following chart lists the differences: People with Polycystic Kidney Disease - are born with a gene that causes the disease - have enlarged kidneys - develop cysts in the liver and other parts of the body People with Acquired Cystic Kidney Disease - do not have a disease-causing gene - have kidneys that are normal-sized or smaller - do not form cysts in other parts of the body In addition, for people with PKD, the presence of cysts marks the onset of their disease, while people with acquired cystic kidney disease already have CKD when they develop cysts. More information is provided in the NIDDK health topic, Polycystic Kidney Disease.
While acute pain is a normal sensation triggered in the nervous system to alert you to possible injury and the need to take care of yourself, chronic pain is different. Chronic pain persists. Pain signals keep firing in the nervous system for weeks, months, even years. There may have been an initial mishap -- sprained back, serious infection, or there may be an ongoing cause of pain -- arthritis, cancer, ear infection, but some people suffer chronic pain in the absence of any past injury or evidence of body damage. Many chronic pain conditions affect older adults. Common chronic pain complaints include headache, low back pain, cancer pain, arthritis pain, neurogenic pain (pain resulting from damage to the peripheral nerves or to the central nervous system itself), psychogenic pain (pain not due to past disease or injury or any visible sign of damage inside or outside the nervous system). A person may have two or more co-existing chronic pain conditions. Such conditions can include chronic fatigue syndrome, endometriosis, fibromyalgia, inflammatory bowel disease, interstitial cystitis, temporomandibular joint dysfunction, and vulvodynia. It is not known whether these disorders share a common cause.
Anyone can develop glaucoma. Some people are at higher risk than others. They include - African-Americans over age 40 - everyone over age 60, especially Hispanics/Latinos - people with a family history of glaucoma. African-Americans over age 40 everyone over age 60, especially Hispanics/Latinos people with a family history of glaucoma. See this graphic for a quick overview of glaucoma, including how many people it affects, whos at risk, what to do if you have it, and how to learn more.
What are the signs and symptoms of Chronic myeloid leukemia? The Human Phenotype Ontology provides the following list of signs and symptoms for Chronic myeloid leukemia. 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) Chronic myelogenous leukemia - Ph-positive acute lymphoblastic leukemia - Somatic mutation - The Human Phenotype Ontology (HPO) has collected information on how often a sign or symptom occurs in a condition.

In these cases, the sign or symptom may be rare or common.
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.
Summary : Noise is all around you, from televisions and radios to lawn mowers and washing machines. Normally, you hear these sounds at safe levels that don't affect hearing. But sounds that are too loud or loud sounds over a long time are harmful. They can damage sensitive structures of the inner ear and cause noise-induced hearing loss. More than 30 million Americans are exposed to hazardous sound levels on a regular basis. Hazardous sound levels are louder than 80 decibels. That's not as loud as traffic on a busy street. Listening to loud music, especially on headphones, is a common cause of noise-induced hearing loss. You can protect your hearing by - Keeping the volume down when listening to music - Wearing earplugs when using loud equipment NIH: National Institute on Deafness and Other Communication Disorders
Mutations in the ABCB7 gene cause X-linked sideroblastic anemia and ataxia. The ABCB7 gene provides instructions for making a protein that is critical for heme production. Heme is a component of the hemoglobin protein, which is vital for supplying oxygen to the entire body. The ABCB7 protein also plays a role in the formation of certain proteins containing clusters of iron and sulfur atoms. Overall, researchers believe that the ABCB7 protein helps maintain an appropriate balance of iron (iron homeostasis) in developing red blood cells. ABCB7 mutations slightly alter the structure of the ABCB7 protein, disrupting its usual role in heme production and iron homeostasis. Anemia results when heme cannot be produced normally, and therefore not enough hemoglobin is made. It is unclear how changes in the ABCB7 gene lead to ataxia and other problems with movement.
COACH syndrome is a condition that mainly affects the brain and liver. Most individuals with COACH syndrome have mental retardation, liver problems (fibrosis), and difficulty with movement (ataxia). Some may also have an abnormality of the eye (called a coloboma) or abnormal eye movements (such as nystagmus). This condition is inherited in an autosomal recessive manner; 70% of cases are thought to be caused by mutations in the TMEM67 gene. COACH syndrome is considered a rare form of another condition, Joubert syndrome.
Simple forms of myoclonus occur in normal, healthy persons and cause no difficulties. In some cases, myoclonus begins in one region of the body and spreads to muscles in other areas. More severe cases of myoclonus can distort movement and severely limit a person's ability to eat, talk, or walk. These types of myoclonus may indicate an underlying disorder in the brain or nerves. Although clonazepam and sodium valproate are effective in the majority of people with myoclonus, some people have adverse reactions to these drugs. The beneficial effects of clonazepam may diminish over time if the individual develops a tolerance for the drug.
How might porokeratosis of Mibelli be treated? Treatment depends on the size, location, and aggressiveness of porokeratosis of Mibelli. Affected individuals are recommended to visit their personal physician regularly to watch for signs of skin cancer, limit sun exposure to the affected area, and use moisturizers as needed. Imiquimod cream has been found to be an effective treatment, as has 5-fluorouracil cream. A group of medications called retinoids (including acitretin and isotretinoin), as a pill or cream, may be another treatment option. If a skin cancer develops from porokeratosis of Mibelli, surgery is recommended.
Horizontal gaze palsy with progressive scoliosis (HGPPS) is a disorder that affects vision and also causes an abnormal curvature of the spine (scoliosis). People with this condition are unable to move their eyes side-to-side (horizontally). As a result, affected individuals must turn their head instead of moving their eyes to track moving objects. Up-and-down (vertical) eye movements are typically normal. In people with HGPPS, an abnormal side-to-side curvature of the spine develops in infancy or childhood. It tends to be moderate to severe and worsens over time. Because the abnormal spine position can be painful and interfere with movement, it is often treated with surgery early in life.
What causes congenital bilateral absence of the vas deferens (CBAVD)? More than half of all men with CBAVD have mutations in the CFTR gene. Mutations in this gene also cause cystic fibrosis. When CBAVD occurs with CFTR mutations, it is considered a form of atypical cystic fibrosis. In instances of CBAVD without a mutation in the CFTR gene, the cause of this condition is often unknown. Some cases are associated with other structural problems of the urinary tract.
Aarskog-Scott syndrome is inherited in an X-linked recessive pattern. The gene associated with this condition is located on the X chromosome, which is one of the two sex chromosomes. In males (who have only one X chromosome), one altered copy of the gene in each cell is sufficient to cause the condition. In females (who have two X chromosomes), a mutation would have to occur in both copies of the gene to cause Aarskog-Scott syndrome. Because it is unlikely that females will have two altered copies of this gene, males are affected by X-linked recessive disorders much more frequently than females. Females who carry one altered copy of the FGD1 gene may show mild signs of the condition, such as hypertelorism, short stature, or a widow's peak hairline. A characteristic of X-linked inheritance is that fathers cannot pass X-linked traits to their sons.
What treatments are available for oculocutaneous albinism? Individuals with oculocutaneous albinism should have annual skin examinations to check for skin damage or skin cancer and annual eye examination to check vision. Affected individuals should cover their skin from sun exposure by using sunscreen and wearing protective clothing such as long-sleeve shirts, long pants, and hats with wide brims. Glasses may be worn to reduce sensitivity to bright light or to improve vision. Additional therapies or surgery may be used to treat crossed eyes (strabismus) or rapid eye movements (nystagmus).
Is multifocal motor neuropathy inherited? We are not aware of any evidence that multifocal motor neuropathy (MMN) is inherited or of any reports of familial cases (occurring in more than one person in a family). Furthermore, to our knowledge, no specific genes known to be associated with MMN have been identified.
What are the early signs of lymphomatoid papulosis? Patients may present with multiple skin papules (raised bumps) that can occur anywhere on the body but most often on the chest, stomach, back, arms, and legs. The papules appear in crops and may be mildly itchy. They may develop into blood or pus-filled blisters that break and form a crusty sore before healing completely. Lesions tend to spontaneously heal with or without scarring within 2-8 weeks of appearing.

Idiopathic pulmonary fibrosis has an estimated prevalence of 13 to 20 per 100,000 people worldwide. About 100,000 people are affected in the United States, and 30,000 to 40,000 new cases are diagnosed each year. Familial pulmonary fibrosis is less common than the sporadic form of the disease. Only a small percentage of cases of idiopathic pulmonary fibrosis appear to run in families.
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.
A dendritic cell tumor develops from the cells of the immune system. This condition typically begins in the lymph system and may spread to nearby organs or distant parts of the body (metastasize). There are five subtypes of dendritic cell tumors: follicular dendritic cell tumor, interdigitating dendritic cell tumor, Langerhans' cell histiocytosis, Langerhans' cell sarcoma, and dendritic cell sarcoma not specified otherwise. The symptoms and severity of the condition depend on the subtype and location of the tumor. Treatment may include surgery, radiation therapy, and/or chemotherapy.
Trisomy 17 mosaicism is a chromosomal abnormality in which there are three copies of chromosome 17 in some cells of the body, rather than the usual two copies. Trisomy 17 mosaicism is one of the rarest trisomies in humans. It is often incorrectly called trisomy 17 (also referred to as full trisomy 17), which is when three copies of chromosome 17 are present in all cells of the body. Full trisomy 17 has never been reported in a living individual in the medical literature. Few cases of trisomy 17 mosaicism have been described, most having been detected during pregnancy through a test called amniocentesis. Only a few individuals have had a confirmed diagnosis of trisomy 17 mosaicism after birth. Because the proportion and location of cells with trisomy 17 differs from case to case, the presence and severity of signs and symptoms may vary significantly from person to person.
What causes Nance-Horan syndrome? Nance-Horan syndrome is caused by a mutation in the NHS gene, which is located on the X chromosome. Some patients have losses (deletions) of part of the chromosome X short arm (p) within the region involving the NHS gene and other genes that are located in this region. These patients may have more problems and the problems may be more serious.
The most common symptom of dry AMD is slightly blurred vision. You may have difficulty recognizing faces. You may need more light for reading and other tasks. Dry AMD generally affects both eyes, but vision can be lost in one eye while the other eye seems unaffected. One of the most common early signs of dry AMD is drusen. Drusen are yellow deposits under the retina. They often are found in people over age 50. Your eye care professional can detect drusen during a comprehensive dilated eye exam.
Every year, approximately 30 cases of poisoning by marine toxins are reported in the United States. Because healthcare providers are not required to report these illnesses and because many milder cases are not diagnosed or reported, the actual number of poisonings may be much greater. Toxic seafood poisonings are more common in the summer than winter because dinoflagelates grow well in warmer seasons. It is estimated from cases with available data that one person dies every 4 years from toxic seafood poisonings.
What causes hyper IgM syndrome? A flawed gene (or genes) in T-cells (a type of white blood cell that is part of the immune system and helps the body fight diseases or harmful substances) is responsible for hyper IgM syndrome. The faulty T-cells do not give B-cells a signal they need to switch from making IgM to IgA and IgG. Most cases (approximately 70%) of hyper-IgM syndrome are linked to a recessive mutation on the X chromosome. These cases are inherited as an X-linked recessive genetic trait. Because males do not have a second, healthy, X-chromosome to offset the disease, boys far out number girls with this disease. A small number of cases of hyper IgM syndrome have been attributed to autosomal recessive and autosomal dominant genetic inheritance. In addition, a rare acquired form of the disorder has been described in the medical literature.
Multiple endocrine neoplasia, type 1 (MEN1) is an inherited condition that causes tumors of the endocrine system (the body's network of hormone-producing glands). People affected by MEN1 typically develop tumors of the parathyroid gland, the pituitary gland, and the pancreas, although other glands may be involved as well. These tumors are often "functional" and secrete excess hormones, which can cause a variety of health problems. The most common signs and symptoms of MEN1 are caused by hyperparathyroidism (overactive parathyroid gland) and may include kidney stones; thinning of bones; nausea and vomiting; high blood pressure (hypertension); weakness; and fatigue. MEN1 is caused by changes (mutations) in the MEN1 gene and is inherited in an autosomal dominant manner. Management for MEN1 usually includes regular screening to allow for early diagnosis and treatment of endocrine tumors.
Intrahepatic cholestasis of pregnancy (ICP) is a disorder of the liver that occurs in women during pregnancy. Cholestasis is a condition that impairs the release of bile (a digestive juice) from liver cells. The bile then builds up in the liver, impairing liver function. Symptoms typically become apparent in the third trimester of pregnancy and can include severe itching (pruritus). Occasionally, the skin and the whites of the eyes can have a yellow appearance (jaundice). ICP is additionally associated with risks to the developing baby such as premature delivery and stillbirth. The cause of ICP is largely unknown, although approximately 15% of cases are caused by mutations in either the ABCB11 or ABCB4 genes. Mutations within the ABCB11 and ABCB4 genes are inherited in an autosomal dominant manner. Symptoms of ICP are typically limited to pregnancy. Bile flow returns to normal after delivery and the signs and symptoms of the condition disappear, however, they can return during later pregnancies.
This condition is inherited in an autosomal dominant pattern, which means one copy of the altered ATP1A3 gene in each cell is sufficient to cause the disorder. In most cases, an affected person inherits a mutation from one affected parent. Other cases result from new mutations in the gene and occur in people with no history of the disorder in their family. Not everyone who has an ATP1A3 mutation will ultimately develop the signs and symptoms of rapid-onset dystonia parkinsonism. It is unclear why some people with a gene mutation develop movement abnormalities and others do not.
Myoclonic epilepsy with ragged red fibers (MERRF) is a multisystem disorder characterized by myoclonus, which is often the first symptom, followed by generalized epilepsy, ataxia, weakness, and dementia. Symptoms usually first appear in childhood or adolescence after normal early development. The features of MERRF vary widely from individual to individual, even within families. Other common findings include hearing loss, short stature, optic atrophy, and cardiomyopathy with Wolff-Parkinson-White (WPW) syndrome. The diagnosis is based on clinical features and a muscle biopsy finding of ragged red fibers (RRF). In over 80% of cases, MERRF is caused by mutations in the mitochondrial gene called MT-TK. Several other mitochondrial genes have also been reported to cause MERRF, but many of the individuals with mutations in these other genes have additional signs and symptoms. Seizures associated with MERRF are generally treated with conventional anticonvulsant therapy. Coenzyme Q10 and L-carnitine are often used with the hope of improving mitochondrial function.

This condition is inherited in an autosomal dominant pattern, which means one copy of the altered SALL4 gene in each cell is sufficient to cause the disorder. In many cases, an affected person inherits a mutation from one affected parent. Other cases result from new mutations in the gene and occur in people with no history of the disorder in their family.
In most cases, symptoms of NF1 are mild, and individuals live normal and productive lives. In some cases, however, NF1 can be severely debilitating and may cause cosmetic and psychological issues. The course of NF2 varies greatly among individuals. Loss of hearing in both ears develops in most individuals with NF2. In some cases of NF2, the damage to nearby vital structures, such as other cranial nerves and the brain stem, can be life-threatening. Most individuals with schwannomatosis have significant pain. In some extreme cases the pain will be severe and disabling.

Skin cancer is caused by DNA damage, which can result from excess exposure to ultraviolet (UV) light. Having a previous occurrence of skin cancer or a close family member with the disease also puts you at risk for skin cancer. Other risk factors include having - a weak immune system - unusual moles or a large number of moles - white or light (fair)-colored skin, especially with freckles - blond or red hair or blue or green eyes - scars or burns on the skin, or skin diseases that make someone sensitive to the sun. a weak immune system unusual moles or a large number of moles white or light (fair)-colored skin, especially with freckles blond or red hair or blue or green eyes scars or burns on the skin, or skin diseases that make someone sensitive to the sun. In 2008 the National Cancer Institute developed a Melanoma Risk Tool which can help patients and their doctors determine their risk. The tool can be found at http://www.cancer.gov/melanomarisktool/.
What causes hypophosphatasia? Hypophosphatasia (HPP) is a genetic condition caused by mutations in the ALPL gene. This gene gives the body instructions to make an enzyme called alkaline phosphatase, which is needed for mineralization of the bones and teeth. Mutations in this gene lead to an abnormal version of the enzyme, thus affecting the mineralization process. A shortage of the enzyme also causes other substances to build up in the body. These abnormalities lead to the features of HPP. ALPL mutations that almost completely eliminate alkaline phosphatase activity generally cause the more severe forms of HPP, while mutations that reduce activity to a lesser extent often cause the milder forms of HPP.
Acral peeling skin syndrome is caused by mutations in the TGM5 gene. This gene provides instructions for making an enzyme called transglutaminase 5, which is a component of the outer layer of skin (the epidermis). Transglutaminase 5 plays a critical role in the formation of a structure called the cornified cell envelope, which surrounds epidermal cells and helps the skin form a protective barrier between the body and its environment. TGM5 gene mutations reduce the production of transglutaminase 5 or prevent cells from making any of this protein. A shortage of transglutaminase 5 weakens the cornified cell envelope, which allows the outermost cells of the epidermis to separate easily from the underlying skin and peel off. This peeling is most noticeable on the hands and feet probably because those areas tend to be heavily exposed to moisture and friction.
Drugs to specifically treat Alzheimers disease and some other progressive dementias are now available. Although these drugs do not halt the disease or reverse existing brain damage, they can improve symptoms and slow the progression of the disease. This may improve an individuals quality of life, ease the burden on caregivers, or delay admission to a nursing home. Many researchers are also examining whether these drugs may be useful for treating other types of dementia. Many people with dementia, particularly those in the early stages, may benefit from practicing tasks designed to improve performance in specific aspects of cognitive functioning. For example, people can sometimes be taught to use memory aids, such as mnemonics, computerized recall devices, or note taking.
Genetics is one of the most exciting areas of Parkinson's disease research. Studying the genes responsible for inherited cases can help researchers understand both inherited and sporadic cases of the disease. Sporadic means the disease occurs randomly and does not seem to run in families. Identifying gene defects can also help researchers - understand how the disease occurs - develop animal models that accurately mimic the death of nerve cells in human Parkinson's disease - identify new drug targets - improve diagnosis. understand how the disease occurs develop animal models that accurately mimic the death of nerve cells in human Parkinson's disease identify new drug targets improve diagnosis.
Is Tietze syndrome inherited? Tietze syndrome is not thought to be inherited. Most cases occur sporadically in people with no family history of the condition.
Signs of GTD include abnormal vaginal bleeding and a uterus that is larger than normal. These and other signs and symptoms may be caused by gestational trophoblastic disease or by other conditions. Check with your doctor if you have any of the following: - Vaginal bleeding not related to menstruation. - A uterus that is larger than expected during pregnancy. - Pain or pressure in the pelvis. - Severe nausea and vomiting during pregnancy. - High blood pressure with headache and swelling of feet and hands early in the pregnancy. - Vaginal bleeding that continues for longer than normal after delivery. - Fatigue, shortness of breath, dizziness, and a fast or irregular heartbeat caused by anemia. GTD sometimes causes an overactive thyroid. Signs and symptoms of an overactive thyroid include the following: - Fast or irregular heartbeat. - Shakiness. - Sweating. - Frequent bowel movements. - Trouble sleeping. - Feeling anxious or irritable. - Weight loss.
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.
Norum disease is an autosomal recessive disorder of lipoprotein metabolism that causes a typical triad of diffuse corneal opacities, target cell hemolytic anemia, and proteinuria with renal (kidney) failure. Two clinical forms are recognized: familial LCAT deficiency and fish-eye disease. Familial LCAT deficiency is associated with a complete absence of alpha and beta LCAT activities and results in esterification anomalies involving both HDL (alpha-LCAT activity) and LDL (beta-LCAT activity).
Dry mouth can be uncomfortable. Some people notice a sticky, dry feeling in the mouth. Others notice a burning feeling or difficulty while eating. The throat may feel dry, too, and swallowing without extra fluids can often be difficult. Also, people with dry mouth may develop mouth sores, cracked lips, and a dry, rough tongue.
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.
Senior-Lken syndrome is a rare disorder characterized by the combination of two specific features: a kidney condition called nephronophthisis and an eye condition known as Leber congenital amaurosis. Nephronophthisis causes fluid-filled cysts to develop in the kidneys beginning in childhood. These cysts impair kidney function, initially causing increased urine production (polyuria), excessive thirst (polydipsia), general weakness, and extreme tiredness (fatigue). Nephronophthisis leads to end-stage renal disease (ESRD) later in childhood or in adolescence. ESRD is a life-threatening failure of kidney function that occurs when the kidneys are no longer able to filter fluids and waste products from the body effectively. Leber congenital amaurosis primarily affects the retina, which is the specialized tissue at the back of the eye that detects light and color. This condition causes vision problems, including an increased sensitivity to light (photophobia), involuntary movements of the eyes (nystagmus), and extreme farsightedness (hyperopia). Some people with Senior-Lken syndrome develop the signs of Leber congenital amaurosis within the first few years of life, while others do not develop vision problems until later in childhood.
- Fecal incontinence, also called a bowel control problem, is the accidental passing of solid or liquid stool or mucus from the rectum. Fecal incontinence includes the inability to hold a bowel movement until reaching a toilet as well as passing stool into ones underwear without being aware of it happening. - Nearly 18 million U.S. adultsabout one in 12have fecal incontinence. People with fecal incontinence should not be afraid or embarrassed to talk with their health care provider. - Fecal incontinence has many causes, including - diarrhea - constipation - muscle damage or weakness - nerve damage - loss of stretch in the rectum - childbirth by vaginal delivery - hemorrhoids and rectal prolapse - rectocele - inactivity - Health care providers diagnose fecal incontinence based on a persons medical history, physical exam, and medical test results. - Treatment for fecal incontinence may include one or more of the following: - eating, diet, and nutrition - medications - bowel training - pelvic floor exercises and biofeedback - surgery - electrical stimulation - A food diary can help identify foods that cause fecal incontinence. - Fecal incontinence can occur in children because of a birth defect or disease, but in most cases it occurs because of constipation.
What are the signs and symptoms of Achard syndrome? The Human Phenotype Ontology provides the following list of signs and symptoms for Achard 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. Signs and Symptoms Approximate number of patients (when available) Arachnodactyly - Autosomal dominant inheritance - Brachycephaly - Broad skull - Joint laxity - 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.
Your liver is the largest organ inside your body. It helps your body digest food, store energy, and remove poisons. Primary liver cancer starts in the liver. Metastatic liver cancer starts somewhere else and spreads to your liver. Risk factors for primary liver cancer include - Having hepatitis B or C - Heavy alcohol use - Having cirrhosis, or scarring of the liver - Having hemochromatosis, an iron storage disease - Obesity and diabetes Symptoms can include a lump or pain on the right side of your abdomen and yellowing of the skin. However, you may not have symptoms until the cancer is advanced. This makes it harder to treat. Doctors use tests that examine the liver and the blood to diagnose liver cancer. Treatment options include surgery, radiation, chemotherapy, or liver transplantation. NIH: National Cancer Institute
More than 34 million American adults have elevated blood cholesterol levels (higher than 240 mg/dL). Inherited forms of hypercholesterolemia, which cause even higher levels of cholesterol, occur less frequently. The most common inherited form of high cholesterol is called familial hypercholesterolemia. This condition affects about 1 in 500 people in most countries. Familial hypercholesterolemia occurs more frequently in certain populations, including Afrikaners in South Africa, French Canadians, Lebanese, and Finns.
How might periventricular nodular heterotopia be treated? Treatment of epilepsy generally follows principles for a seizure disorder caused by a known structural brain abnormality; carbamezipine is most often used, because most patients have focal seizures. However, antiepileptic drugs may be selected based on side effects, tolerability, and efficacy. It is recommended that patients with the X-linked form of the disease have studies evaluating the carotid artery and an abdominal ultrasound because of the risk for aortic or carotid dissection or other vascular anomalies.[1823] Treatment also include surgery for removal of the lesion and more recently, laser ablation guided with magnetic resonance.
This condition is inherited in an autosomal codominant pattern. Codominance means that two different versions of the gene may be active (expressed), and both versions contribute to the genetic trait. The most common version (allele) of the SERPINA1 gene, called M, produces normal levels of alpha-1 antitrypsin. Most people in the general population have two copies of the M allele (MM) in each cell. Other versions of the SERPINA1 gene lead to reduced levels of alpha-1 antitrypsin. For example, the S allele produces moderately low levels of this protein, and the Z allele produces very little alpha-1 antitrypsin. Individuals with two copies of the Z allele (ZZ) in each cell are likely to have alpha-1 antitrypsin deficiency. Those with the SZ combination have an increased risk of developing lung diseases (such as emphysema), particularly if they smoke. Worldwide, it is estimated that 161 million people have one copy of the S or Z allele and one copy of the M allele in each cell (MS or MZ). Individuals with an MS (or SS) combination usually produce enough alpha-1 antitrypsin to protect the lungs. People with MZ alleles, however, have a slightly increased risk of impaired lung or liver function.
MNT is the use of nutrition counseling by a registered dietitian to help promote a medical or health goal. A health care provider may refer a patient to a registered dietitian to help with the patient's food plan. Many insurance policies cover MNT when recommended by a health care provider. Anyone who qualifies for Medicare can receive a benefit for MNT from a registered dietitian or nutrition professional when a health care provider provides a referral indicating that the person has diabetes or kidney disease. One way to locate a qualified dietitian is to contact the Academy of Nutrition and Dietetics at www.eatright.organd click on "Find a Registered Dietitian." Users can enter their address or ZIP code for a list of dietitians in their area. A person looking for dietary advice to prevent kidney damage should click on "Renal (Kidney) Nutrition" in the specialty field. Dietitians who specialize in helping people with CKD are called renal dietitians. Top

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. In most cases, an affected person inherits the mutation from one affected parent. Other cases result from new mutations in the gene and occur in people with no history of the disorder in their family.
Osteoporosis does not have any symptoms until a fracture occurs. Some people may be unaware that they have already experienced one or more spine fractures. Height loss of one inch or more may be the first sign that someone has experienced spinal fractures due to osteoporosis. People who have experienced a fracture are at high risk of having another one. A fracture over the age of 50 or several fractures before that age may be a warning sign that a person has already developed osteoporosis. Any fracture in an older person should be followed up for suspicion of osteoporosis.
Congenital fiber-type disproportion is thought to be a rare condition, although its prevalence is unknown.
Mutations in the SLC6A8 gene cause X-linked creatine deficiency. The SLC6A8 gene provides instructions for making a protein that transports the compound creatine into cells. Creatine is needed for the body to store and use energy properly. SLC6A8 gene mutations impair the ability of the transporter protein to bring creatine into cells, resulting in a creatine shortage (deficiency). The effects of creatine deficiency are most severe in organs and tissues that require large amounts of energy, especially the brain.
The signs and symptoms of astrocytomas are not the same in every child. Signs and symptoms depend on the following: - Where the tumor forms in the brain or spinal cord. - The size of the tumor. - How fast the tumor grows. - The child's age and development. Some tumors do not cause signs or symptoms. Signs and symptoms may be caused by childhood astrocytomas or by other conditions. Check with your child's doctor if your child has any of the following: - Morning headache or headache that goes away after vomiting. - Nausea and vomiting. - Vision, hearing, and speech problems. - Loss of balance and trouble walking. - Worsening handwriting or slow speech. - Weakness or change in feeling on one side of the body. - Unusual sleepiness. - More or less energy than usual. - Change in personality or behavior. - Seizures. - Weight loss or weight gain for no known reason. - Increase in the size of the head (in infants).

Pompe disease affects about 1 in 40,000 people in the United States. The incidence of this disorder varies among different ethnic groups.
Congenital varicella syndrome is an extremely rare disorder in which affected infants have distinctive abnormalities at birth due to the mother's infection with chickenpox (maternal varicella zoster) early during pregnancy (i.e., up to 20 weeks gestation). Affected newborns may have a low birth weight and characteristic abnormalities of the skin, brain, eyes, the arms, legs, hands, and/or feet, and/or, in rare cases, other areas of the body. The range and severity of associated symptoms and physical findings may vary greatly from case to case depending upon when maternal varicella zoster infection occurred during fetal development.
GM2-gangliosidosis, AB variant is a rare inherited disorder that progressively destroys nerve cells (neurons) in the brain and spinal cord. Signs and symptoms of the AB variant become apparent in infancy. Infants with this disorder typically appear normal until the age of 3 to 6 months, when their development slows and muscles used for movement weaken. Affected infants lose motor skills such as turning over, sitting, and crawling. They also develop an exaggerated startle reaction to loud noises. As the disease progresses, children with the AB variant experience seizures, vision and hearing loss, intellectual disability, and paralysis. An eye abnormality called a cherry-red spot, which can be identified with an eye examination, is characteristic of this disorder. Children with the AB variant usually live only into early childhood.
Persistent genital arousal disorder (PGAD) in men may be considered as the condition of priapism and unwanted ejaculatory fluids being released without any sexual interest. In women there is still no consensus about a formal definition, but some of the experts propose that in women it should be defined as a rare, unwanted, and intrusive sexual dysfunction associated with excessive and unremitting genital arousal and engorgement in the absence of sexual interest. The persistent genital arousal usually does not resolve with orgasm and causes personal distress. Features include excessive excitement or excessive genital (lubrication, swelling, and engorgement) or other somatic responses. Causes may be neurological (central or peripheral involving the pudendal nerve), related to medication, vascular, hormonal, psychological or others. Diagnosis of the cause is essential for an adequate patient management. The treatment may include avoiding offending medications, using medications that stabilize nerve transmission and/or effect mood, local topical anesthetic agents, ice and hormonal replacement. More recently PGAD has being described as one component of a broader Restless Genital Syndrome if the PGAD was also associated with urinary frequency/urgency and restless leg syndrome.
Kawasaki disease can't be prevented. However, most children who have the disease recoverusually within weeks of getting signs and symptoms. Further problems are rare.
SHORT syndrome has an autosomal dominant pattern of inheritance, which means one copy of the altered PIK3R1 gene in each cell is sufficient to cause the disorder. In most cases, the condition results from a new mutation in the gene and occurs in people with no history of the disorder in their family. In other cases, an affected person inherits the mutation from one affected parent.
Pretibial epidermolysis bullosa is a rare form of epidermolysis bullosa, a condition characterized by fragile skin that blisters easily in response to minor injury or friction. In the pretibial form, specifically, the characteristic blisters and skin erosions develop predominantly on the front of the lower legs (known as the "pretibial region"). In some affected people, the feet, hands and/or nails may also be affected. Healing of the blisters is generally associated with hypertrophic scarring. Pretibial epidermolysis bullosa is caused by changes (mutations) in the COL7A1 gene and can be inherited in an autosomal dominant or autosomal recessive manner. Treatment is based on the signs and symptoms present in each person.
Even if the surgeon removes all of the cancer that can be seen at the time of surgery, a woman may still receive follow-up treatment. This may include radiation therapy, chemotherapy, or hormone therapy to try to kill any cancer cells that may be left. Treatment that a patient receives after surgery to increase the chances of a cure is called adjuvant therapy.
The National Institute of Neurological Disorders and Stroke (NINDS) and other institutes at the National Institutes of Health conduct research related to dysphagia in their clinics and laboratories and support additional research through grants to major medical institutions across the country. Much of this research focuses on finding better ways to treat dysphagia.
Certain factors affect prognosis (chance of recovery) and treatment options. The prognosis (chance of recovery) and treatment options depend on the following: - The stage of the cancer (the size of the tumor, whether it affects part or all of the liver, or has spread to other places in the body). - How well the liver is working. - The patients general health, including whether there is cirrhosis of the liver.
Treatment is not needed for simple kidney cysts that do not cause any symptoms. Simple kidney cysts may be monitored with periodic ultrasounds. Simple kidney cysts that are causing symptoms or blocking the flow of blood or urine through the kidney may need to be treated using a procedure called sclerotherapy. In sclerotherapy, the doctor punctures the cyst using a long needle inserted through the skin. Ultrasound is used to guide the needle to the cyst. The cyst is drained and then filled with a solution containing alcohol to make the kidney tissue harder. The procedure is usually performed on an outpatient basis with a local anesthetic. If the cyst is large, surgery may be needed. Most surgeries can be performed using a laparoscopea special tool with a small, lighted video camera. The procedure is usually done under general anesthesia in a hospital. The surgeon drains the cyst and then removes or burns away its outer tissue. This type of surgery allows for a smaller incision and quicker recovery.
Unlike previous surgeries for PD, DBS involves minimal permanent surgical changes to the brain. Instead, the procedure uses electrical stimulation to regulate electrical signals in neural circuits to and from identified areas in the brain to improve PD symptoms. Thus, if DBS causes unwanted side effects or newer, more promising treatments develop in the future, the implantable pulse generator can be removed, and the DBS procedure can be halted. Also, stimulation from the IPG is easily adjustablewithout further surgeryif the persons condition changes. Some people describe the pulse generator adjustments as "programming."
X-linked adrenal hypoplasia congenita is an inherited disorder that mainly affects males. It involves many hormone-producing (endocrine) tissues in the body, particularly a pair of small glands on top of each kidney called the adrenal glands. These glands produce a variety of hormones that regulate many essential functions in the body. Congenital adrenal hypoplasia is characterized by adrenal insufficiency, which may be life threatening, and hypogonadotropic hypogonadism. Congenital adrenal hypoplasia is caused by mutations in the NR0B1 gene. It is inherited in an X-linked recessive pattern.

Summary : Cancer is common. Half of all men and a third of women will get a diagnosis of cancer in their lifetime. Many people with cancer do survive. Millions of Americans alive today have a history of cancer. For most people with cancer, living with the disease is the biggest challenge they have ever faced. It can change your routines, roles and relationships. It can cause money and work problems. The treatment can change the way you feel and look. Learning more about ways you can help yourself may ease some of your concerns. Support from others is important. All cancer survivors should have follow-up care. Knowing what to expect after cancer treatment can help you and your family make plans, lifestyle changes, and important decisions. NIH: National Cancer Institute
Depression is more than just feeling blue or sad. It is an illness. When you have depression, it interferes with daily life and normal functioning, and causes pain for both you and those who care about you.
