This condition is inherited in an autosomal dominant pattern, which means one altered or missing copy of the GLI3 gene in each cell is sufficient to cause the disorder. In some cases, an affected person inherits a gene mutation or chromosomal abnormality from one affected parent. Other cases occur in people with no history of the condition in their family.

How is von Hippel-Lindau (VHL) disease diagnosed? The diagnosis of von Hippel-Lindau (VHL) disease can be made based on specific clinical criteria (signs and symptoms), or when molecular genetic testing reveals a mutation in the VHL gene. Tests that may be used to establish a clinical diagnosis include: MRI of the brain and spinal cord fundoscopy ultrasound examination or MRI of the abdomen blood and urinary catecholamine metabolites.

For people who are on dialysis or approaching total kidney failure, adequate nutrition is important for maintaining energy, strength, healthy sleep patterns, bone health, heart health, and good mental health. A persons treatment will dictate the type of diet that should be followed:
- People on hemodialysis must watch how much fluid they drink and avoid eating foods with too much sodium, potassium, and phosphorus. - In contrast, people on peritoneal dialysisa type of dialysis that uses the lining of the abdomen, or belly, to filter the blood inside the bodymay be able to eat more potassium-rich foods because peritoneal dialysis removes potassium from the body more efficiently than hemodialysis. - Both hemodialysis and peritoneal dialysis can remove proteins from the body, so anyone on either form of dialysis should eat protein-rich foods such as meat, fish, and eggs.
All dialysis centers and transplant clinics have a renal dietitian who specializes in helping people with kidney failure. People who are on dialysis or have a kidney transplant should talk with their clinics renal dietitian to develop a meal plan that will enhance the effectiveness of their treatment.
For more information about nutrition for people with advanced CKD or who are on dialysis, see NIDDK health topics, Nutrition for Advanced Chronic Kidney Disease in Adults or Kidney Failure: Eat Right to Feel Right on Hemodialysis.

Dentinogenesis imperfecta is a disorder of tooth development. This condition causes the teeth to be discolored (most often a blue-gray or yellow-brown color) and translucent. Teeth are also weaker than normal, making them prone to rapid wear, breakage, and loss. These problems can affect both primary (baby) teeth and permanent teeth. Researchers have described three types of dentinogenesis imperfecta with similar dental abnormalities. Type I occurs in people who have osteogenesis imperfecta, a genetic condition in which bones are brittle and easily broken. Dentinogenesis imperfecta type II and type III usually occur in people without other inherited disorders. A few older individuals with type II have had progressive high-frequency hearing loss in addition to dental abnormalities, but it is not known whether this hearing loss is related to dentinogenesis imperfecta. Some researchers believe that dentinogenesis imperfecta type II and type III, along with a condition called dentin dysplasia type II, are actually forms of a single disorder. The signs and symptoms of dentin dysplasia type II are very similar to those of dentinogenesis imperfecta. However, dentin dysplasia type II affects the primary teeth much more than the permanent teeth.

Stuve-Wiedemann syndrome (STWS) is a congenital bone dysplasia characterized by small stature, congenital bowing of the long bones and other skeletal anomalies. Patients present with serious complications including respiratory and feeding distress and recurrent episodes of unexplained hyperthermia (elevated body temperature). The condition is transmitted in an autosomal recessive fashion and appears to be caused by mutations in the leukemia inhibitory factor receptor gene (LIFR) on chromosome 5p13. The majority of patients die during the neonatal period. The rare survivors develop progressive scoliosis, spontaneous fractures, bowing of the lower limbs, with prominent joints and dysautonomia symptoms, including temperature instability, absent corneal and patellar reflexes, and smooth tongue. Treatment is symptomatic and supportive.

Ataxia telangiectasia (A-T) is rare condition that affects the nervous system, the immune system, and many other parts of the body. Signs and symptoms of the condition usually begin in early childhood, often before age 5. The condition is typically characterized by cerebellar ataxia (uncoordinated muscle movements), oculomotor apraxia, telangiectasias, choreoathetosis (uncontrollable movements of the limbs), a weakened immune system with frequent infections, and an increased risk of cancers such as leukemia and lymphoma. A-T is caused by changes (mutations) in the ATM gene and is inherited in an autosomal recessive manner. Treatment is supportive and based on the signs and symptoms present in each person.

Gray platelet syndrome can be caused by mutations in the NBEAL2 gene. Little is known about the protein produced from this gene. It appears to play a role in the formation of alpha-granules, which are sacs inside platelets that contain growth factors and other proteins that are important for blood clotting and wound healing. In response to an injury that causes bleeding, the proteins stored in alpha-granules help platelets stick to one another to form a plug that seals off damaged blood vessels and prevents further blood loss. Mutations in the NBEAL2 gene disrupt the normal production of alpha-granules. Without alpha-granules, platelets are unusually large and fewer in number than usual (macrothrombocytopenia). The abnormal platelets also appear gray when viewed under a microscope, which gives this condition its name. A lack of alpha-granules impairs the normal activity of platelets during blood clotting, increasing the risk of abnormal bleeding. Myelofibrosis is thought to occur because the growth factors and other proteins that are normally packaged into alpha-granules leak out into the bone marrow. The proteins lead to fibrosis that affects the bone marrow's ability to make new blood cells. Some people with gray platelet syndrome do not have an identified mutation in the NBEAL2 gene. In these individuals, the cause of the condition is unknown.

What causes lichen sclerosus? The underlying cause of lichen sclerosus is not fully understood. The condition may be due to genetic, hormonal, irritant and/or infectious factors (or a combination of these factors). It is believed to relate to an autoimmune process, in which antibodies mistakenly attack a component of the skin. Other autoimmune conditions are reported to occur more frequently than expected in people with lichen sclerosis. In some cases, lichen sclerosus appears on skin that has been damaged or scarred from previous injury or trauma.

There are no specific treatments to prevent or slow the progressive degeneration seen in Troyer syndrome. Symptomatic therapy includes antispasmodic drugs and physical therapy to improve muscle strength and maintain range of motion in the legs. Assistive devices may be needed to help with walking.
|
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.

The stomach is an organ between the esophagus and the small intestine. It mixes food with stomach acid and helps digest protein. Stomach cancer mostly affects older people - two-thirds of people who have it are over age 65. Your risk of getting it is also higher if you - Have had a Helicobacter pylori infection - Have had stomach inflammation - Are a man - Eat lots of salted, smoked, or pickled foods - Smoke cigarettes - Have a family history of stomach cancer It is hard to diagnose stomach cancer in its early stages. Indigestion and stomach discomfort can be symptoms of early cancer, but other problems can cause the same symptoms. In advanced cases, there may be blood in your stool, vomiting, unexplained weight loss, jaundice, or trouble swallowing. Doctors diagnose stomach cancer with a physical exam, blood and imaging tests, an endoscopy, and a biopsy. Because it is often found late, it can be hard to treat stomach cancer. Treatment options include surgery, chemotherapy, radiation or a combination. NIH: National Cancer Institute

Researchers have not found that eating, diet, and nutrition play a role in causing or preventing primary amyloidosis of the kidneys or dialysis-related amyloidosis. People with nephrotic syndrome may make dietary changes such as
- limiting dietary sodium, often from salt, to help reduce edema and lower blood pressure - decreasing liquid intake to help reduce edema and lower blood pressure - eating a diet low in saturated fat and cholesterol to help control more-than-normal amounts of fats and cholesterol in the blood
Health care providers may recommend that people with kidney disease eat moderate or reduced amounts of protein. Proteins break down into waste products that the kidneys filter from the blood. Eating more protein than the body needs may burden the kidneys and cause kidney function to decline faster. However, protein intake that is too low may lead to malnutrition, a condition that occurs when the body does not get enough nutrients.
People with kidney disease on a restricted protein diet should receive blood tests that can show low nutrient levels. People with primary amyloidosis of the kidneys or dialysis-related amyloidosis should talk with a health care provider about dietary restrictions to best manage their individual needs.

Fabry disease is an inherited disorder that results from the buildup of a particular type of fat in the body's cells, called globotriaosylceramide or GL-3. Fabry disease affects many parts of the body. Signs and symptoms may include episodes of pain, particularly in the hands and feet (acroparesthesias); clusters of small, dark red spots on the skin called angiokeratomas; a decreased ability to sweat (hypohidrosis); cloudiness of the front part of the eye (corneal opacity); and hearing loss. Potentially severe complications can include progressive kidney damage, heart attack, and stroke. Milder forms of the disorder may appear later in life and affect only the heart or kidneys. Fabry disease is caused by mutations in the GLA gene and is inherited in an X-linked manner. Treatment may include enzyme replacement therapy (ERT); pain medications, ACE inhibitors; and chronic hemodialysis or renal transplantation for end stage renal disease.

Pityriasis rubra pilaris (PRP) refers to a group of skin conditions that cause constant inflammation and scaling of the skin. Affected people have reddish-orange colored patches; they may occur everywhere on the body or only on certain areas. There are several types of PRP, which are classified based on age of onset, body areas affected, and whether other associated conditions are present. PRP is usually sporadic (occurring randomly) but some forms may be inherited.

Menkes disease is caused by a defective gene named ATPTA1 that regulates the metabolism of copper in the body. The disease primarily affects male infants. Copper accumulates at abnormally low levels in the liver and brain, but at higher than normal levels in the kidney and intestinal lining. Affected infants may be born prematurely, but appear healthy at birth and develop normally for 6 to 8 weeks. Then symptoms begin, including floppy muscle tone, seizures, and failure to thrive. Menkes disease is also characterized by subnormal body temperature and strikingly peculiar hair, which is kinky, colorless or steel-colored, and breaks easily. There is often extensive neurodegeneration in the gray matter of the brain. Arteries in the brain may be twisted with frayed and split inner walls. This can lead to rupture or blockage of the arteries. Weakened bones (osteoporosis) may result in fractures.
|
Cole disease is a disorder that affects the skin. People with this disorder have areas of unusually light-colored skin (hypopigmentation), typically on the arms and legs, and spots of thickened skin on the palms of the hands and the soles of the feet (punctate palmoplantar keratoderma). These skin features are present at birth or develop in the first year of life. In some cases, individuals with Cole disease develop abnormal accumulations of the mineral calcium (calcifications) in the tendons, which can cause pain during movement. Calcifications may also occur in the skin or breast tissue.

Mitochondrial myopathies are a group of neuromuscular diseases caused by damage to the mitochondriasmall, energy-producing structures that serve as the cells' "power plants." Nerve cells in the brain and muscles require a great deal of energy, and thus appear to be particularly damaged when mitochondrial dysfunction occurs. Some of the more common mitochondrial myopathies include Kearns-Sayre syndrome, myoclonus epilepsy with ragged-red fibers, and mitochondrial encephalomyopathy with lactic acidosis and stroke-like episodes. The symptoms of mitochondrial myopathies include muscle weakness or exercise intolerance, heart failure or rhythm disturbances, dementia, movement disorders, stroke-like episodes, deafness, blindness, droopy eyelids, limited mobility of the eyes, vomiting, and seizures. The prognosis for these disorders ranges in severity from progressive weakness to death. Most mitochondrial myopathies occur before the age of 20, and often begin with exercise intolerance or muscle weakness. During physical activity, muscles may become easily fatigued or weak. Muscle cramping is rare, but may occur. Nausea, headache, and breathlessness are also associated with these disorders.

What are the signs and symptoms of cerebellar degeneration? Cerebellar degeneration is primarily characterized by a wide-legged, unsteady, lurching walk that is usually accompanied by a back and forth tremor in the trunk of the body. Other signs and symptoms may include slow, unsteady and jerky movement of the arms or legs; slowed and slurred speech; and nystagmus. Although cerebellar disorders usually strike adults in middle age, the age of symptomatic onset varies depending on the underlying cause of the degeneration. Studies have shown that many patients with movement disorders caused by damage to the cerebellum also have psychiatric symptoms. These studies suggest that patients with cerebellar diseases may benefit from screening and treatment of psychiatric disorders.

How might Juvenile Huntington disease (HD) be treated? Physicians may prescribe a number of medications to help control emotional and movement problems associated with HD. It is important to remember however, that while medicines may help keep these clinical symptoms under control, there is no treatment to stop or reverse the course of the disease. Anticonvulsant drugs are usually prescribed to help prevent and control the seizures that occur in children with Juvenile HD. Tetrabenazine is often used to treat chorea. Antipsychotic drugs, such as haloperidol, or other drugs, such as clonazepam, may also help to alleviate chorea and may also be used to help control hallucinations, delusions, and violent outbursts. For depression, physicians may prescribe fluoxetine, sertraline, nortriptyline, or other drugs. Tranquilizers can help control anxiety and lithium may be prescribed to combat severe mood swings.

Membranous nephropathy is a kidney disease characterized by inflammation of the structures inside the kidney that help filter wastes and fluids. When the glomerular basement membrane becomes thickened, it does not work normally, allowing large amounts of protein to be lost in the urine. Symptoms develop gradually and may include swelling, fatigue, weight gain, and high blood pressure. In many cases, the underlying cause of membranous nephropathy is not known. Some cases are associated with other conditions (lupus), infections (hepatitis B and C), cancer or as a side effect of certain medications. The goal of treatment is to reduce symptoms and slow the progression of the disease.

A hearing aid is a small electronic device that you wear in or behind your ear. It makes some sounds louder. A hearing aid can help people hear more in both quiet and noisy situations. Hearing aids help people who have hearing loss from damage to the small sensory cells in the inner ear. The damage can occur as a result of disease, aging, or injury from noise or certain medicines. Only about one out of five people who would benefit from a hearing aid actually uses one. If you think a hearing aid could help you, visit your doctor. There are different kinds of hearing aids. They differ by size, their placement on or inside the ear, and how much they amplify sound. The hearing aid that will work best for you depends on what kind of hearing loss you have, and how severe it is. NIH: National Institute on Deafness and Other Communication Disorders

Mutations in the COL11A2 gene cause Weissenbacher-Zweymller syndrome. The COL11A2 gene is one of several genes that provide instructions for the production of type XI collagen. This type of collagen is important for the normal development of bones and other connective tissues that form the body's supportive framework. At least one mutation in the COL11A2 gene is known to cause Weissenbacher-Zweymller syndrome. This mutation disrupts the assembly of type XI collagen molecules, resulting in delayed bone development and the other features of this disorder.

In some cases, a health care provider will order genetic blood tests to confirm or rule out a diagnosis of celiac disease. Most people with celiac disease have gene pairs that contain at least one of the human leukocyte antigen (HLA) gene variants.4 However, these variants are also common in people without celiac disease, so their presence alone cannot diagnose celiac disease.
If a biopsy and other blood tests do not give a clear diagnosis of celiac disease, a health care provider may test a patient for HLA gene variants. If the gene variants are not present, celiac disease is unlikely.

Juvenile Huntington disease (HD) is a less common, early-onset form of Huntington disease that begins in childhood or adolescence. It is also a progressive disorder that causes the breakdown of brain cells in certain areas of the brain. This results in uncontrolled movements, loss of intellectual abilities, and emotional disturbances. Juvenile HD is defined by the onset of symptoms before age 20 years and accounts for 5-10% of HD cases. It is inherited in an autosomal dominant pattern and is caused by a mutation called a trinucleotide repeat in the HTT gene. Most often, children with juvenile HD inherit the mutation repeat from their fathers, although on occasion they inherit it from their mothers. Juvenile Huntington disease has a rapid disease progression once symptoms present. There currently is no cure. Treatment is supportive and focused on increasing quality of life.

Mutations in the CPT2 gene cause CPT II deficiency. This gene provides instructions for making an enzyme called carnitine palmitoyltransferase 2. This enzyme is essential for fatty acid oxidation, which is the multistep process that breaks down (metabolizes) fats and converts them into energy. Fatty acid oxidation takes place within mitochondria, which are the energy-producing centers in cells. A group of fats called long-chain fatty acids must be attached to a substance known as carnitine to enter mitochondria. Once these fatty acids are inside mitochondria, carnitine palmitoyltransferase 2 removes the carnitine and prepares them for fatty acid oxidation. Fatty acids are a major source of energy for the heart and muscles. During periods of fasting, fatty acids are also an important energy source for the liver and other tissues. Mutations in the CPT2 gene reduce the activity of carnitine palmitoyltransferase 2. Without enough of this enzyme, carnitine is not removed from long-chain fatty acids. As a result, these fatty acids cannot be metabolized to produce energy. Reduced energy production can lead to some of the features of CPT II deficiency, such as hypoketotic hypoglycemia, myalgia, and weakness. Fatty acids and long-chain acylcarnitines (fatty acids still attached to carnitine) may also build up in cells and damage the liver, heart, and muscles. This abnormal buildup causes the other signs and symptoms of the disorder.

Certain factors affect prognosis (chance of recovery) and treatment options. The prognosis (chance of recovery) and treatment options depend on the following: - Where the tumor is in the gastrointestinal tract. - The size of the tumor. - Whether the cancer has spread from the stomach and intestines to other parts of the body, such as the liver or lymph nodes. - Whether the patient has carcinoid syndrome or has carcinoid heart syndrome. - Whether the cancer can be completely removed by surgery. - Whether the cancer is newly diagnosed or has recurred.

Sinusitis means your sinuses are inflamed. The cause can be an infection or another problem. Your sinuses are hollow air spaces within the bones surrounding the nose. They produce mucus, which drains into the nose. If your nose is swollen, this can block the sinuses and cause pain. There are several types of sinusitis, including - Acute, which lasts up to 4 weeks - Subacute, which lasts 4 to 12 weeks - Chronic, which lasts more than 12 weeks and can continue for months or even years - Recurrent, with several attacks within a year Acute sinusitis often starts as a cold, which then turns into a bacterial infection. Allergies, nasal problems, and certain diseases can also cause acute and chronic sinusitis. Symptoms of sinusitis can include fever, weakness, fatigue, cough, and congestion. There may also be mucus drainage in the back of the throat, called postnasal drip. Your health care professional diagnoses sinusitis based on your symptoms and an examination of your nose and face. You may also need imaging tests. Treatments include antibiotics, decongestants, and pain relievers. Using heat pads on the inflamed area, saline nasal sprays, and vaporizers can also help.

Acrodermatitis enteropathica (AE) is a disorder of zinc metabolism that can either be inherited or acquired. Both forms lead to the inability to absorb zinc from the intestine. The lack of zinc can cause skin inflammation with a rash (pustular dermatitis) around the mouth and/or anus; diarrhea; and abnormal nails (nail dystrophy). Irritability and emotional disturbances can also occur. The inherited form is caused by mutations in the SLC39A4 gene and inherited in an autosomal recessive pattern. The acquired form can result from diets lacking the appropriate amount of zinc. Supplemental zinc usually eliminates the symptoms of acrodermatitis enteropathica.

Todd's paralysis is a neurological condition experienced by individuals with epilepsy, in which a seizure is followed by a brief period of temporary paralysis. The paralysis may be partial or complete but usually occurs on just one side of the body. The paralysis can last from half an hour to 36 hours, with an average of 15 hours, at which point it resolves completely. Todd's paralysis may also affect speech and vision. Scientists don't know what causes Todd's paralysis. Current theories propose biological processes in the brain that involve a slow down in either the energy output of neurons or in the motor centers of the brain. It is important to distinguish Todd's paralysis from a stroke, which it can resemble, because a stroke requires completely different treatment.

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 (level of PSA, Gleason score, grade of the tumor, how much of the prostate is affected by the cancer, and whether the cancer has spread to other places in the body). - The patients age. - Whether the cancer has just been diagnosed or has recurred (come back). Treatment options also may depend on the following: - Whether the patient has other health problems. - The expected side effects of treatment. - Past treatment for prostate cancer. - The wishes of the patient. Most men diagnosed with prostate cancer do not die of it.

Glycogen storage disease type 1B (GSD1B) is an inherited condition in which the body is unable to break down a complex sugar called glycogen. As a result, glycogen accumulates in cells throughout the body. In GSD1B, specifically, glycogen and fats build up within the liver and kidneys which can cause these organs to be enlarged and not function properly. Signs and symptoms of the condition generally develop at age 3 to 4 months and may include hypoglycemia, seizures, lactic acidosis, hyperuricemia (high levels of a waste product called uric acid in the body), and hyperlipidemia. Affected people may also have short stature; thin arms and legs; a protruding abdomen; neutropenia (which may lead to frequent infections); inflammatory bowel disease and oral health problems. GSD1B is caused by changes (mutations) in the SLC37A4 gene and is inherited in an autosomal recessive manner. Although there is currently no cure for the condition, symptoms can often be managed with a special diet in combination with certain medications.
|
Duchenne muscular dystrophy (DMD) is a rapidly progressive form of muscular dystrophy that occurs primarily in boys. It is caused by a mutation in a gene, called the DMD gene, which encodes the muscle protein dystrophin. Boys with Duchenne muscular dystrophy do not make the dystrophin protein in their muscles. Duchenne mucular dystrophy is inherited in an X-linked recessive fashion; however, it may also occur in people from families without a known family history of the condition. Individuals who have DMD have progressive loss of muscle function and weakness, which begins in the lower limbs. In addition to the skeletal muscles used for movement, DMD may also affect the muscles of the heart. There is no known cure for Duchenne muscular dystrophy. Treatment is aimed at control of symptoms to maximize the quality of life.

Currently, no medication can cure Alzheimers disease, but four medicines are approved to treat the symptoms of the disease. - Aricept (donezepil)for all stages of Alzheimers - Exelon (rivastigmine)for mild to moderate Alzheimers - Razadyne (galantamine)--for mild to moderate Alzheimers - Namenda (memantine)for moderate to severe Alzheimers - Namzarec (memantine and donepezil)for moderate to severe Alzheimers Aricept (donezepil)for all stages of Alzheimers Exelon (rivastigmine)for mild to moderate Alzheimers Razadyne (galantamine)--for mild to moderate Alzheimers Namenda (memantine)for moderate to severe Alzheimers Namzarec (memantine and donepezil)for moderate to severe Alzheimers These medications can help slow down memory loss and allow people with Alzheimers to be more comfortable and independent for a longer time. If appropriate, the persons doctor may prescribe a medicine to treat behavior problems such as anxiety, depression, and aggression. Medicines to treat these behavior problems should be used only after other strategies have been tried. Talk with the doctor about which medicines are safest and most effective.
|
Treatment for CIDP includes corticosteroids such as prednisone, which may be prescribed alone or in combination with immunosuppressant drugs. Plasmapheresis (plasma exchange) and intravenous immunoglobulin (IVIg) therapy are effective. IVIg may be used even as a first-line therapy. Physiotherapy may improve muscle strength, function and mobility, and minimize the shrinkage of muscles and tendons and distortions of the joints.

What are the signs and symptoms of Jensen syndrome? The Human Phenotype Ontology provides the following list of signs and symptoms for Jensen 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) Blindness - Cerebral calcification - Dementia - Generalized amyotrophy - Infantile sensorineural hearing impairment - Optic atrophy - X-linked inheritance - 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.

Myotonic dystrophy type 1 is caused by mutations in the DMPK gene, while type 2 results from mutations in the CNBP gene. The specific functions of these genes are unclear. The protein produced from the DMPK gene may play a role in communication within cells. It appears to be important for the correct functioning of cells in the heart, brain, and skeletal muscles (which are used for movement). The protein produced from the CNBP gene is found primarily in the heart and in skeletal muscles, where it probably helps regulate the function of other genes. Similar changes in the structure of the DMPK and CNBP genes cause the two forms of myotonic dystrophy. In each case, a segment of DNA is abnormally repeated many times, forming an unstable region in the gene. The mutated gene produces an expanded version of messenger RNA, which is a molecular blueprint of the gene that is normally used to guide the production of proteins. The abnormally long messenger RNA forms clumps inside the cell that interfere with the production of many other proteins. These changes prevent muscle cells and cells in other tissues from functioning normally, which leads to the signs and symptoms of myotonic dystrophy.

The bladder is a hollow organ in your lower abdomen that stores urine. Bladder cancer occurs in the lining of the bladder. It is the sixth most common type of cancer in the United States. Symptoms include - Blood in your urine - A frequent urge to urinate - Pain when you urinate - Low back pain Risk factors for developing bladder cancer include smoking and exposure to certain chemicals in the workplace. People with a family history of bladder cancer or who are older, white, or male have a higher risk. Treatments for bladder cancer include surgery, radiation therapy, chemotherapy, and biologic therapy. Biologic therapy boosts your body's own ability to fight cancer. NIH: National Cancer Institute

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.
|
Some cases of PRICKLE1-related progressive myoclonus epilepsy with ataxia are 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. Other cases of PRICKLE1-related progressive myoclonus epilepsy with ataxia are considered autosomal dominant because one copy of the altered gene in each cell is sufficient to cause the disorder. These cases result from new mutations in the gene and occur in people with no history of the disorder in their family.
|
What causes thanatophoric dysplasia? Thanatophoric dysplasia is caused by mutations in the FGFR3 gene. This gene provides instructions for making a protein that is involved in the development and maintenance of bone and brain tissue. Mutations in this gene cause the FGFR3 protein to be overly active, which leads to the severe problems with bone growth that are seen in thanatophoric dysplasia. It is not known how FGFR3 mutations cause the brain and skin abnormalities associated with this disorder.

Original Medicare is managed by the Federal government and lets people with Medicare go to any doctor, hospital or other health care provider who accepts Medicare. It is a fee-for-service plan, meaning that the person with Medicare usually pays a fee for each service. Medicare pays its share of an approved amount up to certain limits, and the person with Medicare pays the rest. People in Original Medicare must choose and join a Medicare Prescription Drug Plan if they want to get Medicare prescription drug coverage. For more information about Original Medicare, visit http://www.medicare.gov for a free copy of "Your Medicare Benefits." (Under "Search Tools," select "Find a Medicare Publication.")

How might benign multicystic peritoneal mesothelioma be treated? Surgery to remove the cystic lesions is the only effective treatment for BMPM. Aggressive surgical approaches are often recommended. Hormonal therapy has also been attempted in individual cases with variable degrees of success. Most affected individuals do not undergo chemotherapy and/or radiotherapy because these tumors are usually benign.

Sjgren's syndrome can damage vital organs of the body with symptoms that may remain stable, worsen, or go into remission. Some people may experience only the mild symptoms of dry eyes and mouth, while others go through cycles of good health followed by severe disease. Many patients are able to treat problems symptomatically. Others are forced to cope with blurred vision, constant eye discomfort, recurrent mouth infections, swollen parotid glands, hoarseness, and difficulty in swallowing and eating. Debilitating fatigue and joint pain can seriously impair quality of life.

Liddle syndrome is caused by mutations in the SCNN1B or SCNN1G gene. Each of these genes provides instructions for making a piece (subunit) of a protein complex called the epithelial sodium channel (ENaC). These channels are found at the surface of certain cells called epithelial cells in many tissues of the body, including the kidneys, where the channels transport sodium into cells. In the kidney, ENaC channels open in response to signals that sodium levels in the blood are too low, which allows sodium to flow into cells. From the kidney cells, this sodium is returned to the bloodstream (a process called reabsorption) rather than being removed from the body in urine. Mutations in the SCNN1B or SCNN1G gene change the structure of the respective ENaC subunit. The changes alter a region of the subunit that is involved in signaling for its breakdown (degradation) when it is no longer needed. As a result of the mutations, the subunit proteins are not degraded, and more ENaC channels remain at the cell surface. The increase in channels at the cell surface abnormally increases the reabsorption of sodium (followed by water), which leads to hypertension. Reabsorption of sodium into the blood is linked with removal of potassium from the blood, so excess sodium reabsorption leads to hypokalemia.

Serpiginous choroiditis is a rare inflammatory eye condition that typically develops between age 30 and 70 years. Affected individuals have lesions in the eye that last from weeks to months and involve scarring of the eye tissue. Recurrence of these lesions is common in serpiginous choroiditis. Vision loss may occur in one or both eyes when the macula is involved. Treatment options involve anti-inflammatory and immune-suppressing medications.

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.

Good syndrome is a rare, adult-onset primary immunodeficiency suspected in patients who exhibit hypogammaglobulinemia and low levels of B cells along with a benign thymic tumor (thymoma) on chest X-ray. Symptoms include frequent opportunistic infections involving the sinuses and lungs, including severe CMV disease, P. carinii pneumonia, and mucocutaneous candidiasis. While the cause of Good syndrome remains unknown, there is some evidence that a defect of the bone marrow is involved. Treatment includes removal of the thymic tumor and immunoglobulin replacement.

People who have any signs or symptoms of severe dehydration should call or see a health care provider right away:
- excessive thirst - dark-colored urine - infrequent urination - lethargy, dizziness, or faintness - dry skin
Infants, children, older adults, and people with weak immune systems have the greatest chance of becoming dehydrated. People should watch for the following signs and symptoms of dehydration in infants, young children, and people who are unable to communicate their symptoms:
- dry mouth and tongue - lack of tears when crying - infants with no wet diapers for 3 hours or more - infants with a sunken soft spot - unusually cranky or drowsy behavior - sunken eyes or cheeks - fever
If left untreated, severe dehydration can cause serious health problems, such as organ damage, shock, or comaa sleeplike state in which a person is not conscious.

Congenital neuronal ceroid lipofuscinosis (NCL) is an inherited disorder that primarily affects the nervous system. Soon after birth, affected infants develop muscle rigidity, respiratory failure, and prolonged episodes of seizure activity that last several minutes (status epilepticus). It is likely that some affected individuals have seizure activity before birth. Infants with congenital NCL have unusually small heads (microcephaly) with brains that may be less than half the normal size. There is a loss of brain cells in areas that coordinate movement and control thinking and emotions (the cerebellum and the cerebral cortex). Affected individuals also lack a fatty substance called myelin, which protects nerve cells and promotes efficient transmission of nerve impulses. Infants with congenital NCL often die hours to weeks after birth. Congenital NCL is the most severe form of a group of NCLs (collectively called Batten disease) that affect the nervous system and typically cause progressive problems with vision, movement, and thinking ability. The different types of NCLs are distinguished by the age at which signs and symptoms first appear.

Special blood tests are used to diagnose polycythemia vera. In addition to a complete blood count, bone marrow aspiration and biopsy, and cytogenetic analysis, a serum erythropoietin test is used to diagnose polycythemia vera. In this test, a sample of blood is checked for the level of erythropoietin (a hormone that stimulates new red blood cells to be made). In polycythemia vera, the erythropoietin level would be lower than normal because the body does not need to make more red blood cells.

Mutations in the CHM gene cause choroideremia. The CHM gene provides instructions for producing the Rab escort protein-1 (REP-1). As an escort protein, REP-1 attaches to molecules called Rab proteins within the cell and directs them to the membranes of various cell compartments (organelles). Rab proteins are involved in the movement of proteins and organelles within cells (intracellular trafficking). Mutations in the CHM gene lead to an absence of REP-1 protein or the production of a REP-1 protein that cannot carry out its protein escort function. This lack of functional REP-1 prevents Rab proteins from reaching and attaching (binding) to the organelle membranes. Without the aid of Rab proteins in intracellular trafficking, cells die prematurely. The REP-1 protein is active (expressed) throughout the body, as is a similar protein, REP-2. Research suggests that when REP-1 is absent or nonfunctional, REP-2 can perform the protein escort duties of REP-1 in many of the body's tissues. Very little REP-2 protein is present in the retina, however, so it cannot compensate for the loss of REP-1 in this tissue. Loss of REP-1 function and subsequent misplacement of Rab proteins within the cells of the retina causes the progressive vision loss characteristic of choroideremia.

Cartilage is the tough but flexible tissue that covers the ends of your bones at a joint. It also gives shape and support to other parts of your body, such as your ears, nose and windpipe. Healthy cartilage helps you move by allowing your bones to glide over each other. It also protects bones by preventing them from rubbing against each other. Injured, inflamed, or damaged cartilage can cause symptoms such as pain and limited movement. It can also lead to joint damage and deformity. Causes of cartilage problems include - Tears and injuries, such as sports injuries - Genetic factors - Other disorders, such as some types of arthritis Osteoarthritis results from breakdown of cartilage.

Adermatoglyphia is the absence of ridges on the skin on the pads of the fingers and toes, as well as on the palms of the hands and soles of the feet. The patterns of these ridges (called dermatoglyphs) form whorls, arches, and loops that are the basis for each person's unique fingerprints. Because no two people have the same patterns, fingerprints have long been used as a way to identify individuals. However, people with adermatoglyphia do not have these ridges, and so they cannot be identified by their fingerprints. Adermatoglyphia has been called the "immigration delay disease" because affected individuals have had difficulty entering countries that require fingerprinting for identification. In some families, adermatoglyphia occurs without any related signs and symptoms. In others, a lack of dermatoglyphs is associated with other features, typically affecting the skin. These can include small white bumps called milia on the face, blistering of the skin in areas exposed to heat or friction, and a reduced number of sweat glands on the hands and feet. Adermatoglyphia is also a feature of several rare syndromes classified as ectodermal dysplasias, including a condition called Naegeli-Franceschetti-Jadassohn syndrome/dermatopathia pigmentosa reticularis that affects the skin, hair, sweat glands, and teeth.

Certain factors affect prognosis (chance of recovery) and treatment options for primary myelofibrosis. Prognosis (chance of recovery) depends on the following: - The age of the patient. - The number of abnormal red blood cells and white blood cells. - The number of blasts in the blood. - Whether there are certain changes in the chromosomes. - Whether the patient has signs such as fever, night sweats, or weight loss.

Glucose-galactose malabsorption is a condition in which the cells lining the intestine cannot take in the sugars glucose and galactose, which prevents proper digestion of these molecules and larger molecules made from them. Glucose and galactose are called simple sugars, or monosaccharides. Sucrose (table sugar) and lactose (the sugar found in milk) are called disaccharides because they are made from two simple sugars, and are broken down into these simple sugars during digestion. Sucrose is broken down into glucose and another simple sugar called fructose, and lactose is broken down into glucose and galactose. As a result, lactose, sucrose and other compounds made from sugar molecules (carbohydrates) cannot be digested by individuals with glucose-galactose malabsorption. Glucose-galactose malabsorption generally becomes apparent in the first few weeks of a baby's life. Affected infants experience severe diarrhea resulting in life-threatening dehydration, increased acidity of the blood and tissues (acidosis), and weight loss when fed breast milk or regular infant formulas. However, they are able to digest fructose-based formulas that do not contain glucose or galactose. Some affected children are better able to tolerate glucose and galactose as they get older. Small amounts of glucose in the urine (mild glucosuria) may occur intermittently in this disorder. Affected individuals may also develop kidney stones or more widespread deposits of calcium within the kidneys.

Oral leukoplakia is a diagnosis of exclusion. It describes a white plaque that does not rub off and cannot be characterized as any other condition. Though it may occur in any part of the mouth, it generally affects the tongue, gums, and inner cheek. Physicians will usually biopsy oral leukoplakia lesions as 20-40% of cases are precancerous or cancerous at the time of biopsy and another 8-15% become cancerous over time. The exact cause of oral leukoplakia is not known. Factors that may increase the risk of developing oral leukoplakia include smoking, alcohol use, vitamin deficiencies, malocclusion, and a weakened immune system.Treatment depends on the biopsy results and the size, appearance, and location of the oral leukoplakia. Removal or ablation of the lesion by surgery, laser, or cryotherapy (use of low temperature) may be recommended.

Hereditary multiple osteochondromas (HMO) (formerly called hereditary multiple exostoses) is a genetic condition in which people develop multiple benign (noncancerous) bone tumors that are covered by cartilage (called osteochondromas). The number and location of osteochondromas varies greatly among affected individuals. These tumors are not present at birth, but almost all affected people develop multiple osteochondromas by the time they are 12 years old. Once the bones stop growing, the development of new osteochondromas also usually stops. Osteochondromas can cause abnormal growth of the arms, hands, and legs, which can lead to uneven limb lengths (limb length discrepancy) and short stature. These tumors may cause pain, limit joint movement, and exert pressure on nerves, blood vessels, and surrounding tissues. Osteochondromas are typically benign; however, researchers estimate that people with HMO have about a 1% lifetime risk of these tumors becoming a cancerous osteochondrosarcoma. HMO is caused by mutations in the EXT1 and EXT2 genes and is inherited in an autosomal dominant pattern.

Nuclear gene-encoded Leigh syndrome is a progressive neurological disease. It usually first becomes apparent in infancy with developmental delay or regression. Rarely, the disease begins in adolescence or adulthood. Symptoms progress to include generalized weakness, lack of muscle tone, spasticity, movement disorders, cerebellar ataxia, and peripheral neuropathy. Other signs and symptoms may include an increase in the heart muscle size (hypertrophic cardiomyopathy); excessive body hair (hypertrichosis); anemia; kidney or liver problems; and lung or heart failure. Nuclear gene-encoded Leigh syndrome (and Leigh-like syndrome, a term used for cases with similar features but that do not fulfill the diagnostic criteria for Leigh syndrome) may be caused by mutations in any of several genes and can be inherited in an autosomal recessive or X-linked manner. While treatment for some cases of Leigh-like syndrome may be available, management is generally supportive and focuses on the symptoms present.

There is no treatment that can cure or control CJD, although studies of a variety of drugs are now in progress. Current treatment is aimed at alleviating symptoms and making the person as comfortable as possible. Opiate drugs can help relieve pain, and the drugs clonazepam and sodium valproate may help relieve involuntary muscle jerks.Intravenous fluids and artificial feeding may be needed in later stages of the disease.

How might hyperprolinemia type 2 be treated? There is no specific treatment for hyperprolinemia type 2, even for those individuals who experience seizures. In general, if people with hyperprolinemia type 2 have symptoms, they are usually mild and do not require treatment. If seizures are present during childhood, they tend to disappear in adulthood. Attempts to reduce the amount of proline in an affected person's diet have resulted in only modest control of proline levels in the blood and have not reduced symptoms.

Usher syndrome is an inherited disease that causes serious hearing loss and retinitis pigmentosa, an eye disorder that causes your vision to get worse over time. It is the most common condition that affects both hearing and vision. There are three types of Usher syndrome: - People with type I are deaf from birth and have severe balance problems from a young age. Vision problems usually start by age 10 and lead to blindness. - People with type II have moderate to severe hearing loss and normal balance. Vision problems start in the early teens and get worse more slowly than in type I. - People with type III are born with normal hearing and near-normal balance but develop vision problems and then hearing loss. There is no cure. Tools such as hearing aids or cochlear implants can help some people. Training such as Braille instruction, low-vision services, or auditory training can also help.

Summary : There are many problems that can keep a woman from enjoying sex. They include - Lack of sexual desire - Inability to become aroused - Lack of orgasm, or sexual climax - Painful intercourse These problems may have physical or psychological causes. Physical causes may include conditions like diabetes, heart disease, nerve disorders, or hormone problems. Some drugs can also affect desire and function. Psychological causes may include work-related stress and anxiety. They may also include depression or concerns about marriage or relationship problems. For some women, the problem results from past sexual trauma. Occasional problems with sexual function are common. If problems last more than a few months or cause distress for you or your partner, you should see your health care provider.

The mission of the National Institute of Neurological Disorders and Stroke (NINDS) is to seek fundamental knowledge about the brain and nervous system and to use that knowledge to reduce the burden of neurological disease. The NINDS is a component of the National Institutes of Health, the leading supporter of biomedical research in the world. Current research efforts include gaining a better understanding of how the central nervous system responds to inflammation in the brain, as well as to better understand the molecular mechanisms involved in the protection and disruption of the blood-brain barrier, which could lead to the development of new treatments for several neuroinflammatory diseases such as meningitis and encephalitis.

There is currently no effective way to treat mitochondria abnormalities in KSS. Treatment is generally symptomatic and supportive. Management of KSS involves multiple specialties depending on the organs involved. The most essential is a regular and long-term follow-up with cardiologists. Conduction problems of heart impulse like heart block may be treated with a pacemaker. Other consultations may include audiology, ophthalmology, endocrinology, neurology, and neuropsychiatry. Hearing aids may be required. There is typically no treatment for limitation in eye movement. Endocrinology abnormalities can be treated with drugs.

How might Ehlers-Danlos syndrome, dermatosparaxis type be treated? The treatment of Ehlers-Danlos syndrome (EDS), dermatosparaxis type is focused on preventing serious complications and relieving associated signs and symptoms. For example, physical therapy may be recommended in children with moderate to severe joint hypermobility. Assistive devices such as braces, wheelchairs, or scooters may also be necessary depending on the severity of joint instability. Hernias may be treated with surgery. Because EDS, dermatosparaxis type is associated with extremely fragile skin, affected people, especially children, may need to use protective bandages or pads over exposed areas, such as the knees, shins, and forehead. Heavy exercise and contact sports may also need to be avoided due to skin fragility and easy bruising. Please speak to your healthcare provider if you have any questions about your personal medical management plan.

What causes Norum disease? Norum disease is caused by defects in the LCAT gene. The clinical manifestations of LCAT deficiency are probably due to a defect in LCAT-mediated cholesterol ester formation and, therefore, accumulation of unesterified cholesterol in certain tissues, such as the cornea, kidneys, and erythrocytes (red blood cells).

COG5-congenital disorder of glycosylation (COG5-CDG, formerly known as congenital disorder of glycosylation type IIi) is an inherited condition that causes neurological problems and other abnormalities. The pattern and severity of this disorder's signs and symptoms vary among affected individuals. Individuals with COG5-CDG typically develop signs and symptoms of the condition during infancy. These individuals often have weak muscle tone (hypotonia) and delayed development. Other neurological features include moderate to severe intellectual disability, poor coordination, and difficulty walking. Some affected individuals never learn to speak. Other features of COG5-CDG include short stature, an unusually small head size (microcephaly), and distinctive facial features, which can include ears that are set low and rotated backward, a short neck with a low hairline in the back, and a prominent nose. Less commonly, affected individuals can have hearing loss caused by changes in the inner ear (sensorineural hearing loss), vision impairment, damage to the nerves that control bladder function (a condition called neurogenic bladder), liver disease, and joint deformities (contractures).

SCOT deficiency is a metabolic disease that is caused by reduced or missing levels of 3-ketoacid CoA transferase. This enzyme is necessary for the body to use ketones. Ketones are substances produced when fat cells break down and are an important source of energy, especially when there is a shortage of glucose. SCOT deficiency is characterized by intermittent ketoacidosis, with the first episode often occurring in newborns or infants (6 to 20 months). In ketoacidosis ketones build-up in the body. Symptoms of ketoacidosis may vary but can include trouble breathing, poor feeding, vomiting, lethargy, unconsciousness, and coma. Crises need to be addressed immediately. Fortunately these crises tend to respond well to IV fluids including glucose and sodium bicarbonate. Patients with SCOT defiency are symptom free between episodes. This deficiency can be caused by mutations in the OXCT1 gene.

Older age is a risk factor for heart valve disease. As you age, your heart valves thicken and become stiffer. Also, people are living longer now than in the past. As a result, heart valve disease has become an increasing problem.
People who have a history of infective endocarditis (IE), rheumatic fever, heart attack, or heart failureor previous heart valve diseasealso are at higher risk for heart valve disease. In addition, having risk factors for IE, such as intravenous drug use, increases the risk of heart valve disease.
You're also at higher risk for heart valve disease if you have risk factors for coronary heart disease. These risk factors include high blood cholesterol, high blood pressure, smoking, insulin resistance, diabetes, overweight or obesity, lack of physical activity, and a family history of early heart disease.
Some people are born with an aortic valve that has two flaps instead of three. Sometimes an aortic valve may have three flaps, but two flaps are fused together and act as one flap. This is called a bicuspid or bicommissural aortic valve. People who have this congenital condition are more likely to develop aortic heart valve disease.

Mutations in the MYH7 gene cause myosin storage myopathy. The MYH7 gene 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, one of two types of fibers that make up the muscles that the body uses for movement. Cardiac -myosin heavy chain is the major component of the thick filament in muscle cell structures called sarcomeres. Sarcomeres, which are made up of thick and thin filaments, are the basic units of muscle contraction. The overlapping thick and thin filaments attach to each other and release, which allows the filaments to move relative to one another so that muscles can contract. Mutations in the MYH7 gene lead to the production of an altered cardiac -myosin heavy chain protein, which is thought to be less able to form thick filaments. The altered proteins accumulate in type I skeletal muscle fibers, forming the protein clumps characteristic of the disorder. It is unclear how these changes lead to muscle weakness in people with myosin storage myopathy.

X-linked visceral heterotaxy type 1 is a very rare form of heterotaxy that has only been reported in a few families. Heterotaxy is the right/left transposition of thoracic and/or abdominal organs. This condition is caused by mutations in the ZIC3 gene, is inherited in an X-linked recessive fashion, and is usually seen in males. Physical features include heart abnormalities such as dextrocardia, transposition of great vessels, ventricular septal defect, patent ductus arteriosus, pulmonic stenosis; situs inversus, and missing (asplenia) and/or extra spleens (polysplenia). Affected individuals can also experience abnormalities in the development of the midline of the body, which can cause holoprosencephaly , myelomeningocele, urological anomalies, widely spaced eyes (hypertelorism), cleft palate, and abnormalities of the sacral spine and anus. Heterotaxia with recurrent respiratory infections are called primary ciliary dyskinesia.

The outcome of aphasia is difficult to predict given the wide range of variability of the condition. Generally, people who are younger or have less extensive brain damage fare better. The location of the injury is also important and is another clue to prognosis. In general, people tend to recover skills in language comprehension more completely than those skills involving expression.

The inheritance pattern of mannose-binding lectin deficiency is unclear. Some reports show that having a disease-associated mutation in one copy of the MBL2 gene in each cell can lead to the condition, while other reports state that a mutation in both copies of the gene is necessary. It is important to note that people inherit an increased risk of developing mannose-binding lectin deficiency, not the condition itself. Not all people who inherit mutations in this gene will develop the condition.

Sodium is found in salt and other foods. Most canned foods and frozen dinners contain large amounts of sodium. Too much sodium makes you thirsty. But if you drink more fluid, your heart has to work harder to pump the fluid through your body. Over time, this can cause high blood pressure and congestive heart failure.
Try to eat fresh foods that are naturally low in sodium Look for products labeled low sodium.
Do not use salt substitutes because they contain potassium. Talk with a dietitian about spices you can use to flavor your food. The dietitian can help you find spice blends without sodium or potassium.
