Arts syndrome appears to be extremely rare. Only a few families with this disorder have been described in the medical literature.
Sjogren's syndrome is a disease that causes dryness in your mouth and eyes. It can also lead to dryness in other places that need moisture, such as your nose, throat and skin. Most people who get Sjogren's syndrome are older than 40. Nine of 10 are women. Sjogren's syndrome is sometimes linked to rheumatic problems such as rheumatoid arthritis. Sjogren's syndrome is an autoimmune disease. If you have an autoimmune disease, your immune system, which is supposed to fight disease, mistakenly attacks parts of your own body. In Sjogren's syndrome, your immune system attacks the glands that make tears and saliva. It may also affect your joints, lungs, kidneys, blood vessels, digestive organs and nerves. The main symptoms are: - Dry eyes - Dry mouth Treatment focuses on relieving symptoms. NIH: National Institute of Arthritis and Musculoskeletal and Skin Diseases
Early identification of and treatment for individuals with neuroleptic malignant syndrome improves outcome. If clinically indicated, a low potency neuroleptic can be reintroduced very slowly when the individual recovers, although there is a risk that the syndrome might recur. Another alternative is to substitute another class of drugs for the neuroleptic. Anesthesia may be a risk to individuals who have experienced neuroleptic malignant syndrome.
A leukodystrophy is a type of rare genetic disorder that affects the brain, spinal cord, and other nerves in the body. It is caused by destruction of the white matter of the brain. The white matter degrades due to defects of the myelin, which is a fatty covering that insulates nerves in the brain. Myelin is needed to protect the nerves and the nerves can't function normally without it. These disorders are progressive, meaning they tend to get worse with time. The leukodystrophies are a group of disorders caused by spelling mistakes (mutations) in the genes involved in making myelin. Specific leukodystrophies include metachromatic leukodystrophy, Krabbe leukodystrophy, X-linked adrenoleukodystrophy, Pelizaeus-Merzbacher disease, Canavan disease, and Alexander disease. The most common symptom of a leukodystrophy is a decline in functioning of an infant or child who previously appeared healthy. This gradual loss may be seen with issues in body tone, movements, gait, speech, ability to eat, vision, hearing, and behavior.
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.
Hereditary angioedema is a disorder characterized by recurrent episodes of severe swelling (angioedema). The most common areas of the body to develop swelling are the limbs, face, intestinal tract, and airway. Minor trauma or stress may trigger an attack, but swelling often occurs without a known trigger. Episodes involving the intestinal tract cause severe abdominal pain, nausea, and vomiting. Swelling in the airway can restrict breathing and lead to life-threatening obstruction of the airway. About one-third of people with this condition develop a non-itchy rash called erythema marginatum during an attack. Symptoms of hereditary angioedema typically begin in childhood and worsen during puberty. On average, untreated individuals have an attack every 1 to 2 weeks, and most episodes last for about 3 to 4 days. The frequency and duration of attacks vary greatly among people with hereditary angioedema, even among people in the same family. There are three types of hereditary angioedema, called types I, II, and III, which can be distinguished by their underlying causes and levels of a protein called C1 inhibitor in the blood. The different types have similar signs and symptoms. Type III was originally thought to occur only in women, but families with affected males have been identified.
Signs of non-small cell lung cancer include a cough that doesn't go away and shortness of breath. Sometimes lung cancer does not cause any signs or symptoms. It may be found during a chest x-ray done for another condition. Signs and symptoms may be caused by lung cancer or by other conditions. Check with your doctor if you have any of the following: - Chest discomfort or pain. - A cough that doesnt go away or gets worse over time. - Trouble breathing. - Wheezing. - Blood in sputum (mucus coughed up from the lungs). - Hoarseness. - Loss of appetite. - Weight loss for no known reason. - Feeling very tired. - Trouble swallowing. - Swelling in the face and/or veins in the neck.
Ghosal hematodiaphyseal dysplasia results from mutations in the TBXAS1 gene. This gene provides instructions for making an enzyme called thromboxane A synthase 1, which acts as part of a chemical signaling pathway involved in normal blood clotting (hemostasis). Based on its role in Ghosal hematodiaphyseal dysplasia, researchers suspect that thromboxane A synthase 1 may also be important for bone remodeling, which is a normal process in which old bone is removed and new bone is created to replace it, and for the production of red blood cells in bone marrow. Mutations in the TBXAS1 gene severely reduce the activity of thromboxane A synthase 1. Studies suggest that a lack of this enzyme's activity may lead to abnormal bone remodeling and fibrosis of the bone marrow. However, the mechanism by which a shortage of thromboxane A synthase 1 activity leads to the particular abnormalities characteristic of Ghosal hematodiaphyseal dysplasia is unclear.
Lattice corneal dystrophy type I is one of the most common disorders in a group of conditions that are characterized by protein deposits in the cornea (corneal dystrophies); however, it is still a rare condition. The prevalence of lattice corneal dystrophy type I is unknown.
The National Institute of Neurological Disorders and Stroke, a unit of the National Institutes of Health (NIH) within the U.S. Department of Health and Human Services, is the nations leading federal funder of research on disorders of the brain and nervous system. The NINDS sponsors research on tremor both at its facilities at the NIH and through grants to medical centers. Scientists are evaluating the effectiveness of certain drugs and searching for genes that can cause certain forms of tremor.
Wolfram syndrome, which is also known by the acronym DIDMOAD, is an inherited condition characterized by diabetes insipidus (DI), childhood-onset diabetes mellitus (DM), a gradual loss of vision caused by optic atrophy (OA), and deafness (D). There are two types of Wolfram syndrome (type 1 and type 2) which are primarily differentiated by their genetic cause. Type 1 is caused by changes (mutations) in the WFS1 gene, while type 2 is caused by mutations in the CISD2 gene. Both forms are inherited in an autosomal recessive manner. Treatment is symptomatic and supportive.
What causes multifocal choroiditis? Multifocal choroiditis occurs spontaneously and the cause is not currently known (idiopathic). It is possible that a bacterial or viral infection may trigger an immune response that causes the inflammation seen with MFC, though more research is needed in this area.

How might punctate palmoplantar keratoderma type 1 be treated? Treatment options for this condition generally include topical salicylic acid, mechanical debridement, excision, and systemic retinoids. These therapies can lead to a temporary decrease in skin thickness and softening of the skin. Unfortunately, in many cases, medical and surgical treatment for punctate keratodermas do not provide consistent or long-lasting results. In general, there has been some reported success using keratolytics such as corticosteroids, urea, salicylic acid, lactic acid, or Vitamin A. Systemic therapy using vitamin D analogues, aromatic retinoids, and 5-fluorouracil has also been used. However, individuals with successful resolution of lesions often relapse unless they are maintained on chronic low-dose therapy. These topical and systemic treatments carry a variety of side effects. Surgery (including excision and skin grafting) for punctate keratodermas has been used on lesions resistant to medical treatment, but healing after surgical treatment can be difficult. CO2 laser ablation has also been attempted and reportedly produces good results for limited areas of hyperkeratosis of the palms.
If you have chronic hepatitis C, you should do things to take care of yourself, including eating a healthy diet. Avoid drinking alcohol, which can harm the liver. Talk with your doctor before taking vitamins and other supplements.
Summary : Normally, if you get hurt, your body forms a blood clot to stop the bleeding. Some people get too many clots or their blood clots abnormally. Many conditions can cause the blood to clot too much or prevent blood clots from dissolving properly. Risk factors for excessive blood clotting include - Certain genetic disorders - Atherosclerosis - Diabetes - Atrial fibrillation - Overweight, obesity, and metabolic syndrome - Some medicines - Smoking Blood clots can form in, or travel to, the blood vessels in the brain, heart, kidneys, lungs, and limbs. A clot in the veins deep in the limbs is called deep vein thrombosis (DVT). DVT usually affects the deep veins of the legs. If a blood clot in a deep vein breaks off and travels through the bloodstream to the lungs and blocks blood flow, the condition is called pulmonary embolism. Other complications of blood clots include stroke, heart attack, kidney problems and kidney failure, and pregnancy-related problems. Treatments for blood clots include blood thinners and other medicines.
What causes chromosome 4q deletion? People with chromosome 4q deletion are missing genetic material located on the long arm (q) of chromosome 4 in each cell. Scientists suspect that many of the features seen in people affected by this condition are caused by the deletion and/or disruption of certain genes found on 4q. The severity of the condition and the associated signs and symptoms vary depending on the size and location of the deletion and which genes are involved. For example, deletion of the following genes may contribute to the features seen in some affected people: BMP3 - skeletal abnormalities and short stature SEC31A - distinctive craniofacial features PKD2 - kidney abnormalities GRID2, NEUROG2 - neurological problems such as seizures, hypotonia, and delayed motor development (i.e. sitting up, walking, etc) ANK2, HAND2 - heart defects and/or arrhythmias FGF2 - limb (arms and legs) abnormalities Researchers are working to learn more about the other genes on 4q that may contribute to the features seen in people with a chromosome 4q deletion.
How might acquired pure red cell aplasia be treated? The main goals of treatment for pure red cell aplasia (PRCA) are to restore the production of red blood cells, maintain adequate hemoglobin levels, and treat underlying disorders that may be causing the condition. The initial treatment plan typically includes blood transfusions for individuals who are severely anemic and have cardiorespiratory failure. PRCA due to medication or infections is usually reversible within a few months. Therefore, medications that may be causing the condition should be discontinued, and infections that may cause the condition should be treated. Underlying conditions that may cause PRCA such as a thymoma, hematological cancers, solid tumors, and systemic lupus erythematosus (SLE) should be treated as necessary as well. When the condition is idiopathic (of unknown cause) or due to an autoimmune disorder, PRCA is typically initially treated with corticosteroids. It has been reported that individuals who seem to be resistant to treatment may respond to a single course of intravenous immunoglobulin (IVIG,) while others have responded to a single dose. In the United States, financial issues may make it difficult to obtain this treatment because IVIG is expensive and is not approved by the Food and Drug Administration to treat PRCA. Additional and more detailed information about the management of acquired PRCA may be found on eMedicine's web site and can be viewed by clicking here.
What symptoms are associated with granuloma annulare? People with this condition usually notice a ring of small, firm bumps (papules) over the backs of the forearms, hands or feet. Occasionally, multiple rings may be found. Rarely, granuloma annulare may appear as a firm nodule under the skin of the arms or legs.
DICER1 syndrome is a rare condition; its prevalence is unknown.
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. NINDS researchers are working to identify signaling pathways in the nervous system, with the hope of eventually developing drugs and techniques to help diagnose and treat NF. Understanding the natural history of tumors in NF and determining possible factors that may regulate their growth patterns is another aim of NIH researchers Ongoing research continues to discover additional genes that appear to play a role in NF-related tumor suppression or growth Continuing research on these genes and their proteins is beginning to reveal how this novel family of growth regulators controls how and where tumors form and grow Researchers also hope to develop new and more effective treatments for neurofibromatosis. Several agents have been tested or are under investigation for NF2, including the monoclonal antibody, bevacizumab, which improves hearing in some individuals with NF2.Because schwannomas are particularly hard to treat tumors, NINDS researchers are developing a new treatment option, which uses a virus to kill tumor cells. Additional NINDS-funded researchers are testing novel radiation and chemotherapy regimens for NF1-related malignant tumors of the peripheral nerves.
Each form of porphyria results from mutations in one of these genes: ALAD, ALAS2, CPOX, FECH, HMBS, PPOX, UROD, or UROS. The genes related to porphyria provide instructions for making the enzymes needed to produce heme. Mutations in most of these genes reduce enzyme activity, which limits the amount of heme the body can produce. As a result, compounds called porphyrins and porphyrin precursors, which are formed during the process of heme production, can build up abnormally in the liver and other organs. When these substances accumulate in the skin and interact with sunlight, they cause the cutaneous forms of porphyria. The acute forms of the disease occur when porphyrins and porphyrin precursors build up in and damage the nervous system. One type of porphyria, porphyria cutanea tarda, results from both genetic and nongenetic factors. About 20 percent of cases are related to mutations in the UROD gene. The remaining cases are not associated with UROD gene mutations and are classified as sporadic. Many factors contribute to the development of porphyria cutanea tarda. These include an increased amount of iron in the liver, alcohol consumption, smoking, hepatitis C or HIV infection, or certain hormones. Mutations in the HFE gene (which cause an iron overload disorder called hemochromatosis) are also associated with porphyria cutanea tarda. Other, as-yet-unidentified genetic factors may also play a role in this form of porphyria.
Normally, if you get hurt, your body forms a blood clot to stop the bleeding. For blood to clot, your body needs cells called platelets and proteins known as clotting factors. If you have a bleeding disorder, you either do not have enough platelets or clotting factors or they don't work the way they should. Bleeding disorders can be the result of other diseases, such as severe liver disease. They can also be inherited. Hemophilia is an inherited bleeding disorder. Bleeding disorders can also be a side effect of medicines.
Stiff person syndrome (SPS) is a rare neurological disorder with features of an autoimmune disease. Symptoms may include muscle stiffness in the trunk and limbs, and heightened sensitivity to noise, touch, and emotional distress, which can set off muscle spasms. Affected people may also have abnormal postures, such as being hunched over. SPS affects twice as many women as men. It is frequently associated with other autoimmune diseases such as diabetes, thyroiditis, vitiligo, and pernicious anemia. The exact causes of SPS is not known. Treatment may involve high-dose diazepam, anti-convulsants, or intravenous immunoglobulin (IVIG).
How is nephrogenic diabetes insipidus inherited? When nephrogenic diabetes insipidus results from mutations in the AVPR2 gene, the condition has an X-linked recessive pattern of inheritance. The AVPR2 gene 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 usually has to occur in both copies of the gene to cause the disorder. However, some females who carry a single mutated copy of the AVPR2 gene have features of nephrogenic diabetes insipidus, including polyuria and polydipsia. A characteristic of X-linked inheritance is that fathers cannot pass X-linked traits to their sons.
A hernia happens when part of an internal organ or tissue bulges through a weak area of muscle. Most hernias are in the abdomen. There are several types of hernias, including - Inguinal, in the groin. This is the the most common type. - Umbilical, around the belly button - Incisional, through a scar - Hiatal, a small opening in the diaphragm that allows the upper part of the stomach to move up into the chest. - Congenital diaphragmatic, a birth defect that needs surgery Hernias are common. They can affect men, women, and children. A combination of muscle weakness and straining, such as with heavy lifting, might contribute. Some people are born with weak abdominal muscles and may be more likely to get a hernia. Treatment is usually surgery to repair the opening in the muscle wall. Untreated hernias can cause pain and health problems.
Signs and symptoms of childhood CNS germ cell tumors include unusual thirst, frequent urination, early puberty, or vision changes. Signs and symptoms depend on the following: - Where the tumor has formed. - The size of the tumor. - Whether the tumor makes hormones. Signs and symptoms may be caused by childhood CNS germ cell tumors or by other conditions. Check with your childs doctor if your child has any of the following: - Being very thirsty. - Making large amounts of urine that is clear or almost clear. - Frequent urination. - Bed wetting or getting up at night to urinate. - Trouble moving the eyes or trouble seeing clearly. - Loss of appetite. - Weight loss for no known reason. - Early or late puberty. - Short stature (being shorter than normal). - Headaches. - Nausea and vomiting. - Feeling very tired. - Having problems with school work.
Encephalitis is an inflammation of the brain. Usually the cause is a viral infection, but bacteria can also cause it. It can be mild or severe. Most cases are mild. You may have flu-like symptoms. With a mild case, you may just need rest, plenty of fluids, and a pain reliever. Severe cases need immediate treatment. Symptoms of severe cases include - Severe headache - Sudden fever - Drowsiness - Vomiting - Confusion - Seizures In babies, additional symptoms may include constant crying, poor feeding, body stiffness, and bulging in the soft spots of the skull. Severe cases may require a stay in the hospital. Treatments include oral and intravenous medicines to reduce inflammation and treat infection. Patients with breathing difficulties may need artificial respiration. Some people may need physical, speech, and occupational therapy once the illness is under control.

MMPSI is a rare condition. Although its prevalence is unknown, approximately 100 cases have been described in the medical literature.
Syndrome of inappropriate antidiuretic hormone (SIADH) occurs when an excessive amount of antidiuretic hormone is released resulting in water retention and a low sodium level. It is most common among older people. It has many causes including, but not limited too, pain, stress, exercise, a low blood sugar level, certain disorders of the heart, thyroid gland, kidneys, or adrenal glands, and the use of certain medications. Disorders of the lungs and certain cancers may increase the risk of developing SIADH. Treatment includes fluid restriction and sometimes the use of medications that decrease the effect of antidiuretic hormone on the kidneys.
Pain is a feeling set off in the nervous system. Acute pain lets you know that you may be injured or have a problem you need to take care of. Chronic pain is different. The pain signals go on for weeks, months, or even years. The original cause may have been an injury or infection. There may be an ongoing cause of pain, such as arthritis or cancer. But in some cases there is no clear cause. Problems that cause chronic pain include - Headache - Low back strain - Cancer - Arthritis - Pain from nerve damage Chronic pain usually cannot be cured. But treatments can help. They include medicines, acupuncture, electrical stimulation and surgery. Other treatments include psychotherapy, relaxation and meditation therapy, biofeedback, and behavior modification. NIH: National Institute of Neurological Disorders and Stroke
Schizencephaly is a rare congenital (present from birth) brain malformation in which abnormal slits or clefts form in the cerebral hemispheres of the brain. The signs and symptoms of this condition may include developmental delay, seizures, and problems with brain-spinal cord communication. Affected people may also have an abnormally small head (microcephaly); hydrocephalus; intellectual disability; partial or complete paralysis; and/or poor muscle tone (hypotonia). Severity of symptoms depends on many factors including the extent of the clefting and whether or not other brain abnormalities are present. Although the exact cause of schizencephaly is unknown, it has been linked to a variety of genetic and non-genetic factors. Treatment generally consists of physical therapy and drugs to prevent seizures. In cases that are complicated by hydrocephalus, a surgically implanted tube, called a shunt, is often used to divert fluid to another area of the body where it can be absorbed.
When a person has diverticula that do not cause diverticulitis or diverticular bleeding, the condition is called diverticulosis. Most people with diverticulosis do not have symptoms. Some people with diverticulosis have constipation or diarrhea. People may also have chronic - cramping or pain in the lower abdomenthe area between the chest and hips - bloating Other conditions, such as irritable bowel syndrome and stomach ulcers, cause similar problems, so these symptoms do not always mean a person has diverticulosis. People with these symptoms should see their health care provider.
Familial progressive cardiac conduction defect (PCCD) is a is a cardiac (heart) conduction disorder that may progress to complete heart block. Affected people may not have any symptoms, or the condition may cause shortness of breath, dizziness, fainting, abdominal pain, heart failure, or sudden death. Mutations in several genes, including the SCN5A, SCN1B and TRPM4 genes, can cause PCCD. Several other genes may be the cause when PCCD occurs with congenital heart disease. Familial PCCD is usually inherited in an autosomal dominant manner. However, not all people that have the mutated gene will have the condition; in those that do, symptoms and severity can vary (known as reduced penetrance and variable expressivity). Autosomal recessive inheritance and sporadic cases have been reported, but are rare. Treatment includes implantation of a pacemaker.
Is genetic testing available for nephrogenic diabetes insipidus? Yes. GeneTests lists laboratories offering clinical genetic testing for both X-linked and autosomal types of nephrogenic diabetes insipidus. Clinical genetic tests are ordered to help diagnose a person or family and to aid in decisions regarding medical care or reproductive issues. Talk to your health care provider or a genetic professional to learn more about your testing options.
Paroxysmal choreoathetosis is a movement disorder characterized by episodes or attacks of involuntary movements of the limbs, trunk, and facial muscles. The disorder may occur in several members of a family, or in only a single family member. Prior to an attack some individuals experience tightening of muscles or other physical symptoms. Involuntary movements precipitate some attacks, and other attacks occur when the individual has consumed alcohol or caffeine, or is tired or stressed. Attacks can last from 10 seconds to over an hour. Some individuals have lingering muscle tightness after an attack. Paroxysmal choreoathetosis frequently begins in early adolescence. A gene associated with the disorder has been discovered. The same gene is also associated with epilepsy.
Summary : Hormones are your body's chemical messengers. They travel in your bloodstream to tissues or organs. They work slowly, over time, and affect many different processes, including - Growth and development - Metabolism - how your body gets energy from the foods you eat - Sexual function - Reproduction - Mood Endocrine glands, which are special groups of cells, make hormones. The major endocrine glands are the pituitary, pineal, thymus, thyroid, adrenal glands, and pancreas. In addition, men produce hormones in their testes and women produce them in their ovaries. Hormones are powerful. It takes only a tiny amount to cause big changes in cells or even your whole body. That is why too much or too little of a certain hormone can be serious. Laboratory tests can measure the hormone levels in your blood, urine, or saliva. Your health care provider may perform these tests if you have symptoms of a hormone disorder. Home pregnancy tests are similar - they test for pregnancy hormones in your urine.
Summary : Every racial or ethnic group has specific health concerns. Differences in the health of groups can result from - Genetics - Environmental factors - Access to care - Cultural factors On this page, you'll find links to health issues that affect Hispanic Americans.
Floating-Harbor syndrome is a genetic disorder that was named for the first two identified patients who were seen at Boston Floating Hospital and Harbor General Hospital in California. The main characteristics of this syndrome are short stature, delayed bone growth, delay in expressive language, and distinct facial features. The exact cause of Floating-Harbor syndrome is not known. Treatment is symptomatic and supportive.
How might alpha-thalassemia be treated? Treatment of alpha-thalassemia often includes blood transfusions to provide healthy blood cells that have normal hemoglobin. Bone marrow transplant has helped to cure a small number of individuals with severe alpha-thalassemia.
What causes reticulohistiocytoma? While it is known that reticulohistiocytoma (RH) develop due to a rapid production of immune cells (histiocytes) in the skin or soft tissues, the cause of this process is not currently known.

Dystonia 6 is one of many forms of dystonia, which is a group of conditions characterized by involuntary movements, twisting (torsion) and tensing of various muscles, and unusual positioning of affected body parts. Dystonia 6 can appear at any age from childhood through adulthood; the average age of onset is 18. The signs and symptoms of dystonia 6 vary among affected individuals. The disorder usually first impacts muscles of the head and neck, causing problems with speaking (dysarthria) and eating (dysphagia). Eyelid twitching (blepharospasm) may also occur. Involvement of one or more limbs is common, and in some cases occurs before the head and neck problems. Dystonia 6 gradually gets worse, and it may eventually involve most of the body.
How might a preauricular sinus be treated? The majority of preauricular sinuses do not cause symptoms or problems unless they become infected. Common signs of infection include swelling, redness, fluid drainage, and pain. In these cases, treatment typically includes systemic antibiotics. If an abscess is present, it will likely need to be incised and drained. There are differing opinions in the medical literature about the indications for surgical removal of preauricular sinuses. Some believe that even asymptomatic sinuses should be removed. Others believe that surgery is indicated if infection or other complications arise.
Coats disease is an eye disorder characterized by abnormal development of the blood vessels in the retina (retinal telangiectasia). Most affected people begin showing symptoms of the condition in childhood. Early signs and symptoms vary but may include vision loss, crossed eyes (strabismus), and a white mass in the pupil behind the lens of the eye (leukocoria). Overtime, coats disease may also lead to retinal detachment, glaucoma, and clouding of the lens of the eye (cataracts) as the disease progresses. In most cases, only one eye is affected (unilateral). The exact underlying cause is not known but some cases may be due to somatic mutations in the NDP gene. Treatment depends on the symptoms present and may include cryotherapy, laser therapy, and/or surgery.

Hirschsprung* disease (HD) is a disease of the large intestine that causes severe constipation or intestinal obstruction. Constipation means stool moves through the intestines slower than usual. Bowel movements occur less often than normal and stools are difficult to pass. Some children with HD cant pass stool at all, which can result in the complete blockage of the intestines, a condition called intestinal obstruction. People with HD are born with it and are usually diagnosed when they are infants. Less severe cases are sometimes diagnosed when a child is older. An HD diagnosis in an adult is rare. *See Pronunciation Guide for tips on how to say the words in bold type.
You can't prevent inherited types of cardiomyopathy. However, you can take steps to lower your risk for diseases or conditions that may lead to or complicate cardiomyopathy. Examples includecoronary heart disease,high blood pressure, andheart attack. Your doctor may advise you to make heart-healthy lifestyle changes, such as: Avoiding the use of alcohol and illegal drugs Getting enough sleep and rest Heart-healthy eating Physicalactivity Quitting smoking Managing stress Your cardiomyopathy may be due to an underlying disease or condition. If you treat that condition early enough, you may be able to prevent cardiomyopathy complications. For example, to control high blood pressure,high blood cholesterol, and diabetes: Follow your doctors advice about lifestyle changes. Get regular checkups with your doctor. Take all of your medicines as your doctor prescribes.
Summary : Critical care helps people with life-threatening injuries and illnesses. It might treat problems such as complications from surgery, accidents, infections, and severe breathing problems. It involves close, constant attention by a team of specially-trained health care providers. Critical care usually takes place in an intensive care unit (ICU) or trauma center. Monitors, intravenous (IV) tubes, feeding tubes, catheters, breathing machines, and other equipment are common in critical care units. They can keep a person alive, but can also increase the risk of infection. Many patients in critical care recover, but some die. Having advance directives in place is important. They help health care providers and family members make end-of-life decisions if you are not able to make them.
Symptoms of foodborne illnesses depend on the cause. Common symptoms of many foodborne illnesses include - vomiting - diarrhea or bloody diarrhea - abdominal pain - fever - chills Symptoms can range from mild to serious and can last from a few hours to several days. C. botulinum and some chemicals affect the nervous system, causing symptoms such as - headache - tingling or numbness of the skin - blurred vision - weakness - dizziness - paralysis
Researchers have not found a way to prevent IgA nephropathy. People with a family history of IgA nephropathy should talk with their health care provider to find out what steps they can take to keep their kidneys healthy, such as controlling their blood pressure and keeping their blood cholesterol at healthy levels.
Timothy syndrome is a type of long QT syndrome. It affects many parts of the body including the heart, fingers, toes, face, and the nervous system. It is characterized by long QT syndrome, although some people with Timothy syndrome also have other heart defects that affect the hearts ability to pump blood effectively. Other symptoms of Timothy syndrome include fusion of the skin between fingers or toes and distinctive facial features. In addition, many children with this syndrome have developmental delay and characteristic features of autism. Mental retardation and seizures can also occur in children with Timothy syndrome. There are two forms of Timothy syndrome. Type 1 includes all of the characteristic features described. Type 2 causes a more severe form of long QT syndrome and does not appear to cause fusion of skin between fingers or toes. All cases of Timothy syndrome appear to be due to changes in the CACNA1C gene. This syndrome is inherited in an autosomal dominant manner. However, most cases are not inherited from an affected parent, but occur for the first time in a family due to a spontaneous or random change in the CACNA1C gene.
Aniridia 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 approximately two-thirds of cases, an affected person inherits the mutation from one affected parent. The remaining one-third of cases result from new mutations in the gene and occur in people with no history of the disorder in their family.

What are the signs and symptoms of Familial avascular necrosis of the femoral head? The Human Phenotype Ontology provides the following list of signs and symptoms for Familial avascular necrosis of the femoral head. 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) Autosomal dominant inheritance - Avascular necrosis of the capital femoral epiphysis - 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.

Cancers that are known collectively as head and neck cancers usually begin in the squamous cells that line the moist, mucosal surfaces inside the head and neck (for example, inside the mouth, the nose, and the throat). These squamous cell cancers are often referred to as squamous cell carcinomas of the head and neck. At least 75 % of head and neck cancers are caused by tobacco and alcohol use. Infection with cancer-causing types of human papillomavirus (HPV), especially HPV-16, is a risk factor for some types of head and neck cancers. The symptoms of head and neck cancers may include a lump or a sore that does not heal, a sore throat that does not go away, difficulty in swallowing, and a change or hoarseness in the voice. Treatment for head and neck cancer can include surgery, radiation therapy, chemotherapy, targeted therapy, or a combination of treatments.
How is cleidocranial dysplasia inherited? Cleidocranial dysplasia is inherited in an autosomal dominant manner, which means one copy of the altered gene in each cell is sufficient to cause the disorder. In some cases, an affected person inherits the mutation from one affected parent. Other cases may result from de novo mutations (new mutations) in the gene. These cases occur in people with no history of the disorder in their family.
Neurofibromatosis is a genetic disorder of the nervous system. It mainly affects how nerve cells form and grow. It causes tumors to grow on nerves. You can get neurofibromatosis from your parents, or it can happen because of a mutation (change) in your genes. Once you have it, you can pass it along to your children. Usually the tumors are benign, but sometimes they can become cancerous. There are three types of neurofibromatosis: - Type 1 (NF1) causes skin changes and deformed bones. It usually starts in childhood. Sometimes the symptoms are present at birth. - Type 2 (NF2) causes hearing loss, ringing in the ears, and poor balance. Symptoms often start in the teen years. - Schwannomatosis causes intense pain. It is the rarest type. Doctors diagnose the different types based on the symptoms. Genetic testing is also used to diagnose NF1 and NF2. There is no cure. Treatment can help control symptoms. Depending on the type of disease and how serious it is, treatment may include surgery to remove tumors, radiation therapy, and medicines. NIH: National Institute of Neurological Disorders and Stroke
Autosomal recessive cerebellar ataxia type 1 (ARCA1) is a condition characterized by progressive problems with movement due to a loss (atrophy) of nerve cells in the part of the brain that coordinates movement (the cerebellum). Signs and symptoms of the disorder first appear in early to mid-adulthood. People with this condition initially experience impaired speech (dysarthria), problems with coordination and balance (ataxia), or both. They may also have difficulty with movements that involve judging distance or scale (dysmetria). Other features of ARCA1 include abnormal eye movements (nystagmus) and problems following the movements of objects with the eyes. The movement problems are slowly progressive, often resulting in the need for a cane, walker, or wheelchair.
Nonsyndromic aplasia cutis congenita is a condition in which babies are born with localized areas of missing skin (lesions). These areas resemble ulcers or open wounds, although they are sometimes already healed at birth. Lesions most commonly occur on the top of the head (skull vertex), although they can be found on the torso or limbs. In some cases, the bone and other tissues under the skin defect are also underdeveloped. Most affected babies have a single lesion. The lesions vary in size and can be differently shaped: some are round or oval, others rectangular, and still others star-shaped. They usually leave a scar after they heal. When the scalp is involved, there may be an absence of hair growth (alopecia) in the affected area. When the underlying bone and other tissues are involved, affected individuals are at higher risk of infections. If these severe defects occur on the head, the membrane that covers the brain (the dura mater) may be exposed, and life-threatening bleeding may occur from nearby vessels. Skin lesions are typically the only feature of nonsyndromic aplasia cutis congenita, although other skin problems and abnormalities of the bones and other tissues occur rarely. However, the characteristic skin lesions can occur as one of many symptoms in other conditions, including Johanson-Blizzard syndrome and Adams-Oliver syndrome. These instances are described as syndromic aplasia cutis congenita.
How might osteochondritis dissecans be treated? The primary aim of treatment for osteochondritis dissecans is to restore normal function of the affected joint, relieve pain and prevent osteoarthritis. Treatment for the condition varies depending on many factors including the age of the affected person and the severity of the symptoms. In children and young teens, osteochondritis dissecans often heals overtime without surgical treatment. These cases are often managed with rest and in some cases, crutches and/or splinting to relieve pain and swelling. If non-surgical treatments are not successful or the case is particularly severe (i.e. the cartilage and bone are moving around within the joint space), surgery may be recommended. Following surgery, physical therapy is often necessary to improve the strength and range of motion of the affected joint.
People at risk for cough include those who: Are exposed to things that irritate their airways (called irritants) or things that they're allergic to (called allergens). Examples of irritants are cigarette smoke, air pollution, paint fumes, and scented products. Examples of allergens are dust, animal dander, mold, and pollens from trees, grasses, and flowers. Have certain conditions that irritate the lungs, such as asthma, sinus infections, colds, or gastroesophageal reflux disease. Smoke. Smoking can irritate your lungs and cause coughing. Smoking and/or exposure to secondhand smoke also can lead to medical conditions that can cause a cough. Take certain medicines, such as ACE inhibitors and beta blockers. ACE inhibitors are used to treat high blood pressure (HBP). Beta blockers are used to treat HBP, migraine headaches, and glaucoma. Women are more likely than men to develop a chronic cough. For more information about the substances and conditions that put you at risk for cough, go to "What Causes Cough?"
Amyloidosis is a group of diseases in which a protein, called amyloid, builds up in the body's organs and tissues. Amyloidosis AA is also referred to as Secondary amyloidosis or Inflammatory amyloidosis. This disease is caused by a long-lasting infection or inflammatory disease such as rheumatoid arthritis, familial Mediterranean fever, or osteomyelitis. Infection or inflammation in the body causes an increased amount of a specific protein called serum amyloid A (SAA) protein. In this disease, part of the SAA protein forms deposits called "amyloid fibrils". These desposits occur in the space around the cells of certain tissues of the body. Amyloidosis AA usually begins as a disease in the kidneys, but other organs can be affected such as the liver and spleen. Medical or surgical treatment of the underlying infection or inflammatory disease can slow down or stop the progression of this condition.
For most people CMV infection is not a problem. However, two groups of people are at high risk of neurological or other severe symptoms that may lead to long-term effects: - Unborn infants whose mothers have CMV infection. CMVis the most common congenital infection in the U.S. Most infants will have no permanent health consequences, but a small number will have at birth or will develop long-term neurological conditions, such as hearing loss, visual impairment, seizures, or disabilities f mental or physical function. The highest risk of these severe effects on the fetus is for women who acquire CMV infection for the first time during pregnancy. The risk is much lower for women who have had CMV infection in the past before pregnancy. - Immunocompromised individuals. CMV infection may be severe in solid organ or blood cell transplant recipients, people with untreated or end-stage HIV-AIDS, or others with altered immune function. Infection may affect the brain (encephalitis), spinal cord (myelitis), eye (retinitis), or other organs such as the lungs (pneumonia) or intestinal gract (gastritis, enteritis, or colitis). In addition, transplant recipients may develop organ rejection or graft-versus-host disease associated with CMV infection.
Too much glucose in the blood for a long time can cause diabetes problems. This high blood glucose, also called blood sugar, can damage many parts of the body, such as the heart, blood vessels, eyes, and kidneys. Heart and blood vessel disease can lead to heart attacks and strokes, the leading causes of death for people with diabetes. You can do a lot to prevent or slow down diabetes problems. This booklet is about heart and blood vessel problems caused by diabetes. You will learn the things you can do each day and during each year to stay healthy and prevent diabetes problems.
Translational research grows out of basic research. It creates new medicines, devices, or behavioral interventions aimed at preventing, diagnosing, or treating a disease. An important goal of Alzheimers translational research is to increase the number and variety of potential new medicines and other interventions that are approved for testing in humans. Scientists also examine medicines approved to treat other diseases to see they might be effective in people with Alzheimers. The most promising interventions are tested in test-tube and animal studies to make sure they are safe and effective. Currently, a number of different substances are under development that may one day be used to treat the symptoms of Alzheimers disease or mild cognitive impairment. See the latest Alzheimers Disease Progress Report to read about results of NIA-supported Alzheimers research.
The inherited form of factor X deficiency, known as congenital factor X deficiency, is caused by mutations in the F10 gene, which provides instructions for making a protein called coagulation factor X. This protein plays a critical role in the coagulation system, which is a series of chemical reactions that forms blood clots in response to injury. Some F10 gene mutations that cause factor X deficiency reduce the amount of coagulation factor X in the bloodstream, resulting in a form of the disorder called type I. Other F10 gene mutations result in the production of a coagulation factor X protein with impaired function, leading to type II factor X deficiency. Reduced quantity or function of coagulation factor X prevents blood from clotting normally, causing episodes of abnormal bleeding that can be severe. A non-inherited form of the disorder, called acquired factor X deficiency, is more common than the congenital form. Acquired factor X deficiency can be caused by other disorders such as severe liver disease or systemic amyloidosis, a condition involving the accumulation of abnormal proteins called amyloids. Acquired factor X deficiency can also be caused by certain drugs such as medicines that prevent clotting, or by a deficiency of vitamin K.
Is radiation therapy a recommended treatment for microcystic adnexal carcinoma? Unfortunately, because microcystic adnexal carcinoma is a rare cancer, there is currently not enough information to determine if radiation therapy is an effective treatment for this disease. There are no guidelines for the use of radiation therapy as treatment for microcystic adnexal carcinoma, and little is known about the dose of radiation that might be needed to be effective. Two articles studying a total of 17 patients receiving radiation therapy for microcystic adnexal carcinoma have suggested that there may be a benefit of radiation therapy for decreasing the chances of the tumor regrowing (recurrence), and the authors suggest that this treatment could be considered if there is evidence that cancer cells remain after surgery, or in situations where additional surgery cannot be done. However, another article raises concerns about the use of radiation therapy considering the small number of patients studied, the report of one patient's disease potentially worsening after radiation therapy, and the belief that exposure to radiation may be a risk factor for the initial development of this tumor.
There are four common types of leukemia. They are chronic lymphocytic leukemia, chronic myeloid leukemia, acute myeloid leukemia, and acute lymphocytic leukemia. Chronic lymphocytic leukemia, chronic myeloid leukemia, and acute myeloid leukemia are diagnosed more often in older adults. Acute lymphocytic leukemia is found more often in children.

Holt-Oram syndrome is a genetic condition characterized by skeletal abnormalities of the hands and arms (upper limbs) and heart problems. Affected people have at least one bone abnormality in the wrist, many of which can be detected only by X-ray. Additional skeletal abnormalities may also be present. About 75% of affected people have heart problems, including congenital heart defects and/or cardiac conduction disease (an abnormality in the electrical system that coordinates contractions of the heart chambers). Holt-Oram syndrome is caused by mutations in the TBX5 gene and is inherited in an autosomal dominant manner. Most cases result from new mutations in the gene and occur in people with no family history of the condition.
Benign hereditary chorea (BHC) is a rare movement disorder that begins in infancy or childhood. Signs and symptoms in infants may include low muscle tone, involuntary movements (chorea), lung infections, and respiratory distress. Signs and symptoms in children may include delayed motor and walking milestones, jerky muscle movements (myoclonus), upper limb dystonia, motor tics, and vocal tics. The chorea often improves with time. In some cases, myoclonus persists or worsens. Children with BHC can have normal intellect, but may have learning and behavior problems. Other signs and symptoms include thyroid problems (e.g., hypothyroidism) and lung disease (e.g., recurring infections). Treatment is tailored to each child. Tetrabenazine and levodopa have been tried in individual cases with some success. BHC is caused by mutations in the NKX2-1 gene (also known as the TITF1 gene). It is passed through families in an autosomal dominant fashion.
What causes Madelung disease? The exact underlying cause of Madelung disease remains unknown, but several theories have been proposed. The body's inability to properly metabolize fat in affected people suggests that Madelung disease may be an endocrine disorder. An enzyme defect or a change in the surface of cells could prevent the breakdown of fat leading to the characteristic signs and symptoms of the condition. Alcohol consumption may also play a role in the development of Madelung disease since roughly 90% of affected people have a history of alcohol abuse. Madelung disease has also been linked to genetic factors. Rarely, more than one family member can be affected by this condition which suggests that it may be inherited in at least some cases. In the majority of these families, the mode of inheritance has not been determined. However, changes (mutations) in mitochondrial DNA have been identified in some families who have Madelung disease in combination with other conditions that affect many different systems of the body.
Intellectual disability-developmental delay-contractures syndrome is a rare, slowly progressive genetic disorder that is present at birth. It is characterized by contractures of the joints of the feet (arthrogryposis multiplex congenita), muscle degeneration (atrophy), mild intellectual disability and an impaired ability to move certain muscles of the eyes, face and tongue. Other symptoms might include spasticity and seizures. Intellectual disability-developmental delay-contractures syndrome is caused by mutations in the ZC4H2 gene and is inherited in an X-linked recessive fashion. Most people with intellectual disability-developmental delay-contractures syndrome are male; however carrier females have been reported to have mild symptoms. There is no known cure for intellectual disability-developmental delay-contractures syndrome. Treatment is symptomatic and supportive.
Fraser syndrome affects an estimated 1 in 200,000 newborns. The condition occurs in approximately 1 in 10,000 fetuses that do not survive to birth.

The prevalence of hereditary cerebral amyloid angiopathy is unknown. The Dutch type is the most common, with over 200 affected individuals reported in the scientific literature.
The NINDS supports research on neuromuscular disorders such as LEMS with the ultimate goal of finding ways to treat, prevent, and cure them.
What causes Troyer syndrome? Troyer syndrome is caused by mutations in the SPG20 gene. This gene gives the body instructions to make a protein called spartin, which is present in many body tissues, including those of the nervous system. However, the function of this protein is not fully understood. It is thought to play various roles needed for the functions of cells. Troyer syndrome is assumed to be caused by a loss of function of the spartin protein. More research on the normal functions of the spartin protein is needed to better understand exactly how mutations in the SPG20 gene cause the features of Troyer syndrome.
The prevalence of all hereditary spastic paraplegias combined is estimated to be 2 to 6 in 100,000 people worldwide. Spastic paraplegia type 7 likely accounts for only a small percentage of all spastic paraplegia cases.
Patients with glomerular disease have significant amounts of protein in the urine, which may be referred to as "nephrotic range" if levels are very high. Red blood cells in the urine are a frequent finding as well, particularly in some forms of glomerular disease. Urinalysis provides information about kidney damage by indicating levels of protein and red blood cells in the urine. Blood tests measure the levels of waste products such as creatinine and urea nitrogen to determine whether the filtering capacity of the kidneys is impaired. If these lab tests indicate kidney damage, the doctor may recommend ultrasound or an x ray to see whether the shape or size of the kidneys is abnormal. These tests are called renal imaging. But since glomerular disease causes problems at the cellular level, the doctor will probably also recommend a kidney biopsya procedure in which a needle is used to extract small pieces of tissue for examination with different types of microscopes, each of which shows a different aspect of the tissue. A biopsy may be helpful in confirming glomerular disease and identifying the cause.
Syndromic microphthalmia, type 3 is a rare condition that affects the eyes and other parts of the body. Babies with this condition are generally born without eyeballs (anophthalmia) or with eyes that are unusually small (microphthalmia). Both of these abnormalities can be associated with severe vision loss. Other signs and symptoms of syndromic microphthalmia, type 3 may include seizures, brain malformations, esophageal atresia, delayed motor development, learning disabilities, and sensorineural hearing loss. The condition is caused by changes (mutations) in the SOX2 gene and is inherited in an autosomal dominant manner. Treatment is based on the signs and symptoms present in each person.
How might Ehlers-Danlos syndrome progeroid type be treated? Individuals with Ehlers-Danlos Syndrome progeroid type can benefit from a variety of treatments depending on their symptoms. Affected children with weak muscle tone and delayed development might benefit from physiotherapy to improve muscle strength and coordination. Affected individuals with joint pain might benefit from anti-inflammatory drugs. Lifestyle changes or precautions during exercise or intense physical activity may be advised to reduce the chance of accidents to the skin and bone. It is recommended that affected individuals discuss treatment options with their healthcare provider.
The prevalence of this condition is unknown. Only a few affected individuals have been described in the medical literature.
Long QT syndrome is a disorder of the hearts electrical activity that can cause sudden, uncontrollable, and irregular heartbeats (arrhythmia), which may lead to sudden death. Long QT syndrome can be detected by electrocardiogram (EKG). It can be caused by a variety of different gene mutations (changes). It can also be acquired (noninherited) and may be brought on by certain medicines and other medical conditions.
Acromicric dysplasia is a rare disorder; its prevalence is unknown.
Fifth disease is a viral infection caused by parvovirus B19. The virus only infects humans; it's not the same parvovirus that dogs and cats can get. Fifth disease mostly affects children. Symptoms can include a low fever, cold symptoms, and a headache. Then you get a red rash on your face. It looks like a "slapped cheek." The rash can spread to the arms, legs, and trunk. Adults who get it might also have joint pain and swelling. Fifth disease spreads easily, through saliva and mucus. You can get it when an infected person coughs or sneezes. Frequently washing your hands might help prevent getting the virus. Most people become immune to the virus after having it once. Fifth disease is usually mild and goes away on its own. However, it can be serious if you - Are pregnant - Are anemic - Have cancer or a weak immune system Centers for Disease Control and Prevention

Signs and symptoms of chronic myelogenous leukemia include fever, night sweats, and tiredness. These and other signs and symptoms may be caused by CML or by other conditions. Check with your doctor if you have any of the following: - Feeling very tired. - Weight loss for no known reason. - Night sweats. - Fever. - Pain or a feeling of fullness below the ribs on the left side. Sometimes CML does not cause any symptoms at all.
How might chromosome 3p- syndrome be treated? Because chromosome 3p- syndrome affects many different systems of the body, medical management is often provided by a team of doctors and other healthcare professionals. Treatment for this deletion varies based on the signs and symptoms present in each person. For example, children with delayed motor milestones (i.e. walking) and/or muscle problems may be referred for physical or occupational therapy. Severe feeding difficulties may be treated temporarily with a nasogastric tube or a gastrostomy tube to ensure that a baby or child gets enough nutrients. Certain medications may be prescribed to treat seizures. Special education services are often necessary for children with intellectual disability. Surgery may be required to treat certain physical abnormalities such as cleft palate or congenital heart defects, if present. Please speak to your healthcare provider if you have any questions about your personal medical management plan.
Hereditary cerebral amyloid angiopathy caused by mutations in the APP, CST3, or ITM2B gene is inherited in an autosomal dominant pattern, which means one copy of the altered gene in each cell is sufficient to cause the disorder. There is also a non-hereditary form of cerebral amyloid angiopathy that occurs in people with no history of the disorder in their family. The cause of this form of the condition is unknown. These cases are described as sporadic and are not inherited.
Autosomal recessive hypotrichosis is a condition that affects hair growth. People with this condition have sparse hair (hypotrichosis) on the scalp beginning in infancy. This hair is usually coarse, dry, and tightly curled (often described as woolly hair). Scalp hair may also be lighter in color than expected and is fragile and easily broken. Affected individuals often cannot grow hair longer than a few inches. The eyebrows, eyelashes, and other body hair may be sparse as well. Over time, the hair problems can remain stable or progress to complete scalp hair loss (alopecia) and a decrease in body hair. Rarely, people with autosomal recessive hypotrichosis have skin problems affecting areas with sparse hair, such as redness (erythema), itchiness (pruritus), or missing patches of skin (erosions) on the scalp. In areas of poor hair growth, they may also develop bumps called hyperkeratotic follicular papules that develop around hair follicles, which are specialized structures in the skin where hair growth occurs.
Benign chronic pemphigus is a rare condition; its prevalence is unknown.
Mutations in the GLB1 gene cause GM1 gangliosidosis. The GLB1 gene provides instructions for making an enzyme called beta-galactosidase (-galactosidase), which plays a critical role in the brain. This enzyme is located in lysosomes, which are compartments within cells that break down and recycle different types of molecules. Within lysosomes, -galactosidase helps break down several molecules, including a substance called GM1 ganglioside. GM1 ganglioside is important for normal functioning of nerve cells in the brain. Mutations in the GLB1 gene reduce or eliminate the activity of -galactosidase. Without enough functional -galactosidase, GM1 ganglioside cannot be broken down when it is no longer needed. As a result, this substance accumulates to toxic levels in many tissues and organs, particularly in the brain. Progressive damage caused by the buildup of GM1 ganglioside leads to the destruction of nerve cells in the brain, causing many of the signs and symptoms of GM1 gangliosidosis. In general, the severity of GM1 gangliosidosis is related to the level of -galactosidase activity. Individuals with higher enzyme activity levels usually have milder signs and symptoms than those with lower activity levels because they have less accumulation of GM1 ganglioside within the body. Conditions such as GM1 gangliosidosis that cause molecules to build up inside the lysosomes are called lysosomal storage disorders.

What causes GM1 gangliosidosis? All three types of GM1 gangliosidosis are caused by mutations (changes) in the GLB1 gene. This gene gives the body instructions to make an enzyme called beta-galactosidase (-galactosidase), which plays an important role in the brain. The enzyme resides in compartments within cells called lysosomes, where it helps break down certain molecules, including a substance called GM1 ganglioside. GM1 ganglioside is important for nerve cell function in the brain. Mutations in the GLB1 gene may lower or eliminate the activity of the -galactosidase enzyme, keeping GM1 ganglioside from being broken down. As a result, it accumulates to toxic levels in tissues and organs, particularly in the brain. This accumulation leads to the destruction of nerve cells, causing the features of the condition. In general, people with higher enzyme activity levels usually have milder features than those with lower activity levels.
How might cryptogenic organizing pneumonia be treated? The treatment of cryptogenic organizing pneumonia (COP) generally depends on the severity of the condition. For example, people who are mildly affected may simply be monitored as some cases can improve on their own. Unfortunately, the majority of people with COP have persistent and/or progressive symptoms that will require therapy. In these cases, oral or intravenous glucocorticoids can be given which often result in rapid improvement of symptoms.
Autoimmune hemolytic anemia (AIHA) occurs when your immune system makes antibodies that attack your red blood cells. This causes a drop in the number of red blood cells, leading to hemolytic anemia. Symptoms may include unusual weakness and fatigue with tachycardia and breathing difficulties, jaundice, dark urine and/or splenomegaly. AIHA can be primary (idiopathic) or result from an underlying disease or medication. The condition may develop gradually or occur suddenly. There are two main types of autoimmune hemolytic anemia: warm antibody hemolytic anemia and cold antibody hemolytic anemia. Treatment may include corticosteroids such as prednisone, splenectomy, immunosuppressive drugs and/or blood transfusions.
Alpers-Huttenlocher syndrome is caused by mutations in the POLG gene. This gene provides instructions for making one part, the alpha subunit, of a protein called polymerase gamma (pol ). Pol functions in mitochondria, which are structures within cells that use oxygen to convert the energy from food into a form cells can use. Mitochondria each contain a small amount of DNA, known as mitochondrial DNA (mtDNA), which is essential for the normal function of these structures. Pol "reads" sequences of mtDNA and uses them as templates to produce new copies of mtDNA in a process called DNA replication. Most POLG gene mutations change single protein building blocks (amino acids) in the alpha subunit of pol . These changes result in a mutated pol that has a reduced ability to replicate DNA. Although the mechanism is unknown, mutations in the POLG gene often result in a reduced number of copies of mtDNA (mtDNA depletion), particularly in muscle, brain, and liver cells. MtDNA depletion causes a decrease in cellular energy, which could account for the signs and symptoms of Alpers-Huttenlocher syndrome. A mutation in the POLG gene has not been identified in approximately 13 percent of people diagnosed with Alpers-Huttenlocher syndrome. Researchers are working to identify other genes that may be responsible for the condition.
