[User] What is (are) capillary malformation-arteriovenous malformation syndrome ?

[Assistant] Capillary malformation-arteriovenous malformation syndrome (CM-AVM) is a disorder of the vascular system, which is the body's complex network of blood vessels. The vascular system consists of arteries, which carry oxygen-rich blood from the heart to the body's various organs and tissues; veins, which carry blood back to the heart; and capillaries, which are tiny blood vessels that connect arteries and veins.  CM-AVM is characterized by capillary malformations (CMs), which are composed of enlarged capillaries that increase blood flow near the surface of the skin. These malformations look like multiple small, round, pink or red spots on the skin. In most affected individuals, capillary malformations occur on the face, arms, and legs. These spots may be visible from birth or may develop during childhood. By themselves, capillary malformations usually do not cause any health problems.  In some people with CM-AVM, capillary malformations are the only sign of the disorder. However, other affected individuals also have more serious vascular abnormalities known as arteriovenous malformations (AVMs) and arteriovenous fistulas (AVFs). AVMs and AVFs are abnormal connections between arteries, veins, and capillaries that affect blood circulation. Depending on where they occur in the body, these abnormalities can be associated with complications including abnormal bleeding, migraine headaches, seizures, and heart failure. In some cases the complications can be life-threatening. In people with CM-AVM, complications of AVMs and AVFs tend to appear in infancy or early childhood; however, some of these vascular abnormalities never cause any symptoms.  Some vascular abnormalities seen in CM-AVM are similar to those that occur in a condition called Parkes Weber syndrome. In addition to vascular abnormalities, Parkes Weber syndrome usually involves overgrowth of one limb. CM-AVM and some cases of Parkes Weber syndrome have the same genetic cause.

[User] What are the genetic changes related to X-linked thrombocytopenia ?

[Assistant] Mutations in the WAS gene cause X-linked thrombocytopenia. The WAS gene provides instructions for making a protein called WASP. This protein is found in all blood cells. WASP is involved in relaying signals from the surface of blood cells to the actin cytoskeleton, which is a network of fibers that make up the cell's structural framework. WASP signaling activates the cell when it is needed and triggers its movement and attachment to other cells and tissues (adhesion). In white blood cells, which protect the body from infection, this signaling allows the actin cytoskeleton to establish the interaction between cells and the foreign invaders that they target (immune synapse).  WAS gene mutations that cause X-linked thrombocytopenia typically lead to the production of an altered protein. The altered WASP has reduced function and cannot efficiently relay signals from the cell membrane to the actin cytoskeleton. In people with X-linked thrombocytopenia, these signaling problems primarily affect platelets, impairing their development. In some cases, white blood cells are affected. When WASP function is impaired in white blood cells, they are less able to respond to foreign invaders and immune problems such as infections, eczema, and autoimmune disorders can occur.

[User] What are the genetic changes related to juvenile idiopathic arthritis ?

[Assistant] Juvenile idiopathic arthritis is thought to arise from a combination of genetic and environmental factors. The term "idiopathic" indicates that the specific cause of the disorder is unknown. Its signs and symptoms result from excessive inflammation in and around the joints. Inflammation occurs when the immune system sends signaling molecules and white blood cells to a site of injury or disease to fight microbial invaders and facilitate tissue repair. Normally, the body stops the inflammatory response after healing is complete to prevent damage to its own cells and tissues. In people with juvenile idiopathic arthritis, the inflammatory response is prolonged, particularly during movement of the joints. The reasons for this excessive inflammatory response are unclear.  Researchers have identified changes in several genes that may influence the risk of developing juvenile idiopathic arthritis. Many of these genes belong to a family of genes that provide instructions for making a group of related proteins called the human leukocyte antigen (HLA) complex. The HLA complex helps the immune system distinguish the body's own proteins from proteins made by foreign invaders (such as viruses and bacteria). Each HLA gene has many different normal variations, allowing each person's immune system to react to a wide range of foreign proteins. Certain normal variations of several HLA genes seem to affect the risk of developing juvenile idiopathic arthritis, and the specific type of the condition that a person may have.  Normal variations in several other genes have also been associated with juvenile idiopathic arthritis. Many of these genes are thought to play roles in immune system function. Additional unknown genetic influences and environmental factors, such as infection and other issues that affect immune health, are also likely to influence a person's chances of developing this complex disorder.

[User] What causes Hereditary fructose intolerance ?

[Assistant] What causes hereditary fructose intolerance (HFI)? HFI is caused by alterations (mutations) in the ALDOB gene. This gene provides instructions for making an enzyme called aldolase B. This enzyme is primarily found in the liver and is involved in the breakdown of fructose into energy. Mutations in the ALDOB gene reduce the function of the enzyme, impairing its ability to metabolize fructose. This causes a toxic buildup of fructose-1-phosphate in liver cells, which results in the death of liver cells over time.

[User] Is Congenital adrenal hyperplasia inherited ?

[Assistant] How is congenital adrenal hyperplasia inherited? All forms of congenital adrenal hyperplasia (CAH) are inherited in an autosomal recessive manner. This means that to be affected, a person must have a mutation in both copies of the responsible gene in each cell. The parents of an affected person usually each carry one mutated copy of the gene and are referred to as carriers. Carriers typically do not show signs or symptoms of the condition. When two carriers of an autosomal recessive condition have children, each child has a 25% (1 in 4) risk to have the condition, a 50% (1 in 2) risk to be a carrier like each of the parents, and a 25% chance to not have the condition and not be a carrier.

[User] What to do for High Blood Pressure and Kidney Disease ?

[Assistant]
Following a healthy eating plan can help lower blood pressure. A health care provider may recommend the Dietary Approaches to Stop Hypertension (DASH) eating plan. DASH focuses on fruits, vegetables, whole grains, and other foods that are heart healthy and lower in sodium, which often comes from salt. The DASH eating plan

- is low in fat and cholesterol  - features fat-free or low-fat milk and dairy products, fish, poultry, and nuts  - suggests less red meat, sweets, added sugars, and sugar-containing beverages  - is rich in nutrients, protein, and fiber

Read more about DASH at www.nhlbi.nih.gov/health/resources/heart/hbp-dash-index.htm.

A dietitian may also recommend this type of diet for people who have already developed kidney disease. A diet low in sodium and liquid intake can help reduce edema and lower blood pressure. Reducing saturated fat and cholesterol can help control high levels of lipids, or fats, in the blood.

Health care providers may recommend that people with kidney disease eat moderate or reduced amounts of protein, though the benefits of reducing protein in a persons diet is still being researched. 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 who are on a restricted protein diet should be monitored with blood tests that can show low nutrient levels.

In addition, consuming too much alcohol raises blood pressure, so people should limit alcoholic drinkstwo per day for men and one per day for women.

A health care provider can help people change their diet to meet their individual needs.

Physical Activity

Regular physical activity can lower blood pressure and reduce the chances of other health problems. A health care provider can provide information about how much and what kinds of activity are safe. Most people should try to get at least 30 to 60 minutes of activity most or all days of the week. A person can do all physical activity at once or break up activities into shorter periods of at least 10 minutes each. Moderate activities include brisk walking, dancing, bowling, riding a bike, working in a garden, and cleaning the house.

Body Weight

People who are overweight or obese should aim to reduce their weight by 7 to 10 percent during the first year of treatment for high blood pressure. This amount of weight loss can lower the chance of health problems related to high blood pressure. Overweight is defined as a body mass index (BMI)a measurement of weight in relation to heightof 25 to 29. A BMI of 30 or higher is considered obese. A BMI lower than 25 is the goal for keeping blood pressure under control.5

Smoking

People who smoke should quit. Smoking can damage blood vessels, raise the chance of high blood pressure, and worsen health problems related to high blood pressure. People with high blood pressure should talk with their health care provider about programs and products they can use to quit smoking.

Stress

Learning how to manage stress, relax, and cope with problems can improve emotional and physical health. Some activities that may help reduce stress include

- exercising  - practicing yoga or tai chi  - listening to music  - focusing on something calm or peaceful  - meditating

[User] What is (are) MPV17-related hepatocerebral mitochondrial DNA depletion syndrome ?

[Assistant] MPV17-related hepatocerebral mitochondrial DNA depletion syndrome is an inherited disorder that can cause liver disease and neurological problems. The signs and symptoms of this condition begin in infancy and typically include vomiting, diarrhea, and an inability to grow or gain weight at the expected rate (failure to thrive). Many affected infants have a buildup of a chemical called lactic acid in the body (lactic acidosis) and low blood sugar (hypoglycemia). Within the first weeks of life, infants develop liver disease that quickly progresses to liver failure. The liver is frequently enlarged (hepatomegaly) and liver cells often have a reduced ability to release a digestive fluid called bile (cholestasis). Rarely, affected children develop liver cancer. After the onset of liver disease, many affected infants develop neurological problems, which can include developmental delay, weak muscle tone (hypotonia), and reduced sensation in the limbs (peripheral neuropathy). Individuals with MPV17-related hepatocerebral mitochondrial DNA depletion syndrome typically survive only into infancy or early childhood.  MPV17-related hepatocerebral mitochondrial DNA depletion syndrome is most frequently seen in the Navajo population of the southwestern United States. In this population, the condition is known as Navajo neurohepatopathy. People with Navajo neurohepatopathy tend to have a longer life expectancy than those with MPV17-related hepatocerebral mitochondrial DNA depletion syndrome. In addition to the signs and symptoms described above, people with Navajo neurohepatopathy may have problems with sensing pain that can lead to painless bone fractures and self-mutilation of the fingers or toes. Individuals with Navajo neurohepatopathy may lack feeling in the clear front covering of the eye (corneal anesthesia), which can lead to open sores and scarring on the cornea, resulting in impaired vision. The cause of these additional features is unknown.

[User] What is (are) multiple endocrine neoplasia ?

[Assistant] Multiple endocrine neoplasia is a group of disorders that affect the body's network of hormone-producing glands (the endocrine system). Hormones are chemical messengers that travel through the bloodstream and regulate the function of cells and tissues throughout the body. Multiple endocrine neoplasia typically involves tumors (neoplasia) in at least two endocrine glands; tumors can also develop in other organs and tissues. These growths can be noncancerous (benign) or cancerous (malignant). If the tumors become cancerous, the condition can be life-threatening.  The major forms of multiple endocrine neoplasia are called type 1, type 2, and type 4. These types are distinguished by the genes involved, the types of hormones made, and the characteristic signs and symptoms.  Many different types of tumors are associated with multiple endocrine neoplasia. Type 1 frequently involves tumors of the parathyroid glands, the pituitary gland, and the pancreas. Tumors in these glands can lead to the overproduction of hormones. The most common sign of multiple endocrine neoplasia type 1 is overactivity of the parathyroid glands (hyperparathyroidism). Hyperparathyroidism disrupts the normal balance of calcium in the blood, which can lead to kidney stones, thinning of bones, nausea and vomiting, high blood pressure (hypertension), weakness, and fatigue.  The most common sign of multiple endocrine neoplasia type 2 is a form of thyroid cancer called medullary thyroid carcinoma. Some people with this disorder also develop a pheochromocytoma, which is an adrenal gland tumor that can cause dangerously high blood pressure. Multiple endocrine neoplasia type 2 is divided into three subtypes: type 2A, type 2B (formerly called type 3), and familial medullary thyroid carcinoma (FMTC). These subtypes differ in their characteristic signs and symptoms and risk of specific tumors; for example, hyperparathyroidism occurs only in type 2A, and medullary thyroid carcinoma is the only feature of FMTC. The signs and symptoms of multiple endocrine neoplasia type 2 are relatively consistent within any one family.  Multiple endocrine neoplasia type 4 appears to have signs and symptoms similar to those of type 1, although it is caused by mutations in a different gene. Hyperparathyroidism is the most common feature, followed by tumors of the pituitary gland, additional endocrine glands, and other organs.

[User] What is (are) Gout ?

[Assistant] Gout is a common, painful form of arthritis. It causes swollen, red, hot and stiff joints.    Gout happens when uric acid builds up in your body. Uric acid comes from the breakdown of substances called purines. Purines are in your body's tissues and in foods, such as liver, dried beans and peas, and anchovies. Normally, uric acid dissolves in the blood. It passes through the kidneys and out of the body in urine. But sometimes uric acid can build up and form needle-like crystals. When they form in your joints, it is very painful. The crystals can also cause kidney stones.    Often, gout first attacks your big toe. It can also attack ankles, heels, knees, wrists, fingers, and elbows. At first, gout attacks usually get better in days. Eventually, attacks last longer and happen more often.    You are more likely to get gout if you       - Are a man    - Have family member with gout    - Are overweight    - Drink alcohol    - Eat too many foods rich in purines       Gout can be hard to diagnose. Your doctor may take a sample of fluid from an inflamed joint to look for crystals. You can treat gout with medicines.    Pseudogout has similar symptoms and is sometimes confused with gout. However, it is caused by calcium phosphate, not uric acid.    NIH: National Institute of Arthritis and Musculoskeletal and Skin Diseases

[User] What is the outlook for Adult Central Nervous System Tumors ?

[Assistant] Certain factors affect prognosis (chance of recovery) and treatment options. The prognosis (chance of recovery) and treatment options for primary brain and spinal cord tumors depend on the following:         - The type and grade of the tumor.    -  Where the tumor is in the brain or spinal cord.    - Whether the tumor can be removed by surgery.    - Whether cancer cells remain after surgery.    - Whether there are certain changes in the chromosomes.    - Whether the cancer has just been diagnosed or has recurred (come back).    - The patient's general health.        The prognosis and treatment options for metastatic brain and spinal cord tumors depend on the following:         - Whether there are more than two tumors in the brain or spinal cord.    - Where the tumor is in the brain or spinal cord.    - How well the tumor responds to treatment.    - Whether the primary tumor continues to grow or spread.

[User] What is (are) Corticobasal Degeneration ?

[Assistant] Corticobasal degeneration is a progressive neurological disorder characterized by nerve cell loss and atrophy (shrinkage) of multiple areas of the brain including the cerebral cortex and the basal ganglia. Corticobasal degeneration progresses gradually. Initial symptoms, which typically begin at or around age 60, may first appear on one side of the body (unilateral), but eventually affect both sides as the disease progresses. Symptoms are similar to those found in Parkinson disease, such as poor coordination, akinesia (an absence of movements), rigidity (a resistance to imposed movement), disequilibrium (impaired balance); and limb dystonia (abnormal muscle postures). Other symptoms such as cognitive and visual-spatial impairments, apraxia (loss of the ability to make familiar, purposeful movements), hesitant and halting speech, myoclonus (muscular jerks), and dysphagia (difficulty swallowing) may also occur. An individual with corticobasal degeneration eventually becomes unable to walk.

[Assistant] The National Institute of Neurological Disorders and Stroke (NINDS) conducts TSC research in its laboratories at the National Institutes of Health (NIH) and also supports TSC research through grants to major medical institutions across the country. Scientists in one study are learning more about the genes that can cause TSC and the function of the proteins those genes produce. Another study focuses on two major brain disorders --autism and epilepsy -- that occur in children with TSC. Other scientists are trying to determine what causes skin tumors to develop in individuals with TSC and to find the molecular basis of these tumors. Scientists hope knowledge gained from their current research will improve the genetic test for TSC and lead to new avenues of treatment, methods of prevention, and, ultimately, a cure.

[User] What is (are) Atherosclerosis ?

[Assistant]
Espaol

Atherosclerosis is a disease in which plaque builds up inside your arteries. Arteries are blood vessels that carry oxygen-rich blood to your heart and other parts of your body.

Plaque is made up of fat, cholesterol, calcium, and other substances found in the blood. Over time, plaque hardens and narrows your arteries. This limits the flow of oxygen-rich blood to your organs and other parts of your body.

Atherosclerosis can lead to serious problems, including heart attack, stroke, or even death.

Atherosclerosis

Atherosclerosis-Related Diseases

Atherosclerosis can affect any artery in the body, including arteries in the heart, brain, arms, legs, pelvis, and kidneys. As a result, different diseases may develop based on which arteries are affected.

Coronary Heart Disease

Coronary heart disease (CHD), also called coronary artery disease, occurs when plaque builds up in the coronary arteries. These arteries supply oxygen-rich blood to your heart.

Plaque narrows the coronary arteries and reduces blood flow to your heart muscle. Plaque buildup also makes it more likely that blood clots will form in your arteries. Blood clots can partially or completely block blood flow.

If blood flow to your heart muscle is reduced or blocked, you may have angina (chest pain or discomfort) or a heart attack.

Plaque also can form in the heart's smallest arteries. This disease is called coronary microvascular disease (MVD). In coronary MVD, plaque doesn't cause blockages in the arteries as it does in CHD.

Carotid Artery Disease

Carotid (ka-ROT-id) artery disease occurs if plaque builds up in the arteries on each side of your neck (the carotid arteries). These arteries supply oxygen-rich blood to your brain. If blood flow to your brain is reduced or blocked, you may have a stroke.

Peripheral Artery Disease

Peripheral artery disease (P.A.D.) occurs if plaque builds up in the major arteries that supply oxygen-rich blood to your legs, arms, and pelvis.

If blood flow to these parts of your body is reduced or blocked, you may have numbness, pain, and, sometimes, dangerous infections.

Chronic Kidney Disease

Chronic kidney disease can occur if plaque builds up in the renal arteries. These arteries supply oxygen-rich blood to your kidneys.

Over time, chronic kidney disease causes a slow loss of kidney function. The main function of the kidneys is to remove waste and extra water from the body.

Overview

The cause of atherosclerosis isn't known. However, certain traits, conditions, or habits may raise your risk for the disease. These conditions are known as risk factors.

You can control some risk factors, such as lack of physical activity, smoking, and an unhealthy diet. Others you can't control, such as age and a family history of heart disease.

Some people who have atherosclerosis have no signs or symptoms. They may not be diagnosed until after a heart attack or stroke.

The main treatment for atherosclerosis is lifestyle changes. You also may need medicines and medical procedures. These treatments, along with ongoing medical care, can help you live a healthier life.

Outlook

Improved treatments have reduced the number of deaths from atherosclerosis-related diseases. These treatments also have improved the quality of life for people who have these diseases. However, atherosclerosis remains a common health problem.

You may be able to prevent or delay atherosclerosis and the diseases it can cause. Making lifestyle changes and getting ongoing care can help you avoid the problems of atherosclerosis and live a long, healthy life.

[User] How to diagnose Adrenal Insufficiency and Addison's Disease ?

[Assistant]
After Addisons disease is diagnosed, health care providers may use the following tests to look at the adrenal glands, find out whether the disease is related to TB, or identify antibodies associated with autoimmune Addisons disease.

- Ultrasound of the abdomen. Ultrasound uses a device, called a transducer, that bounces safe, painless sound waves off organs to create an image of their structure. A specially trained technician performs the procedure in a health care providers office, an outpatient center, or a hospital, and a radiologista doctor who specializes in medical imaginginterprets the images; a patient does not need anesthesia. The images can show abnormalities in the adrenal glands, such as enlargement or small size, nodules, or signs of calcium deposits, which may indicate bleeding.   - Tuberculin skin test. A tuberculin skin test measures how a patients immune system reacts to the bacteria that cause TB. A small needle is used to put some testing material, called tuberculin, under the skin. A nurse or lab technician performs the test in a health care providers office; a patient does not need anesthesia. In 2 to 3 days, the patient returns to the health care provider, who will check to see if the patient had a reaction to the test. The test can show if adrenal insufficiency could be related to TB.  To test whether a person has TB infection, which is when TB bacteria live in the body without making the person sick, a special TB blood test is used. To test whether a person has TB disease, which is when TB bacteria are actively attacking a persons lungs and making the person sick, other tests such as a chest x ray and a sample of sputumphlegm that is coughed up from deep in the lungsmay be needed.   - Antibody blood tests. A blood test involves drawing blood at a health care providers office or a commercial facility and sending the sample to a lab for analysis. The blood test can detect antibodiesproteins made by the immune system to protect the body from foreign substancesassociated with autoimmune Addisons disease.

After secondary adrenal insufficiency is diagnosed, health care providers may use the following tests to obtain a detailed view of the pituitary gland and assess how it is functioning:

- Computerized tomography (CT) scan. CT scans use a combination of x rays and computer technology to create images. For a CT scan, the patient may be given a solution to drink and an injection of a special dye, called contrast medium. CT scans require the patient to lie on a table that slides into a tunnel-shaped device where the x rays are taken. An x-ray technician performs the procedure in an outpatient center or a hospital, and a radiologist interprets the images. The patient does not need anesthesia. A CT scan can show size and shape of the pituitary gland to find out if an abnormality is present.   - Magnetic resonance imaging (MRI). MRI machines use radio waves and magnets to produce detailed pictures of the bodys internal organs and soft tissues without using x rays. An MRI may include the injection of contrast medium. With most MRI machines, the patient lies on a table that slides into a tunnel-shaped device that may be open ended or closed at one end; some machines are designed to allow the patient to lie in a more open space. A specially trained technician performs the procedure in an outpatient center or a hospital, and a radiologist interprets the images. The patient does not need anesthesia, though people with a fear of confined spaces may receive light sedation, taken by mouth. MRIs can be used to produce a three-dimensional (3-D) image of the hypothalamus and the pituitary gland to find out if an abnormality is present.   - Hormonal blood tests. Hormonal blood tests can assess how the pituitary gland is functioning and its ability to produce other hormones.

[User] What are the genetic changes related to 2-methylbutyryl-CoA dehydrogenase deficiency ?

[Assistant] Mutations in the ACADSB gene cause 2-methylbutyryl-CoA dehydrogenase deficiency.  The ACADSB gene provides instructions for making an enzyme called 2-methylbutyryl-CoA dehydrogenase that helps process the amino acid isoleucine. Mutations in the ACADSB gene reduce or eliminate the activity of this enzyme. With a shortage (deficiency) of 2-methylbutyryl-CoA dehydrogenase, the body is unable to break down isoleucine properly. As a result, isoleucine is not converted to energy, which can lead to characteristic features of this disorder, such as lethargy and muscle weakness. Also, an organic acid called 2-methylbutyrylglycine and related compounds may build up to harmful levels, causing serious health problems.

[User] What is (are) ataxia neuropathy spectrum ?

[Assistant] Ataxia neuropathy spectrum is part of a group of conditions called the POLG-related disorders. The conditions in this group feature a range of similar signs and symptoms involving muscle-, nerve-, and brain-related functions. Ataxia neuropathy spectrum now includes the conditions previously called mitochondrial recessive ataxia syndrome (MIRAS) and sensory ataxia neuropathy dysarthria and ophthalmoplegia (SANDO).  As the name implies, people with ataxia neuropathy spectrum typically have problems with coordination and balance (ataxia) and disturbances in nerve function (neuropathy). The neuropathy can be classified as sensory, motor, or a combination of the two (mixed). Sensory neuropathy causes numbness, tingling, or pain in the arms and legs, and motor neuropathy refers to disturbance in the nerves used for muscle movement.  Most people with ataxia neuropathy spectrum also have severe brain dysfunction (encephalopathy) and seizures. Some affected individuals have weakness of the external muscles of the eye (ophthalmoplegia), which leads to drooping eyelids (ptosis). Other signs and symptoms can include involuntary muscle twitches (myoclonus), liver disease, depression, migraine headaches, or blindness.

[User] What is (are) Citrullinemia type I ?

[Assistant] Citrullinemia type I is an inherited disorder that causes ammonia and other toxic substances to accumulate in the blood. This condition, also known as classic citrullinemia, belongs to a class of genetic diseases called urea cycle disorders. In most cases, the condition becomes evident in the first few days of life. Affected infants typically appear normal at birth, but as ammonia builds up in the body they experience a progressive lack of energy (lethargy), poor feeding, vomiting, seizures, and loss of consciousness. Citrullinemia type I is caused by mutations in the ASS1 gene. It is inherited in an autosomal recessive pattern.

[User] What are the treatments for Progeria ?

[Assistant] How might progeria be treated? Management for progeria generally focuses on the signs and symptoms of the condition and may include the following: Exercise, diet modification, and medication when the lipid profile becomes abnormal Frequent small meals to maximize caloric intake Oral hydration Use of shoe pads for foot discomfort due to lack of body fat Use of sunscreen on all exposed areas of skin Nitroglycerin for angina Routine anticongestive therapy if congestive heart failure is present Statins for their putative effect on farnesylation inhibition Anticoagulation therapy if vascular blockage, transient ischemic attacks, stroke, angina, or heart attack occur Routine physical and occupational therapy to help maintain range of motion in large and small joints Although there is currently no cure for progeria, research involving treatments is ongoing and scientists have been making much progress. The results of a recently published phase II clinical trial provided preliminary evidence that lonafarnib, a farnesyltransferase inhibitor, may improve cardiovascular status, bone structure, and audiological (hearing) status in affected children.

[User] What is (are) Myasthenia Gravis ?

[Assistant] Myasthenia gravis is a chronic autoimmune neuromuscular disease characterized by varying degrees of weakness of the skeletal (voluntary) muscles of the body. Symptoms vary in type and intensity. The hallmark of myasthenia gravis is muscle weakness that increases during periods of activity and improves after periods of rest. Muscles that control eye and eyelid movements, facial expression, chewing, talking, and swallowing are often, but not always, involved. The muscles that control breathing and neck and limb movements may also be affected. Myasthenia gravis is caused by a defect in the transmission of nerve impulses to muscles. Normally when impulses travel down the nerve, the nerve endings release a neurotransmitter substance called acetylcholine. In myasthenia gravis, antibodies produced by the body's own immune system block, alter, or destroy the receptors for acetylcholine. The first noticeable symptoms of myasthenia gravis may be weakness of the eye muscles, difficulty in swallowing, or slurred speech. Myasthenia gravis is an autoimmune disease because the immune system--which normally protects the body from foreign organisms--mistakenly attacks itself.. It is not directly inherited nor is it contagious.

[User] What is (are) hereditary hemorrhagic telangiectasia ?

[Assistant] Hereditary hemorrhagic telangiectasia is a disorder that results in the development of multiple abnormalities in the blood vessels.  In the circulatory system, blood carrying oxygen from the lungs is normally pumped by the heart into the arteries at high pressure. The pressure allows the blood to make its way through the arteries to the smaller vessels (arterioles and capillaries) that supply oxygen to the body's tissues. By the time blood reaches the capillaries, the pressure is much lower. The blood then proceeds from the capillaries into veins, through which it eventually returns to the heart.  In hereditary hemorrhagic telangiectasia, some arterial vessels flow directly into veins rather than into the capillaries. These abnormalities are called arteriovenous malformations. When they occur in vessels near the surface of the skin, where they are visible as red markings, they are known as telangiectases (the singular is telangiectasia).  Without the normal buffer of the capillaries, the blood moves from the arteries at high pressure into the thinner walled, less elastic veins. The extra pressure tends to strain and enlarge these blood vessels, and may result in compression or irritation of adjacent tissues and frequent episodes of severe bleeding (hemorrhage). Nosebleeds are very common in people with hereditary hemorrhagic telangiectasia, and more serious problems may arise from hemorrhages in the brain, liver, lungs, or other organs.  Forms of hereditary hemorrhagic telangiectasia include type 1, type 2, type 3, and juvenile polyposis/hereditary hemorrhagic telangiectasia syndrome. People with type 1 tend to develop symptoms earlier than those with type 2, and are more likely to have blood vessel malformations in the lungs and brain. Type 2 and type 3 may be associated with a higher risk of liver involvement. Women are more likely than men to develop blood vessel malformations in the lungs with type 1, and are also at higher risk of liver involvement with both type 1 and type 2. Individuals with any form of hereditary hemorrhagic telangiectasia, however, can have any of these problems.  Juvenile polyposis/hereditary hemorrhagic telangiectasia syndrome is a condition that involves both arteriovenous malformations and a tendency to develop growths (polyps) in the gastrointestinal tract. Types 1, 2 and 3 do not appear to increase the likelihood of such polyps.

[User] What causes Pleurisy and Other Pleural Disorders ?

[Assistant]
Pleurisy

Many conditions can cause pleurisy. Viral infections are likely the most common cause. Other causes of pleurisy include:

Bacterial infections, such as pneumonia (nu-MO-ne-ah) and tuberculosis, and infections from fungi or parasites

Pulmonary embolism, a blood clot that travels through the blood vessels to the lungs

Autoimmune disorders, such as lupus and rheumatoid arthritis

Cancer, such as lung cancer, lymphoma, and mesothelioma (MEZ-o-thee-lee-O-ma)

Chest and heart surgery, especially coronary artery bypass grafting

Lung diseases, such as LAM (lymphangioleiomyomatosis) or asbestosis (as-bes-TO-sis)

Inflammatory bowel disease

Familial Mediterranean fever, an inherited condition that often causes fever and swelling in the abdomen or lungs

Other causes of pleurisy include chest injuries, pancreatitis (an inflamed pancreas), and reactions to certain medicines. Reactions to certain medicines can cause a condition similar to lupus. These medicines include procainamide, hydralazine, and isoniazid.

Sometimes doctors can't find the cause of pleurisy.

Pneumothorax

Lung diseases or acute lung injury can make it more likely that you will develop a pneumothorax (a buildup of air or gas in the pleural space). Such lung diseases may include COPD (chronic obstructive pulmonary disease), tuberculosis, and LAM.

Surgery or a chest injury also may cause a pneumothorax.

You can develop a pneumothorax without having a recognized lung disease or chest injury. This is called a spontaneous pneumothorax. Smoking increases your risk of spontaneous pneumothorax. Having a family history of the condition also increases your risk.

Pleural Effusion

The most common cause of a pleural effusion (a buildup of fluid in the pleural space) is heart failure. Lung cancer, LAM, pneumonia, tuberculosis, and other lung infections also can lead to a pleural effusion.

Sometimes kidney or liver disease can cause fluid to build up in the pleural space. Asbestosis, sarcoidosis (sar-koy-DO-sis), and reactions to some medicines also can lead to a pleural effusion.

Hemothorax

An injury to the chest, chest or heart surgery, or lung or pleural cancer can cause a hemothorax (buildup of blood in the pleural space).

A hemothorax also can be a complication of an infection (for example, pneumonia), tuberculosis, or a spontaneous pneumothorax.

[User] What is the outlook for Male Breast Cancer ?

[Assistant]
Survival for men with breast cancer is similar to survival for women with breast cancer.
                    Survival for men with breast cancer is similar to that for women with breast cancer when their stage at diagnosis is the same. Breast cancer in men, however, is often diagnosed at a later stage. Cancer found at a later stage may be less likely to be cured.

                    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 (whether it is in the breast only or has spread to other places in the body).    - The type of breast cancer.    - Estrogen-receptor and progesterone-receptor levels in the tumor tissue.    - Whether the cancer is also found in the other breast.    - The patients age and general health.

[User] Is mitochondrial complex III deficiency inherited ?

[Assistant] Mitochondrial complex III deficiency is usually 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.  In some cases caused by mutations in the MT-CYB gene, the condition is not inherited; it is caused by new mutations in the gene that occur in people with no history of the condition in their family. Other cases caused by mutations in the MT-CYB gene are inherited in a mitochondrial pattern, which is also known as maternal inheritance. This pattern of inheritance applies to genes contained in mtDNA. Because egg cells, but not sperm cells, contribute mitochondria to the developing embryo, children can only inherit disorders resulting from mtDNA mutations from their mother. These disorders can appear in every generation of a family and can affect both males and females, but fathers do not pass traits associated with changes in mtDNA to their children.

[User] What is (are) Osteoporosis ?

[Assistant] Osteoporosis makes your bones weak and more likely to break. Anyone can develop osteoporosis, but it is common in older women. As many as half of all women and a quarter of men older than 50 will break a bone due to osteoporosis.    Risk factors include        -  Getting older     -  Being small and thin     -  Having a family history of osteoporosis    -  Taking certain medicines    -  Being a white or Asian woman    -  Having osteopenia, which is low bone density       Osteoporosis is a silent disease. You might not know you have it until you break a bone. A bone mineral density test is the best way to check your bone health. To keep bones strong, eat a diet rich in calcium and vitamin D, exercise and do not smoke. If needed, medicines can also help.

[User] What are the genetic changes related to autosomal dominant vitreoretinochoroidopathy ?

[Assistant] ADVIRC is caused by mutations in the BEST1 gene. The protein produced from this gene, called bestrophin-1, is thought to play a critical role in normal vision. Bestrophin-1 is found in a thin layer of cells at the back of the eye called the retinal pigment epithelium. This cell layer supports and nourishes the retina and is involved in growth and development of the eye, maintenance of the retina, and the normal function of specialized cells called photoreceptors that detect light and color. In the retinal pigment epithelium, bestrophin-1 functions as a channel that transports charged chlorine atoms (chloride ions) across the cell membrane.  Mutations in the BEST1 gene alter how the gene's instructions are used to make bestrophin-1, which leads to production of versions of the protein that are missing certain segments or have extra segments. It is not clear how these versions of bestrophin affect chloride ion transport or lead to the eye abnormalities characteristic of ADVIRC. Researchers suspect that the abnormalities are related to defects in the retinal pigment epithelium or the photoreceptors.

[User] What are the genetic changes related to Tietz syndrome ?

[Assistant] Tietz syndrome is caused by mutations in the MITF gene. This gene provides instructions for making a protein that plays a role in the development, survival, and function of certain types of cells. Molecules of the MITF protein attach (bind) to each other or with other proteins that have a similar structure, creating a two-protein unit (dimer). The dimer attaches to specific areas of DNA and helps control the activity of particular genes. On the basis of this action, the MITF protein is called a transcription factor.  The MITF protein helps control the development and function of pigment-producing cells called melanocytes. Within these cells, this protein controls production of the pigment melanin, which contributes to hair, eye, and skin color. Melanocytes are also found in the inner ear and play an important role in hearing. Additionally, the MITF protein regulates the development of the retinal pigment epithelium.  MITF gene mutations that cause Tietz syndrome either delete or change a single protein building block (amino acid) in an area of the MITF protein known as the basic motif region. Dimers incorporating the abnormal MITF protein cannot be transported into the cell nucleus to bind with DNA. As a result, most of the dimers are unavailable to bind to DNA, which affects the development of melanocytes and the production of melanin. The resulting reduction or absence of melanocytes in the inner ear leads to hearing loss. Decreased melanin production (hypopigmentation) accounts for the light skin and hair color and the retinal pigment epithelium changes that are characteristic of Tietz syndrome.  Researchers suggest that Tietz syndrome may represent a severe form of a disorder called Waardenburg syndrome, which can also be caused by MITF gene mutations.

[User] What are the genetic changes related to granulomatosis with polyangiitis ?

[Assistant] The genetic basis of GPA is not well understood. Having a particular version of the HLA-DPB1 gene is the strongest genetic risk factor for developing this condition, although several other genes, some of which have not been identified, may be involved. It is likely that a combination of genetic and environmental factors lead to GPA.  GPA is an autoimmune disorder. Such disorders occur when the immune system malfunctions and attacks the body's own tissues and organs. Approximately 90 percent of people with GPA have an abnormal immune protein called an anti-neutrophil cytoplasmic antibody (ANCA) in their blood. Antibodies normally bind to specific foreign particles and germs, marking them for destruction, but ANCAs attack normal human proteins. Most people with GPA have an ANCA that attacks the human protein proteinase 3 (PR3). A few affected individuals have an ANCA that attacks a protein called myeloperoxidase (MPO). When these antibodies attach to the protein they recognize, they trigger inflammation, which contributes to the signs and symptoms of GPA.  The HLA-DPB1 gene belongs to a family of genes called the human leukocyte antigen (HLA) complex. The HLA complex helps the immune system distinguish the body's own proteins from proteins made by foreign invaders (such as viruses and bacteria). Each HLA gene has many different normal variations, allowing each person's immune system to react to a wide range of foreign proteins. A particular variant of the HLA-DPB1 gene called HLA-DPB1*0401 has been found more frequently in people with GPA, especially those with ANCAs, than in people without the condition.  Because the HLA-DPB1 gene is involved in the immune system, changes in it might be related to the autoimmune response and inflammation in the respiratory tract and kidneys characteristic of GPA. However, it is unclear what specific role the HLA-DPB1*0401 gene variant plays in development of this condition.

[User] Is Cornelia de Lange syndrome inherited ?

[Assistant] Is Cornelia de Lange syndrome inherited? Cornelia de Lange syndrome (CdLS) can be inherited in an autosomal dominant (NIPBL, SMC2, or RAD21) or X-linked (SMC1A or HDAC8) manner depending on the underlying genetic cause. However, most cases (more than 99%) result from new (de novo) mutations and occur in people with no family history of the condition.

[User] What is (are) Asperger Syndrome ?

[Assistant]
Asperger syndrome (AS) is a developmental disorder. It is an autism spectrum disorder (ASD), one of a distinct group of neurological conditions characterized by a greater or lesser degree of impairment in language and communication skills, as well as repetitive or restrictive patterns of thought and behavior. Other ASDs include: classic autism, Rett syndrome, childhood disintegrative disorder, and pervasive developmental disorder not otherwise specified (usually referred to as PDD-NOS). Unlike children with autism, children with AS retain their early language skills.

The most distinguishing symptom of AS is a childs obsessive interest in a single object or topic to the exclusion of any other. Children with AS want to know everything about their topic of interest and their conversations with others will be about little else. Their expertise, high level of vocabulary, and formal speech patterns make them seem like little professors. Other characteristics of AS include repetitive routines or rituals; peculiarities in speech and language; socially and emotionally inappropriate behavior and the inability to interact successfully with peers; problems with non-verbal communication; and clumsy and uncoordinated motor movements.

Children with AS are isolated because of their poor social skills and narrow interests. They may approach other people, but make normal conversation impossible by inappropriate or eccentric behavior, or by wanting only to talk about their singular interest.Children with AS usually have a history of developmental delays in motor skills such as pedaling a bike, catching a ball, or climbing outdoor play equipment. They are often awkward and poorly coordinated with a walk that can appear either stilted or bouncy.

[User] What are the genetic changes related to Brody myopathy ?

[Assistant] Mutations in the ATP2A1 gene cause Brody myopathy. The ATP2A1 gene provides instructions for making an enzyme called sarco(endo)plasmic reticulum calcium-ATPase 1 (SERCA1). The SERCA1 enzyme is found in skeletal muscle cells, specifically in the membrane of a structure called the sarcoplasmic reticulum. This structure plays a major role in muscle contraction and relaxation by storing and releasing positively charged calcium atoms (calcium ions). When calcium ions are transported out of the sarcoplasmic reticulum, muscles contract; when calcium ions are transported into the sarcoplasmic reticulum, muscles relax. The SERCA1 enzyme transports calcium ions from the cell into the sarcoplasmic reticulum, triggering muscle relaxation.  ATP2A1 gene mutations lead to the production of a SERCA1 enzyme with decreased or no function. As a result, calcium ions are slow to enter the sarcoplasmic reticulum and muscle relaxation is delayed. After exercise or strenuous activity, during which the muscles rapidly contract and relax, people with Brody myopathy develop muscle cramps because their muscles cannot fully relax.

[User] What causes Varicose Veins ?

[Assistant]
Weak or damaged valves in the veins can cause varicose veins. After your arteries and capillaries deliver oxygen-rich blood to your body, your veins return the blood to your heart. The veins in your legs must work against gravity to do this.

One-way valves inside the veins open to let blood flow through, and then they shut to keep blood from flowing backward. If the valves are weak or damaged, blood can back up and pool in your veins. This causes the veins to swell.

Weak vein walls may cause weak valves. Normally, the walls of the veins are elastic (stretchy). If these walls become weak, they lose their normal elasticity. They become like an overstretched rubber band. This makes the walls of the veins longer and wider, and it causes the flaps of the valves to separate.

When the valve flaps separate, blood can flow backward through the valves. The backflow of blood fills the veins and stretches the walls even more. As a result, the veins get bigger, swell, and often twist as they try to squeeze into their normal space. These are varicose veins.

Normal Vein and Varicose Vein

Figure A shows a normal vein with a working valve and normal blood flow. Figure B shows a varicose vein with a deformed valve, abnormal blood flow, and thin, stretched walls. The middle image shows where varicose veins might appear in a leg.

Older age or a family history of varicose veins may raise your risk for weak vein walls. You also may be at higher risk if you have increased pressure in your veins due to overweight or obesity or pregnancy.

[User] What are the symptoms of Rotor syndrome ?

[Assistant] What are the signs and symptoms of Rotor syndrome? Jaundice, characterized by yellowing of the skin and/or whites of the eyes (conjunctival icterus), is usually the only symptom of Rotor syndrome. Jaundice usually begins shortly after birth or in childhood and may come and go. The Human Phenotype Ontology provides the following list of signs and symptoms for Rotor 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) Abnormality of the liver 90% Abdominal pain 7.5% Abnormality of temperature regulation 7.5% Abnormality of the gastric mucosa 7.5% Abnormality of skin pigmentation - Abnormality of the skeletal system - Autosomal recessive inheritance - Conjugated hyperbilirubinemia - Jaundice - 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.

[User] what research (or clinical trials) is being done for Nasopharyngeal Cancer ?

[Assistant]
New types of treatment are being tested in clinical trials.
                    Information about clinical trials is available from the NCI website.

                    Patients may want to think about taking part in a clinical trial.
                    For some patients, taking part in a clinical trial may be the best treatment choice. Clinical trials are part of the cancer research process. Clinical trials are done to find out if new cancer treatments are safe and effective or better than the standard treatment.   Many of today's standard treatments for cancer are based on earlier clinical trials. Patients who take part in a clinical trial may receive the standard treatment or be among the first to receive a new treatment.   Patients who take part in clinical trials also help improve the way cancer will be treated in the future. Even when clinical trials do not lead to effective new treatments, they often answer important questions and help move research forward.

                    Patients can enter clinical trials before, during, or after starting their cancer treatment.
                    Some clinical trials only include patients who have not yet received treatment. Other trials test treatments for patients whose cancer has not gotten better. There are also clinical trials that test new ways to stop cancer from recurring (coming back) or reduce the side effects of cancer treatment.   Clinical trials are taking place in many parts of the country. See the Treatment Options section that follows for links to current treatment clinical trials. These have been retrieved from NCI's listing of clinical trials.

[User] What is (are) congenital insensitivity to pain ?

[Assistant] Congenital insensitivity to pain is a condition that inhibits the ability to perceive physical pain. From birth, affected individuals never feel pain in any part of their body when injured. People with this condition can feel the difference between sharp and dull and hot and cold, but cannot sense, for example, that a hot beverage is burning their tongue. This lack of pain awareness often leads to an accumulation of wounds, bruises, broken bones, and other health issues that may go undetected. Young children with congenital insensitivity to pain may have mouth or finger wounds due to repeated self-biting and may also experience multiple burn-related injuries. These repeated injuries often lead to a reduced life expectancy in people with congenital insensitivity to pain. Many people with congenital insensitivity to pain also have a complete loss of the sense of smell (anosmia).  Congenital insensitivity to pain is considered a form of peripheral neuropathy because it affects the peripheral nervous system, which connects the brain and spinal cord to muscles and to cells that detect sensations such as touch, smell, and pain.

[User] What is (are) Pulmonary alveolar proteinosis acquired ?

[Assistant] Acquired pulmonary alveolar proteinosis (PAP) is a rare, acquired lung disorder characterized by the accumulation of grainy material consisting mostly of protein and fat (lipoproteinaceous material) in the air sacs of the lungs (alveoli). Most cases affect adults between the ages of 20-50. The symptoms can vary greatly; some individuals may not show symptoms, while others may experience progressive difficulty breathing and shortness of breath upon exertion. Other signs and symptoms may include a dry, chronic cough; fatigue; weight loss; chest pain; and a general feeling of ill health. In rare cases, the coughing up of blood, rounding and swelling of the tips of the fingers, and cyanosis may be present. Most cases occur for no known reason, but some cases may occur secondary to environmental exposures or underlying diseases; some researchers believe it may be an autoimmune disorder. The treatment varies from case to case depending upon the age of the affected individual and severity of the disease. Acquired PAP differs from congenital PAP, an extremely rare form of PAP that occurs in some newborns.

[User] What is (are) Lysinuric protein intolerance ?

[Assistant] Lysinuric protein intolerance is a metabolic disorder caused by the body's inability to digest and use the amino acids lysine, arginine, and ornithine. Because the body cannot effectively break down these amino acids, which are found in many protein-rich foods, individuals experience nausea and vomiting after ingesting protein. Other features associated with protein intolerance may also occur, including short stature, muscle weakness, impaired immune function, and osteoporosis. A lung disorder called pulmonary alveolar proteinosis may develop in some individuals, as can end-stage renal disease, coma and intellectual disability. Symptoms usually develop after infants are weaned and begin to eat solid foods. Lysinuric protein intolerance is caused by mutations in the SLC7A7 gene. It is inherited in an autosomal recessive manner.

[User] Is cyclic vomiting syndrome inherited ?

[Assistant] In most cases of cyclic vomiting syndrome, affected people have no known history of the disorder in their family. However, many affected individuals have a family history of related conditions, such as migraines, irritable bowel syndrome, or depression, in their mothers and other maternal relatives. This family history suggests an inheritance pattern known as maternal inheritance or mitochondrial inheritance, which applies to genes contained in mtDNA. Because egg cells, but not sperm cells, contribute mitochondria to the developing embryo, children can only inherit disorders resulting from mtDNA mutations from their mother. These disorders can appear in every generation of a family and can affect both males and females, but fathers do not pass traits associated with changes in mtDNA to their children.  Occasionally, people with cyclic vomiting syndrome have a family history of the disorder that does not follow maternal inheritance. In these cases, the inheritance pattern is unknown.
