Question: What causes Wolfram syndrome ?

Answer: What causes Wolfram syndrome? There are two types of Wolfram syndrome (type 1 and type 2) which are primarily differentiated by their genetic cause. Changes (mutations) in the WFS1 gene are responsible for approximately 90% of Wolfram syndrome type 1 cases. This gene encodes wolframin, a protein that is important for the proper functioning of the endoplasmic reticulum (the part of a cell that is involved in protein production, processing, and transport). Wolframin helps regulate the amount of calcium in cells, which is important for many different cellular functions. Mutations in WFS1 result in a defective form of wolframin that is unable to perform its normal role. This causes cells to trigger their own death (apoptosis). The death of cells in various organs and other parts of the body results in the signs and symptoms of Wolfram syndrome type 1. A specific mutation in the CISD2 gene causes Wolfram syndrome type 2. Although the exact function of this gene is not known, scientists suspect that it plays an important role in the mitochondria (the part of the cell where energy is produced). Mutations in CISD2 lead to the loss of mitochondria which decreases the amount of energy available to cells. Cells that do not have enough energy die. As in Wolfram syndrome type 1, the death of cells in different parts of the body results in the many health problems associated with Wolfram syndrome type 2. Mutations in mitochondrial DNA may also be a rare cause of Wolfram syndrome in some families.
Question: What is (are) Pigment-dispersion syndrome ?

Answer: Pigment-dispersion syndrome is an eye disorder that occurs when pigment granules that normally adhere to the back of the iris (the colored part of the eye) flake off into the clear fluid produced by the eye (aqueous humor). These pigment granules may flow towards the drainage canals of the eye, slowly clogging them and raising the pressure within the eye (intraocular pressure or IOP). This rise in eye pressure can cause damage to the optic nerve (the nerve in the back of the eye that carries visual images to the brain). If the optic nerve becomes damaged, pigment-dispersion syndrome becomes pigmentary glaucoma. This happens in about 30% of cases. Pigment-dispersion syndrome commonly presents between the second and fourth decades, which is earlier than other types of glaucoma. While men and women are affected in equal numbers, men develop pigmentary glaucoma up to 3 times more often than women. Myopia (nearsightedness) appears to be an important risk factor in the development of pigment-dispersion syndrome and is present in up to 80% of affected individuals. The condition may be sporadic or follow an autosomal dominant pattern of inheritance with reduced penetrance . At least one gene locus on chromosome 7 has been identified. Pigment-dispersion syndrome can be treated with eye drops or other medications. In some cases, laser surgery may be performed.

Question: What is (are) Paresthesia ?

Answer: Paresthesia refers to a burning or prickling sensation that is usually felt in the hands, arms, legs, or feet, but can also occur in other parts of the body. The sensation, which happens without warning, is usually painless and described as tingling or numbness, skin crawling, or itching.  Most people have experienced temporary paresthesia -- a feeling of "pins and needles" -- at some time in their lives when they have sat with legs crossed for too long, or fallen asleep with an arm crooked under their head. It happens when sustained pressure is placed on a nerve. The feeling quickly goes away once the pressure is relieved.  Chronic paresthesia is often a symptom of an underlying neurological disease or traumatic nerve damage. Paresthesia can be caused by disorders affecting the central nervous system, such as stroke and transient ischemic attacks (mini-strokes), multiple sclerosis, transverse myelitis, and encephalitis. A tumor or vascular lesion pressed up against the brain or spinal cord can also cause paresthesia. Nerve entrapment syndromes, such as carpal tunnel syndrome, can damage peripheral nerves and cause paresthesia accompanied by pain. Diagnostic evaluation is based on determining the underlying condition causing the paresthetic sensations. An individual's medical history, physical examination, and laboratory tests are essential for the diagnosis. Physicians may order additional tests depending on the suspected cause of the paresthesia.
Question: What is (are) Motor Neuron Diseases ?

Answer: The motor neuron diseases (MNDs) are a group of progressive neurological disorders that destroy cells that control essential muscle activity such as speaking, walking, breathing, and swallowing. Normally, messages from nerve cells in the brain (called upper motor neurons) are transmitted to nerve cells in the brain stem and spinal cord (called lower motor neurons) and from them to particular muscles. When there are disruptions in these signals, the result can be gradual muscle weakening, wasting away, and uncontrollable twitching (called fasciculations). Eventually, the ability to control voluntary movement can be lost. MNDs may be inherited or acquired, and they occur in all age groups. MNDs occur more commonly in men than in women, and symptoms may appear after age 40. In children, particularly in inherited or familial forms of the disease, symptoms can be present at birth or appear before the child learns to walk.
                
The causes of sporadic (noninherited) MNDs are not known, but environmental, toxic, viral, or genetic factors may be implicated. Common MNDs include amyotrophic lateral sclerosis (ALS), progressive bulbar palsy, primary lateral sclerosis, and progressive muscular atrophy. Other MNDs include the many inherited forms of spinal muscular atrophy and post-polio syndrome, a condition that can strike polio survivors decades after their recovery from poliomyelitis.
Question: What are the treatments for Motor Neuron Diseases ?

Answer: There is no cure or standard treatment for the MNDs. Symptomatic and supportive treatment can help patients be more comfortable while maintaining their quality of life. The drug riluzole (Rilutek), which as of this date is the only drug approved by the U.S. Food and Drug Administration to treat ALS, prolongs life by 2-3 months but does not relieve symptoms. Other medicines that may help reduce symptoms include muscle relaxants such as baclofen, tizanidine, and the benzodiazepines for spasticity; glycopyrrolate and atropine to treat excessive saliva; and anticonvulsants and nonsteroidal anti-inflammatory drugs to relieve pain. Panic attacks can be treated with benzodiazepines. Some patients may require stronger medicines such as morphine to cope with musculoskeletal abnormalities or pain in later stages of the disorders, and opiates are used to provide comfort care in terminal stages of the disease.
                
Physical and speech therapy, occupational therapy, and rehabilitation may help to improve posture, prevent joint immobility, slow muscle weakness and atrophy, and cope with swallowing difficulties. Applying heat may relieve muscle pain. Assistive devices such as supports or braces, orthotics, speech synthesizers, and wheelchairs help some patients retain independence. Proper nutrition and a balanced diet are essential to maintaining weight and strength.
Question: What are the genetic changes related to hyperprolinemia ?

Answer: Mutations in the ALDH4A1 and PRODH genes cause hyperprolinemia.  Inherited hyperprolinemia is caused by deficiencies in the enzymes that break down (degrade) proline. Hyperprolinemia type I is caused by a mutation in the PRODH gene, which provides instructions for producing the enzyme proline oxidase. This enzyme begins the process of degrading proline by starting the reaction that converts it to pyrroline-5-carboxylate.  Hyperprolinemia type II is caused by a mutation in the ALDH4A1 gene, which provides instructions for producing the enzyme pyrroline-5-carboxylate dehydrogenase. This enzyme helps to break down the pyrroline-5-carboxylate produced in the previous reaction, converting it to the amino acid glutamate. The conversion between proline and glutamate, and the reverse reaction controlled by different enzymes, are important in maintaining a supply of the amino acids needed for protein production, and for energy transfer within the cell.  A deficiency of either proline oxidase or pyrroline-5-carboxylate dehydrogenase results in a buildup of proline in the body. A deficiency of the latter enzyme leads to higher levels of proline and a buildup of the intermediate breakdown product pyrroline-5-carboxylate, causing the signs and symptoms of hyperprolinemia type II.
Question: What is (are) 3-hydroxy-3-methylglutaryl-CoA lyase deficiency ?

Answer: 3-hydroxy-3-methylglutaryl-CoA lyase deficiency (also known as HMG-CoA lyase deficiency) is an uncommon inherited disorder in which the body cannot process a particular protein building block (amino acid) called leucine. Additionally, the disorder prevents the body from making ketones, which are used for energy during periods without food (fasting).  The signs and symptoms of HMG-CoA lyase deficiency usually appear within the first year of life. The condition causes episodes of vomiting, diarrhea, dehydration, extreme tiredness (lethargy), and weak muscle tone (hypotonia). During an episode, blood sugar levels can become dangerously low (hypoglycemia), and a buildup of harmful compounds can cause the blood to become too acidic (metabolic acidosis). If untreated, the disorder can lead to breathing problems, convulsions, coma, and death. Episodes are often triggered by an infection, fasting, strenuous exercise, or other types of stress.  HMG-CoA lyase deficiency is sometimes mistaken for Reye syndrome, a severe disorder that develops in children while they appear to be recovering from viral infections such as chicken pox or flu. Most cases of Reye syndrome are associated with the use of aspirin during these viral infections.
Question: What is (are) Kufs disease ?

Answer: Kufs disease is a condition that primarily affects the nervous system, causing problems with movement and intellectual function that worsen over time. The signs and symptoms of Kufs disease typically appear around age 30, but they can develop anytime between adolescence and late adulthood.  Two types of Kufs disease have been described: type A and type B. The two types are differentiated by their genetic cause, pattern of inheritance, and certain signs and symptoms. Type A is characterized by a combination of seizures and uncontrollable muscle jerks (myoclonic epilepsy), a decline in intellectual function (dementia), impaired muscle coordination (ataxia), involuntary movements such as tremors or tics, and speech difficulties (dysarthria). Kufs disease type B shares many features with type A, but it is distinguished by changes in personality and is not associated with myoclonic epilepsy or dysarthria.  The signs and symptoms of Kufs disease worsen over time, and affected individuals usually survive about 15 years after the disorder begins.  Kufs disease is one of a group of disorders known as neuronal ceroid lipofuscinoses (NCLs), which are also known as Batten disease. These disorders affect the nervous system and typically cause progressive problems with vision, movement, and thinking ability. Kufs disease, however, does not affect vision. The different types of NCLs are distinguished by the age at which signs and symptoms first appear.
Question: What are the genetic changes related to trimethylaminuria ?

Answer: Mutations in the FMO3 gene cause trimethylaminuria. This gene provides instructions for making an enzyme that breaks down nitrogen-containing compounds from the diet, including trimethylamine. This compound is produced by bacteria in the intestine during the digestion of proteins from eggs, liver, legumes (such as soybeans and peas), certain kinds of fish, and other foods. Normally, the FMO3 enzyme converts strong-smelling trimethylamine into another molecule that has no odor. If the enzyme is missing or its activity is reduced because of a mutation in the FMO3 gene, trimethylamine is not processed properly and can build up in the body. As excess trimethylamine is released in a person's sweat, urine, and breath, it causes the odor characteristic of trimethylaminuria. Researchers believe that stress and diet also play a role in triggering symptoms.  Although FMO3 gene mutations account for most cases of trimethylaminuria, the condition can also be caused by other factors. The strong body odor may result from an excess of certain proteins in the diet or from an abnormal increase in bacteria that produce trimethylamine in the digestive system. A few cases of the disorder have been identified in adults with liver or kidney disease. Temporary symptoms of this condition have been reported in a small number of premature infants and in some healthy women at the start of menstruation.
Question: What is (are) Diabetes Type 2 ?

Answer: Diabetes means your blood glucose, or blood sugar, levels are too high. With type 2 diabetes, the more common type, your body does not make or use insulin well. Insulin is a hormone that helps glucose get into your cells to give them energy. Without insulin, too much glucose stays in your blood. Over time, high blood glucose can lead to serious problems with your heart, eyes, kidneys, nerves, and gums and teeth.    You have a higher risk of type 2 diabetes if you are older, obese, have a family history of diabetes, or do not exercise. Having prediabetes also increases your risk. Prediabetes means that your blood sugar is higher than normal but not high enough to be called diabetes.    The symptoms of type 2 diabetes appear slowly. Some people do not notice symptoms at all. The symptoms can include       - Being very thirsty    - Urinating often    - Feeling very hungry or tired    - Losing weight without trying    - Having sores that heal slowly    - Having blurry eyesight       Blood tests can show if you have diabetes. One type of test, the A1C, can also check on how you are managing your diabetes. Many people can manage their diabetes through healthy eating, physical activity, and blood glucose testing. Some people also need to take diabetes medicines.    NIH: National Institute of Diabetes and Digestive and Kidney Diseases
Question: What is (are) Pinworms ?

Answer: Pinworms are small parasites that can live in the colon and rectum. You get them when you swallow their eggs. The eggs hatch inside your intestines. While you sleep, the female pinworms leave the intestines through the anus and lay eggs on nearby skin.    Pinworms spread easily. When people who are infected touch their anus, the eggs attach to their fingertips. They can spread the eggs to others directly through their hands, or through contaminated clothing, bedding, food, or other articles. The eggs can live on household surfaces for up to 2 weeks.    The infection is more common in children. Many people have no symptoms at all. Some people feel itching around the anus or vagina. The itching may become intense, interfere with sleep, and make you irritable.    Your health care provider can diagnose pinworm infection by finding the eggs. A common way to collect the eggs is with a sticky piece of clear tape. Mild infections may not need treatment. If you do need medicine, everyone in the household should take it.     To prevent becoming infected or reinfected with pinworms,       - Bathe after waking up    - Wash your pajamas and bed sheets often    - Wash your hands regularly, especially after using the bathroom or changing diapers    - Change your underwear every day    - Avoid nail biting    - Avoid scratching the anal area       NIH: National Institute of Allergy and Infectious Diseases
