How Much Of The Population Is Affected By Muscular Dystrophy
Muscular dystrophy includes a number of disorders which are associated primarily with abnormalities of the architecture of the cells, often causing changes in size and function (weakness). These disorders are typically inherited, and recognized early in life, although there are of course exceptions to this. Prognosis is based on the type of MD and expression ...Read more
Why is the glycosylation of dystroglycan important for its function as in the case with duchennes muscular dystrophy?
Muscle unstable: Dystrophin is an important components of the skeleton of the muscle fiber that helps keep the membrane stable and the membrane proteins "anchored" in the correct place in the cells that allows to perform their normal function. When this is absent such as in duchenne, the muscle fibers degenerate. The sarcoglycans are other components that are linked to dystrophin and have relatively similar role. ...Read more
It's progressive: The most common forms of muscular dystrophy are progressive. Immobility in general is related to muscle atrophy independent of disease. Patients with muscular dystrophy who stay active retain independence longer than those who do not, and some medications and surgeries can assist in this goal. ...Read moreSee 1 more doctor answer
Common: One boy in 3500 is born to develop duchenne's; it's uncommon in girls. Since the boys do not live as long as other people, around 1 child in 7000 has duchennes but it's much less common among adults. Becker's, the mild version, is about as common and most patients make it well into middle age. ...Read more
Muscular dystrophies: are a group of inherited neuromuscular disorders. Of the 9 major types & > 100 related disorders, each is caused by a specific mutant gene or genes. Some are inherited in an X-linked recessive pattern from a carrier mother; others are autosomal dominant, meaning each child of an affected parent has a 50% chance of inheriting it. Please specify the type to know the specific genetic defect. ...Read more
Striking differences: Muscular dystrophy usually starts in childhood or adolescence, less commonly later in life. It is a hereditary progressive condition, causing problems with weakness in skeletal muscles, and occasionally cardiac muscles, with abnormal muscle enzymes. MS is an inflammatory autoimmune condition, affecting brain, spinal cord, and eyes, with relapses and remissions. MRI lesions can confirm. ...Read moreSee 1 more doctor answer
What amount of intelligence is determined by genes and how much of it is determined by environment?
Genes vs environment: Too complex to answer here. No one really knows. ...Read more
Animal urine: You get leptospirosis from contact with the urine of animals, especially rodents. This may occur with the ingestion of contaminated water, food or soil. The disease starts with a fever, headache, and other flu-like symptoms. After recovering from those symptoms, you can then go on to develop meningitis, kidney failure, and liver damage with jaundice. ...Read more
It is neither: Common, nor hereditary. There seems to be damage to genes, as in most cancers, and some forecast response to therapy (loss of chromosome 1). The dread glioblastoma, the far end of the histologic spectrum, has had very little progress therapeutically. Despite its local resistance, chemo approachs encourage many, but surgery and radiotherapy seem stalled. ...Read more

Uncertain: Many researchers agree that genes may predispose some people to excess weight gain, although the exact relationship between genetics & obesity is unclear. Other inherited factors related to obesity could determine metabolic rates & how the body processes food. Studies on obesity genetics continue to indicate that heredity can contribute to obesity. ...Read more
Why cystic fibrosis only affects the caucasian population and how the disease may have originated?
not true: Cystic fibrosis is a metabolic disorder more common in caucasions by present in many populations.The incidence is 1/3500 caucasion, 1/17, 000 african american, 1/80, 000 native american. It arises in mutations in the cftr gene that regulates cellular transport of chloride.There are in excess of 700 known mutations recorded but most common is the delta 508. ...Read more
Tell me about muscular dystrophy DMD. The test like CPK to identify the problem measured in which unit and is there different type of CPK test?
Muscular dystrophy: Muscular dystrophy is a genetic disorder affecting the muscles. There are different types with different modes of inheritance, age of onset and severity. The CK (or CPK), creatinine kinase are usually elevated in any one. There are different isoenzymes for CK yet it is the total CK that is measured and important in muscular dystrophy. The final diagnosis is made by genetic testing or other tests ...Read more
