Duchenne Muscular Dystrophy (DMD): Causes, Symptoms, Treatment
The faulty genes (mutations) that cause muscular dystrophy prevent the body from producing the proteins required to develop healthy muscles. There are several types of muscular dystrophy. Symptoms of the most common type begin in childhood, mostly in boys. Other types do not surface until adulthood. There is no cure for muscular dystrophy.
