What causes muscular dystrophy?
Often thought of as a single disorder, muscular dystrophy is a group of genetic diseases characterized by progressive weakness and degen­eration of the skeletal muscles that control movement. Missing or abnormal dystrophin causes muscular dystrophies.

There are 30 types of muscular dystrophies and they are subdivided by mode of inheritance, age of onset, and clinical features. Discovery of the gene that causes the most common forms of muscular dystrophy took many years because dystrophin compromises only 0.002 percent of the protein in skeletal muscle. There is no specific treatment for muscular dystrophies. Ultimately, fat and connective tissue replace muscle.
