Muscular dystrophy refers to a group of genetic diseases marked by progressive damage to and weakness of facial, limb, breathing, and heart muscles. It is due to a lack of key protein. Find out more about the types, symptoms, and treatment.
When one of these proteins, dystrophin, is absent, the result is Duchenne muscular dystrophy; poor or inadequate dystrophin results in Becker muscular dystrophy. Cause of DMD. Until the 1980s, little was known about the cause of any of the forms of muscular dystrophy. In 1986, MDA-supported researchers identified a gene on the X chromosome that, when flawed (mutated), causes both Duchenne and Becker muscular dystrophies. Genes contain codes, or recipes, for proteins, which are important biological components in all forms of life.
