The muscular dystrophies are a group of genetic and hereditary muscle diseases; characterized by progressive skeletal muscle weakness, defects in muscle proteins, and the death of muscle cells and tissue. In some forms of muscular dystrophy, cardiac and smooth muscles are affected. The muscular dystrophies are the most-known hereditary diseases.
The dystrophin gene is located on the X chromosome, thus making DMD a 'sex-linked' disorder. Accordingly, muscular dystrophies are much more common in males, as females have two copies of the X chromosome while males have only one.
