What causes distal muscular dystrophy?

All types of distal muscular dystrophy are caused by damaged or defective genes. The particular genetic mutation that causes it depends on which type of the disease you have. In some cases, doctors don't yet know which genes cause certain types of distal muscle dystrophy. Most commonly, the cause is a genetic defect that causes problems in one of the many proteins that make up muscle cells. Because of this lack of protein, the muscle cells don't function properly. This leads to muscle weakness, especially in the forearms, hands, and lower legs.
