Distal Muscular Dystrophy

Also known as distal myopathy, Distal Muscular Dystrophy (MD) primarily affects the distal muscles (those farthest away from the shoulders and hips) in the forearms, hands, lower legs, and feet. Distal dystrophies are typically less severe, progress more slowly, and involve fewer muscles than other forms of MD, although they can spread to other muscles. Distal MD can affect the heart and respiratory muscles. In one form of distal MD, a muscle membrane protein complex called dysferlin is known to be lacking.
