Distal myopathy (or distal muscular dystrophy) is a general term for a group of rare progressive genetic disorders characterized by wasting (atrophy) and weakness of the voluntary distal muscles. The distal muscles are those farther from the center of the body and include the muscles of the lower arms and legs and the hands and feet. Conversely, the proximal muscles are the muscles closest to the center of the body such as the muscles of the shoulder, pelvis, and upper arms and legs. Although age of onset can occur anytime from infancy to adulthood, most forms develop later in life and are slowly progressive. Inheritance is autosomal dominant or recessive.
The distal myopathies belong to a larger group of disorders known as the muscular dystrophies. The muscular dystrophies are characterized by weakness and degeneration of various voluntary muscles of the body. Approximately 30 different disorders make up the muscular dystrophies. The disorders affect different muscles and have different ages of onset, severity and inheritance patterns.
