Limb-girdle muscular dystrophy
A group of muscular dystrophies, probably heterogeneous in nature. Onset usually in childhood or early adulthood and both sexes affected. Characterized by weakness and wasting, usually symmetric, of the pelvic girdle muscles, the shoulder girdle muscles, or both, but not the facial muscles. Muscle pseudohypertrophy, heart involvement, and mental retardation are absent. Autosomal dominant and recessive inheritance have been described.
