Muscular dystrophies are a group of inherited muscle disorders in which one or more genes needed for normal muscle structure and function are defective, leading to muscle weakness and muscle wasting (dystrophy) of varying severity.
Forms of limb-girdle dystrophy can be inherited in various ways because different genes may be involved. Sometimes only one defective gene is needed, which can be inherited from either parent (autosomal dominant). Sometimes a defective gene must be inherited form both parents (autosomal recessive).
Limb-girdle dystrophy causes weakness in the muscles of either the pelvis (Leyden-Möbius muscular dystrophy) or the shoulder (Erb muscular dystrophy). Males and females are affected equally. These inherited disorders often begin in early childhood but may not begin until adulthood. They rarely cause serious weakness.
