The limb-girdle muscular dystrophies (LGMD) is a generic term for a group of rare progressive genetic disorders that are characterized by wasting (atrophy) and weakness of the voluntary muscles of the hip and shoulder areas (limb-girdle area). Muscle weakness and atrophy are progressive and may spread to affect other muscles of the body. Approximately 15 different subtypes have been identified based upon abnormal changes (mutations) of certain genes. The age at onset, severity, and progression of symptoms of these subtypes may vary greatly from case to case, even among individuals in the same family. Some individuals may have a mild, slowly progressive form of the disorders; other may have a rapidly progressive form of the disorder that causes severe disability.
The term limb-girdle muscular dystrophies is a general term that encompasses several disorders. These disorders can now be distinguished by genetic and protein analysis. At least 15 subtypes have been identified. The various forms of LGMD may be inherited as autosomal dominant or recessive traits. Autosomal dominant LGMD is known as LGMD1 and has five subtypes (LGMD1A-1E). Autosomal recessive LGMD is known as LGMD2 and has 11 subtypes (LGMDA-K).
Additional terminology has been used in the past to describe forms of muscular dystrophy that are now classified under LGMD. These terms include scapulohumeral (Erb) muscular dystrophy, pelvifemoral (Leyden-Mobius) muscular dystrophy, and severe childhood autosomal recessive muscular dystrophy (SCARMD).
