In humans, multiple genes have been implicated in muscular dystrophy; in addition, in most cases, any specific gene is implicated in multiple forms of the disease. This report is for muscular dystrophy, limb-girdle (LGMD), autosomal recessive, a form of muscular dystrophy that primarily affects proximal muscles. A list of LGMD autosomal recessive subtypes, as defined by OMIM, can be found by following the links in the "OMIM phenotypic series" section, below. A subset of these can be found in the table below, with links to more detailed reports for subtypes that have been investigated using fly models. See also 'muscular dystrophy, limb-girdle, autosomal dominant' (FBhh0001207).

Limb-girdle muscular dystrophy primarily affects the proximal muscles, resulting in difficulty walking. The age at onset varies, but most patients show onset in childhood, and the disorder is progressive. Involvement is first evident in either the pelvic or, less frequently, the shoulder girdle, often with asymmetry of wasting when the upper limbs are first involved; spread from the lower to the upper limbs or vice versa occurs within 20 years (Chung and Morton, 1959; pubmed:13810212).
