A novel gamma-sarcoglycan mutation causing childhood onset, slowly progressive limb girdle muscular dystrophy.
Limb girdle muscular dystrophy is a heterogeneous group of disorders. One autosomal recessive subtype, LGMD2C, has been linked to chromosome 13, and is caused by gamma-sarcoglycan deficiency in muscle. This report describes a novel missense mutation identified in a large consanguineous Dutch family with LGMD. This mutation leads to reduction of gamma-sarcoglycan, and gives rise to a childhood-onset, slowly-progressive dystrophy.
