Autosomal recessive limb-girdle muscular dystrophy type 2M

MDDGC4 is an autosomal recessive muscular dystrophy with onset in infancy or early childhood. Cognition and brain structure are usually normal (Godfrey et al., 2006). It is part of a group of similar disorders resulting from defective glycosylation of alpha-dystroglycan (DAG1; 128239), collectively known as 'dystroglycanopathies' (Mercuri et al., 2009).
