Muscular Dystrophy-dystroglycanopathy (congenital With Mental Retardation), Type B, 6; Mddgb6

Description

MDDGB6 is an autosomal recessive congenital muscular dystrophy with mental retardation and structural brain abnormalities (Longman et al., 2003). It is part of a group of similar disorders resulting from defective glycosylation of alpha-dystroglycan (DAG1 ), collectively known as 'dystroglycanopathies' (Mercuri et al., 2009).For a discussion of genetic heterogeneity of congenital muscular dystrophy-dystroglycanopathy type B, see MDDGB1 (OMIM ).
