Muscular Dystrophy-dystroglycanopathy (congenital With Mental Retardation), Type B, 2; Mddgb2

Description

MDDGB2 is an autosomal recessive congenital muscular dystrophy associated with mental retardation and mild structural brain abnormalities (Yanagisawa et al., 2007). It is part of a group of similar disorders, collectively known as 'dystroglycanopathies,' resulting from defective glycosylation of alpha-dystroglycan (DAG1 ) (Godfrey et al., 2007).For a discussion of genetic heterogeneity of congenital muscular dystrophy-dystroglycanopathy type B, see MDDGB1 (OMIM ).
