Muscular Dystrophy-dystroglycanopathy (congenital With Mental Retardation), Type B, 14; Mddgb14

Description

MDDGB14 is an autosomal recessive congenital muscular dystrophy characterized by severe muscle weakness apparent in infancy and mental retardation. Some patients may have additional features, such as microcephaly, cardiac dysfunction, seizures, or cerebellar hypoplasia. It is part of a group of similar disorders resulting from defective glycosylation of alpha-dystroglycan (DAG1 ), collectively known as 'dystroglycanopathies' (summary by Carss et al., 2013).For a discussion of genetic heterogeneity of congenital muscular dystrophy-dystroglycanopathy type B, see MDDGB1 (OMIM ).
