MDDGB4 is a rare autosomal recessive congenital muscular dystrophy that is part of a group of similar disorders resulting from defective glycosylation of alpha-dystroglycan (DAG1; 128239), collectively known as 'dystroglycanopathies.' In contrast to most dystroglycanopathies, impaired intellectual development is not a feature of MDDGB4 (Godfrey et al., 2007). For a discussion of genetic heterogeneity of congenital muscular dystrophy-dystroglycanopathy type B, see MDDGB1 (613155). [from OMIM]
