Muscular dystrophies due to reduced glycosylation of alpha-dystroglycan have emerged as a common group of conditions, now referred to as dystroglycanopathies. The phenotypic severity of dystroglycanopathy patients is extremely variable. At the most severe end of the clinical spectrum are Walker-Warburg syndrome (WWS), Muscle-eye-brain disease (MEB), and Fukuyama congenital muscular dystrophy (FCMD). These are termed muscular dystrophy-dystroglycanopathy type A (MDDGA), and characterized by congenital muscular dystrophy with severe structural brain and eye abnormalities, which in WWS results in early infantile death.
