POMT1 and muscular dystrophy-dystroglycanopathy, type A: To date, the majority of genes associated with WWS, like O-Mannosyltransferase Gene (POMT1) [5] and Fukutin-related protein (FKRP) [6], have been implicated in causing defects in the glycosylation of proteins mainly of α-dystroglycan encoded by the DAG1 gene, which is also a cause of WWS [7].
