A growing number of causative genes for congenital MD (CMD) with abnormal α-DG glycosylation, including FUKUTIN, POMGNT1, POMGNT2, FUKUTIN RELATED PROTEIN (FKRP), and LARGE, have been recognized, and to date, at least eighteen have been reported [8] (Fig 1B). This evidence concerns the gene POMGNT2 and congenital muscular dystrophy.
