An important gene associated with Myasthenic Syndrome, Congenital, 13 is DPAGT1 (Dolichyl-Phosphate N-Acetylglucosaminephosphotransferase 1), and among its related pathways/superpathways are Acetylcholine binding and downstream events and ErbB2/ErbB3 signaling events. Affiliated tissues include skeletal muscle and brain, and related phenotypes are proximal muscle weakness and muscle fiber tubular inclusions
