Causative variants were found in nine patients with congenital muscular dystrophy in the ACTA1 gene (in one patient), GFPT1 (in one patient), PIGY (in two patients), POMT1 (in one patient), MCU1 (one patient), RYR1 (one patient), and TTN (one patient). Here, ACTA1 is linked to congenital muscular dystrophy.
