These patients showed overlapping symptoms with DMD/BMD but turned out to be principally affected by limb-girdle muscular dystrophies, as we found disease causing variants in the following genes: FKRP (4), SGCA (2), SGCG (2), SGCB (1), CAPN3 (1), FKTN (1), POMT2 (2), SYNE1 (1), COL6A1 (1), COL6A3 (1) and PHKA1 (1). This evidence concerns the gene FKTN and muscular dystrophy.
