More than 50 genes associated with DCM have been reported; nevertheless, previous studies have indicated that variants in 17 genes (viz, MYH7, DMD, DSP, VCL, DES, LDB3SCN5A, ACTC1, NEXN, TNNT2, RBM20, PLN, LMNA, TPM1, TNNC1, BAG3 and TTN) constitute the majority of candidate causal and likely candidate causal alterations in DCM.88, 91, 92, 93, 94, 95. Here, MYH7 is linked to familial dilated cardiomyopathy.
