We screened the pathogenic or likely pathogenic variants for DCM in our exome sequencing data in the following sixteen genes associated with DCM in previous studies: ACTC1, BAG3, DES, DMD, DNAJC19, EMD, LMNA, MYH7, PLN, RBM20, SCN5A, TAZ, TNNI3, TNNT2, TPM1, and TTN [8,17]. This evidence concerns the gene SCN5A and familial dilated cardiomyopathy.
