Genes that are causing DCM encode components of sarcomere (TTN, MYH7, TNNT2, TNNI3, TPM1, ACTC1), sarcomere associated proteins (PLN, BAG3), nuclear membrane (LMNA, EMD), cytoskeleton (DES), outer cellular membrane, extracellular matrix (DMD), ion channels (SCN5A), mitochondrial proteins (TAZ, DNAJC19), and splice-regulating proteins (RBM20) [8]. Here, ACTC1 is linked to familial dilated cardiomyopathy.
