Genes associated with DCM as the predominant phenotype include TTN (Titin, 20–25% of cases), LMNA (Lamin A/C, ~5% of cases), MYH7 (Myosin heavy chain 7, ~4% of cases), TNNT2 (Troponin T, ~2% of cases), MYBPC3 (Myosin-binding protein C, ~2% of cases), MYPN (Myopalladin, ~2% of cases), SCN5A (Sodium channel α unit, ~2% of cases), and PLN (Phospholamban, 1% of cases) [3]. Here, TNNT2 is linked to familial dilated cardiomyopathy.
