The distribution of disease-associated variants in this cohort revealed that 88.1% of all variants were associated with DCM genes (e.g., TTN, LMNA, SCN5A, RBM20, MYH7 and TPM1), 3.9% to HCM genes (MYBPC3 and MYH7), and 7.9% to ARVC genes (PKP2 and DSC2). Here, RBM20 is linked to familial dilated cardiomyopathy.
