The carriers of RBM20 alterations were more likely to have sustained VT (25%) than idiopathic DCM cohort (2%, p < 0.001) and TTNtv variants cohort (1%, p < 0.001) and, similar to LMNA patients (21%, NS), defined as sustained VT or VF on monitoring for idiopathic DCM, TTNtv, and LMNA, and as sudden cardiac arrest or ICD discharge for RBM20 [32] (Table 2). Here, RBM20 is linked to familial dilated cardiomyopathy.
