RYR2 and catecholaminergic polymorphic ventricular tachycardia: Multiple missense mutations in RyR2 are related to arrhythmogenic right ventricular cardiomyopathy type 2 (Tiso et al., 2001), and catecholaminergic polymorphic ventricular tachycardia (CPVT; Priori et al., 2001; Duan et al., 2018), two inherited forms of sudden cardiac death.
