Catecholaminergic Polymorphic Ventricular Tachycardia is a life-threatening disorder. The clinical diagnosis is challenging owing to the absence of electrocardiogram and overt structural heart abnormalities in the majority of patients. Approximately 35% of cases remain without a genetic etiology. Here, we identified two genes as a novel promising candidate for CPVT.
