Recently, a homozygous p.W361* variant in the last exon of CASQ2 was identified in a 62‐year‐old female, patient with CPVT onset since childhood for whom sudden death has not been reported to date (Fujisawa et al., 2019). The gene discussed is CASQ2; the disease is catecholaminergic polymorphic ventricular tachycardia.
