SCN5A and cardiac rhythm disease: Molecular autopsies mainly include the screening of the genes known to be involved in cardiac arrhythmias, such as KCNQ1, KCNH2, and SCN5A, which are associated with long QT syndrome, and RYR2, which is associated with major catecholaminergic polymorphic ventricular tachycardia (CPVT) [4,5,6].
