Two patients had PVs in genes associated with familial hypercholesterolemia (APOB and LDLR), three had PVs in genes associated with arrhythmic right ventricular cardiomyopathy (DSC2, DSG2, and PKP2), and one patient had a PV in KCNQ1, which is associated with long QT syndrome. Here, PKP2 is linked to familial hypercholesterolemia.
