These variants include risk alleles in CACNA1C (malignant hyperthermia), RYR1 (malignant hyperthermia), KCNH2 (long QT syndrome), SCN5A (long QT syndrome), RYR2 (catecholaminergic polymorphic ventricular tachycardia), and LDLR (hyperlipidemia). The gene discussed is LDLR; the disease is hyperlipidemia.
