High-throughput phenotyping of heteromeric human ether- à-go-go-related gene potassium channel variants can discriminate pathogenic from rare benign variants
KCNH2 encodes the human ether- à-go-go-related gene (hERG) potassium channel, which passes the rapid delayed rectifier potassium current, IKr. Loss-of-function variants in KCNH2 cause long QT syndrome type 2 (LQTS2) which is associated with a markedly increased risk of cardiac arrhythmias. The majority of rare KCNH2 variants how ever are likely to be benign.
