Short QT syndrome type 1
Introduction
Overview
Overview
This variant is due to a gain-of-function mutation of the rapid component of the delayed rectifier potassium current HERG (KCNH2) channel(IKr)[1]. The variant is a result of missense mutations which increase IKr. It is associated with sudden death and sudden infant death syndrome.
