Short QT syndrome type 1

Editor-In-Chief: C. Michael Gibson, M.S., M.D. [1]

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.
