KCNH2

  • Official Full Name

    Potassium Voltage-Gated Channel, Subfamily H (Eag-Related), Member 2

  • Overview

    This gene encodes a voltage-activated potassium channel belonging to the eag family. It shares sequence similarity with the Drosophila ether-a-go-go (eag) gene. Mutations in this gene can cause long QT syndrome type 2 (LQT2). Transcript variants encoding distinct isoforms have been identified.
