Record overview

MGPD IDMGP001718
Gene ID3757
SpeciesHomo sapiens (Human)
Gene Namepotassium channel, voltage gated eag related subfamily H, member 2
Gene Symbol KCNH2
SynonymsERG1; HERG; LQT2; SQT1; ERG-1; H-ERG; HERG1; Kv11.1;
Alternate namespotassium voltage-gated channel subfamily H member 2; eag homolog; eag-related protein 1; ether-a-go-go-related gene potassium channel 1; ether-a-go-go-related potassium channel protein; ether-a-go-go-related protein 1; potassium voltage-gated channel, subfamily H (eag-related), member 2; voltage-gated potassium channel subunit Kv11.1;
Chromosome7
Map Location7q36.1
SummaryThis 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. [provided by RefSeq, Jul 2008]
