MGI Phenotype

FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] 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. [provided by RefSeq, Jul 2008]
PHENOTYPE: Mutant mice which maintain expression of the A isoform and lack expression of the B isoform are predisposed to episodic sinus bradycardia. Mice with mutations causing defects in both isoforms are embryonic lethal with defects in cardiac development and function. [provided by MGI curators]
