GENE INFORMATION
Gene name	KCNQ3 (HGNC Symbol)
Synonyms	EBN2, Kv7.3
Description	Potassium channel, voltage gated KQT-like subfamily Q, member 3 (HGNC Symbol)
Entrez gene summary	This gene encodes a protein that functions in the regulation of neuronal excitability. The encoded protein forms an M-channel by associating with the products of the related KCNQ2 or KCNQ5 genes, which both encode integral membrane proteins. M-channel currents are inhibited by M1 muscarinic acetylcholine receptors and are activated by retigabine, a novel anti-convulsant drug. Defects in this gene are a cause of benign familial neonatal convulsions type 2 (BFNC2), also known as epilepsy, benign neonatal type 2 (EBN2). Alternative splicing of this gene results in multiple transcript variants. [provided by RefSeq, May 2014]
