GENE INFORMATION
Gene name	KCNJ18 (HGNC Symbol)
Synonyms	KIR2.6, TTPP2
Description	Potassium channel, inwardly rectifying subfamily J, member 18 (HGNC Symbol)
Entrez gene summary	This gene encodes a member of the inwardly rectifying potassium channel family. Transcription of this locus is regulated by thyroid hormone, and the encoded protein plays a role in resting membrane potential maintenance. Mutations in this locus have been associated with thyrotoxic hypokalemic periodic paralysis. [provided by RefSeq, Jan 2013]
