Genes affected
KCNK1 (HGNC:6272): (potassium two pore domain channel subfamily K member 1) This gene encodes one of the members of the superfamily of potassium channel proteins containing two pore-forming P domains. The product of this gene has not been shown to be a functional channel, however, it may require other non-pore-forming proteins for activity. [provided by RefSeq, Jul 2008]
