MGI Phenotype

FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] This gene encodes a member of the G protein-coupled inwardly-rectifying potassium channel family of inward rectifier potassium channels. This type of potassium channel allows a greater flow of potassium into the cell than out of it. These proteins modulate many physiological processes, including heart rate in cardiac cells and circuit activity in neuronal cells, through G-protein coupled receptor stimulation. Mutations in this gene are associated with Keppen-Lubinsky Syndrome, a rare condition characterized by severe developmental delay, facial dysmorphism, and intellectual disability. [provided by RefSeq, Apr 2015]
PHENOTYPE: A spontaneous mutation exhibits small size, ataxia, hypotonia, high periweaning mortality, Purkinje cell defects, and male sterility. Homozygotes for a targeted null mutation exhibit increased susceptibility to spontaneous and drug-induced seizures. [provided by MGI curators]
