MGI Phenotype

FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] Potassium channels are present in most mammalian cells, where they participate in a wide range of physiologic responses. The protein encoded by this gene is an integral membrane protein and inward-rectifier type potassium channel. It is activated by internal ATP and probably plays an important role in potassium homeostasis. The encoded protein has a greater tendency to allow potassium to flow into a cell rather than out of a cell. Mutations in this gene have been associated with antenatal Bartter syndrome, which is characterized by salt wasting, hypokalemic alkalosis, hypercalciuria, and low blood pressure. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jul 2008]
PHENOTYPE: Most homozygotes for a null mutation die before weaning with impaired electrolyte, acid-base, and fluid-volume homeostasis, reduced NaCl absorption in the thick ascending limb, and abnormal tubuloglomerular feedback. A colony of mutants with extended suvival serves as a model for Bartter's syndrome. [provided by MGI curators]
