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 connexin gene family. The encoded protein is a component of gap junctions, which are composed of arrays of intercellular channels that provide a route for the diffusion of low molecular weight materials from cell to cell. Mutations in this gene have been associated with atherosclerosis and a higher risk of myocardial infarction. [provided by RefSeq, Jul 2008]
PHENOTYPE: Homozygous null mutant females are sterile and oocyte development arrests prior to achieving meiotic competence. There is a lack of mature Graafian follicles, failure to ovulate, and formation of premature corpora lutea. [provided by MGI curators]
