MGI Phenotype FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] The protein encoded by this gene is a connexin and is a component of lens fiber gap junctions. Defects in this gene are a cause of zonular pulverulent cataract type 3 (CZP3). [provided by RefSeq, Jan 2010]
PHENOTYPE: Homozygous mutants exhibit lens nuclear cataracts associated with breakdown of gamma crystallin. Severity of the defect is influenced by genetic background. [provided by MGI curators]
