MGI Phenotype

FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] This gene encodes a transmembrane connexin protein that is necessary for lens growth and maturation of lens fiber cells. The encoded protein is a component of gap junction channels and functions in a calcium and pH-dependent manner. Mutations in this gene have been associated with zonular pulverulent cataracts, nuclear progressive cataracts, and cataract-microcornea syndrome. [provided by RefSeq, Dec 2009]
PHENOTYPE: Homozygous mutants exhibit microphthalmia, with small lenses and nuclear or total cataracts. Heterozygotes may be equally or less affected, depending on the particular mutation and the genetic background. [provided by MGI curators]
