MGI Phenotype FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] This gene is 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. The encoded protein is the major protein of gap junctions in the heart that are thought to have a crucial role in the synchronized contraction of the heart and in embryonic development. A related intronless pseudogene has been mapped to chromosome 5. Mutations in this gene have been associated with oculodentodigital dysplasia, autosomal recessive craniometaphyseal dysplasia and heart malformations. [provided by RefSeq, May 2014]
PHENOTYPE: Mutant homozygotes are neonatal lethal with heart and outflow tract malformations, eye lens anomalies, and male germ cell deficiency. Conditional deletion in ovary affects follicular development, in astrocytes enhances locomotor activity, and in neural cells produces behavioral and neural defects. [provided by MGI curators]
