GJA1 - gap junction protein alpha 1 Gene
Also Known as HSS; CMDR; CX43; EKVP; GJAL; ODDD; AVSD3; EKVP3; HLHS1; PPKCA
Species: Homo sapiens
About GJA1
This gene has 4 transcripts (splice variants), 124 orthologues, 20 paralogues and is associated with 22 phenotypes. Broad expression in skin (RPKM 198.8), adrenal (RPKM 176.9) and 17 other tissues.
Summary
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]
