About GJB3

Cytogenetic location: 1p34.3 Genomic coordinates (GRCh38): 1:34,781,214-34,786,364 (from NCBI)

This gene has 2 transcripts (splice variants), 229 orthologues, 20 paralogues and is associated with 11 phenotypes. Biased expression in skin (RPKM 23.0), esophagus (RPKM 12.6) and 4 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. Mutations in this gene can cause non-syndromic deafness or erythrokeratodermia variabilis, a skin disorder. Alternative splicing results in multiple transcript variants encoding the same protein.
