Gene ID: 127534

About GJB4

Cytogenetic location: 1p34.3 Genomic coordinates (GRCh38): 1:34,759,740-34,762,327 (from NCBI)

This gene has 1 transcript (splice variant), 351 orthologues, 20 paralogues and is associated with 2 phenotypes. Biased expression in skin (RPKM 10.4), gall bladder (RPKM 1.6) and 2 other tissues.

Summary

This gene encodes a transmembrane connexin protein that is a component of gap junctions. Mutations in this gene have been associated with erythrokeratodermia variabilis, progressive symmetric erythrokeratoderma and hearing impairment. [provided by RefSeq, Dec 2009]
