Gene Description GJB2, gap junction protein beta 2, encodes a component of the gap junction channel (PMID: 19340074) that facilitates the exchange of ions and biological molecules between cells and the environment (PMID: 36187349, PMID: 23048025, PMID: 9508777), playing an essential role in hearing function and epithelial development (PMID: 36187349, PMID: 37106706, PMID: 11912510). GJB2 mutations have been identified in esophageal squamous cell cancer (PMID: 33889545), prostate cancer (PMID: 35734583), and aberrant expression of GJB2 has been reported in multiple tumor types (PMID: 37427102), including bladder cancer (PMID: 12576868).
