Abstract
Gap junctions, which consist of connexins, are intercellular channels that mediate rapid intercellular communication. In the skin, connexins are involved in the regulation of epidermal growth and differentiation. GJB2 encodes connexin26, which is an important skin-expressed gap junction protein. Mutations in GJB2 cause a wide variety of unique disorders, but despite extensive research, their mechanisms of action are poorly understood. The identification of novel diseases caused by mutations in GJB2 may help to illuminate the genotype-phenotype correlation and elucidate the function of different regions of the protein. Here, we report the first account of a family with a GJB2 missense mutation in the second extracellular domain (p.Ser183Phe) that causes skin abnormalities in addition to sensorineural hearing loss.
