Clinical phenotype and mutations in connexin 26 (DFNB1/GJB2), the most common cause of childhood hearing loss.

Abstract excerpt

Mutations in the gene for connexin 26, GJB2, are the most common cause of hearing loss in American and European populations, with a carrier rate of about 3%-a rate similar to that for cystic fibrosis. A single mutation, 35delG, is responsible for most of this autosomal recessive hearing loss, DFNB1. A broad spectrum of mutations in GJB2 has been found to be associated with hearing loss, including another deletion...
