Abstract excerpt
Severe to profound hearing impairment affects 1 of every 1000 newborn children each year. Inheritance accounts for 60% of these cases, of which 70% are nonsyndromic. The most common cause of autosomal recessive nonsyndromic hearing loss (ARNSHL) is mutation in GJB2, a gene on chromosome 13, which encodes a gap junction protein named Connexin 26. Mutations in GJB2 are responsible for 40% of genetic childhood...
