Mutations of the connexin 26 gene (GJB2) were studied in 365 apparently unrelated individuals with profound nonsyndromic, sensorineural hearing impairment from Ghana, West Africa. Among 121 mutated chromosomes found, 110 carried the previously described R143W mutation. A total of 6 novel mutations:
Mutations in the Cx26 gene have been shown to cause autosomal recessive nonsyndromic hearing loss (ARNSHL) at the DFNB1 locus on chromosome 13q12. Using direct sequencing, we screened the Cx26 coding region of affected and nonaffected members from seven ARNSHL families either linked to the DFNB1 loc
