Update of the Spectrum of GJB2 Mutations in 107 Patients with Nonsyndromic Hearing Loss in the Fujian Population of China

Mutations in the GJB2 gene, encoding connexin26, which is expressed in the inner ear, have been shown to be responsible for the majority of nonsyndromic hearing loss (NSHL) cases. To update and evaluate the spectrum and prevalence of GJB2 mutations in the Fujian population, we screened exon 2 (coding), exon 1, and flanking introns of GJB2 in 107 NSHL probands and 61 individuals with normal hearing. Twelve different variants were identified, …
