Spectrum of <i>GJB2</i> mutations causing deafness in the British Bangladeshi population

Abstract

Mutations in GJB2 are responsible for over one quarter of non-syndromic sensorineural deafness in the British Bangladeshi population. It is recommended that all Bangladeshi patients with non-syndromic hearing loss should be first tested for GJB2 mutations before requesting other aetiological investigations.
