In the present study, the authors reported a family of a male proband with prelingual, profound non-syndromic hearing impairment homozygous for p.W24X mutation in GJB2gene, arising as a result of maternal uniparental disomy of a part of chromosome 13q.

 

Key words: Hearing impairment, p.W24X mutation, uniparental disomy.
