✦ Synopsis
Recently, a 342-kb deletion involving GJB6 was associated with autosomal-recessive non-syndromic hearing loss (NSHL) and in combination with a GJB2 mutation with digenic NSHL. This deletion was the second most common mutation causing prelingual NSHL in Spain, and was frequently observed in patients from France and Israel. We screened 393 patients with NSHL being negative or heterozygous for GJB2 mutations for this GJB6 deletion using a multiplex PCR. Most patients were of Austrian (84.2%), and the other patients were of Turkish, Serbian, and Bosnian origin. None of these patients was carrying the deletion in GJB6 indicating that the occurrence of this deletion is restricted to certain populations.
