Mutations in GJB2, encoding the gap junction beta-2 protein Connexin 26, are associated with autosomal recessive nonsyndromic sensorineural hearing loss (NSHL), autosomal dominant NSHL, and several forms of syndromic sensorineural hearing loss [Denoyelle et al., 1997, 1998; Kelsell et al., 1997; Richard et al., 1998, 2002, 2004; Maestrini et al., 1999; van Geel et al., 2002; van Steensel et al., 2002; Brown et al., 2003]. Mutations in GJB6, encoding the gap junction beta-6 protein Connexin 30, are associated with autosomal recessive NSHL, autosomal dominant NSHL, and hidrotic ectodermal dysplasia [Grifa et al., 1999; Lamartine et al., 2000; Lerer et al., 2001; Pallares-Ruiz et al., 2002; del Castillo et al., 2002].GJB2 and GJB6 lie adjacent to one another on human chromosome 13q12 and together comprise the autosomal recessive NSHL locus DFNB1 [Van Camp and Smith, 2007]. Autosomal recessive NSHL that maps to DFNB1 is caused by biallelic mutations in GJB2, biallelic mutations in GJB6, or compound heterozygous mutations in GJB2 and GJB6 [Denoyelle et al., 1997; Kelsell et al., 1997; Lerer et al., 2001; Pallares-Ruiz et al., 2002; del Castillo et al., 2002; Del Castillo et al., 2005]. DFNB1 mutations reported to date include more than 80 mutations in GJB2 and two large deletions involving GJB6 [Lerer et al., 2001; Pallares-Ruiz et al., 2002; del Castillo et al., 2002; Del Castillo et al., 2005; Ballana et al., 2007]. In this study, a cohort of hearing impaired patients and a multi-ethnic control group were evaluated for mutations in GJB2 and the two known deletions involving GJB6.
