编码差距连接β-2蛋白连接蛋白26的GJB 2中的突变与常染色体隐性非综合征感音神经性听力损失(NSHL)、常染色体显性NSHL和几种形式的综合征感音神经性听力损失相关[Denoyelle等人,1997,1998; Kelsell等人,1997年; Richard等人,1998,2002,2004; Maestrini等人,1999;货车Geel等人,2002;货车斯滕塞尔等人,2002; Brown等人,2003年]。编码差距连接β-6蛋白连接蛋白30的GJB 6中的突变与常染色体隐性NSHL、常染色体显性NSHL和有汗性外胚层发育不良相关[Grifa et al.,1999; Lamartine等人,2000; Lerer等人,2001; Pallares-Ruiz等人,2002; del Castillo等人,GJB 2和GJB 6在人染色体13 q12上彼此相邻,并且一起包含常染色体隐性NSHL基因座DFNB 1 [货车Camp和Smith,2007]。定位于DFNB 1的常染色体隐性NSHL由GJB 2中的双等位基因突变、GJB 6中的双等位基因突变或GJB 2和GJB 6中的复合杂合突变引起[Denoyelle et al.,1997; Kelsell等人,1997; Lerer等人,2001; Pallares-Ruiz等人,2002; del Castillo等人,2002; Del Castillo等人,2005年]。迄今为止报道的DFNB 1突变包括GJB 2中的超过80个突变和涉及GJB 6的两个大缺失[Lerer et al.,2001; Pallares-Ruiz等人,2002; del Castillo等人,2002; Del Castillo等人,2005; Ballana等人,2007年]。在这项研究中,评估了一组听力受损患者和一个多种族对照组的GJB 2突变和两个已知的涉及GJB 6的缺失。
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.
