BMC Res Notes:SLC26A4对非综合症语前儿童感官听力损失影响研究

2018-08-09 AlexYang MedSci原创

遗传性听力损失(HL)是人类中最常见的感官听力损失。除了GJB2和GJB6基因中的变异之外,在SLC26A4基因中的病理变异已经被报道是遗传性HL的病因之一,并且它主要是在内耳的生理中起作用。最近,有研究人员调查了在非综合症语前儿童感官听力损失巴西患者中SLC26A4基因的变异的流行度。研究人员利用了高分辨率融合技术从与耳聋无关的患者的88个DNA样本中进行了筛选,这些患者值钱不报道在GJB2,

遗传性听力损失(HL)是人类中最常见的感官听力损失。除了GJB2和GJB6基因中的变异之外,在SLC26A4基因中的病理变异已经被报道是遗传性HL的病因之一,并且它主要是在内耳的生理中起作用。最近,有研究人员调查了在非综合症语前儿童感官听力损失巴西患者中SLC26A4基因的变异的流行度。研究人员利用了高分辨率融合技术从与耳聋无关的患者的88个DNA样本中进行了筛选,这些患者值钱不报道在GJB2, GJB6和MT-RNR1中存在变异。

研究发现,SLC26A4基因中的变异的频率为28.4%,并且发现了2个新的变异:p.Ile254Val和p.Asn382Lys。其中,在SLC26A4基因启动子区域的变异c.-66C>G (rs17154282) 是最常见的变异,并且与非综合症语前儿童感官听力损失显著相关。另外,在 GJB2、GJB6和线粒体基因变异之后,SLC26A4基因的变异被认为是巴西及其他群体遗传性HL的下一个最常见的病因,上述结果也与研究人员的数据一致。进一步的是,研究人员还强调了SLC26A4基因在遗传性HL调查中的重要性,原因是该基因变异的流行度已经达到了22.7%。
