Front Aging Neurosci:葡萄牙老年群体中耳聋和耳鸣生物标记的研究

2017-11-27 AlexYang MedSci原创

老年性耳聋或者年龄相关的听力损失(ARHL)是一种普遍存在的健康问题。据估计,该病到2025年会影响超过15亿的人口。另外,耳鸣在大多数的老年性耳聋病人中存在。谷氨酸代谢性受体7(GRM7)和N-乙酰转移酶2(NAT2)是老年性耳聋的遗传标记的部分。最近,有研究人员探索了在葡萄牙人口群体样本中,听力损失的模式和GRM7和NAT2作为老年性耳聋和耳鸣遗传标记的可能。研究人员从78名个体(33名男性和

老年性耳聋或者年龄相关的听力损失(ARHL)是一种普遍存在的健康问题。据估计,该病到2025年会影响超过15亿的人口。另外,耳鸣在大多数的老年性耳聋病人中存在。谷氨酸代谢性受体7(GRM7)和N-乙酰转移酶2(NAT2)是老年性耳聋的遗传标记的部分。最近,有研究人员探索了在葡萄牙人口群体样本中,听力损失的模式和GRM7NAT2作为老年性耳聋和耳鸣遗传标记的可能。

研究人员从78名个体(33名男性和45名女性)中进行了样本筛选。其中在GRM7基因中最常观察到T等位基因(60.3% T/T和33.3% A/T)。分别与A/A基因型和A/T基因型相比,T/T基因型的个体具有患ARHL更高的风险,并且低33%的的耳鸣风险。慢乙酰化反应(53%)是NAT2中最为常见的表型,并且在男性中更常见(55.8%)。中速乙酰化反应是第二大常见表型(35.9%),同样在男性中更为常见(82.6%)。噪音接触个体和患有高频率听力损失的个体具有患耳鸣更高的风险。他们的数据表明了GRM7的等位基因AT对耳鸣的严重性具有显著的影响。

最后,研究人员指出,每年HL增加的比例为9%。ARHL的风险与GRM7或者NAT2均没有显著的相关性。然而,研究人员并不能从他们的数据中对是否T等位基因在GRM7中的出现能够增加患ARHL的风险或者是否A等位基因具有保护性的影响来下结论。GRM7中的A/T基因型可以作为耳鸣严重度的潜在生物标记。研究人员也指出,他们的研究首次评估了GRM7NAT2对耳鸣的影响。
