摘要: 目的 了解中国人常见遗传性耳聋基因携带率和突变谱。 方法 采集2018年1月至10月本院出生的2545例新生儿足跟血,微阵列芯片法对常见耳聋基因突变进行筛查。 结果 共发现119例新生儿携带耳聋基因突变,其中GJB2突变携带者60例(2.36%),男女比1∶1 (30/30);SLC26A4突变携带者48例(1.88%),男女比接近1∶1 (26/22);线粒体12S rRNA基因突变携带者5例(0.20%);GJB3突变携带者5例(0.20%);1例有GJB2基因235位点和SLC26A4基因IVS7-2位点双杂合突变(0.04%)。另外还发现SLC26A4基因1174A > T、1229C > T和15+5G > A突变各1例。 结论 初步了解中国人耳聋基因位点分布,可为遗传性耳聋防控参考。

Abstract: Objective To investigate the mutative rate and spectrum of common hereditary deafness genes in Chinese. Methods Heel blood samples from 2545 infants born from January to October, 2018, were collected, and screened with microarray chip. Results There were 119 children with mutation of deafness gene, including 60 cases (2.36%) with GJB2 mutation, male/female = 1∶1 (30/30); 48 (1.88%) with SLC26A4 mutation, male/female nearly 1∶1 (26/22); five (0.20%) with mutation of mitochondrial 12S rRNA gene; five (0.20%) with GJB3 mutation; one (0.04%) with heterozygosis in GJB2 235 and SLC26A4 IVS7-2 mutation. Other more, mutations of 1174A > T, 1229C > T and 15+5G>A of SLC26A4 were found in one child, respectively. Conclusion The distribution of deafness gene loci has been investigated, which can be reference for prevention and control of hereditary deafness in Chinese.
