目的:应用遗传性耳聋基因芯片对南通地区新生儿进行耳聋基因突变检测,统计常见耳聋突变的携带率,以期早发现、早诊断、早干预。方法:对478例在南通地区分娩活产新生儿出生后3天内采集足跟血用耳聋基因芯片检测国人常见4个耳聋基因9个位点,包括GJB2(35delG,176del16,235delC,299delAT),GJB3(538C>T), SLC26A4(2168A>G,IVS7~2A>G),线粒体12SrRNA (1494C>T,1555A>G)。结果:478例基因筛查,453例通过,16例GJB2阳性,其中235del 杂合突变15例,299delAT杂合突变1例;SLC26A4 IVS7~2A>G杂合突变7例;GJB3538 C>T杂合突变1例;线粒体12SrRNA 1494C>T均质突变1例。结论:南通地区新生儿耳聋基因有一定的携带率,该筛查将有助于对潜在耳聋的发现及预防,具有良好的临床应用价值。
目的:應用遺傳性耳聾基因芯片對南通地區新生兒進行耳聾基因突變檢測,統計常見耳聾突變的攜帶率,以期早髮現、早診斷、早榦預。方法:對478例在南通地區分娩活產新生兒齣生後3天內採集足跟血用耳聾基因芯片檢測國人常見4箇耳聾基因9箇位點,包括GJB2(35delG,176del16,235delC,299delAT),GJB3(538C>T), SLC26A4(2168A>G,IVS7~2A>G),線粒體12SrRNA (1494C>T,1555A>G)。結果:478例基因篩查,453例通過,16例GJB2暘性,其中235del 雜閤突變15例,299delAT雜閤突變1例;SLC26A4 IVS7~2A>G雜閤突變7例;GJB3538 C>T雜閤突變1例;線粒體12SrRNA 1494C>T均質突變1例。結論:南通地區新生兒耳聾基因有一定的攜帶率,該篩查將有助于對潛在耳聾的髮現及預防,具有良好的臨床應用價值。

To apply of gene chip to detect mutation of deafness gene in the newborns in nantong area and calculating the carrying rate mutation of common deafness gene for early detection , diagnosis and intervention .Methods:Collecting 478 newborns'heel blood who borned within three days and detecting following nine loci of deafness genes with deafness gene chip :GJB2(35delG,176del16, 235delC,299delAT),GJB3 (538C>T), SLC26A4 (2168A>G,IVS7-2A>G),mitochondria 12SrRNA (1494C>T,1555A>G).Re-sults:Among 478 cases of genetic screening , 453 cases passed, 16 cases were found to be GJB2 positive, of which, 15 cases 235del het-erozygous mutation, one case 299delAT heterozygous;seven cases SLC26A4 IVS7-2A>G heterozygous mutation;one case GJB3 538 C>T heterozygous mutation;one case mitochondrial 12SrRNA 1494C>T mutation in homogeneous.Conclusion:A certain carrier rate of deafness gene could have been found in newborns in Nantong region , which contributes to the detection and prevention of potential hearing loss of newborns and worth broad utilization in clinic .
