目的 探讨唐山市新生儿携带的常见耳聋基因突变热点及其对听力的影响,为耳聋基因咨询及听力障碍的干预提供依据.方法 回顾性分析在唐山市妇幼保健院分娩并行听力与耳聋基因联合筛查的新生儿共 5298 例,听力筛查包括耳声发射和自动听性脑干反应;采用博奥晶典生物芯片检测 4 个常见耳聋突变基因的 15 个位点,包括GJB2 基因(c.35delG,c.176_191del16,c.235delC,c.299_300delA.c.109G>A)、GJB3 基因(c.538 C>T)、SLC26A4 基因(IVS7-2A>G,c.2168A>G,c.1975 G>C,c.2027 T>A,c.1226G>A,IVS15+5 G>A,c.1174A>T,c.1229C>T)、12srRNA基因(m.1555A>G).结果 耳聋基因突变携带率4.41(234/5298),为携带耳聋基因突变组;未携带耳聋基因突变的样本中随机选择 2 404 例,为非携带耳聋基因突变组(对照组).携带耳聋基因突变组中GJB2、SLC26A4、GJB3、mtDNA12SrRNA、双基因杂合突变及单基因杂合突变携带率分别为2.49%(132/5298)、1.34%(71/5298)、0.28%(15/5298)、0.19%(10/5298)、0.09%(5/5298)及0.02%(1/5298).携带耳聋基因突变组听力初筛 234 例,通过率 91.88%(215/234),未通过率 8.12%(19/234),复筛 153 例,确诊率 1.96%(3/153).非携带组入组 2404 例,初筛通过率 93.97%(2259/2404),未通过率 6.03%(145/2404),复筛 105 例,确诊率 0.08%(2/2364).两组通过率、双耳未通过率及确诊率差异有统计学意义(P=0.001,P<0.001,P<0.001),结论 唐山市新生儿携带常见耳聋基因突变有一定的地域性,携带耳聋基因是听力障碍的高危因素,听力与耳聋基因联合筛查有利于听力障碍的检出.
Objective To explore the hotspots of deafness gene mutation and its effect on hearing in newborns in Tangshan city.Methods The data of 5298 newborns born in Tangshan maternal and child health care hospital were analyzed retrospectively and hearing and deafness genes were screened.Hearing was screened by otoacoustic emission and auditory brainstem response,and the genetic basis of newborn deafness covering 15 variants in 4 genes was screened by the gene chip.Genes included GJB2(c.35delG,c.176_191del16,c.235delC,c.299_300delA.c.109G>A),GJB3(c.GJB3538 C>T),SLC26A4(IVS7-2A>G,c.2168A>G,c.1975 G>C,c.2027 T>A,c.1226G>A,IVS15+5 G>A,c.1174A>T,c.1229C>T),and 12srRNA(m.1555A>G).Results In total,234 patients with deafness genes were identified as the deafness gene carrier group.A total of 2 404 patients were randomly selected from 5064 without deafness genes as the non-deafness gene carrier group to analyze the mutation hotspots of the deafness genes and their effects on hearing status.The prevalence of deafness genes was 4.41%(234/5 298).The positive rates of GJB2,SLC26A4,GJB3,mtDNA12SrRNA,double gene mutation,and single gene mutation were 2.49%(132/5298),1.34%(71/5298),0.28%(15/5298),0.19%(10/5298),0.09%(5/5298),and 0.02%(1/5298),which differed from previous reports.In primary hearing screening,the for deafness gene carrying group had a pass rate of 91.88%(215/234),a failure rate of 8.12%(19/234),and a diagnosis rate of 1.96%(3/153).In the non-carrier group,the pass rate 93.97%(2 259/2 404),the failure rate was 6.03%(145/2404),and the diagnosis rate was 0.08%(2/2364).The pass rate for bilateral ear,failure rate for bilateral ear,and diagno-sis rate were different(P=0.001,P<0.001,P<0.001,respectively).Conclusion The common gene mutation for deafness in newborns in Tangshan City has a certain regional character,and carrying deafness genes is a high-risk factor of hearing impairment.The combined screening of hearing and hearing loss genes is beneficial for detecting hearing impairment.
