摘  要:目的针对育龄妇女群体进行中国人群常见耳聋基因突变筛查,为耳聋患儿产前诊断提供分子流行病学数据基础。方法采用遗传性耳聋基因芯片对324名育龄妇女,包括169名孕妇基因组DNA的GJB2、sLC26A4、GJB3和线粒体12srRNA4个耳聋相关基因的9个致聋突变位点进行检测。结果在324份样本中,携带有耳聋基因突变者共20例,检出率为6.17%。GlJB2基因突变携带者11例(3.40oA,11/324),SLC26A4基因突变携带者7例(2.16%,7/3e4),qB2基因和GJB3基因双突变1例(0.31%,1/324),线粒体12srRNA基因突变携带者1例(O.31%,1/324)。结论常见耳聋基因突变在育龄妇女中有较高的携带率。GJB2基因235delC突变是最常见的突变方式。对听力正常夫妇进行产前耳聋基因筛查是预防聋儿出生的有效手段。Objective To screen for mutations of deafness-related genes among ethic Chinese women of child-bearing age. Methods In 324 women, 9 mutational sites in 4 deafness-related genes (SLC26A4, GJB3, GJB2 and mtDNA 12s rRNA)were screened using a gene chip. Results Twenty women (6. 17G) have carried mutations. These included 11 (3.40%) carrying a GJB2 gene mutation, 7 (2. 16%) carrying a SLC26A4 gene mutation, 1 (0. 31%) simultaneously carrying GJB3 and GJB2 gene mutations, and 1 (0.31 %) carrying a mtDNA 12s rRNA gene mutation. Conclusion Women of child-bearing age have a high rate for carrying mutations of common deafness-related genes, among which 235delC in GJB2 was most common. Prenatal screening of couples with normal hearing is an effective way to prevent birth of affected children.
