摘要: 目的: 探讨中国华东地区汉族人群细胞色素P450 3A4 基因的基因型差异。方法: 采用 RT-PCR与DNA 测序技术相结合的方法对来自华东地区的6份汉族成人肝组织 P450 3A4基因的cD-NA 进行了扩增与序列分析 。结果: 本研究从6份汉族人肝组织中首次检测到了一种新的基因型,该基因型存在三处氨基酸突变和一处核苷酸缺失, 即第71位氨基酸发生V(GTG)→A(GCG) 突变;第225位氨基酸发生V(GTC)→I(AIC)的突变;第393位氨基酸发生W(TGG)→V(GTG) 突变;第671~673位核苷酸CAG发生缺失。结论: 本研究首次发现中国华东地区汉族人群存在一种CYP3A4 新基因型。

Abstract: AIM: To explore the genotype differ-ence of CYP3A4 gene from Chinese Han population in East China .METHODS: The CYP3A4 gene cDNA of six samples of adult human liver tissues from Chinese Han population were amplified and identified by RT-PCR and DNA sequencing .RESULTS: One new geno-type of CYP3A4 was identified from six samples.There are three amino acids mutations, i .e .V (GTG) →A (GCG) at 71st amino acid site ;V(GTC) →I(AIC) at 225th amino acid site;W(TGG) →V(GTG) at 393rd amino acid site, and three nucleotide acids lack, i .e . CAG from 671st to 673rd nucleotide acid site. CONCLUSION: one new genotype of CYP3A4 gene is dis-covered for the first time from Chinese Han population in East China.
