重庆地区汉族CD14启动子区多态性分析

Polymorphism in CD14 promoter region in Han population in Chongqing

目的 调查CD14 ( 2 60 )多态性在重庆地区汉族中的分布特征 ,及检验该随机样本遗传学研究的可靠性。方法 对 110名重庆汉族个体 ,采用降落式PCR和限制性片段长度多态性法 (RFLP)进行基因型分析。结果 重庆地区汉族CD14 ( 2 60 )多态性TT、TC、CC 3种基因型频率分别为 43 6%、3 9 1%和 17 3 %;样本分布符合Hardy Weinberg平衡。结论 重庆汉族CD14 ( 2 60 )多态性基因型分布特征与白种人存在明显差异。样本为H W平衡群体 。

Objective To investigate the distribution of CD14C ( 260)T single nucleotide polymorphism (SNP) in the Han population in Chongqing and to test the reliability with this random sample in genetic research. Methods Single round Touchdown PCR (TD PCR) and restriction fragment length polymorphism (RFLP) method were used for genotyping in 110 people from the Han population in Chongqing. Results Frequencies of TT, CT, and CC genotypes were 43 6%, 39 1%, and 17 3%, respectively. The sample distribution was accorded with Hardy Weinberg principle. Conclusion CD14C( 260)T SNP was found in the Han population in Chongqing, and the distribution of alleles was significantly different from that in white population. The sample from an H W equilibrium population can be used in the association study of the systematic inflammatory reaction in the Han population in Chongqing.
