中文摘要:
      目的 调查中国汉族人群中人类免疫缺陷病毒1(HIV-1)感染相关的CCR5△32、CCR2-64I和SDF1-3'A等位基因突变频率和多态性的特点。方法 以1 251例汉族人群为研究对象,应用PCR、PCR/RFLP(聚合酶链反应/限制性片段长度多态性分析)和DNA直接测序等方法进行检测,并用统计学方法进行分析。结果 发现中国汉族人群中存在CCR5△32等位基因突变(均为杂合子基因型),突变频率为0.001 19,和西欧及美国白人相比,中国人群中CCR5△32基因突变频率极低,而CCR2-64I和SDF1-3'A基因突变频率相对较高,分别为0.200 23和0.287 23。结论 中国汉族人群的CCR5△32、CCR2-64I和SDF1-3'A等位基因的突变和多态性特点,具有一定的代表性。由于CCR5△32突变率低,中国汉族人群对性接触传播的HIV-1病毒(R5)株可能有较大的遗传易感性。
英文摘要:
      Objective To study the frequency and polymorphism of three mutations (CCR5△32,CCR2-64I and SDF1-3'A alleles) conferring resistance to determined HIV-1/AIDS in the indigenous Han population in China. Methods The study population included 1 267 subjects, of which consisted 98.7% (1 251/1 267) Han people. The genotypes of the three mutations were respectively, detected by polymerase chain reaction(PCR) for CCR5△32 mutation, or by PCR/RFLP(restriction fragment length polymorphism) assay with the digestion of restriction endonuclease Bsa BI and Msp I for CCR2-64I and SDF1-3'A mutations. DNA sequencing was empolyed to confirm the accracy of PCR or PCR/RFLP products. Results The frequency of the mutant alleles were:0.001 19 for CCR5△32;0.200 23 for CCR2-64I, and 0.287 23 for SDF1-3'A. The three heterozygous CCR5-wt/△32 mutants were identified and no homozygotes were detected in indigenous Han population. The frequencies of CCR2-64I and SDF1-3'A alleles in China were higher than those of Caucasians descents in the USA and Europe. ConclusionOur data was the first findings on the frequency and polymorphism of CCR5△32, CCR2-64I and SDF1-3'A alleles in indigenous Han population in China which implied that the indigenous Han people might have a higher genetic susceptibility to the infection of sexually transmitted HIV-1 (R-5) strain. Further study is needed to clarify the significance of higher frequency of CCR2-64I and SDF1-3'A alleles in Han population.
