摘  要:目的:研究白细胞介素1β(IL-1β)启动子-511位点C/T单核苷酸多态性(SNP)在西藏藏族健康人群中的分布特点。方法:采用聚合酶链反应-限制性片段长度多态性(PCR-RFLP)的方法,对144名西藏拉萨市藏族人群IL-1β-511位点SNP进行检测,计算其基因型频率和等位基因频率。结果:西藏拉萨市藏族人群IL-1β-511点基因型以CT杂合子型最为多见(52.72%),TT纯合子型次之(36.11%),CC纯合子型较少(11.11%);其等位基因分布也是以T等位基因最为多见(62.50%),其次为C等位基因(37.50%)。西藏藏族人群的等位基因频率分布与奥地利人、非洲黑人、非洲白人、日本人差异均有统计学意义。结论:西藏拉萨市藏族人群中IL-1^-511位点基因型以CT和TT型为主,等位基因以T为主,其SNP分布与其他种族之间存在差异。Objective: To study the distribution of the fifth exon region-511 C/T polymorphism of interleukin-1/3 gene in Tibetan populations. Methods: Using PCR-RFLP method, the polymorphism at position-511 of IL-lβ exon 5 in 144 Tibetan populations was detected, and the genotype and allele frequencies were calculated and analyzed. Results: In Tibetan populations, the most frequent genotype was CT (52.72%), and the second was TT (36.11%), the last was CC (11.11%) the most frequent allele was T (62.50%), then was C (37.50%). The polymorphism of IL-113-511 in Tibetan population was significantly different compared with Austrian, African American, White and Japanese. Conclusion: In Tibetan population the most frequency genotypes were CT and CC, and the most frequency allele was T of IL-1β-511, for the SNP distribution of IL- 1β-511 was different between different populations.
