摘要
目的探讨IL-10基因-1082G/A的基因多态性与肺结核易感性的关系。方法通过家系病例对照设计,用聚合酶联反应-限制性片段长度多态性检测IL-10基因rs1800896位点,分析基因型和等位基因的频率在病例家系人群和对照家系人群及其一级亲属中的分布差异;采用logistic回归模型进行所研究基因的遗传变异与结核病发病风险的关联性分析。结果 180例样本中病例家系组有28组,共89人,患病人数为41人,一级亲属患病23人;对照家系组有35组,共91人。对于IL-10基因rs1800896位点,与A等位基因携带者相比,携带G等位基因的个体结核病发病风险显著增高(OR=4.48,95%CI=1.14-17.61)。结论 IL-10基因rs1800896位点可能为结核病的易感位点,与A等位基因携带者相比,携带G等位基因的个体结核病发病风险显著增高。
Objective To investigate the relationship between gene polymorphism of IL-10 gene-1082 G/A and susceptibility to tuberculosis.Methods Case-control family study was conducted,and the data was collected from Guangdong province.PCR-RFLP technique was used to detect the G/A polymorphism in the rs1800896 locus of IL-10 gene,and to analyze the distribution of genotypes and allele frequencies in case families and control families and their first-degree relatives.Logistic Regression Model was used to analyze the genetic variation and the risk of tuberculosis.Results A sample of 180 people was included.There were 28 cases in the family group(89 people),including 41 patients and 23 first-degree relatives and 35 cases in control family group(91 people).IL-10 gene loci rs1800896 genotype distribution was in line with Hardy-Weinberg law of genetic equilibrium(P>0.05),with good mass.The rs1800896 of the IL-10 gene may be a susceptibility factor to tuberculosis.Compared with the A allele of IL-10 gene rs1800896 carrier,the G allele was significantly over-represented in case groups(OR=4.48,95%CI=1.14-17.61),and the dominant model(AG+GG vs AA)was also associated with a high risk of tuberculosis(OR=4.48,95%CI=1.14-17.61).Conclusion The IL-10 gene rs1800896 may be a susceptible site to tuberculosis.Compared with the A allele carrier,the risk of tuberculosis in individuals carrying the G allele is significantly increased.
