摘　　要：目的研究干扰素-γ(interferon gamma,IFN-γ)第三内含子区+2707位点单核苷酸多态性与多发性硬化(multiple sclerosis,MS)易感性的相关性。方法选取河北医科大学第二医院住院MS患者58例,正常对照40例,采用聚合酶链反应-限制性片段长度多态性(PCR-RFLP)的方法对INF-γ第三内含子+2707位点单核苷酸多态性进行分析,经统计学处理,研究其与MS易感性的相关性。结果 IFN-γ+2707位点MS组与健康对照组基因型分布的比较差异没有统计学意义(P>0.05);MS组IFN-γ+2707位点A及G等位基因频率与健康对照组比较均没有统计学意义(P>0.05)。结论 IFN-γ第三内含子区+2707位点基因多态性与MS的遗传易感性不相关。Objective To study the association between polymorphism in the third intron of IFN-γgene and the susceptibility to MS. Methods A population-based case-control study was carried out. 58 patients with MS and 40 healthy controls were interviewed. Meanwhile, the genetic polymorphism of INF-γ intron Ⅲ ＋2707A allele was detected using polymerase chain reaction-restriction fragment length polymorphism. Results No significant difference of genotypes and site frequencies of INF-γ intron Ⅲ＋2707 existed in MS group compared with in the control group（P〉0.05）. Conclusion The INF-γ intron Ⅲ （＋2707） genepolymorphism might not be associated with MS genetic susceptibility.
