  • 简介:背景:研究表明神经肽S受体1(NPSR1)基因多态性与欧洲人群炎症性肠病(IBD)的遗传易感性相关,但尚无研究探讨两者在中国人群中的相关性。目的:探讨中国汉族人群中NPSR1基因多态性与IBD的关系。方法:收集武汉大学中南医院457例确诊IBD患者[溃疡性结肠炎(UC)组355例,克罗恩病(CD)组102例]和500名健康对照者,以PCR和测序技术分析NPSR1基因rs323922(C→G突变)、rs740347(G→C突变)位点多态性。结果:UC组与对照组间、CD组与对照组间rs323922、rs740347位点的基因型频率和等位基因频率差异均无统计学意义(P〉0.05)。基因型与IBD临床表型的相关性分析显示:①rs323922位点突变型CG基因型与男性CD(OR:0.441,95%CI:0.230~0.844)和结肠型CD(OR:0.425,95%CI:0.199~0.911)相关,为保护因素。②rs740347位点突变型CC基因型与CD早期发病(〈16岁)相关(OR:15.019,95%CI:2.634~86.470),突变型C等位基因与结肠型CD相关(OR:2.142,95%CI:1.709~4.294),两者均为危险因素。结论:NPSR1基因rs323922、rs740347位点多态性与中国汉族人群的IBD遗传易感性无关,但与IBD的某些临床表型有关。
