</strong>Gastric cancer is the most common cancers worldwide. The <em>survivin</em> gene which encodes an apoptosis protein inhibitor plays an important role in maintenance and integrity of the gastric mucosa. The gene is necessary for the normal physiologic function of the stomach, but its expression increases in gastric cancer. Regarding with the role of polymorphisms of the promoter region in genes expression, this study was done to determine the association of single- nucleotide polymorphism (rs9904341) -31C/G in promoter <em>survivin</em> gene with risk of gastric cancers.<br> <strong>Methods: </strong>In this case-control study, 101 patients with gastric cancer and 101 matched age and gender healthy subjects as the control were examined by PCR-RFLP technique.<br> <strong>Results: </strong>Genotype CC was significantly increased the risk of gastric cancer up to 2.4 folds (95% CI=1.03&ndash;5.61, P<0.04) and allele C, as risk allele, significantly increased the risk of gastric cancer up to 1.5 folds (95% CI=1.02&ndash;2.30, P<0.03). Also, CC + GC genotypes significantly increased the risk of diffuse type of gastric cancer by 4.4-fold (95% CI=1.30-15.10, OR=4.4, P<0.01).<br> <strong>Conclusion: </strong>This study showed that single- nucleotide polymorphism (rs9904341) -31C/G in promoter <em>survivin</em> gene significantly increase the risk of gastric cancers. سرطان معده , چندشکلی تک‌نوکلئوتیدی , rs9904341 , ژن Survivin Gastric cancer, Survivin gene, Single nucleotide polymorphism- rs9904341 32 37 http://goums.ac.ir/journal/browse.php?a_code=A-10-1-989&slc_lang=fa&sid=1 Z Bagheri زهرا باقری اصلی چوبری 5900319475328460049364 5900319475328460049364 No M.Sc in Genetics, Department of Biology, Faculty of Basic Sciences, Sharekord Branch, Islamic Azad University, Shahrekord, Iran کارشناسی ارشد ژنتیک، گروه زیست شناسی، دانشکده علوم پایه، واحد شهرکرد، دانشگاه آزاد اسلامی، شهرکرد، ایران P Mohamadynejad پریسا محمدی نژاد parisamohamadynejad@yahoo.com 5900319475328460049365 5900319475328460049365 Yes Ph.D in Genetics, Assistant Professor, Department of Biology, Faculty of Basic Sciences, Sharekord Branch, Islamic Azad University, Shahrekord, Iran استادیار، گروه زیست شناسی، دانشکده علوم پایه، واحد شهرکرد، دانشگاه آزاد اسلامی، شهرکرد، ایران M Moghanibashi محمدمهدی مغنی باشی منصوریه 5900319475328460049366 5900319475328460049366 No Ph.D in Genetics, Assistant Professor, Department of Genetic, School of Medicine, Kazerun Branch, Islamic Azad University, Kazerun, Shiraz, Iran استادیار، گروه ژنتیک، دانشکده پزشکی، واحد کازرون، دانشگاه آزاد اسلامی، کازرون، ایران
