The results indicated that the polymorphisms in iNOS gene (C150T(Ser(608) Leu) polymorphism and polymorphic (CCTTT)n repeats) had no association with cancer risk for all genetic models.
The aim of this study was to evaluate the association of NOS2 polymorphisms Ser608Leu (rs2297518) in exon 16, -954G/C and -1173C/T, both in the promoter region, with gastric cancer and chronic gastritis and the association of cancer with risk factors such as smoking, alcohol intake and H. pylori infection.
