Core Tip
Core tip: There is currently a need for genetic markers to identify individuals at risk for developing gastric cancer. In this study, we describe one such marker, a G-197A polymorphism in the interleukin-17A (IL-17A) promoter. Within our study population, individuals who carry the G-197A polymorphism in the IL-17A promoter region may be at a significantly greater risk of developing gastric cancer. Importantly, the presence of this polymorphism alone was sufficient to increase risk of gastric cancer development.
