Characterization and strong risk association of to polymorphism and and their influence on mRNA expression in gastric cancer.

Background: Toll-like receptor-2 () is responsible for recognizing () and activating the immune response. Polymorphisms in may modulate gastric carcinogenesis.

Aim: To evaluate whether the (rs3804099) and - (rs111200466) polymorphisms contribute to gastric carcinogenesis in the Brazilian population, and to determine the influence of both polymorphisms and infection on mRNA expression.
