Single nucleotide polymorphisms in miRNA binding sites, which are located in mRNA 3' untranslated regions (3'-UTRs), were recently found to influence microRNA-target interactions. Specifically, such polymorphisms can modulatebinding affinity or create or destroy miRNA-binding sites; such variants have also been found to be associated with cancer risk. In this study, we explored the effect of a functional variant at the miR-214 binding site in the methylenetetrahydrofolate reductase gene (rs114673809) on gastric cancer (GC) risk in a hospital-based case-control study in a Chinese Han population.
