TCF7L2 and gastric cancer: In a study of 129 GC‐ biopsies from Venezuelan patients, the TCF7L2 rs7903146 TT genotype was associated under the recessive model with GC‐ risk (OR = 3.11; 95% CI: 1.22–7.92; p = 0.017) and poorly differentiated GC (OR = 3.65; 95% CI: 1.25–10.62; p = 0.018), and the rs7903146 T allele conferred a significantly increased risk of moderate/well‐differentiated GC under the dominant model (OR = 2.55; 95% CI: 1.35–4.80; p = 0.004); these findings should be replicated in a larger data set.
