VEGFA and gastric cancer: Recently, Ke Q et al [21] found that none of four potentially functional SNPs (-2578C>A, -1498T>C, -634G>C, and +936C>T) of the VEGF gene or their haplotypes achieved a significant difference in their distributions between gastric cancer cases and controls in a Chinese population, whereas in a Greek study of the association between these four potentially functional SNPs in VEGF and gastric cancer risk in 100 cases and 100 controls [38], it was found that the -634CC variant genotype was associated with an increased the risk of gastric cancer with a marginal significance.
