On the other hand, a study carried out in the Chinese population identified that the SNP rs12904 located in the miR-200c binding site of the EFNA1 gene is associated with an increased risk of developing gastric cancer, with the rs12904 AA genotype correlating with a higher expression of EFNA1 in gastric tissues, although it has no effect on the expression of the miRNA [75]. This evidence concerns the gene EFNA1 and gastric cancer.
