For example, APC,[26,27] BMPR1A,[28,29] CDH1,[26,30] CSTB,[26,31] EPCAM,[27,29] MLH1,[28,29] MSH2,[26,27] MSH6,[27,32] STK11,[27,31] TP53,[30,31] and TPI1[27,33] could be promising candidate biomarkers, because these genes are relevant to GC occurrence. This evidence concerns the gene MLH1 and gastric cancer.
