Several genes such as WIF1, VIM, TFPI2, SFRP2, RASSF2A, NDRG4, MGMT, MLH1, MINT31, MINT1, KRAS, ITGA4, IRF8, ID4, HLTF, GSTP1, GATA4, ESR1, CXCL21, CRBP1, CDH13, CDKN2A, CDH1, BMP3, ATM, and APC have all been studied for CRC diagnosis (Park et al., 2017). Here, TFPI2 is linked to colorectal carcinoma.
