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, ITGA4 is linked to colorectal carcinoma.
