Of these, 23 markers (BAD, BAX, CDH1, CDK6, CDKN1A, CDKN1B, CTNNB1, EGF, EGFR, FN1, HRAS, IRS2, KRAS, MAPK3, MDM2, MMP2, PDGFC, PIK3CA, PIK3R3, SMAD4, TGFB1, TGFBR2, TLR2) have been covered in the literature very widely, and multiple publications link these, largely through mutations, to many different cancers, including CRC. This evidence concerns the gene CDK6 and cancer.
