ID1 and cancer: We narrowed down the list to ID1, BCL2L1, TPX2, HCK, PLAG2, POFUT1, DNMT3B, E2F1, and E2F6. It is worth noting that none of these genes are cataloged as oncogenes according to the Catalogue of Somatic Mutations in Cancer Cancer Gene Census (https://cancer.sanger.ac.uk/census), indicating that despite this evidence, their roles in cancer are still in need of further research.
