Two of these genes, branched‐chain amino acid transaminase 1 (BCAT1) and ikaros family zinc finger protein 1 (IKZF1) may play an important functional role in maintaining a healthy colorectal tissue 20, 21, and both BCAT1 and IKZF1 appear to be involved in tumor growth and invasiveness 21, 22, 23, 24, 25, 26. This evidence concerns the gene BCAT1 and neoplasm.
