In colorectal cancer, reduced FABP1 expression was strikingly linked to histologic grade, microsatellite instability (MSI), and tumor location in the right side of the colon (p < 0.0001 each), and absence of BRAF V600E mutations (p = 0.001) but was unrelated to pT and pN status or RAS mutation status. The gene discussed is FABP1; the disease is colorectal cancer.
