Another study found that mutations in the KRAS proto‐oncogene (KRAS) were more commonly detected in colon tumors than rectal tumors, and that the number of mutations detected was higher in colon tumors when compared to rectal tumors, further strengthening the theory that the pathways to carcinogenesis differ for colon and rectal tumors.41 The gene discussed is KRAS; the disease is colonic neoplasm.
