FHIT and colonic neoplasm: Three regions: 3p14.2 (deletion), 9p21.2q21.31 (amplification), and 20q13.12 (amplification) were commonly found in HN4 and HN31 as the same cluster in our analysis, and five genes (FHIT, MMP9, GNA14, GNAQ, and PSAT1) were involved in tumorigenesis in lung cancer and colon cancer [50, 63, 78–80].
