AQP1, a Colton blood group antigen system gene, was reported to be associated with poor prognosis in colon cancer and lung adenocarcinoma [25,26], while seven of the fifteen genes were reported to be prognostic in one tumor type (GCNT2, FUT7, FUT3, FUT2, DARC, CR1 and BSG, Figure 1C). The gene discussed is ACKR1; the disease is lung adenocarcinoma.
