In the present study, a total of 14 immune checkpoint genes (PDCD1 (PD-1), CD274 (PD-L1), CTLA4, ADORA2A, C10orf54 (VISTA), HAVCR2 (TIM-3), ICOSLG, NT5E, CD27, IDO2, LAG3, TIGIT, TNFRSF18, and TNFRSF9) and nine m6A regulators (METTL14, WTAP, FTO, ALKBH5, YTHDF1, YTHDF2, YTHDF3, YTHDC1, and YTHDC2) were differentially expressed between the two groups of patients with ccRCC. Here, CD27 is linked to nonpapillary renal cell carcinoma.
