For the OS rate analysis of the 23 genes, GEPIA and ULCAN indicated that 10 genes (EPB41L4B, CCND1, GGT1, CGNL1, CYSLTR1, PLAUR, UGT3A1, PROM2, MUC12, and PCK1) may play a key role in the OS rate in patients with ccRCC (P < 0.05, Figure 6, Supplementary Figure 2). This evidence concerns the gene GGT1 and nonpapillary renal cell carcinoma.
