Overall survival analysis of risk scoring genes revealed that ccRCC patients with high expression of FLRT3, ATP1A1, PDK4, and KCNJ15 presented better prognosis, but patients with high SAA expression presented worse prognosis (Supplementary Figure 5), which was consistent with the positive and negative risk coefficients in the risk scoring model. The gene discussed is FLRT3; the disease is nonpapillary renal cell carcinoma.
