The ROC analysis revealed that the expression of six of the seven analyzed genes (CA9, NDUFA4L2, EGLN3, BHLHE41, VWF, and ANGPTL4) showed a statistically significant relationship (p = 0.001–0.002) with the survival of patients with ccRCC. The gene discussed is CA9; the disease is nonpapillary renal cell carcinoma.
