Moreover, univariate Cox regression analysis showed that CYP1B1, FZD1, LRRK2, MELK, NCOA7, NOL3, P4HB, PML, PYCR1, SLC7A11, SOD2, and TLR6 were related to prognosis and could be potential risk factors for ccRCC patients (P < 0.05, Fig. 1C). The gene discussed is SOD2; the disease is nonpapillary renal cell carcinoma.
