Kaplan-Meier survival curve analysis showed that low expression of NOS1, ALAD, ACADM, SCD5, and CA4 genes and high expression of ALDH3B2, ITPKA, IMPDH1, FADS2, ACHE, and HK3 genes was associated with shorter overall survival of ccRCC patients. This evidence concerns the gene NOS1 and nonpapillary renal cell carcinoma.
