BIRC5 and nonpapillary renal cell carcinoma: We then assessed the diagnostic values of the risk genes for OS (PRKCQ, BID, BAG1, BIRC5, and ATG16L2) and DFS (EIF4EBP1, BAG1, ATG9B, and BIRC5) using ROC curve analysis of gene expression data from 535 ccRCC patients from the TCGA database and 28 healthy individuals from the Genotype-Tissue Expression project.
