Despite we were unable to validate their association with ccRCC mortality, there were other prioritized genes among the top ranked that are interesting candidates for further study, namely GPR155, INPP5K, KRT7, CYP4B1 and the mucin encoding genes (MUC5B, MUC12, and MUC16). This evidence concerns the gene MUC16 and nonpapillary renal cell carcinoma.
