As revealed by the survival heat map analysis, SLC12A1-A7, SLC34A1 and SLC34A3 were closely related to the OS of ccRCC, whereas SLC12A2/A4/A6/A7 and SLC34A1/A3 were closely related to DFS in ccRCC, which were significantly correlated with clinical stage, OS and DFS. Here, SLC34A3 is linked to nonpapillary renal cell carcinoma.
