As shown in Figures 6, genetic alterations in SLC22A6, SLC22A7, SLC22A13, SLC25A4, SLC34A1, and SLC44A4 occurred in 42.2% of ccRCC patients, with SLC22A6 in 3%, SLC22A7 in 2.2%, SLC22A13 in 12%, SLC25A4 in 3%, SLC34A1 in 18%, and SLC44A4 in 4%. This evidence concerns the gene SLC22A7 and nonpapillary renal cell carcinoma.
