Finally, we selected nine genes that were highly associated with prognosis in stage III ccRCC patients (ATP6V1C2, PCSK1N, PREX1, ANK3, HLA-DRA, SELENBP1, TYRP1, GABRA2, and SERPINA5; see detailed information in Supplementary Table 2). The gene discussed is GABRA2; the disease is nonpapillary renal cell carcinoma.
