Previous studies using TCGA data and other cohorts have shown that BAP1 mutation, but not PBRM1 mutation, correlates with poor survival in ccRCC and these correlations were confirmed in a mixed cohort of ccRCC and PRCC TCGA tumors (Chen et al., 2016; Hakimi et al., 2013; Kapur et al., 2013). The gene discussed is BAP1; the disease is nonpapillary renal cell carcinoma.
