The high mutation rate of PBRM1 in ccRCC has been confirmed by multiple studies, together with mutations in other genes such as BAP1, SETD2, KDM5C/JARID1C, PTEN and UTX (Dalgliesh et al., 2010; Guo et al., 2012; Peña-Llopis et al., 2012; Cancer Genome Atlas Research Network, 2013; Sato et al., 2013). The gene discussed is PBRM1; the disease is nonpapillary renal cell carcinoma.
