In pleural and peritoneal mesothelioma, co-occurring alterations occurred on the same chromosome or in close proximity for PBRM1–BAP1 (both 3p21) and SETD2–BAP1 (both 3p21), which was observed in the TCGA cohort but not in the recent publication by Zauderer and colleagues [15]. This evidence concerns the gene SETD2 and peritoneal mesothelioma.
