Confirming previous reports, we found mutual exclusive mutations between IDH1 and IDH2 (Yan et al., 2009), between IDH2 and TET2 (Gaidzik et al., 2012), between TET2 and WT1 (Wang et al., 2015), and between IDH1-EGFR (Agnihotri et al., 2014) in AML and LGG (Figures 1D,E). This evidence concerns the gene WT1 and acute myeloid leukemia.
