We found that the PHL and DLBCL groups shared 5 majority driver genes (Figure 3A), namely, TP53, GNA13, KLHL6, H1-4, and MYD88, and the DLBCL-liver and DLBCL groups shared 7 majority driver genes, namely, BTG2, KMT2C, MEF2B, TET2, CARD11, CREBBP, and EZH2; 27.8% (5/18) of the genes in PHL were mutated in DLBCL. This evidence concerns the gene EZH2 and diffuse large B-cell lymphoma.
