In this study, “mutBL” pattern included mutations in BL-associated genes (ID3/TCF3, CCND3 and c-MYC), while “mutDL” pattern included mutations in DLBCL-associated genes (BCL2, enhancer of Zeste homolog 2 (EZH2), cyclic adenosine 3,5-monophosphate response element-binding protein binding protein (CREBBP), E1A binding protein P300 (EP300), myocyte enhancer factor 2B (MEF2B) and serum/glucocorticoid regulated kinase 1(SGK1)). The gene discussed is MEF2B; the disease is diffuse large B-cell lymphoma.
