Schmitz et al. [47] identified four prominent genetic subtypes in DLBCL, termed MCD (co-occurrence of MYD88L265P and CD79B mutations), BN2 (BCL6 fusions and NOTCH2 mutations), N1 (NOTCH1 mutations), and EZB (EZH2 mutations and BCL2 translocations). This evidence concerns the gene BCL6 and diffuse large B-cell lymphoma.
