Schmitz et al.32 classified DLBCL cases according to genetic findings into 4 categories, namely MCD (based on the cooccurrence of MYD88L265P and CD79B mutations), BN2 (based on bcl6 fusions and NOTCH2 mutations), N1 (based on NOTCH1 mutations) and the EZB group (based on EZH2 mutations and bcl2 translocations). Here, EZH2 is linked to diffuse large B-cell lymphoma.
