BCL2 and diffuse large B-cell lymphoma: MCD was characterized by mutations in MYD88L265P and CD79B, while N1 presented mutations in NOTCH1. In both subtypes, most cases were ABC-DLBCL, and had a worse prognosis than BN2, based on BCL6 fusions and NOTCH2 mutations, and EZB, which was characterized by BCL2 translocations and mutations in the EZH2 gene [28].
