BCL2 and diffuse large B-cell lymphoma: Recent analyses have suggested new taxonomies of DLBCL on the basis of genetic characteristics.5,6 Whereas Schmitz et al6 used a data set focused strongly on the ABC and UNC COO groups, where the MHG group would be under-represented, Chapuy et al5 commented on the genetic complexity of MYC and BCL2 dysregulation that is represented in more than one of their clusters.
