One observes a cluster of BL-resemblance which includes DHL-BCL2 and DHL-BCL6, mnBLL-11q, and partly, IRF4-breakL, as well as a DLBCL-like and an FL-like cluster with a certain overlap between them reflecting a transition range between DLBCL and transformed FL [54,55]. This evidence concerns the gene BCL6 and diffuse large B-cell lymphoma.
