Genes frequently mutated in DLBCL, FL and/or multiple myelomas (MM) such as BCL6 and BCL2 are found in or near spot K upregulated in healthy B cells and, to a lesser degree, in FL, and downregulated in BL and DLBCL (Additional file 1: Figure S5). Here, BCL2 is linked to diffuse large B-cell lymphoma.
