In line with their GC origin, Burkitt lymphomas (BL), follicular lymphomas (FL) and diffuse large B cell lymphomas (DLBCL) are GC-experienced, as evidenced by somatic hypermutation (SHM)-mediated mutagenesis within their BCR variable regions – an irreversible marker of GC passage (5–8). Here, BCR is linked to Burkitt lymphoma.
