MYC expression was similarly distributed between GCB and ABC subtypes (P = 0.17) whereas BCL2 and BCL6 expression were significantly more common in the ABC and GCB subtypes, respectively (both P < 0.0001), in contrast to the association of their gene translocations with GCB and ABC subtype respectively. The gene discussed is MYC; the disease is aneurysmal bone cyst.
