CCND3 and Burkitt lymphoma: Of the remaining 13 cases, 11 had variants affecting other genes known to be mutated in BL, such as GNA13, FOXO1, THOA, MYC, ARID1A, and TP53. Mutations affecting ID3/TCF3/CCND3 were significantly more likely in EBV-negative sBL, irrespective of age (p = 0.0088), while mutations of G protein subunit alpha 13 (GNA13; p = 0.0368) and forkhead box O1 (FOXO1; p = 0.0044) were significantly more likely in EBV-positive sBL [9].
