This study [83] demonstrated that BLL-11q lacks ID3, TCF3, and CCND3 mutations, which are frequently found in BL, and shows, by contrast, frequent gains of 12q12-q21.1 and losses of 6q12.1-q21, which can be seen in 15% of DLBCL and IRF4-translocated lymphomas [86]. The gene discussed is TCF3; the disease is Burkitt lymphoma.
