IG::MYC translocation in BL primary cases according to SOX11 expression levels and EBV status. (A-B) Frequency of IGH::MYC, IGK::MYC, and IGL::MYC translocations (A), and frequency of translocations generated by CSR, SHM, or V(D)J processes (B), in the total group of EBV⁺, EBV⁻/SOX11⁻, and EBV⁻/SOX11⁺ BLs. Fisher exact test was performed to evaluate differences between group frequencies.
