NFRKB and Burkitt lymphoma: Another gene recurrently mutated in mnBLL-11q, NFRKB, locates at Chr.11q24, a region of chromosomal deletions and downregulated expression compared with BL (Figure 4a) which presumably affects transcriptional regulation by chromatin remodeling as a cofactor in the INO80 complex in parallel and in analogy to SWI/SNF, a chromatin remodeler frequently deregulated in BL [58].
