In addition, ABC DLBCL have common gains affecting chromosome 3, which could might contribute to immune escape (FOXP1, 3p14), NF-κB pathway activation (NFKBIZ, 3q12) and B cell differentiation arrest (BCL6, 3q27) (4, 7, 13, 15, 17, 27, 30–32, 34, 36, 38, 40, 48, 49, 52–54). This evidence concerns the gene NFKB1 and aneurysmal bone cyst.
