However, in follicular lymphoma (FL) and diffuse large B cell lymphoma (DLBCL), CREBBP mutations disable its acetylation and result in unopposed deacetylation by the BCL6-SMRT-HDAC3 complex at enhancers of B cell signal transduction and immune response genes, thus promoting lymphomagenesis [72, 73]. This evidence concerns the gene BCL6 and diffuse large B-cell lymphoma.
