KLF2 and diffuse large B-cell lymphoma: Multiple KLF2 mutations (2–5) have been described previously in eleven patients with HLC-c (n = 1), extra-nodal marginal zone lymphoma (=1), Burkitt lymphoma (n = 1), SMZL (n = 1) and diffuse large B cell lymphoma (n = 7), and in most cases, the KLF2 mutations were located on separated alleles [26].
