IKZF1 and diffuse large B-cell lymphoma: Similar intragenic distributions of integrations have previously been described for the tumor suppressor Ikzf1 which is mutated or deleted in both B and T-ALL22,23 (Supplementary Fig. 11h), and this pattern is also observed for the tumor suppressors Ikzf3 and Ebf1 (Supplementary Figures 11i, j), both of which have inactivating mutations in FL and DLBCL but more typically B-ALL22,24–26.
