MYC and diffuse large B-cell lymphoma: As the number of B‐ALL/LBLs investigated in the present study was small, we compared the mutation load of a common set of SHM target genes between our TdT‐positive LBCLs (19 DLBCL/HGBCL‐MYC/BCL2, six DLBCL/HGBCL‐NOS) and a larger cohort of B‐ALL cases (n = 1716) from a previous study [14].
