In the rest of the neoplasms studied, including additional ALL groups and mature B-cell neoplasms such as CLL, FL, iMCL, DLBCL, primary mediastinal B-cell lymphoma and BL, SOX11 was either not expressed or expressed at very low levels in a small subset of the cases (Figure 1A–1B). This evidence concerns the gene SOX11 and diffuse large B-cell lymphoma.
