CLL/SLL was the first entity to discriminate in the model, with 5 differentially upregulated genes (BTLA, ARHGAP44, ZBTB24, CLNK, and CD200), and was followed by cMCL with 6 markers, FL with 8 markers, nnMCL with 4 markers, MZL with 6 markers, and LPL/WM with 6 markers. This evidence concerns the gene ZBTB24 and B-cell chronic lymphocytic leukemia.
