Distribution of subjects included in the study and the corresponding CLL and CLL-like MBL clones, according to diagnosis.

*For multiclonal CLL and CLL-like MBL cases as well as for other B-CLPD cases other than CLL, only CLL-like clones were considered; the later B-CLPD cases included the following diagnoses: HCL, hairy cell leukemia; SMZL/MALT, splenic marginal zone B-cell lymphoma/extranodal marginal zone B-cell lymphoma of mucosa-associated lymphoid tissue lymphoma. CLL, chronic lymphocytic leukemia; MBL, monoclonal B-cell lymphocytosis; B-CLPD, B-cell chronic lymphoproliferative disorders.
†The number of clones per multiclonal case was of two in all diagnostic subgroups, except in three tri-clonal subjects corresponding to one CLL patient, one MBLhi case and one patient with a B-CLPD other than CLL.
