Molecular characteristicsof the BCR of CLL-like MBLlo, MBLhi and CLL B-cell clones.

Results expressed as number of B-cell clones from all clones in the corresponding group (percentage) or or as *median (range). Statistically significant differences were found between aMBLhi vs CLL, bMBLlo vs CLL, cMBLlo vs MBLhi, d MBLlo plus MBLhi vs CLL and eMBLlo vs MBLhi plus CLL; NS, no statistically significant differences observed (P≥0.05);BCR, B-cell receptor; CLL, chronic lymphocytic leukemia; MBL, monoclonal B-cell lymphocytosis; aa, aminoacids; HCDR3,heavy chain complementarity-determining region 3.
