Overview of the expression of BCMA in plasma cell dyscrasias. Scatterplot depicted the BCMA expression in all the plasma cell dyscrasias according to BCMA positive rate and MFI. It was divided into four quadrants by median lines. Different colors of the dots indicated different populations: MM (purple), AL (green), MGUS (yellow), POEMS syndrome (red), MGRS (blue). The BCMA positive rate ranged from 0.2% to 99.9%, with a median of 87.1%, and BCMA MFI ranged from 109 to 48586 with a median of 1181. Abbreviations: BCMA, B cell maturation antigen; MFI, mean fluorescence intensity; MM, multiple myeloma; AL, systemic light chain amyloidosis; MGUS, monoclonal gammopathy of undetermined significance; MGRS, monoclonal gammopathy of renal significance.
