M-protein
M-protein in the glossary for Waldenström's macroglobulinemia
An abnormal antibody (immunoglobulin) or fragment thereof, produced in excess by abnormal monoclonal proliferation of plasma cells.
M-proteins are immunoglobulins produced in excess by an abnormal clonal proliferation of B-cells or plasma cells. Excessive M-protein production is characteristic of a group of disorders termed monoclonal gammopathies, paraproteinaemias, or plasma cell dyscrasias. These disorders comprise a spectrum of premalignant and malignant hematological conditions and include MGUS, Waldenström’s macroglobulinemia and multiple myeloma.1
