MM is a malignant tumor of plasma cells usually arising in the bone marrow and characterized by diffuse involvement of the skeletal system, hyperglobulinemia, Bence-Jones proteinuria and anemia. Complications of multiple myeloma are bone pain, hypercalcemia, renal failure and spinal cord compression. The aberrant antibodies that are produced lead to impaired humoral immunity and patients have a high prevalence of infection. Amyloidosis may develop in some patients. Multiple myeloma is part of a spectrum of diseases ranging from monoclonal gammopathy of unknown significance (MGUS) to plasma cell leukemia. Note=A chromosomal aberration involving IGHG1 is found in multiple myeloma. Translocation t(11;14)(q13;q32) with the IgH locus. Translocation t(11;14)(q13;q32) with CCND1; translocation t(4;14)(p16.3;q32.3) with FGFR3; translocation t(6;14)(p25;q32) with IRF4. Evolutionary Conservation Check, as determined by ConSurfDB.

Publication Abstract from PubMed Antibodies contain a conserved glycosylation site that has emerged as a target for the modulation of antibody effector functions. The crystal structure of a biosynthetic intermediate of human IgG1, bearing immature oligomannose-type glycans and reported to display increased antibody-dependent cellular cytotoxicity, demonstrates that glycan engineering can bias the Fc to an open conformation primed for receptor binding.
