Multiple myeloma (MM) is a malignancy of plasma cells that manifests clinically as hypercalcaemia, renal impairment, anaemia and/or bone disease. MM is preceded by the precursor syndromes monoclonal gammopathy of undetermined significance (MGUS) and smouldering multiple myeloma (SMM).

Primary genetic alterations that underlie MGUS, SMM and MM are chromosomal translocations that involve IGH (encoding immunoglobulin heavy-chains) and hyperdiploidy. Further genetic aberrations, such as copy number alterations, complex structural events and other mutations are involved in disease progression and, in some cases, are associated with treatment resistance.

This poster from Nature Reviews Disease Primers illustrates the process of plasma cell development and summarizes the genetic alterations that are associated with development and progression of MM. This poster also highlights the frequencies of these genetic alterations.
