Myeloid differentiation primary response 88 (MYD88) encodes a cytosolic adapter protein that is frequently mutated in Waldenström macroglobulinemia (WM) and lymphoplasmacytic lymphoma (LPL). Approximately 90% of cases harbor a leucine to proline mutation at codon 265 (p.L265P, c.794T>C) in exon 5. Detection of MYD88 L265P can help establish a diagnosis of LPL in patients with typical histologic and flow cytometry findings as it rarely occurs in marginal zone lymphoma or chronic lymphocytic leukemia. MYD88 mutation status may also assist with risk stratification of IgM monoclonal gammopathy of undetermined significance or MGUS as patients who have the mutation are possibly at increased risk of progression to WM or LPL.
