MYD88 L265P Mutation pin


MYD88 L265P Mutation

Methodology: PCR

Clinical Significance:
The MYD88 L265P mutation is detected in ~90% of lymphoplasmacytic lymphoma (LPL)/Waldenstrom Macroglobulinemia (WM) cases, ~30% of activated/non-germinal center type diffuse large B cell lymphomas, ~40% of central nervous system lymphomas, and ~50% of IgM monoclonal gammopathies of undetermined significance (IgM-MGUS). Of note, the presence of an MYD88 L265P mutation has been associated with a higher risk progression in patients with IgM-MGUS. However, the MYD88 L265P mutation is not exclusively identified in these neoplasms and has been reported in other diagnostic entitites.
