MYD88 L265P mutations are present in the majority of LPL cases include Waldenström’s macroglobulinemia,
Mutations are also detected in a low percentage of chronic lymphocytic leukemia (CLL) and diffuse large B-cell lymphoma (DLBCL) cases.
Detection of MYD88 L265P mutation can aid in differentiation between LPL and other low - grade B-cell lymphoproliferative disorders which may appear similar to LPL. Mutation may be crucial for treatment decisions. LPL may be treated with chemotherapy or rituximab.
