MYD88 Mutation Analysis
Also known as: Myeloid Differentiation Primary Response 88
Use
MYD88 mutation is the most common genetic abnormality in the activated B-cell-like (ABC) subtype of diffuse large B-cell lymphoma (DLBCL), detected in 40% of cases. Mutations are rare in the germinal center B-cell-like (GCB) subtype, so mutation analysis can be useful to differentiate between the ABC and GCB subtypes. The L265P mutation is present in >90% of Waldenstrom's macroglobulinemia (WM) and has been associated with increased risk of progression to WM in IgM MGUS patients. MYD88 is also implicated in susceptibility to BTK inhibitors in the treatment of B-cell neoplasms.
Special Instructions
Use cold pack for transport, making sure cold pack is not in direct contact with specimen. For fresh samples: refrigerate before shipping and ship same day as drawn whenever possible. Do not freeze. Please select extract & hold - DNA if specimen hold service is desired. NYS clients please provide date and time of collection.
Limitations
Mutations are rare in the germinal center B-cell-like (GCB) subtype, indicating limitations in detection utility for these cases. Zinc fixatives for FFPE samples should not be used as they may affect results. Accurate specimen labeling is crucial.
