Diagnostic assays for discriminating Waldenstrom's Macroglobulinemia from IgM monoclonal gammopathy of undetermined significance are provided. The method comprises obtaining a biological sample from a subject in need thereof, performing an allele-specific polymerase chain reaction assay to determine in the biological sample a level of a transcript comprising a mutation at position 38182641 in chromosome 3p22.2, and providing a report indicating whether delta C.sub.T value of the biological sample is less than a reference value, wherein the subject has Waldenstrom's Macroglobulinemia if the delta C.sub.T value is less than the reference value.
