NPM1 MRD Analysis
Also known as: NPM1 Minimal Residual Disease
Use
Mutation at exon 12 of nucleophosmin 1 (NPM1) gene is a predictor of favorable prognosis in AML with intermediate-risk and associated with good response to induction chemotherapy; if there is no mutation in FLT3. Mutations in the NPM1 gene also are frequently associated with normal karyotype in adult and pediatric acute myeloid leukemia (AML). The ratio of the mutant peak to total can be used to monitor disease and response to therapy.
Special Instructions
Not provided.
Limitations
Testing is performed on plasma with a PCR modification to improve sensitivity. The lower limit of detection of mutated NPM1 in this assay is 5 x 10-3 (0.5%). Positive results are reported quantitatively if the percentage of mutated DNA is >1%, and they are reported qualitatively if <1%.
