NPM (Exon 12) Mutation Analysis, Cell-based
FLT3 Mutation Assay
Preferred Specimen
5 mL whole blood collected in an EDTA (lavender-top) tube
Minimum Volume
Whole blood: 3 mL • Bone marrow: 1 mL • Tissue: 2x3 mm
Other Acceptable Specimens
3 mL bone marrow collected in an EDTA (lavender-top) tube • Cell pellet collected in a sterile transport tube • 5x5 mm tissue collected in a paraffin block
Instructions
Do not reject. Send to lab for evaluation.
Whole blood (preferred): Follow standard whole blood collection procedure. Collect 3-5 mL whole blood samples in an EDTA tube. Blood samples are shipped at room temperature or 4° C. Do not freeze whole blood. Record the draw time and date on the tube. Ship immediately to maintain sample stability.
Cell pellet: This assay is also designed for the remnant cell pellet from Cytogenetics. The cell pellet usually fixed should be transported refrigerated to the laboratory as soon as possible. Please provide a copy of the Cytogenetics report.

Clinical Significance
This testing, consisting of FLT3, NPM-1, and CEBPA, is recommended in the NCCN guidelines for determination of AML risk status in patients with cytogenetically normal AML. The presence of CEBPA gene mutations is associated with increased disease-free survival and overall survival. Mutations in NPM1 gene is a predictor of favorable prognosis and good response to induction chemotherapy. The presence of (FLT3) internal tandem duplication is associated with short disease-free survival.
