Clinical Info

As a prognostic indicator in patients with newly diagnosed acute myelogenous leukemia with normal karyotype and no FLT3 variant and as a leukemia-specific marker of minimal residual disease.
Testing Algorithm
Both DNA and RNA are extracted. The assay is composed of 2 parts, an RNA-based, sensitive quantitative reverse transcription real-time polymerase chain reaction (RT-PCR) that detects and quantifies the most common altered NPM1 messenger RNA transcripts (A, B, D forms) in acute myeloid leukemia (AML), and a DNA-based qualitative NPM1 exon 12 variant screening by fragment analysis that detects essentially all altered forms reported in AML, including the rare non-A, B, D forms (with lower sensitivity at the DNA level).
