Test Code Billings Clinic 9346 Nucleophosmin (NPM1) Mutation Analysis
Performing Laboratory
NeoGenomics
Useful For
NPM1 encodes for a nuclear protein involved in the regulation of tumor suppressor activity. NPM1 mutations cause abnormal cytoplasmic localization of the protein, interfering with ribosomal assemply and other key pathways. Among myeloid neoplasms, NPM1 mutations are found in MDS, AML, and CMML.
Methodology
Next-Gen Sequencing (NGS)
