Detects MPL mutations, which are found in a subset of myeloproliferative neoplasms (MPN). DNA sequence of exon 10 including W515L/K and S505 is determined using next-generation sequencing (NGS) technology.
disease state indication(s)
Myeloproliferative neoplasms (MPN), essential thrombocythemia (ET), primary myelofibrosis (PMF)
MPL mutations are found in approximately 5% of patients with primary myelofibrosis (PMF) or essential thrombocythemia (ET). Detection of MPL mutation is included as one of the major diagnostic criteria for PMF and ET in the WHO classification of hematopoietic neoplasms.
