AIMS: The molecular pathogenesis of essential thrombocythaemia (ET) is heterogeneous. We aimed to determine the relative sensitivity of four separate molecular assays used to detect the presence of the JAK2 V617F mutation in peripheral blood from patients with essential thrombocythaemia and related myeloproliferative disorders. METHODS: Purified granulocytes from 60 patients were analysed for the presence of the JAK2 V617F mutation by direct sequencing, denaturing high-performance liquid chromatography (DHPLC), allele-specific polymerase chain reaction (PCR) and allele-specific enrichment. Clinical data were collected for all patients and correlated with assay results. RESULTS: Direct sequen..
