Mutations of JAK2V617F, JAK2 exon 12, MPL W515L/K and CALR were analysed in 439 Argentinean patients with BCR-ABL1-negative MPN, including 176 polycythemia vera (PV), 214 essential thrombocythemia (ET) and 49 primary myelofibrosis (PMF).
Moreover, the combination of BMN673, ruxolitinib, and hydroxyurea was highly effective in vivo against JAK2(V617F)<sup>+</sup> murine MPN-like disease and also against JAK2(V617F)<sup>+</sup>, CALR(del52)<sup>+</sup>, and MPL(W515L)<sup>+</sup> primary MPN xenografts.
Concurrence of B-lymphoblastic leukemia and myeloproliferative neoplasm with copy neutral loss of heterozygosity at chromosome 1p harboring a MPL W515S mutation.
A multiplex snapback primer system was developed for the simultaneous detection of JAK2 V617F and MPL W515L/K mutations in Philadelphia chromosome- (Ph-) negative myeloproliferative neoplasms (MPNs).
Constitutively active JAK2V617F and thrombopoietin receptor (TpoR) W515L/K mutants are major determinants of human myeloproliferative neoplasms (MPNs).
Acquired mutations in the juxtamembrane region of MPL (W515K or W515L), the receptor for thrombopoietin, have been described in patients with primary myelofibrosis or essential thrombocythemia, which are chronic myeloproliferative disorders.
To investigate its prevalence in Chinese patients with MPD, we introduced allele-specific PCR (AS-PCR) combined with sequence analysis to simultaneously screen MPL W515L and JAK2 V617F mutations in 190 MPD patients.
