Increased PRV-1 mRNA expression and the presence of Jak2(V617F) mutation in peripheral blood granulocytes are specific markers for chronic myeloproliferative disorders (MPD), which facilitate the differential diagnosis between polycythemia vera (PV) and secondary erythrocytosis (SE) and may be helpful for monitoring treatment efficacy in MPD patients.
