The Causal Effects of Blood Iron and Copper on Lipid Metabolism Diseases: Evidence from Phenome-Wide Mendelian Randomization Study. 1 The abnormal myeloproliferation of PV is sustained by a constitutively active JAK-STAT signal transduction pathway, caused by the unique V617F mutation within exon 14 (∼ 95% of PV) 2-5 and by different mutations within exon 12 (∼ 4% of PV) of the JAK2 gene. In this review, we comprehensively discuss the clinical consequences of iron deficiency in PV, provide a framework for understanding the potential dysregulation of iron metabolism, and present a rationale for additional therapeutic options for iron-deficient PV patients.

Polycythemia vera (PV) is a chronic myeloproliferative neoplasm. Although patients with iron deficiency from other causes become anemic, patients with polycythemia vera have increased RBC production and thus even when iron-deficient initially have a normal hematocrit level but an elevated red cell count and microcytic RBC indices; this combination of findings is a hallmark of polycythemia vera. Abstract The relation between whole blood viscosity and iron status was studied in 11 patients with polycythemia vera (PV) who were treated with venesection without iron supplementation.
