Abstract excerpt
Erythrocytosis can arise from deregulation of the erythropoietin (Epo) axis resulting from defects in the oxygen-sensing pathway. Epo synthesis is controlled by the hypoxia inducible factor (HIF) complex, composed of an alpha and a beta subunit. There are 2 main alpha subunits, HIF-1 alpha and HIF-2 alpha. Recently, a HIF-2 alpha Gly537Trp mutation was identified in a family with erythrocytosis. This raises the...
