摘要

Familial polycythaemia (erythrocytosis) is comprised of several inherited disorders arising from diverse aetiological factors. Primary polycythaemias are characterized by defects within erythroid progenitors, which either grow independently/ or are hypersensitive to erythropoietin (EPO), while secondary polycythaemias are from circulating factors, such as EPO. Secondary familial polycythaemias are due to increased haemoglobin oxygen affinity (a, (3, and у globins and bisphospho-glycerate mutase mutations), while the primary familial polycythaemias are due to gain-of-function of EPO receptor (Gordeuk et al, 2005) and T-cell acute leukaemia 1 (TALI) (Rogers et al, 2012) mutations.. Mutations of the hypoxia-inducible factor (HIF) pathway present as either secondary (Lorenzo et al, 2013) or with features of both primary and secondary polycythaemias (Chuvash polycythaemia) (Gordeuk et al, 2005).
