Some cases of primary erythrocytosis are due to a mutation of the receptor for the main erythroid-stimulating cytokine, erythropoietin (Epo). The mutations are germianal, i.e. not restricted to hematopoietic cells. They are most often inherited (family history of erythrocytosis) but they can also happen de novo.
