Polycythemia Vera

 

(also erythremia, Vaquez’ disease), a chronic disease of the hematopoietic system first described by the French physician L. H. Vaquez in 1892. Polycythemia vera is characterized by an increase in erythrocyte, leukocyte, and platelet mass and in plasma volume. It is classified as a form of leukemia. The course of the disease is comparatively benign. The principal symptoms are a dark red coloration of the skin, elevated blood pressure, proneness to hemorrhaging and thrombosis, and enlargement of the spleen.

Cytological analysis of bone marrow is an important aid in diagnosis. Treatment includes phlebotomy and the administration of cytostatics.

As model genes, the researchers used JAK2, a gene that when mutated causes a bone marrow disorder known as polycythemia vera; SERP1NA1, a gene that when mutated causes alpha 1-antitrypsin deficiency, an inherited disorder that may cause lung and liver disease; and AAVS1, a gene that's been recently discovered to be a "safe harbor" in the human genome for inserting foreign genes.
A JAK2 mutation also shows up in people with polycythemia vera, a disease marked by a high red blood cell count.
