He had headaches and marked plethora. Erythropoietin levels were not elevated. The disorder was characterized in middle age in other members of the family by hypertension, cardiovascular and thromboembolic phenomena, and abnormal bleeding. [datapunk.net]
Typical findings for polycythemia: In many children the only manifestation will be plethora. Alternatively, polycythemia may be discovered inadvertently on a routine CBC. Other symptoms may include headache, pruritus, dizziness and sweating. [clinicaladvisor.com]

Prognosis
Prognosis Primary familial polycythemia does not necessarily carry an adverse prognosis in early life and most patients have a benign clinical course, but it is associated with an increased risk of thrombosis and vascular mortality in later life. [orpha.net]
It is hoped that greater knowledge of prognosis may be obtained by further observations of these patients. Received May 28, 1957. Accepted July 25, 1957. [pediatrics.aappublications.org]

There are two distinct forms of the disease: Primary polycythemia (polycythemia vera) is a myeloproliferative disorder of unknown etiology. [medical-dictionary.thefreedictionary.com]
Etiology Primary familial polycythemia is caused by mutations in the EPO receptor ( EPOR ) gene (19p13.3-p13.2) resulting in hypersensitivity to EPO. [orpha.net]
