Familial Polycythemia

PFCP


Presentation

  • Eg; In cardiac complications, patient will present with chest pain, difficulty in bresthing, dizziness, sweating and other features of myocardial infarction/ angina[4].[explainmedicine.com]
  • A seven basepair direct repeat sequence is present in the normal EpoR gene at the site of this mutation, consistent with the slipped mispairing model for the generation of short deletions during DNA replication.[ncbi.nlm.nih.gov]
  • Only in one family was more than one sibling affected with any malignancy; in family 2 a brother presented with renal cancer at age 58 years and a sister with breast cancer at age 55 years. In family 4, mother presented with PV and father with CML.[nature.com]
  • Clinical description The hematological disorder is present at birth but the clinical symptoms, if they develop, can be discovered at any time during childhood or adulthood.[orpha.net]
Plethora
  • Clinical manifestations (present in some, but not all) were usually relatively mild (predominantly chronic headache and plethora) and relieved by phlebotomy (see Management ).[ncbi.nlm.nih.gov]

Workup

  • However, it has never been shown that an exhaustive workup for malignancy is cost-effective or beneficial.[drsami.com]
  • Confirming a high hemoglobin and hematcrit level is imperative before embarking on a major workup for polycythemia since a high value may return to normal without any intervention.[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]
