Familial Myeloproliferative Disorders

Completed

• Conditions: Polycythemia Vera; Essential Thrombocythemia; Idiopathic Myelofibrosis

• Registration Number: NCT00666289
• Lead Sponsor: Icahn School of Medicine at Mount Sinai

Brief Summary

Myeloproliferative disorders occur in families, thus giving rise to the theory that it is a genetic disease that may be caused by an abnormal gene in the DNA that can be passed from one generation of family members to another. DNA can be gathered from family members through blood samples and the investigators will investigate (through DNA testing) to see if there are abnormal genes that may be responsible for causing the MPDs. Understanding which genes are responsible for causing MPDs can help develop ways to identify people who may be at risk for developing an MPD, allow for the development of better treatments, possibly a cure, or even prevent the development of MPDs.
