Myeloproliferative neoplasms (MPNS) can many times run in families but researchers don't yet know why. The central goal of our MPN Family Study is to identify risk factors that may predispose some people to develop an MPN. This study will allow us to understand the genetic factors underlying familial MPNs and provide a potential solution to reduce the risk of MPN in family members.
We are seeking participants who have family members with two of more MPN patients. We would like to have the participation of both the MPN patients and at least one unaffected family members to volunteer in this study.
This study consists of:
· A small blood donation (50ml)
· A survey of your family clinical history
