Hereditary Parkinson Disease Natural History Protocol
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Background: \- Parkinson s disease is a disease of the nervous system that affects movement. People usually get it in their 70s or 80s. Early onset Parkinson s disease (EOPD) begins before the age of 50. Researchers think EOPD may be caused by a mutation in a gene. They want to study the genetic causes so they can find therapies for this disease. Objective: \- To better understand the genetic causes of EOPD. Eligibility: * Adults ages 18 80 with a history of EOPD. Their family members, who do not have Parkinson s disease, can join as controls. * Healthy volunteers ages 18 80. Design: * Participants with EOPD and their relatives will be screened with a review of medical records. Healthy volunteers will have medical history, physical exam, and blood drawn. * Relatives may send blood samples to NIH to test for mutations in genes that are linked to Parkinson s disease. They may have a physical exam. * Participants may be asked to return to clinic for another visit that can last up to 2 hours. * During this visit, participants will have blood taken from a vein in the arm via a needle stick. * Participants may give a sample of their skin. The skin on the arm or leg will be numbed and a small skin punch biopsy will be taken with a special needle. * Some cells from the blood or skin sample may be grown in a lab to establish cell lines. The cells may also potentially be genetically modified to make stem cells. * Researchers may perform genetic analysis on the samples to compare them to EOPD patient samples.
