- Genetic: G2019S LRRK2
No cost genetic testing for G2019S LRRK2
- Identify Parkinson's patients with the G2019S mutation in their LRRK2 gene [ Time Frame: 2 years ]To identify Parkinson's patients with the G2019S mutation in their LRRK2 gene through whole exome sequencing in order to support the development of an oral precision medicine.
- Understand the proportion of Parkinson's patients who have a G2019S LRRK2 mutation [ Time Frame: 2 years ]To obtain information about the proportion of Parkinson's patients who have a G2019S LRRK2 mutation.
- Increase awareness of the importance of genetic testing in Parkinson's disease [ Time Frame: 2 years ]To increase healthcare provider and patient awareness of the importance of genetic testing in Parkinson's disease in order to be aware of potential eligibility for clinical studies of genetic targeted medicines.
- Increase interest of healthcare providers and patients participation in clinical trials [ Time Frame: 2 years ]To engage healthcare providers and patients' interest in participation in upcoming clinical studies.

Ages Eligible for Study: | 18 Years and older (Adult, Older Adult) |
Sexes Eligible for Study: | All |
Accepts Healthy Volunteers: | No |
Sampling Method: | Probability Sample |
Participants include those with a clinical diagnosis of Parkinson's, in particular those who have a first- or second-degree relative with Parkinson's, or who have young onset Parkinson's (age less than 50 at diagnosis) or are of Ashkenazi Jewish or North African Berber descent, or have a relative with a known genetic mutation in the LRRK2 gene, or who have a genetic mutation in the LRRK2 gene.
Inclusion Criteria:
Participant eligible for enrollment in the program must meet all of the following criteria:
- Participant must be a person diagnosed with Parkinson's disease who is 18 years or older.
- Participant is under the care of a physician for their Parkinson's disease.
- Participant is able to read, write and understand English, and reside in a country where the shipment of biological samples is allowed.
- Participant is able to grant informed consent.
- In the case of participants, willing to participate in a free genetic testing program to determine if they carry the G2019S LRRK2 mutation.
- Willing to be notified of eligibility for clinical studies (if appropriate).
- Particpants who already believe they have tested positive for the mutation will be allowed to be retested through this program and be notified of potential eligibility for studies.
Exclusion Criteria:
- Inability to meet any of the inclusion criteria.
- Participant has received on of the following advanced treatments to manage their Parkinson's: gene therapy, deep brain stimulation (DBS), injections into the brain, continuous infusion of medication into their stomach/intestines with a pump.
