Outcome Measures

Primary Outcomes (1)

  • Assay Evaluation

    Evaluate each assay performance for ability to detect LRRK2, its activity and/or the detection and activity of the pathways it impacts using a variety of different approaches (quantitative western blot, immunoassays and LC-MS).

    1 year

Study Arms (4)

Sampling MethodNon-Probability Sample
Study Population

Approximately 140 participants will be enrolled to participate in this study, with a goal of enrolling 30 non-manifesting LRRK2 carriers, 30 LRRK2 Parkinson's Disease (PD), 40 idiopathic PD, and 40 healthy controls.

You may qualify if:

  • Ability to provide informed consent
  • Confirmed LRRK2 G2019S mutation
  • Age 30 years or older at date of informed consent.

You may not qualify if:

  • Inability to provide informed consent
  • Known GBA mutation carrier
  • Participation in a blinded clinical trial of any kind or an unblinded trial of an investigational product that is not currently approved for use in humans. Participants that have had a 6 - month washout period between ending participation in a clinical trial with an investigational agent and enrollment into the ECV-004 study are eligible.
  • The presence of rest tremor, bradykinesia or rigidity.
  • The presence of any other neurological sign that in the opinion of the site investigator raises suspicion for an atypical parkinsonian syndrome (e.g. supranuclear gaze palsy)
  • Treatment for cancer in the last 5 years or cancer patient receiving immunotherapy or targeted therapy. Individuals with cancers that have not been treated with systemic chemotherapy, immunotherapy, targeted therapies or radiation therapy are eligible to enroll in the study.
  • Diagnosis of an autoimmune disorder
  • Current treatment with anticoagulants that might preclude safe completion of the lumbar puncture and that cannot be safely paused in the opinion of the site investigator.
  • Any condition that, in the investigator's opinion, precludes the safe performance of routine lumbar puncture, such as prohibitive lumbar spinal disease, bleeding diathesis, or clinically significant coagulopathy or thrombocytopenia.
  • Diagnosis of dementia
  • Pregnant females, if fluoroscopy is needed to obtain the spinal fluid sample
  • LRRK2 Parkinson Disease (PD) Participants:
  • Ability to provide informed consent
  • Confirmed LRRK2 G2019S mutation
  • Meet the MDS criteria for Parkinson's disease
  • +35 more criteria
