Brief Summary:

Parkinson's disease (PD) is one of the most common neurodegenerative disorders worldwide, affecting approximately 1% of individuals older than 60 years and causes progressive disability.

PD is mostly considered as idiopathic disease, however more and more data suggest that it is a disease that involves interaction of genetic and environmental factors. The most common monogenic form and the one most closely resembling idiopathic PD is LRRK2 (Leucine-rich repeat kinase 2 gene) associated PD.

The aims of this study are the identification of 1,500 LRRK2-positive patients, the identification of 1,500 non-LRRK2 PD patients (including a subset of ~500 patients with monogenic PD patients other than LRRK2) and the establishment of a candidate biomarker in the LRRK2-positive cohort.

Groups and Cohorts
Go to 
Top of Page Study Description Study Design Groups and Cohorts Outcome Measures Eligibility Criteria Contacts and Locations More Information

Group/Cohort Intervention/treatment
Parkinson disease individuals Genetic: Blood Test
LRRK2 hotspot mutations and the whole GBA gene will be sequenced. If LRRK2 hotspots and GBA sequencing are both negative and the subject has an early PD onset and/or a PD family history and is willing to participate in further genetic screening, 68 PD associated genes will be sequenced. In case of the negative result and if the participant has an early disease onset and/or a PD family history and is willing to participate in extended genetic screening, Whole Genome Sequencing (WGS) will be performed.
Family member of a participant with LRRK2 parkinsonism Genetic: Blood Test
LRRK2 hotspot mutations and the whole GBA gene will be sequenced. If LRRK2 hotspots and GBA sequencing are both negative and the subject has an early PD onset and/or a PD family history and is willing to participate in further genetic screening, 68 PD associated genes will be sequenced. In case of the negative result and if the participant has an early disease onset and/or a PD family history and is willing to participate in extended genetic screening, Whole Genome Sequencing (WGS) will be performed.
High risk population with an early PD onset Genetic: Blood Test
LRRK2 hotspot mutations and the whole GBA gene will be sequenced. If LRRK2 hotspots and GBA sequencing are both negative and the subject has an early PD onset and/or a PD family history and is willing to participate in further genetic screening, 68 PD associated genes will be sequenced. In case of the negative result and if the participant has an early disease onset and/or a PD family history and is willing to participate in extended genetic screening, Whole Genome Sequencing (WGS) will be performed.


Outcome Measures
Go to 
Top of Page Study Description Study Design Groups and Cohorts Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Epidemiological analysis of the prevalence of LRRK2-positive patients in a cohort of PD patients [ Time Frame: 1 day ]
    Number of participants with a mutation/pathogenic variant in their LRRK2 gene within a cohort of 10,000 participants with Parkinson's Disease or are at high risk for Parkinson's Disease, tested using a dry blood sample and next generation sequencing with confirmation by Sanger sequencing


Secondary Outcome Measures :
  1. Epidemiological analysis of the prevalence of patients with PD-related gene alterations (other than LRRK2 gene) in a cohort of PD patients [ Time Frame: 1 day ]
    Number of patients showing with a mutation/pathogenic variant in their PD-related genes (other than LRRK2 gene) within a cohort of 10,000 with Parkinson's Disease or are at high risk for Parkinson's Disease, tested using a dry blood sample and next generation sequencing with confirmation by Sanger sequencing


Other Outcome Measures:
  1. Establishment of candidate LRRK2-positive biomarkers in the LRRK2-positive cohort [ Time Frame: 1 day ]
    The quantitative determination of small molecules (molecular weight 150-700 kD, given as ng/μl) within a dried blood spot sample in LRRK2-mutation positive Parkinson's participants will be validated via liquid chromatography multiple reaction-monitoring mass spectrometry and compared with LRRK2-mutation negative Parkinson's participants as well as LRRK2 mutation carriers (without Parkinson's disease)


Biospecimen Retention:   Samples With DNA

The participants fulfilling the eligibility criteria will be enrolled into the Study and genetically tested for LRRK2 hotspot mutations and the whole GBA gene will be sequenced. If LRRK2 hotspots and GBA sequencing are both negative and the subject has an early PD onset and/or a PD family history and is willing to participate in further genetic screening, 68 PD associated genes will be sequenced. In case of the negative result and if the participant has an early disease onset and/or a PD family history and is willing to participate in extended genetic screening, Whole Genome Sequencing (WGS) will be performed.

LRRK2-positive samples will be validated for the identification of potential biomarkers (based on MS/MS-Spectroscopy) and compared with a merged control sample in order to establish a LRRK2 specific biomarker.
