FoxBioNet: LRRK2-002: Detection of LRRK2 Activity in Human Biospecimens

The overall objective of this study is to determine whether LRRK2 kinase activity and/or
mitochondrial DNA (mtDNA) damage could serve as potential biomarkers in PD.

Primary Objectives:

- Assess the levels of phosphorylated LRRK2 and LRRK2-phosphorylated Rabs, as measures of
LRRK2 kinase activity, in PBMCs and neutrophils from LRRK2 PD, idiopathic PD,
non-manifesting LRRK2 mutation carriers and healthy controls.

- Assess the levels of mtDNA damage in buffy coat from LRRK2 PD, idiopathic PD,
non-manifesting LRRK2 mutation carriers and healthy controls.

- Correlate LRRK2 kinase activity to mtDNA damage in blood from LRRK2 PD, idiopathic-PD,
non-manifesting LRRK2 mutation carriers and healthy controls.

Secondary Objectives:

- To assess the ability of the network to efficiently conduct a study involving biosample
collection for PD research. Efficiency will be assessed using measures of the time taken
to meet specific milestones within the study.

- To assess the ability of the network to collect high quality biospecimens adhering to
agreed-upon, standardized protocols

- To gauge the willingness of participants to participate in subsequent Fox BioNet studies
