Fox BioNet Project: LRRK2-002

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
