Parkinson’s Progression Markers Initiative (PPMI) Data Repository

The PPMI Data Repository contains de-identified clinical, imaging, and 'omics data collected through the PPMI study — an ongoing longitudinal study, launched in 2010, with the mission of identifying biomarkers of Parkinson’s disease progression.

PPMI Data Repository Datasets

  • PPMI

    The Parkinson’s Progression Markers Initiative (PPMI) is an ongoing longitudinal observational study with more than 1,500 participants contributing comprehensive clinical and imaging data and biological samples.

  • PPMI RNA Sequencing Project

    The PPMI RNA Sequencing Project includes transcriptomics data generated from raw sequencing reads of 1,600 PPMI whole blood samples.

PPMI Data Repository Resources

  • Data Collection Standards: Review the strict protocols and schedules for data and specimen collection in the PPMI study, including the documents and operations procedures supplied to clinical sites. 
  • Available Biospecimens: Qualified researchers can also requests biospecimens collected through the PPMI study for biomarker verification studies.
Coming Soon!

    The Foundational Data Initiative for Parkinson's Disease (FOUNDIN-PD) study includes transcriptomics data generated from induced pluripotent stem cell (iPSC) lines derived from PPMI whole blood samples.
