National Parkinson's biobank with whole genome sequencing and patient-derived stem-cell testing
Official title: Implementing a National Biobank of Genetic, Sporadic and Prodromic Parkinson's Disease With Whole Genome Analysis and Functional Assessment of Polygenic Inheritance by iPSC Technology
Run by IRCCS San Raffaele · NCT05721911 · Data updated 2026-11-12
This project will test whether combining whole genome sequencing and patient-derived stem cells can help find rare genetic changes linked to Parkinson's disease and REM sleep behavior disorder.

Is this trial a fit for you?
✓Likely a good fit
Ideal participants are adults with sporadic Parkinson's disease who meet clinical diagnostic criteria (at least two cardinal signs, including tremor or bradykinesia), people with idiopathic REM sleep behavior disorder per ICSD-3, and healthy controls (often spouses).
✕Probably not a fit
People with atypical parkinsonism, known monogenic Parkinson's mutations, major psychiatric disorders, or other neurodegenerative diseases are unlikely to gain direct benefit from this observational genetic and iPSC-focused project.

What this trial studies
This multicenter observational project will create a standardized national biobank of blood, DNA, and cellular samples from people with Parkinson's disease (PD), REM sleep behavior disorder (RBD), and healthy controls. Teams will harmonize clinical reporting and sample collection across centers, recruit additional participants, and perform whole genome sequencing on a selected cohort (about 200 PD cases negative for known PD gene mutations) as well as on RBD patients. Investigators will generate and quality-control induced pluripotent stem cell (iPSC) lines from patient blood and use gene editing to test the functional effects of co-inherited rare coding variants as a potential polygenic driver of sporadic PD. The biobank and validated iPSC lines will be made available to the scientific community to support further research.
Why it matters
Potential benefit: If successful, this could lead to earlier genetic diagnosis, better understanding of disease mechanisms, and identification of new targets for treatments.
How similar studies have gone: Whole genome sequencing and iPSC modeling have previously linked some rare variants to Parkinson's biology, but using gene-edited iPSCs to functionally test the combined impact of multiple rare variants as a polygenic mechanism is relatively novel.
