The ROPAD study aims to genetically characterize around 10,000 Parkinson's disease patients, with initial data from 1360 participants indicating a genetic diagnostic yield of approximately 14%. This demonstrates the feasibility and effectiveness of the screening protocol for high-throughput genetic characterization and prioritization for research efforts and clinical trials.
Background Genetic stratification of Parkinson's disease (PD) patients facilitates gene-tailored research studies and clinical trials. The objective of this study was to describe the design of and the initial data from the Rostock International Parkinson's Disease (ROPAD) study, an epidemiological observational study aiming to genetically characterize similar to 10,000 participants. Methods Recruitment criteria included (1) clinical diagnosis of PD, (2) relative of participant with a reportable LRRK2 variant, or (3) North African Berber or Ashkenazi Jew. DNA analysis involved up to 3 successive steps: (1) variant (LRRK2) and gene (GBA) screening, (2) panel sequencing of 68 PD-linked genes, and (3) genome sequencing. Results Initial data based on the first 1360 participants indicated that the ROPAD enrollment strategy revealed a genetic diagnostic yield of similar to 14% among a PD cohort from tertiary referral centers. Conclusions The ROPAD screening protocol is feasible for high-throughput genetic characterization of PD participants and subsequent prioritization for gene-focused research efforts and clinical trials.
