Dementias Platform UK: Bringing genetics into life.

Area of Science:

• Genetics
• Neuroscience
• Data Science

Background:

• Neurodegenerative dementias exhibit complex and poorly understood genetic heterogeneity.
• The Dementias Platform UK (DPUK) Data Portal aggregates diverse cohort data.
• Combining genetic and phenotypic data across cohorts can advance neurodegeneration research.

Purpose of the Study:

• To process and harmonize genetic data from multiple cohorts within the DPUK Data Portal.
• To make research-ready genetic data and polygenic risk scores (PRS) available to the research community.

Main Methods:

• Development of standardized pipelines for genetic data processing, including quality control and imputation.
• Application of these pipelines to five independent cohorts, utilizing six genome-wide association studies for neurodegenerative diseases.
• Derivation of polygenic risk scores (PRS) for neurodegenerative diseases.

Main Results:

• Processed and harmonized genome-wide genetic data are now available on the DPUK platform.
• Research-ready imputed genetic data and PRS scores are accessible via the DPUK application process.
• Standardized pipelines enable scalable and efficient genetic data analysis.

Conclusions:

• Harmonizing genome-wide data across multiple datasets significantly enhances research opportunities.
• The DPUK platform provides a valuable resource for large-scale genetic analysis of neurodegenerative dementias.
• Increased accessibility of processed genetic data accelerates research pace and scope.
