Summary
This 2024 Nature Genetics paper, authored by Lambert and colleagues, describes enhancements to the Polygenic Score Catalog, a curated resource for genomic prediction tools. The work focuses on developing improved computational methods for score calculation and methods to normalise scores across ancestry groups, addressing known disparities in polygenic prediction accuracy across populations. As suggested by the journal and authorship, this represents a technical advancement in making genomic prediction tools more equitable and broadly applicable in human genetic research.
Regional applicability
The tools and methods described would be applicable to UK biobanks and clinical genomics programmes (such as those in the NHS Genomic Medicine Service) seeking to implement polygenic scoring whilst accounting for ancestry diversity in the UK population. Improved ancestry normalisation is particularly relevant given the growing ethnic diversity of UK genetic cohorts.
Key measures
Polygenic score calculation accuracy, ancestry-normalisation algorithms, catalog completeness and usability metrics
Outcomes reported
The study presents enhanced tools and methods for calculating polygenic risk scores and normalising them across diverse ancestry groups. The work addresses technical and computational approaches to improve the accessibility and applicability of polygenic scores in genomic research.
