Review outlines the methodology and clinical utility of polygenic scores in diverse populations, highlighting their potential and current limitations in precision medicine.

Key Points

To review the foundational principles, calculation methods, clinical applications, and major limitations of polygenic scores in disease risk estimation.
Reviewed statistical frameworks that combine genome-wide association study data with deeply phenotyped population biobanks to calculate polygenic scores.
Assessed methodologies for integrating individual genetic risk estimates with conventional clinical risk factors for preventive disease management.
Polygenic scores aggregate the cumulative effects of multiple common genetic variants to stratify multifactorial disease susceptibility in individuals.
Major translational hurdles include limited cross-ancestry generalizability due to European-centric datasets and the challenge of missing heritability.
Emerging methodological frameworks aim to refine score accuracy to facilitate the clinical implementation of personalized disease prevention.
