    Polygenic risk scores (PRSs) are limited in clinical translation due to their development primarily in European-ancestry datasets.

  • 2

    PRS performance varies significantly across populations, with marked inaccuracies observed in Hispanic, South Asian, East Asian, and African groups.

  • 3

    Admixed populations present unique challenges for PRS accuracy, as local ancestry and genetic diversity influence predictive performance.

  • 4

    Recent advancements in PRS methodologies include multi-ancestry frameworks and local-ancestry-aware models, improving predictive performance.

  • 5

    The future of precision cardiovascular medicine relies on developing clinically useful PRS-informed risk assessments for diverse populations.
