A Nature Communications study introduced PGS-hub, a benchmarking platform comparing single-ancestry and multi-ancestry polygenic scores across traits and populations. The authors (Chen, Wang, Zhao et al.) systematically evaluated predictive performance and highlighted limitations when applying scores across diverse ancestries. The resource provides standardized metrics and datasets for the genetics community. The platform aims to accelerate development of equitable polygenic tools and to identify where multi-ancestry models improve portability. Clinical genomics groups and companies building risk-prediction products will use these benchmarks to validate models prior to deployment.
