Polygenic Score Catalog

Definition
AI-generated

The Polygenic Score (PGS) Catalog is an open database of published polygenic scores and their performance metrics, harmonized metadata, and links to associated traits and publications.

Why it matters in GWAS

Researchers and clinicians can discover existing scores, ancestry contexts in which they were evaluated, and reporting standards—supporting equitable benchmarking as the field moves toward diverse validation.

Example usage

"Cross-cohort analyses modeled Polygenic Score Catalog to improve transferability and reduce population-structure confounding."
