Summary
This paper describes the NHGRI-EBI GWAS Catalog, a major international knowledgebase that standardises and curates genome-wide association study data from published research and author submissions. The authors report significant infrastructure updates to handle growing data volume, expansion to include sequencing-based and gene-based analyses, and enhanced interoperability with complementary resources such as the Polygenic Score Catalog. The Catalog serves as a critical reference infrastructure for genetic association research, though the authors acknowledge ongoing challenges in achieving population diversity across represented traits.
Regional applicability
This infrastructure resource is internationally accessible and used by researchers, healthcare practitioners and industry worldwide, including the United Kingdom. The Catalog's emphasis on data standardisation and FAIR principles supports UK-based genomic research and precision medicine initiatives, though the authors note that increasing representation of non-European ancestry populations remains a priority for global applicability.
Key measures
Number of GWAS studies catalogued (>45,000), number of traits covered (>5000), full P-value summary statistics datasets (>40,000), annual user base (>200,000), data curation standards, interoperability metrics
Outcomes reported
The abstract describes updates to the NHGRI-EBI GWAS Catalog infrastructure, which curates and provides structured genome-wide association study data across >5000 human traits. The paper reports on expanded data types, improved interoperability with related resources, and enhanced community contribution mechanisms.
