The NHGRI-EBI GWAS Catalog: standards for reusability, sustainability and diversity

Maria Cerezo et al. Nucleic Acids Res. .

Abstract

The NHGRI-EBI GWAS Catalog serves as a vital resource for the genetic research community, providing access to the most comprehensive database of human GWAS results. Currently, it contains close to 7 000 publications for >15 000 traits, from which more than 625 000 lead associations have been curated. Additionally, 85 000 full genome-wide summary statistics datasets-containing association data for all variants in the analysis-are available for downstream analyses such as meta-analysis, fine-mapping, Mendelian randomisation or development of polygenic risk scores. As a centralised repository for GWAS results, the GWAS Catalog sets and implements standards for data submission and harmonisation, and encourages the use of consistent descriptors for traits, samples and methodologies. We share processes and vocabulary with the PGS Catalog, improving interoperability for a growing user group. Here, we describe the latest changes in data content, improvements in our user interface, and the implementation of the GWAS-SSF standard format for summary statistics. We address the challenges of handling the rapid increase in large-scale molecular quantitative trait GWAS and the need for sensitivity in the use of population and cohort descriptors while maintaining data interoperability and reusability.

Graphical Abstract

Figure 1.
(A) Number of studies added to the GWAS Catalog per year between 2019 and 2024 (until end of August), showing the growing proportion of molecular quantitative trait studies, defined as all studies annotated with the ontology terms ‘protein measurement’ (EFO_0004747), ‘metabolite measurement’ (EFO_0004725), ‘lipid measurement’ (EFO_0004529) or their child terms. (B) Of all studies annotated with these terms, 54% were annotated with a protein term, 32% with a metabolite term and 11% with a lipid term, while 3% included two or more categories.

(A) New layout of GWAS Catalog UI trait page for ‘lung cancer’. Data is loaded into each tab (e.g. Full summary statistics) only when users click, to improve performance and load times [1]. Improved pagination allows rows to be loaded in batches, with the user able to choose how many rows to display [2]. If required, pages with many rows can be downloaded for analysis offline without having to load the full dataset in the browser. (B) New page displaying all studies in the Catalog, with checkboxes to filter the table to show only specific study types (currently GxE or seqGWAS studies). (C) The Study Information panel on each Study page now includes a flag to indicate if it is a GxE study.
