Gene Set Enrichment Analysis (GSEA) is a computational method that determines whether an a priori defined set of genes shows statistically
significant, concordant differences between two biological states
(e.g. phenotypes).

What's New

24-Mar-2023: With the release of MSigDB 2023.1 we are introducing a SQLite database for the gene sets in both the Human (2023.1.Hs) and the Mouse (2023.1.Mm) resources. This new format brings the MSigDB contents and metadata with all of the searchability and manipulative power of a full relational database. See our documentation for more details on the contents and usage.

3-Mar-2023: MSigDB 2023.1 released. Updated to gene data from Ensembl 109. Human and Mouse collections for Reactome, GO, and WikiPathways have been updated, as well as HPO, Lung atlas sets from He et al. have been added to C8, and Uterine cell types from Zhang et al to M8, plus new user-submitted sets for C2 and M2 CGP. See the release notes for details.

2-Oct-2022: GSEA 4.3.2 released. This is a minor release to fix a bug on the species consistency check. See the release notes for details.

7-Sep-2022: Announcing the first release of Mouse MSigDB (v2022.1.Mm) with ~16,000 gene sets that can be used directly for GSEA analysis of mouse datasets without the need for orthology conversion. A new release of Human MSigDB (v2022.1.Hs) includes updates to Reactome, GO, HPO, and WikiPathways. See the 2022.1.Hs release notes and 2022.1.Mm release notes for details.

7-Sep-2022: GSEA 4.3.0 released. Adds support for convenient access to the new Mouse MSigDB database and makes adjustments for our new versioning scheme. See the release notes for details.

29-Mar-2022: MSigDB gene sets are now available as JSON bundles. Check our Downloads page for the full collections. Smaller bundles as well as extended metadata in TSV format are available from our Search page.

1-Mar-2022: GSEA 4.2.3 released. There is a new correlation metric (Spearman) and a new collapse mode (Absolute Max), plus better handling of missing values and many other fixes in 4.2.x. Log4J has been removed entirely from the code to avoid vulnerability concerns. All users are encouraged to update! See the release notes for details.

A big thank you to everyone who responded to our request for emails of support for our grant application resubmission.
Reading them made us feel so appreciated and valued by all of you.

We hope we can continue to bring you GSEA/MSigDB in the years to come.
