Open Targets Genetics: version 7 is out!

Release Notes Feb 25, 2022

The latest release of the Open Targets Genetics portal – version 7 – is now available at

This release integrates some new data and features both behind-the-scenes and user interface improvements.

Key points

New data

This release includes:

Data fixes

Colocalisation data

As described on the Open Targets Community, one of our users identified an issue with the colocalisation data. 10-30% of QTL colocalisations (both GWAS-GWAS and GWAS-QTL colocs) reported low values when they should have been high. Colocalisation data from our previous release should not be used.

This mainly affected regions where a GWAS or QTL study has multiple signals within 1 Mb of each other. The error was due to a failure to use the conditionally-independent summary statistics for each “independent” signal; the marginal summary statistics were used even when we were considering colocalisations with a secondary signal at a locus.

We solved this issue by re-running the >4 million colocalisation tests. This was also an opportunity to optimise our pipeline, which is now considerably more efficient: we are now able to run the tests in a day, rather than a week.


Betas are the effect size estimates for SNPs. A small number of studies, mainly older ones, had flipped betas in GWAS catalog i.e. betas that should have been positive were negative, and vice versa. Although these were corrected in GWAS Catalog, we hadn't updated our internal data.

The studies it affected are: GCST004131; GCST004132; GCST004133; GCST001725; GCST001728; GCST001729; GCST000964; GCST000758; GCST000760; GCST000755; GCST000759.

Improvements to the front-end

The Genetics portal features new headers on the variant, gene, and study pages. The information showcased is now much easier to digest with clearly visible cross-reference links.

The new header on the PCSK9 gene page
The new header on the rs4129267 variant page
The new header on the LDL cholesterol (Willer CJ et al. 2013) study page

In the background, we're also working to improve the infrastructure of the portal for a more fluid user experience.
