Please note that due to planned maintenance, Ensembl Tools will be unavailable from Tuesday, September 9 2025, at 08:30 AM BST until Wednesday, September 10 2025, at 08:30 AM BST. 

Jobs submitted during the maintenance window will be queued and processed once maintenance is complete.

We apologise for the inconvenience. Services will be resumed as soon as the work has been completed. If you have any questions about the planned maintenance work, please contact us via the Ensembl Helpdesk.

We are experiencing issues with the Ensembl search system due to unforeseen errors. The search function is currently unavailable and this may affect other functions such as the loading of variants on genomic sequences. To search for entries in Ensembl, you can do one of the following:

  1. Use the EMBL-EBI website: go to https://www.ebi.ac.uk/ebisearch and enter your search terms into the text box. E.g. if you want to search for human BRCA2 in Ensembl, enter Ensembl human BRCA2 into the search text box.
  2. Use Google: to search for entries in Ensembl via Google, go to www.google.com and enter site:https://www.ensembl.org [search terms]. E.g. if you want to search for human BRCA2, enter site:https://www.ensembl.org human BRCA2 into Google.

We are working to fix this issue as quickly as possible, although a timeline is still unclear for the work to be completed. Services will be resumed as soon as the issue has been resolved. If you have any questions, please contact us on the Ensembl Helpdesk.
