The DMuDB service is to continue.

Following the recent announcement that this service was to close, in a new initiative between EMQN and Certus Technology, DMuDB will continue in its current form. Over the coming months plans will emerge for the future of this service. We will publish updates on this site.

Date: 3rd May 2018

The Diagnostic Mutation Database (DMuDB) is a secure repository of clinical quality variant data collected from diagnostic genetics laboratories. Access to DMuDB is available by annual laboratory subscription, and must be for diagnostic purposes only. See the Use Policy for details.

DMuDB is accessed through this secure website, the data can also be accessed through a graphical browser, which is the preferred method for viewing data and also allows access to other mutation databases.

Subscription and pricing

As of March 2014 we are no longer accepting new subscriptions for DMuDB. For further information please contact us at support@dmudb.net.

Non-diagnostic use of DMuDB data

Access to DMuDB is not permitted for any purpose other than the investigation and interpretation of patient results in order to provide a diagnosis. Researchers or healthcare professionals wishing to query the database and obtain data that may be held there should contact us (support@dmudb.net) with their request, which will be passed on to laboratories that have submitted relevant data. It may be possible for data to be shared for research and other non-diagnostic purposes but this must be done with express permission of the submitting laboratory and with data transfer agreements in place.
