Epi25 – redefining epilepsy genetics through exomes of 17,000 individuals

The Epi25 study. On August 1, the Epi25 study was published in the American Journal of Human Genetics. Epi25 is the major, international effort to understand the genetics of common and rare epilepsies through exome sequencing, and our current study now presents the first results on what we can see if we look at the genetics of the epilepsies in thousands of individuals, including more than 9,000 persons with epilepsy and 8,000 controls. The Epi25 study finds that individuals with epilepsy carry more ultra-rare, deleterious variants than controls, especially in known or presumed candidate genes. This is a significant finding that tells us about the inner genetic architecture of the epilepsies beyond the role of monogenic causes. However, as with many previous studies at this scale, the first publication merely scratches the surface and provides an enormous amount of data for further studies. Here is a brief summary of the Epi25 study and some of the most prominent genes in the epilepsies that were completely unknown previously. Continue reading

Navigating the epilepsiome – live from Tübingen

2D. I am writing this post during our EuroEPINOMICS meeting in Tübingen listening to presentation from CoGIE, the EuroEPINOMICS project working on IGE/GGE and Rolandic Epilepsies and RES, the project on rare epilepsies. At some point during the afternoon, I made my selection for the best graph during the presentations today – an overview of the conservation space of epilepsy genes. Continue reading

Invitation for the EuroEPINOMICS General Assembly in Tübingen

We need to talk. Much has happened in EuroEPINOMICS land ever since the launch of this Eurocores activity in 2011. Back then, exomes were still a realistic, but somewhat remote possibility and the complexity and ambiguity of the human genome was only beginning to be revealed. Now, roughly two years later, we have witnessed major breakthroughs in understanding epilepsy through genetic findings and we have generated large datasets on common and rare epilepsy syndromes that require an unanticipated effort for data mining and sharing. The EuroEPINOMICS Consortium will hold its 2013 General Assembly in Tübingen, Germany, from 30.10-01.11.2013. This meeting will connect all four Collaborative Research Projects and will be the central meeting of this year to jointly discuss our current activities and plans for the future. Continue reading
