Functional Genomic Variation in the Epilepsies (EuroEPINOMICS)

Epigenetic pathomechanisms promoting epileptogenesis in focal and generalized epilepsies (EpiGENet)

About 1% of the population has epilepsy, and 30% of the patients lack response to currently available antiepileptic drugs. Onset and progression of drug‐resistant seizures remain, however, difficult to predict in affected patients, irrespective of their epileptogenic condition. The objective of this CRP is to characterize common epigenetic pathomechanisms of epileptogenesis. Epigenetic mechanisms are self‐perpetuating, posttranslational modifications of nuclear proteins, and DNA that can produce lasting alterations in chromatin structure and gene expression patterns. Results will be obtained from animal models and human brain specimens using advanced experimental tools, and will help to identify novel targets for pharmacotherapy in these difficult-to-treat patients.
