GGE. The Genetic Generalized Epilepsies (GGE) are common epilepsies in children and adults with a prominent genetic contribution. However, genetic risk factors for GGE have been more difficult than most researchers would have expected to pin down. Genome-wide association studies for common variants and association studies for ultra-rare variants have been able to identify several candidate genes, but much of the genetic risk for GGE remain unaccounted for. In a recent study in Lancet Neurology, we have tried a different approach to address the genetic contribution for GGE, looking at gene groups rather than single genes. Using this approach, we were able to detect a signal that would not have been found when looking at individual genes alone, a contribution of rare variants in genes for GABA-A receptors that reliably spans across three different cohorts.

Publications of the week – GABRB3, SLC2A1, and SCN1A
No novel genes. This was actually a slow week with respect to publications in epilepsy genetics. No new gene was published, so we’ll focus on three publications that tell us bit more about three genes that we already know. This week’s publications cover new reports on GABRB3, SLC2A1, and SCN1A in brain malformations. Continue reading
