Heat at the synapse – STX1B mutations in fever-associated epilepsies

Febrile Seizures. The discovery of the genes for fever-associated epilepsies was one of the most relevant milestones in epilepsy genetics. Discovery of the underlying genes including SCN1A, SCN1B and GABRG2 was tightly linked to the development of the Genetic/Generalized Epilepsy with Febrile Seizures Plus (GEFS+) concept, describing the spectrum of epilepsy phenotypes seen in families with these mutations. Gene discovery in GEFS+, however, has slowed down in recent years, and no further causative genes had been identified for more than a decade. Now, in a recent paper in Nature Genetics, mutations in STX1B are found as a novel cause for fever-associated epilepsies. Continue reading

The top three publications in epilepsy genetics 25 years ago

Looking back. In this week’s ILAE Genetics Commission post, we would like to look 25 years back and examine the most important publication in the field in 1989, the year the Berlin wall fell. What concepts did we have back then and how did our understanding of epilepsy and genes change? Here are the top three publications of 1989. Continue reading
