The DNA and Cell Bank of Instituts Federatifs de Recherche (IFR) of Neurosciences has been running for the last 15 years at the Institut National de la Santé Et de la Recherche Médicale (INSERM) Unit 679 (former unit 289). Since its creation, this structure has been the support of research projects in genetics for neurological and psychiatric disorders. The cohorts established have led to discoveries in monogenic disorders, such as cerebellar ataxias, spastic paraplegias, frontotemporal dementias, epilepsies, Parkinson’s and Alzheimer’s disease, Charcot-Marie-Tooth disease and related entities. The research projects based on the study of the genetic bases in Parkinson’s disease and epilepsies are especially developed for this grant.
