Cohorts and Collections: Clinical and Genetic Study of Parkinson's Disease and Epilepsies

Study Overview
=================
Brief Summary
-----------------
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. Concerning Parkinson's disease, the project is based on the extension of the existing cohort throughout the French Parkinson's Disease Study Group network. Concerning epilepsies, this project is the occasion to build this network with the constitution of a new cohort. The specific aims of the scientific projects are the following for Parkinson's disease: to evaluate the frequency, the nature and the phenotype associated with parkin mutations in familial or sporadic forms of the disease, according to the age at onset, and to identify the genetic susceptibility factors in Parkinson's disease with the study of affected sibpairs and with case/controls association studies. For epilepsies, the aims are: to evaluate the frequency, the nature and the phenotype associated with SCN1A, SCNab and GABR2 gene mutations in familial or sporadic forms of the affection associated with febrile seizures, and to search for an intervention SCN1A, SCN1B and GABRG2 as susceptible genes in these forms of epilepsies.
