Population Genomic Diversity of France

"Volunteers who agreed to participate will have to collect their saliva with the self-collection device. They will then send back their saliva sample and a dated and signed copy of the informed consent form in the pre-paid return envelope.~All DNA of the saliva samples will be automatically extracted, then DNA samples will be genotyped and 4,000 of them will be sequenced.~The genotyping will consist of measurement of general genetic variation, including the Single Nucleotide Polymorphisms. The SNP genotyping will be carried out using Illumina high density chips, in CNRGH production platform.~A subset of 4,000 individuals will be selected to provide a homogeneous geographic coverage and to avoid inclusion of related individuals who will share large genomic regions. Sequencing will be performed in order to reach a mean coverage of 30X for each sample and a minimum of 25X mean coverage.~Finally, a bioinformatics analysis will be performed on sequencing data."
