Your genome is your complete set of DNA. Initially, we won’t be sequencing all of your DNA but instead will specifically look at genetic variations mostly known to be common, but some rare in the population. We will use a DNA microarray to genotype ~650,000 genetic variations that allow us to capture information about >90% of the genome. As technology improves, the project or NIHR BioResource team may sequence all or part of your genetic code, to get improved coverage of rarer genetic variants. All your genetic data will be stored securely in order to allow us to improve our understanding of the development and treatment of eating disorders, as well as other health studies, as part of the NIHR BioResource.
