Understanding the genetics of Alzheimers disease (AD) is one of the best ways of improving our knowledge of the diseases underlying pathophysiological processes. Indeed, genetic factors account for up to 70% of the attributable risk in common forms of AD. The advent of genomic approaches has led to the characterization of 26 genetic determinants. However, it has been estimated that less than 50% of the AD genetic attributable risk has been cha- racterised. Substantial additional efforts are thus still needed to explore the AD genetic landscape. However, exhaustively characterising the genetic factors of AD will require analysing large populations of cases and controls. Our objective is thus to significantly increase the genera- tion of genetic data via the creation of a European Alzheimers Disease DNA BioBank (EADB). Our project will collate 31,911 AD cases and 40,802 controls from 11 countries. This initiative will increase the number of AD samples available for genetic studies in Europe by more than 4-fold and worldwide by almost 2-fold. In parallel, the EADB will collect DNA samples from Europes largest longitudinal cohort of cases suffering from mild cognitive impairment (9,109 cases), with a view to identifying ge- netic markers that modulate the rate of disease progression and cognitive decline.
