Common variants in Alzheimer's disease and risk stratification by polygenic ris...
de Rojas, Itziar; Moreno-Grau, Sonia; Tesi, Niccolo; Grenier-Boley, Benjamin; Andrade, Victor; Jansen, Iris E.; Pedersen, Nancy L.; Stringa, NajadaGenetic discoveries of Alzheimer's disease are the drivers of our understanding, and together with polygenetic risk stratification can contribute towards planning of feasible and efficient preventive and curative clinical trials. We first perform a large genetic association study by merging all available case-control datasets and by-proxy study results (discovery n = 409,435 and validation size n = 58,190). Her...
Genetic and lifestyle risk factors for MRI-defined brain infarcts in a populati...
Chauhan, Ganesh; Adams, Hieab H.H.; Satizabal, Claudia L.; Bis, Joshua C.; Teumer, Alexander; Sargurupremraj, Muralidharan; Hofer, EdithObjective: To explore genetic and lifestyle risk factors of MRI-defined brain infarcts (BI) in large population-based cohorts. Methods: We performed meta-analyses of genome-wide association studies (GWAS) and examined associations of vascular risk factors and their genetic risk scores (GRS) with MRI-defined BI and a subset of BI, namely, small subcortical BI (SSBI), in 18 population-based cohorts (n = 20,949) f...
