Genetic associations between modifiable risk factors and Alzheimer disease
Luo, Jiao; Thomassen, Jesper Qvist; Bellenguez, Céline; Grenier-Boley, Benjamin; de Rojas, Itziar; Castillo, Atahualpa; Parveen, KayenatImportance: An estimated 40% of dementia is potentially preventable by modifying 12 risk factors throughout the life course. However, robust evidence for most of these risk factors is lacking. Effective interventions should target risk factors in the causal pathway to dementia. Objective: To comprehensively disentangle potentially causal aspects of modifiable risk factors for Alzheimer disease (AD) to inspire n...
Association of rare APOE missense variants V236E and R251G with risk of Alzheim...
Le Guen, Yann; Belloy, Michael E.; Grenier-Boley, Benjamin; de Rojas, Itziar; Castillo-Morales, Atahualpa; Jansen, Iris; Nicolas, AudeImportance: The APOE ε2 and APOE ε4 alleles are the strongest protective and risk-increasing, respectively, genetic variants for late-onset Alzheimer disease (AD). However, the mechanisms linking APOE to AD-particularly the apoE protein's role in AD pathogenesis and how this is affected by APOE variants-remain poorly understood. Identifying missense variants in addition to APOE ε2 and APOE ε4 could provide crit...
Analysis of shared heritability in common disorders of the brain
Anttila, Verneri; Bulik-Sullivan, Brendan; Finucane, Hilary K.; Walters, Raymond K.; Bras, Jose; Duncan, Laramie; Escott-Price, ValentinaDisorders of the brain can exhibit considerable epidemiological comorbidity and often share symptoms, provoking debate about their etiologic overlap. We quantified the genetic sharing of 25 brain disorders from genome-wide association studies of 265,218 patients and 784,643 control participants and assessed their relationship to 17 phenotypes from 1,191,588 individuals. Psychiatric disorders share common varian...
