Association of body mass index and Parkinson disease
Domenighetti, Cloé; Sugier, Pierre-Emmanuel; Ashok Kumar Sreelatha, Ashwin; Schulte, Claudia; Grover, Sandeep; Portugal, Berta; Lee, Pei-ChenBackground and objectives: The role of body mass index (BMI) in Parkinson disease (PD) is unclear. Based on the Comprehensive Unbiased Risk Factor Assessment for Genetics and Environment in PD (Courage-PD) consortium, we used 2-sample Mendelian randomization (MR) to replicate a previously reported inverse association of genetically predicted BMI with PD and investigated whether findings were robust in analyses ...
Dairy intake and Parkinson's disease: a Mendelian randomization study
Domenighetti, Cloé; Sugier, Pierre‐Emmanuel; Ashok Kumar Sreelatha, Ashwin; Schulte, Claudia; Grover, Sandeep; Mohamed, Océane; Portugal, BertaBackground: Previous prospective studies highlighted dairy intake as a risk factor for Parkinson's disease (PD), particularly in men. It is unclear whether this association is causal or explained by reverse causation or confounding. Objective: The aim is to examine the association between genetically predicted dairy intake and PD using two-sample Mendelian randomization (MR). Methods: We genotyped a well-establ...
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...
