rs641738C>T near MBOAT7 is associated with liver fat, ALT and fibrosis in NAFLD: A meta-analysis

Kevin Teo, +121 more
TL;DR: This study validates rs641738C>T near MBOAT7 as a risk factor for the presence and severity of NAFLD in individuals of European descent and takes data from over 40 published studies to find that this variant is linked to more severe fatty liver disease.
Journal ArticleDOI

Genetic variation associated with circulating monocyte count in the eMERGE Network

David R. Crosslin, +70 more
TL;DR: A joint and ancestry-stratified genome-wide association analyses to identify variants specifically associated with monocyte count in 11 014 subjects in the electronic Medical Records and Genomics Network identify novel associations in the chromosome 16 interferon regulatory factor 8 gene.
Journal ArticleDOI

Stroke genetics informs drug discovery and risk prediction across ancestries

Aniket Mishra, +551 more
- 04 Jan 2022 - 
TL;DR: In this article , a cross-ancestry GWAS meta-analyses of 110,182 patients who have had a stroke (five ancestries, 33% non-European) and 1,503,898 control individuals, identify association signals for stroke and its subtypes at 89 (61 new) independent loci: 60 in primary inverse-variance-weighted analyses and 29 in secondary meta-regression and multitrait analyses.
Journal ArticleDOI

Electrocardiographic and clinical predictors of acute myocardial infarction in patients with unstable angina pectoris.

TL;DR: Electrocardiographic and clinical variables can help immediately identify those at high risk for AMI at presentation and a prediction rule was developed that was validated in this cohort of patients.
Journal ArticleDOI

Factor VII Gene Polymorphism, Factor VII Levels, and Prevalent Cardiovascular Disease The Framingham Heart Study

TL;DR: In the Framingham Heart Study, the Arg/Gln polymorphism was significantly associated with factor VII antigen levels, and the strength of the association suggests that genetic variation plays an important role in determining factor VII levels.
