Key result

The eNOS G894T and T-786C gene polymorphisms are significantly associated with coronary artery disease, with the G894T allelic variant showing an OR of 0.83 (p=0.004).

Why the study?

Are endothelial nitric oxide synthase (eNOS) gene polymorphisms associated with coronary artery disease?

Population

56 genetic association studies evaluating patients with coronary artery disease and controls

Comparison

Overview

eNOS variants may refine CAD genetic risk models in practice; confirms associations via pooled meta-analysis of candidate genes.

Are endothelial nitric oxide synthase (eNOS) gene polymorphisms associated with coronary artery disease?

P
Population
Meta-analysis of 56 genetic association studies evaluating the relationship between eNOS gene polymorphisms and coronary artery disease.
E
Exposure
Endothelial nitric oxide synthase (eNOS) gene polymorphisms (G894T, 4b/a, T-786C)
C
Comparator
Wild-type eNOS gene
O
Outcome
Coronary artery disease (CAD)

Main Result

Odds Ratio: 0.83

p-value: p=0.004

The eNOS G894T and T-786C gene polymorphisms are significantly associated with an increased risk of coronary artery disease, whereas the 4b/a variant is not.

Cite This Study

Jun-yan et al. (2010) conducted a meta-analysis in Coronary artery disease (CAD). eNOS gene polymorphisms (G894T, 4b/a, T-786C) vs. Absence of polymorphisms (wild type) was evaluated on Coronary artery disease (OR 0.83, p=0.004). The eNOS G894T and T-786C gene polymorphisms are significantly associated with coronary artery disease, with the G894T allelic variant showing an OR of 0.83 (p=0.004).
