The "a" type allele of the endothelial nitric oxide synthase (eNOS) gene may increase the risk of coronary artery ectasia (CAE). This genetic factor warrants further investigation in CAE pathogenesis.
Area of Science:
- Cardiovascular Genetics
- Molecular Cardiology
Background:
- Pathogenesis and genetics of coronary artery ectasia (CAE) remain largely unknown.
- Endothelial nitric oxide synthase (eNOS) gene intron 4a/b polymorphism is investigated as a potential factor in CAE.
Purpose of the Study:
- To investigate the association between eNOS gene intron 4a/b polymorphism and coronary artery ectasia.
- To explore the genetic underpinnings of CAE development.
Main Methods:
- Study included 30 patients with CAE and 30 controls with normal coronary arteries.
- Agarose gel electrophoresis was employed to determine eNOS gene polymorphisms.
- Coronary angiography was used for diagnosis and assessment of coronary artery disease (CAD).
Main Results:
- The "a" allele of the eNOS gene was significantly more frequent in patients with CAE compared to controls (P=0.027).
- While eNOS phenotypes differed between groups, statistical significance was not reached for all comparisons (P=0.08).
- Univariate analysis showed a correlation between eNOS polymorphism and CAE, which diminished after adjusting for confounders.
Conclusions:
- The presence of the "a" type allele of the eNOS gene may be associated with an elevated risk of developing coronary artery ectasia.
- Further research is needed to elucidate the role of eNOS gene polymorphism in CAE pathogenesis.
