Atherosclerosis: analysis of the eNOS (T786C) gene polymorphism.

Area of Science:

• Cardiovascular Medicine
• Genetics
• Molecular Biology

Background:

• Coronary arteriosclerotic disease is a leading cause of mortality.
• Atherosclerosis involves arterial narrowing and thrombosis, leading to severe clinical events.
• Nitric oxide, regulated by the eNOS gene, plays a crucial role in vascular health.

Purpose of the Study:

• To investigate the association between the T786C polymorphism of the eNOS gene and coronary arteriosclerotic disease.
• To determine if specific genotypes (TT, TC, CC) correlate with the presence of atherosclerosis.
• To analyze the influence of gender and smoking on this potential association.

Main Methods:

• Genotyping of the T786C polymorphism in 297 patients with diagnosed atherosclerotic disease and controls.
• Comparison of genotype frequencies between case and control groups using chi-square and G-tests.
• Stratified analysis based on gender and smoking status.

Main Results:

• The TC genotype was more prevalent in both groups, but without statistical significance.
• No significant differences were observed in genotype distributions (TC/TT vs. CC) between cases and controls.
• Gender and smoking status did not significantly alter the observed genotype associations.

Conclusions:

• The T786C polymorphism of the eNOS gene did not show a statistically significant association with coronary arteriosclerotic disease in this cohort.
• Despite a suggested tendency for the T allele, the study did not confirm a link between this polymorphism and atherosclerosis.
• Further research with larger sample sizes may be needed to clarify the role of eNOS polymorphisms in cardiovascular disease.
