Insights
The thrombospondin-1 (TSP-1) N700S gene variant is present in Chinese populations but at low frequencies. This TSP-1 N700S polymorphism is not associated with coronary artery disease (CAD) or acute myocardial infarction (AMI) risk.
Area of Science:
- Genetics
- Cardiovascular Disease Research
- Molecular Biology
Context:
- Coronary artery disease (CAD) is a leading cause of mortality worldwide.
- Genetic polymorphisms are increasingly recognized as contributing factors to complex diseases like CAD.
- Thrombospondin-1 (TSP-1) plays a role in cardiovascular health, making its genetic variants of interest.
Purpose:
- To investigate the association between the thrombospondin-1 (TSP-1) gene A8831G (N700S) polymorphism and the risk of coronary artery disease (CAD).
- To determine if the TSP-1 N700S polymorphism is a risk factor for acute myocardial infarction (AMI).
Summary:
- A case-control study involving 178 CAD patients (55 with AMI) and 158 healthy controls was conducted.
- The TSP-1 N700S polymorphism was analyzed using polymerase chain reaction and restriction fragment length polymorphism.
- No significant differences in genotype or allele frequencies were observed between CAD/AMI groups and controls, indicating no association.
Impact:
- The TSP-1 N700S polymorphism, while present in the Chinese Zhejiang Han population, occurs at a much lower prevalence than in Western populations.
- This specific TSP-1 N700S variant is unlikely to be a significant genetic risk factor for CAD or AMI in this population.
- Findings contribute to understanding the genetic landscape of cardiovascular disease risk in diverse ethnic groups.
Objective:
To investigate the association of thrombospondin-1 (TSP- 1) gene A8831G (N700S) polymorphism with coronary artery disease (CAD).
Methods:
This study was conducted with a case-control design including 178 patients with CAD (55 AMI) and 158 healthy subjects. The TSP-1 N700S polymorphism was determined by polymerase chain reaction and restriction fragment length polymorphism analysis.
Results:
No significant difference of the AG genotype in CAD group and control group (1.7% compared with 0.6%, P=0.375) was detected. None of the homozygotes was detected for the G allele. The prevalence of the G allele was not significantly different between CAD group and controls (0.8% compared with 0.3%, P=0.376). No significant difference of the AG genotype in AMI group and control group (3.6% compared with 0.6%, P=0.104). The prevalence of G allele was not significantly different between AMI patients and controls (1.8% compared with 0.3%, P=0.364).
Conclusion:
There are TSP-1 N700S polymorphisms in Chinese Zhejiang Han people, but the TSP-1 N700S variant shows a much lower prevalence compared with Western populations and may be not a potential risk for CAD and AMI.
