[Association of Toll-like receptor 2 and 4 gene polymorphisms with risk of coronary atherosclerotic artery disease in Hunan Han population].

To explore Toll-like receptor 2 (TLR2) and TLR4 polymorphism in Han people from Hunan region and its association with coronary atherosclerotic heart disease.

Methods

Sanger sequence and statistical analysis were performed to identify the polymorphism of TLR2 and TLR4 genes in 347 unrelated Hunan Han subjects, including 180 healthy people (control group) and 167 patients with coronary atherosclerotic heart disease (coronary atherosclerotic heart disease group).

Results

There was no significant difference in the genotype frequency and allelic frequency for TLR2 SNP2258G>A and TLR4 SNP896A>G between the 2 groups (P>0.05), while there was significant difference in the TLR4 SNP1196C>T between the 2 groups (P<0.05).

Conclusion

TLR4 SNP1196C>T polymorphism is associated with coronary atherosclerotic heart disease in Chinese Han populationin in Hunan region.
