Investigation of the monocyte diapedesis-related LFA-1 and JAM-A gene variants in Turkish coronary heart disease patients.


ABSTRACT:

Background

LFA-1/JAM-A interaction plays a significant role in early steps of leukocyte transendothelial migration (diapedesis) which takes part in atherosclerosis pathogenesis. In this population-based case-control study, the frequencies of JAM-A rs790056 and LFA-1 rs8058823 gene polymorphisms in patients with coronary heart disease (CHD) and healthy subjects were investigated and the correlations between the different genotypes and cardiovascular risk factors were analyzed.

Methods

The JAM-A and LFA-1 genotypes were determined in 153 patients with CHD and 124 controls by PCR-RFLP assay.

Results

In CHD patient group, the frequency of JAM-A rs790056 TT genotype and the frequency of T allele were higher when compared with the control group (p = 0.03 and p = 0.007,respectively). In patient groups, the frequency of LFA-1 rs8058823 AA genotype was higher (p = 0.000), and the frequency of AG genotype was lower when compared with the control group (p = 0.031). In the control group, LFA-1 rs8058823 G allele carriers had higher SBP than subjects with AA genotype (p = 0.038), whereas in the CHD patient group, G allele carriers had lower DBP than subjects with AA genotype (p = 0.007). The multivariate logistic regression analysis confirmed that the JAM-A rs790056 TT genotype (OR = 2.472, p = 0.045) and LFA-1 rs8058823 AA genotype (OR = 6.751, p = 0.000) were risk factors for CHD development.

Conclusion

These results suggest that the wild type genotypes and alleles of JAM-A rs790056 (TT genotype and T allele) and LFA-1 rs8058823 (AA genotype and A allele) were found to be risk factors for CHD, whereas rare genotypes and alleles were found to be higher in healthy controls thus being protective.
