Objectives: To find out the association between Thrombomodulin gene polymorphism (C1418T) with coronary artery disease in population of Karachi, Pakistan.

Methods: This case-control study was conducted in Tabba Heart Institute in collaboration with the National Institute of Blood Diseases, Karachi. We compared C/T dimorphism in 92 cases with 90 control subjects by allele-specific amplification. The results of PCR were confirmed by Gene sequencing. All the laboratory methods were strictly in compliance with the international standards. All variables that were either statistically significant in the univariate analyses or potentially important with respect to prevention or biologically relevant variables were included in logistic-regression analyses. Potential confounding was assessed with the use of multivariate models adjusted for participant’s characteristics and other major risk factors for coronary artery disease. All reported p values are two-tailed, with statistical significance at p value <0.05.

Results: The frequency of CC, C/T and TT genotype was 81 (90%), 6 (6.7%) 3 (3.3%) in controls and 67 (72.8%), 20 (21.7%) and 5 (5.4%) in cases respectively. In cases group the CT/TT genotypes were found to be significantly highly represented among the patients with coronary artery diseases when compared with control group (p-value 0.009).

Conclusion: TM C1418T polymorphism emerges as a risk marker in Coronary Artery Disease patients in the population of Karachi, Pakistan.
