ASSOCIATION BETWEEN INSERTION/DELETION POLYMORPHISM OF THE ANGIOTENSIN-CONVERTING ENZYME GENE AND CORONARY ARTERY DISEASE IN BOSNIAN POPULATION

One of the genes considered as a risk factor for coronary artery disease (CAD) is the angiotensin-converting enzyme (ACE) gene. Many studies have been published regarding the relation between the ACE gene insertion/deletion (I/D) polymorphism and CAD. However, studies have provided controversial results. To explore this further in the population of Bosnia and Herzegovina, we compared the ACE I/D genotypes and alleles distribution between two groups: 100 CAD patients and 100 healthy control subjects. The higher distribution of DD genotype (47.0%) and D allele (65.5%) were found in CAD patients compared to controls (DD 34.0%; D allele 51.0%). Genotype odds ratio, (DD + ID) on the II, was 2.471 (1.252 – 4.876; 95% CI; p < 0.05). This leads to the conclusion that the DD genotype of the ACE I/D polymorphism affects the risk for development of coronary artery disease in Bosnian population
