Association between insertion/deletion polymorphism of the ace gene with risk of hypertension

This study conducted an initial investigation into the association between ACE gene insertion/deletion (I/D) polymorphisms (rs1799752) and hypertension in the Republic of Srpska, Bosnia and Herzegovina. The study featured two distinct groups, each with 100 subjects, systematically categorized based on hypertension status and gender. DNA was extracted, PCR-amplified, and analyzed by gel electrophoresis. Results revealed a higher prevalence of the DD genotype and the D allele in the hypertensive group, although statistical significance was not observed. The II genotype occurred in 18% of the hypertension group and 21% in the control group. A significant difference was found in allele I frequencies between the two groups (p=0.004), with no gender-related variations in ACE alleles. The limited sample size may have constrained the ability to detect statistically significant differences. The odds ratio for the (DD + ID) genotype compared to II was 1.2110 (95% CI: 0.6006 to 2.4418; p=0.5927), indicating no statistical significance. Furthermore, no significant associations were identified between ACE genotypes and alleles and gender. In summary, this preliminary study suggests a potential trend towards a higher prevalence of the ACE gene D allele and DD genotype in hypertensive individuals. However, due to the small sample size, these associations did not achieve statistical significance in this population. Larger-scale investigations are needed for more definitive insights into the relationship between ACE gene polymorphisms and hypertension.
