Abstract

Deregulation of the renin–angiotensin system (RAS) plays an important role in suicide. Angiotensin converting enzyme (ACE) gene is a key component in this system. The relationship between insertion/deletion (I/D) polymorphism of ACE gene with suicide attempt (SA) is controversial. According to previous studies, allele D in this polymorphism has been considered as a potential risk factor for suicide. However, no study has been conducted in Iran to investigate this matter. This case–control study has focused on investigating the association of ACE I/D polymorphism (rs1799752) with SA in an Iranian population. The frequency of genotypes was 14% for II, 55% for ID, and 31% for DD in the case group (100 persons), and 18% for II, 74% for ID, and 8% for DD in control group (100 persons). Results show there was a significant difference in the distribution of ACE I/D polymorphism genotypes in men with SA compared to controls, as well as in women with SA compared to controls. Also, there was a significant association between DD genotype and the risk of SA compared to II genotype as reference. The severity of depression was significantly different between DD and II genotypes in SA group. According to the results, we suggest that the presence of DD genotype is possibly associated with an increased risk of SA. Maybe part of that is related to severity of depression in DD genotypes carriers of ACE I/D polymorphism. © 2020, Springer Science+Business Media, LLC, part of Springer Nature.
