Angiotensin converting enzyme gene insertion/deletion polymorphism in patients with polycystic ovary syndrome

Objective. The aim of this study is to investigate the relevance of polymorphism in angiotensin converting enzyme (ACE) gene insertion/deletion (I/D) polymorphism to the pathophysiology of polycystic ovary syndrome (PCOS). Subjects and methods. Thirty patients with PCOS by Rotterdam consensus criteria and 33 control subjects were prospectively investigated. ACE gene amplification of DNA was performed by polymerase chain reaction. Homeostatic model assessment (HOMA-IR) was applied. Results. Compared to controls, ACE gene DD genotype and D allele were observed more frequently in PCOS (63% vs. 46% for DD genotype and 75% vs. 67% for D allele) (p>0.05). Body mass index, fasting glucose and insulin levels, HOMA-IR index and total testosterone levels were higher in PCOS group (p0.05). No significant differences were observed in the genotype and allele distributions between cases and control groups. HOMA-IR index was significantly higher in patients with PCOS with DD genotype than those with II genotype (p
