BACKGROUND: Polycystic ovary syndrome (PCOS) is an endocrine disorder exhibiting variable age at onset of clinical features allied with complex diseases in the later life. ACE is a pleiotropic molecule associated with various pathophysiological functions. The present study was aimed to establish the frequency of ACE I/D gene polymorphism in patients and controls and to assess the influence of this polymorphism on anthropometric and various clinical features of the condition. METHODS: ACE I/D genotyping was carried out in 259 PCOS patients and 315 healthy ultrasound scanned women of South Indian origin. RESULTS: The distribution of DD, ID and II genotypes in patients was 39, 37 and 24 %, whereas in the controls it was 31, 51 and 18 % respectively. Significant difference was observed in the genotypic frequency distributions between the patients and controls, however the allelic frequencies did not vary between the groups (p>0.05). Quartile analysis revealed preponderance of DD genotype in the first two quartiles and a linear increase of II genotype from first to the last quartiles. Further, Multiple Logistic regression analysis revealed significant association of ACE I/D gene polymorphism with acanthosis and age at onset (AAO) of the syndrome (p<0.05). CONCLUSION: The present study is the first report to highlight the predisposing role of DD and protective role of ID genotype towards PCOS. Patients with single or double dose of D allele may develop PCOS symptoms at an early age and also significantly associated with acanthosis, a marker of insulin resistance.
