Role of SIRT-1 rs7895833 polymorphism in susceptibility to polycystic ovary syndrome

Abstract

Introduction: Sirtuin 1 is a protein deacetylase that plays an important role in many cellular processes. The serum sirtuin 1 levels are higher in the polycystic ovary syndrome (PCOS) patients than the healthy subjects. The aim of this study was to assess the role of SIRT-1 rs7895833 polymorphism in the susceptibility of PCOS. Methods: This case-control study was done on 456 Iranian women from March to February 2015. Blood samples were collected from 274 women with PCOS and 182 age matched (±5) healthy women at Shiraz Ghadir Mother and Child Hospital. After DNA extraction, SIRT1 rs7895833 genotype determination was done by Tetra-ARMS PCR. Data analysis was performed by SPSS version 18. Results: In the dominant model for G allele (AG+GG vs. AA), AG+GG genotypes in SIRT1 rs7895833 gene polymorphism was associated with the increased risk of PCOS (OR: 2.01, %95CI:1.32-3.24, P=0.002). Moreover, there was a significant association between the G allele and PCOS (OR: 1.45, %95CI:1.10-1.91, P=0.008). Conclusion: The results showed a possible association between SIRT1 rs7895833 gene polymorphism and susceptibility to PCOS
