Abstract
Polycystic ovary syndrome (PCOS) is one of the most common endocrine diseases in women. In recent years, the effects of vitamin D receptor (VDR) gene variants and VitD3 levels on clinical features of PCOS have been frequently described. In this study, we aimed to determine the relationship between VDR ApaI, TaqI and Cdx2 gene variants and VitD3 levels in PCOS patients. Patients were divided into two groups: BMI<25 and BMI≥25. VDR genotypes were determined by real-time polymerase chain reaction (PCR) and serum VitD3 levels were examined by ELISA. We observed that frequencies of the Apa1 AC genotype, C allele and Cdx2 T allele are increased in the BMI≥25 group compared to BMI<25 group. Also, the ApaI C allele, Taq1 AA genotype and A allele, Cdx2 CC genotype and C allele are associated with increased triglyceride, total cholesterol, LDL-cholesterol levels in patients with BMI≥25. When examining the relationship between VitD3 levels and clinical profiles in all PCOS patients, regardless of BMI distinction, it is determined that there is a positive correlation between LDL-cholesterol and ftestosterone levels. The present findings suggest that VDR variants are one of the most important risk factors for PCOS, especially for patients with BMI≥25.
