Assessment of the impact of VDR polymorphisms on selected hormonal, metabolic and mineral balance markers in young women with hyperandrogenism.

Objectives: Hyperandrogenism is a frequently recognized endocrine imbalance in which there is excessive production of androgens. The purpose of the study was to investigate the impact of vitamin D receptor (VDR) gene polymorphisms on chosen bone metabolism and biochemical parameters in women with hyperandrogenism.

Material And Methods: Eighty young females with hyperandrogenism were enrolled in the study, in whom selected parameters of bone turnover, endocrine and metabolic parameters were determined. Two polymorphisms of the VDR gene were analyzed: rs731236 (TaqI) and rs1544410 (BsmI), using real-time polymerase chain reaction (PCR). Statistical tests were performed in this research with the program SPSS Statistics 17.0 for Windows.

Results: The rs731236 and rs1544410 polymorphisms of the VDR gene turned out to be statistically significantly related to the concentration of insulin determined in the 60 'glucose tolerance test. There was no relationship between the studied polymorphisms of the VDR gene and the determined parameters of bone metabolism and other biochemical parameters.

Conclusions: The research presented that VDR gene variants may influence disturbances in carbohydrate metabolism in young women with hyperandrogenism.
