Recognition of different genetic variants underlying osteoporosis would make it possible to introduce individual, symptomatic treatment as well as early prophylaxis of osteoporosis. The aim of the study was to evaluate the frequency of the rs2275913 (−197G > A) polymorphism of the IL-17gene and assess the relation of this polymorphism with the clinical parameters of the osseous turnover and degree of the postmenopausal osteoporosis. The study included 800 women of postmenopausal (505) and reproductive (295) ages throughout the Wielkopolska region in Poland. The postmenopausal group included women with osteoporosis and osteopenia, and those who were healthy. Women at reproductive age were healthy. The frequency of the tested gene polymorphism was evaluated in the group where bone mineral density (BMD) was marked and in the control group. The results obtained showed that the T-score in the female population with osteopenia was remarkably lower in women showing the GG genotype of -197G > A polymorphism of IL-17gene compared to patients with heterozygous GA genotype. It has been shown that the BMD value for L2–L4 YA in the evaluated female population with osteoporosis is significantly higher in women with the GA genotype of -197G > A polymorphism of IL-17gene compared to women with the GG genotype (76.32% versus 59.93%, P<0.05). It has also been noted that the BMD value for L2 to L4 AM in patients with the GG genotype was lower than in women with the AA genotype (69.73% versus 80.88%, P<0.05). It is suggested that the -197G > A polymorphism of the IL-17 gene may be considered as a genetic factor of postmenopausal osteoporosis. This polymorphism can influence the bone mineral density and T-score value in young women and postmenopausal women.
