The effect of eight different gene polymorphisms on osteopenia and osteoporosis in the Turkish population.

OBJECTIVE

Bone mineral density is affected by many gene regions. Osteoporosis is a disease that occurs due to decreased bone mineral density and has a polygenetic multifactorial pathogenesis. The aim of this study was to examine the effect of gene variants in eight gene regions related to bone mineral density in patients diagnosed with osteopenia or osteoporosis.

METHODS

A total of 60 patients diagnosed with osteoporosis, 50 patients diagnosed with osteopenia, and 40 healthy volunteers (control group) were included in the study. Collagen type I alpha 1 1997G/T, estrogen receptor α PvuII, estrogen receptor α XbaI, vitamin D receptor BsmI, lactase gene, osteoprotegerin G209A, osteoprotegerin T245G, and interleukin-6 G174C gene variants were analyzed.

RESULTS

No important difference was found in the distribution of collagen type I alpha 1 1997G/T, estrogen receptor α PvuII, estrogen receptor α XbaI, vitamin D receptor BsmI, lactase gene T13910C, osteoprotegerin T245G, and interleukin-6 G174C gene variants between groups. A significant difference was detected between the distribution of osteoprotegerin G209A gene variants in the patient groups and the distribution of osteoprotegerin G209A gene variants in the control group. On the other hand, no important difference was detected in the distribution of osteoprotegerin G209A gene variants between patient groups.

CONCLUSION

The osteoprotegerin G209A gene variant may be associated with the risk of osteopenia and osteoporosis in the Turkish population. Other gene variants analyzed that affect bone mineral density were not associated with the risk of osteopenia and osteoporosis.
