The relationship between the g.27450A>T genetic variant of OPG gene and osteoporosis in Chinese postmenopausal women

Abstract The objective of this study is to evaluate the relationship between the g.27450A>T genetic variant of osteoprotegerin ( OPG ) gene and osteoporosis in Chinese postmenopausal women. A total of 886 subjects were enrolled in this study. The femoral neck hip, lumbar spine (L 2–4 ), and total hip bone mineral density (BMD) were detected by dual-energy X-ray absorptiometry (DEXA). The genotyping of the g.27450A>T genetic variant of OPG gene was investigated by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) and DNA sequencing methods. Significant differences in the femoral neck hip, lumbar spine (L 2–4 ), and total hip BMD among different genotypes were found, and the subjects with AA genotype were significantly higher than those of AT and TT genotypes (P  T genetic variant of OPG gene has potential relationship with BMD and osteoporosis in Chinese postmenopausal women.
