Abstract
Primary osteoporosis is a common health problem in postmenopausal women. This study aimed to detect the association of the g.19074G>A genetic variant in the osteoprotegerin gene (OPG) with bone mineral density (BMD) and primary osteoporosis. The created restriction site-polymerase chain reaction method was used to investigate the g.19074G>A genetic variant. The BMD of the femoral neck hip, lumbar spine (L2-4), and total hip were assessed by dual-energy X-ray absorptiometry (DEXA) in 856 unrelated Chinese postmenopausal women. We found significant differences in the BMDs of the femoral neck hip, lumbar spine (L2-4), and total hip among different genotypes; individuals with the GG genotype had significantly higher BMDs than those with the GA and AA genotypes (P < 0.05). Our results indicated that the A allele was an increased risk factor for primary osteoporosis and the g.19074G>A genetic variant of the OPG gene was associated with BMD and primary osteoporosis in Chinese postmenopausal women.
