Abstract

The association between the A1330V polymorphism of the low-density lipoprotein receptor-related protein 5 gene (LRP5) with bone mineral density (BMD) has been studied, but results have been mixed. Accordingly, the authors performed a meta-analysis on studies on the association between the A1330V LRP5 polymorphism and BMD. Appropriate studies were identified using MEDLINE and by manual searching. A total of 7 separate comparisons were considered in this meta-analysis. Individuals with the AA genotype showed significantly higher lumbar BMD than those with the AV/VV or VV genotype. Weighted mean differences (WMDs) were 0.147 g/cm2 (95% confidence interval [CI] 0.069-0.224, P < 0.001) and 0.182 g/cm2 (95% CI 0.024-0.340, P = 0.024) without between-study heterogeneity for AA versus AV/VV and AA versus VV, respectively. Six studies analyzed femur neck (FN) BMD. Individuals with the AA genotype had a significantly higher FN BMD than those with the AV/VV genotype (WMD = 0.165 g/cm2, 95% CI = 0.087-0.215, P < 0.001), without between-study heterogeneity. Trochanter BMD was measured in three studies. Results showed that subjects with the AA genotype tended to have higher BMD than patients with the AV or VV genotype (WMD = 0.136 g/cm2, 95% CI = -0.002 to 0.274, P = 0.053). In conclusion, this meta-analysis shows that the LRP5 A1330V polymorphism is associated with BMD, and that individuals with the AA genotype have a higher BMD than those with the AV/VV or VV genotype.
