To clarify the relationship between them, we performed a meta-analysis.Methods A comprehensive literature search was conducted to examine all the eligible studies of VDR BsmI polymorphism and OC risk. Odds ratios (OR) with 95% confidence intervals (95% CI) were used to assess the strength of this association.Results Seven separate comparisons consisting of 1977 OC cases and 2832 healthy controls were included in our meta-analysis. The pooled analyses showed no significant association between VDR BsmI G/A polymorphism and OC in all of the comparisons (AA vs GG: OR, 1.01; P = 0.919; AG vs GG: OR, 1.12; P = 0.087; AG + AA vs GG: OR, 1.10; P = 0.146; AA vs AG + GG: OR, 0.96; P = 0.629). However, subgroup analysis showed a significant contribution of the dominant inheritance model to OC development in the European group: AG + AA vs GG (OR, 1.43; P = 0.029); AG vs GG (OR, 1.46; P = 0.031).Conclusions Vitamin D receptor BsmI G/A gene variant might be a moderate risk factor of OC development in the European population instead of North America or Asian population. %U https://ijgc.bmj.com/content/ijgc/23/7/1178.full.pdf
