    Abstract:
    OBJECTIVE: To investigate the prevalence of vitamin D receptor (VDR) gene polymorphism in pre-menopausal women in Guangzhou and study its relationship with bone mineral density(BMD). METHODS: The genotypes of VDR gene in 193 per-menopausal women in Guangzhou were analyzed by polymerase chain reaction-restriction fragment length polymorphism. BMD of the lumbar spine, femoral neck, greater trochanter and Ward's triangle were measured by dual-energy X-ray absorptiometry. RESULTS: In the 193 subjects, 120 (66.2%) were identified as VDR bb genotype, 64 (33.2%) as Bb, and 9 (4.6%) as BB. The b allele frequencies reached 78.76%, and B allele frequencies was 21.24%. The distribution followed the Hardy-Weinberg equilibrium. No significant difference was found in BMD among the subjects with different genotypes. CONCLUSION: VDR genotype is not related to BMD, and VDR polymorphism can not be used as a genetic marker for predicting the risk of osteoporosis in pre-menopausal women in Guangzhou.
