[Study on the correlation of estrogen receptor gene polymorphism to bone mineral density of radius in Chinese Han postmenopausal women in Beijing].
Zhonghua Fu Chan Ke Za Zhi. 2001 Jan; 36(1):40-2.ZF

Abstract

OBJECTIVE

To investigate the distribution of estrogen receptor (ER) gene polymorphism in postmenopausal Han women in Beijing as well as its correlation with bone mineral density (BMD) of radius.

METHODS

Xba I, and Pvu II polymorphism of ER gene were studied by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) in 99 healthy postmenopausal Han women. BMD of distal (spongy bone) and proximal (compact bone) radius were determined by dual-energy X-ray absorptiometry (DEXA) as well. The relationship between BMD and polymorphism of ER gene was analyzed by variance analysis.

RESULTS

Pvu II polymorphism of ER gene is not associated with BMD of both sites of radius (P > 0.05); while Xba I polymorphism of ER gene is significantly associated with BMD spongy and compact bone of radius (P < 0.05). Women with XX genotype have the lowest BMD T-score of -1.55 +/- 0.37 for the compact and -2.54 +/- 0.38 for the spongy, and those with xx genotype have the highest BMD T-score of -0.95 +/- 0.24 for compact and -1.74 +/- 0.16 for spongy.

CONCLUSION

There is a significant correlation of Xba I polymorphism of ER gene with BMD of distal and proximal radius. It is indicated that the difference in ER genotypes among individuals might influence the development of osteoporosis.
