Abstract:
OBJECTIVETo investigate the association of calcitonin receptor (CTR) gene polymorphism with bone mineral density (BMD) in premenopausal and postmenopausal women.
METHODSCTR genotypes were determined by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) in 184 premenopausal women and 199 postmenopausal women in Shanghai area. BMD at lumbar spine (L2-4) and femoral neck (FN) were measured by dual-energy X-ray absorptiometry (DEXA).
RESULTSThe distribution of CTR genotypes in 383 Shanghai women were CC genotype 83.8%, TC genotype 14.6%, TT genotype 1.6%, respectively. BMD at FN of CC genotype was significantly higher than TC and TT genotypes (P < 0.01) in postmenopausal women. But there was no difference in BMD of different CTR genotypes in premenopausal women. Multiple regression analysis showed that CTR genotypes were associated with FN BMD in postmenopausal women (P < 0.05).
CONCLUSIONSThe polymorphism of CTR gene was associated with BMD in postmenopausal women.
