Abstract


OBJECTIVE
To examine the relationship between Osteoprotegerin gene polymorphisms, and bone mineral density (BMD).
METHODS
Restriction fragment length polymorphisms at the Osteoprotegerin A163G (promoter), G1181C (exon 1) gene site, and BMD at the lumbar spine and proximal femur were analyzed in 229 postmenopausal Korean women (81 normal, 111 osteopenic and 37 osteoporotic patients). BMDs were measured by DEXA.
RESULTS
The distribution of A163G and G1181C polymorphisms in all postmenopausal women was as follows: AA 54.6%, AG 37.1%, GG 8.3%; GG 52.4%, GC 38.0%, CC 9.6%, respectively. After adjusting for potential confounding factors such as age, BMI, and menopause duration, A163G polymorphism was significantly associated with BMD at the lumbar spine and G1181C polymorphism BMD at the trochanter in all postmenopausal women. A163G polymorphism was significantly associated with BMD at the lumbar spine in normal and osteoporotic patients, and BMD at the femur neck and wards triangle in normal patients. G1181C polymorphism was significantly associated with BMD at the femur neck in osteopenic and osteoporotic patients, and BMD at the wards triangle and trochanter in osteoporotic patients.
CONCLUSION
These findings suggest that osteoprotegerin gene polymorphisms may be an important contributor to the variation of BMD among postmenopausal Korean women.
