Abstract |
Previous studies suggested an importance of estrogen on bone mass and a relationship between polymorphism of the estrogen receptor (ER) gene and bone mineral density (BMD) in men. We investigated the association between BMD and ER gene polymorphism, PvuII and XbaI genotypes in the first intron of ER gene in a prospective study of 157 Korean young men, aged 25.3±3.7 years.
Areal BMD was measured by dual-energy X-ray absortiopmetry at the lumbar spine, femoral neck, Trochanter, Ward's triangle and femoral shaft in young healthy Korean men. ER genotype was determined by polymerase chain reaction (PCR) analysis of genomic DNA. The PCR products were digested with PvuII and XbaI.
The prevalence of PvuII gene polymorphisms was 19.1% for PP, 43.3% for Pp and 37.6% for pp, respectively, and that of XbaI was 5.1% for XX, 36.3% for Xx and 58.6% for xx, respectively. No significant association was found between BMD and either PvuII or XbaI genotypes, after adjustment for age and body mass index. Further analysis of ER polymorphisms according to Px haplotypes failed to demonstrate possible association with BMD.
These data do not support the hypothesis that there is an association between ER genotype and BMD in Korean young men.
