It has been suggested that the estrogen receptor alpha (ERα) and vitamin D receptor (VDR) genes as possibly implicated in reduced bone mineral density (BMD) in osteoporosis. The present study investigated the relation of ERα PvuII/XbaI polymorphisms and VDR FokI/TaqI polymorphisms with BMD in Turkish postmenopausal women. Eighty-one osteoporotic and 122 osteopenic postmenopausal women were recruited. For detection of the polymorphisms, polymerase chain reaction-restriction fragment lenght polymorphism techniques have been used. BMD was measured at the lumbar spine and hip by dual-energy X-ray absorptiometry. Distributions of ERα (PvuII dbSNP: rs2234693, XbaI dbSNP: rs9340799) and VDR genotypes (FokI dbSNP rs10735810, TaqI dbSNP: rs731236) were similar in study population. Although overall prevalence of osteoporosis had no association with these genotypes, the prevalence of decreased femoral neck BMD values were higher in the subjects with ERα PvuII "PP" and ERα XbaI "XX" genotypes than in those with "Pp/pp" genotypes and "xx" genotype, respectively (P < 0.05). Furthermore, subjects with VDR FokI "FF" genotype had lower BMD values of femoral neck and total hip compared to those with "Ff" genotype (P < 0.05). In the logistic regression analysis, we confirmed the presence of relationships between the VDR FokI "FF" genotypes, BMI ≤ 27.5, age ≥ 55 and the increased risk of femoral neck BMD below 0.8 value in postmenopausal women. The present data suggests that the ERα PvuII/XbaI and VDR FokI polymorphisms may contribute to the determination of bone mineral density in Turkish postmenopausal women.
