Objective: to study an association of leptin (LEP) A19G polymorphism and leptin receptor (LEPR) Gln223Arg AND Lys109Arg polymorphisms with the predilection for postmenopausal osteoporosis (OP). Subjects and methods. PCR analysis was used to examine the polymorphisms among 428 women (254 patients with OP and 174 healthy women).The anthropometric, densitometric, and biochemical markers of bone remodeling and standard clinical and biochemical parameters were studied. Results. Statistically significant differences were found in the distribution of the genotypes of LEP A19G polymorphism between the women with OP and the controls (χ 2 = 9.41; p = 0.009). In the patients with OP, the 19GG genotype frequency was significantly higher than that in the controls [OR = 2.0;
