BACKGROUND AND AIMS: Polymorphisms in Interleukin-6 (IL6) and its receptor (IL6R) have been associated with bone mineral density. In this work, the G-174C and G-572C polymorphisms in IL6, G-208A, and Asp358Ala in IL6R were analyzed in Mexican women with hip fracture. METHODS: Postmenopausal Mexican women (60 years or over) with hip fragility fracture (77.97 ± 8 years) and without hip fracture (70.5 ± 7.02 years) were genotyped by real-time PCR. RESULTS: The rs1800796 GG genotype was associated with low risk of fracture (p = 0.05), while GC genotype was associated with high risk of fracture [p = 0.047, OR 2.3 (95% CI 1.013-5.2)]. The AA genotype of the rs2228145 SNP (IL6R) was significantly different [p = 0.033, OR 1.94 (95% CI 1.01-3.75)], but when data were adjusted by age and body mass index, there were no differences (p = 0.9). CONCLUSION: Our results suggest that the IL6 rs1800796 SNP is a good marker for hip fracture risk in Mexican women.
