PPARG gene promoter polymorphism is associated with non-traumatic hip fracture risk in the elderly Slovenian population: a pilot study.

摘要

OBJECTIVES: Peroxisome proliferator-activated receptor gamma (PPARgamma), an essential transcription factor for adipogenesis, has been implicated in pathogenesis of osteoporosis. The association of three single nucleotide polymorphisms in the PPARG gene with hip fracture risk, bone mineral density (BMD) and biochemical markers of bone turnover was investigated in the elderly. DESIGN AND METHODS: Six hundred sixty-seven elderly Slovenians were genotyped for SNPs rs12497191, rs1801282 and rs3856806. BMD and biochemical markers of bone turnover were measured. Haplotypes ACC, AGT and GCC, defined by rs12497191, rs1801282 and rs3856806 were assigned. Influence of genotype on fracture risk was assessed in 72 non-traumatic hip fracture cases and 272 controls. RESULTS: The rs12497191 G allele alone or in haplotype was associated with lower risk of non-traumatic hip fracture and higher serum receptor activator of nuclear factor kappaB ligand. CONCLUSIONS: The rs12497191 genotype could contribute to the incidence of non-traumatic hip fractures in the elderly.
