title: Peroxisome proliferator-activated receptor-gamma gene polymorphisms are not associated with osteonecrosis of the femoral head in the Korean population.
abstract: Osteonecrosis of the femoral head (ONFH) is a multifactorial disease to which certain individuals are more at risk. Altered lipid metabolism is one of the major risk factors for osteonecrosis, especially corticosteroid therapy and alcoholism. Peroxisome Proliferator-Activated Receptor-gamma (PPARgamma) plays a crucial role in differentiation of mesenchymal cells to adipocytes, lipid homeostasis, and bone metabolism. To investigate the possible association between PPARgamma gene variants and susceptibility to ONFH, we genotyped three common polymorphisms (-796A > G, +34C > G[Pro12Ala], and +82466C > T[His477His]) in 448 ONFH patients and 336 control subjects. Genotypes, allele frequencies, and haplotypes of the polymorphisms in the complete set of patients as well as in subgroups by sex or etiology were not significantly different from those in the control group. This suggests that the examined polymorphisms and haplotypes of the PPARgamma gene are unlikely to be associated with susceptibility to ONFH.
