Peroxisome proliferator-activated receptor-gamma (PPARgamma) plays a role in adipocyte differentiation and insulin sensitization. We identified and characterized a new C/T substitution at position -689 (-689C>T) in the P2 promoter of PPARgamma in a putative GATA binding site. By electrophoretic mobility shift assay, both GATA2 and GATA3 proteins could bind weakly to the wild-type P2 -689 GATA binding site but not to the mutated site. Neither GATA2 nor GATA3 was able to regulate significantly the P2 promoter activity in a reporter-luciferase assay, whatever the allele at position -689 was, suggesting that the -689 putative GATA site was probably not a functional target for GATAs. However, the presence of the -689T allele rendered the P2 promoter less active at the basal state. We genotyped a population of 1155 men and women for the -689C>T polymorphism and looked for possible associations with anthropometric and lipid variables. The carriers of the -689T allele had elevated body weight and LDL-cholesterol concentrations compared with the homozygous for the common allele. Haplotype analyses including the -681C>G (P3 promoter), -689C>T (P2 promoter), and Pro12Ala (exon B) polymorphisms were performed. Carriers of the G-T-Ala haplotype (corresponding to the P3 -681C>G, P2 -689C>T and Pro12Ala polymorphisms in this order) had elevated LDL-cholesterol concentrations and body weight compared with C-C-Pro individuals. In conclusion, we identified a new polymorphism in the P2 promoter of PPARgamma. The P3 -681C>G, P2 -689C>T, and Pro12Ala polymorphisms and related haplotypes were associated with higher body weight and plasma LDL-cholesterol concentrations.
