ABSTRACT
Single nucleotide polymorphisms (SNPs) in diabetes related peroxisome proliferator-activated receptor gamma (PPARG) gene were investigated with a case-control approach. To examine the genetic association of this gene with Alzheimer's disease (AD) risk, we used the TaqMan technique to genotype eight SNP sites for PPARG gene, in 538 Finnish AD cases and 672 controls and conducted a single allele and genotypic distribution comparison as well as estimated haplotype frequencies between cases and controls. No significant differences in AD risk were found in single SNP and haplotype analyses for PPARG gene between the study groups. We conclude that PPARG gene does not play a major role in the genetic predisposition to AD in the Finnish population.
