Our research has confirmed an association between the pro12ala allele and reduced incidence of obesity in pre-pubertal children and there are strong associations between genetic variation at the PPARG locus and percentage body fat.
Concurrently, genotyping of the Pro12Ala polymorphism showed that obese subjects possess a significantly higher frequency of the Pro/Pro genotype than nonobese controls (90.5 vs 79.5%; P = 0.03), suggesting that this genotype is involved in an increased risk of obesity in the Tunisian population.
The Pro12Ala polymorphism in the peroxisome proliferator-activated receptor gamma (PPARG) gene in relation to obesity and metabolic phenotypes in a Taiwanese population.
Beta3AR Trp64Arg and PPARgamma2 Pro12Ala polymorphisms might be associated with insulin resistance and obesity, and there might be slight synergistic effects between this two gene loci, and further studies are necessary to confirm this finding.
The Pro12Ala polymorphism in exon B of peroxisome proliferator-activated receptor gamma 2 (PPAR gamma 2) gene has been related to obesity, insulin resistance, and risk of type 2 diabetes.
In conclusion, the higher frequency of the C-->T substitution in exon 6 of the PPAR-gamma gene in PCOS women suggests that it plays a role in the complex pathogenetic mechanism of obesity in PCOS, whereas the Pro(12)Ala polymorphism does not seem to affect BMI in PCOS women.
The present study provides evidence that the Pro12Ala polymorphism of the PPARgamma-2 gene is associated with obesity in non-diabetic men from Tunisian origin.
These results suggest that the Pro12Ala mutation in PPARgamma is not associated with either diabetes or obesity and may not be an important determinant of obesity or diabetes in Korean subjects.
Many studies have focused on the physiological parameters and genetic predisposition of subjects presenting both obesity and insulin resistance (IR) and it has been suggested that the peroxisome proliferator-activated receptor gamma 2 (PPARgamma2) Pro12Ala variant may contribute to the observed variability in insulin sensitivity.
A functional single nucleotide polymorphism (SNP) that predicts a proline to alanine substitution (Pro12Ala) within the coding region of this gene has previously been associated with obesity and type 2 diabetes in several populations.
The single nucleotide polymorphisms (SNPs) of the above genes, such as GNB3-C825T, ADRB3-Trp64Arg, UCP2-3'UTR 45 bp del/ins, and PPARγ-Pro12Ala, are associated with obesity and body mass index.
Studies on the association of the Pro12Ala and C1431T polymorphisms of PPAR? with diabetes and obesity have revealed extensive population-dependent variations.
The association of the C1431T silent mutation and the Pro12Ala missense transversion within the PPARgamma gene with the development of T2DM or obesity has often yielded contradictory results.
Here, we investigated the expression of APM1 in adipose tissue and studied the relationship between variation in APM1 expression, the APM1 G276T polymorphism, the common PPARG Pro12Ala polymorphism and clinical features of 36 morbidly obese (body mass index (BMI) 41.5 +/- 4.9 kg/m2) nondiabetic subjects.
We have determined the Pro12Ala variant frequency in 370 nondiabetic Mexican Mestizo subjects and in five Mexican Amerindian groups and have investigated its possible association with lipid metabolism, insulin serum levels, and obesity in three of these populations.
