Association of peroxisome proliferator-activated receptor delta +294T/C with body mass index and interaction with peroxisome proliferator-activated receptor alpha L162V.
OBJECTIVE
To investigate the association of a polymorphism at position 294 (+294T/C) in the Peroxisome Proliferator-activated Receptor delta (PPARdelta) with body mass index (BMI) and the additional role of a gene-to-gene interaction between PPARdelta, PPARalpha and PPARgamma.


METHODS
An association between genetic variations in PPARdelta, PPARalpha and PPARgamma and indices of obesity and metabolism.


METHODS
A group of 462 moderately obese (mean BMI 28.9+/-7.7) and dyslipidemic, middle-aged (mean age 43.9+/-13.7), Caucasion men and women.


METHODS
The three most frequent single-nucleotide-polymorphisms (snp) in PPARdelta (+294T/C), PPARalpha (L162V) and PPARgamma (P12A) were genotyped and associated with clinical parameters.


RESULTS
The C allele in PPARdelta was significantly associated with a lower body mass index. Moreover an interaction between the polymorphisms in PPARalpha and PPARdelta on body weight could be demonstrated.


CONCLUSIONS
Our data provide further evidence for an involvement of PPARdelta in the regulation of BMI.
