Abstract
OBJECTIVE:
To investigate whether genetic variation in the cyclic GMP-dependent protein kinase gene (PRKG1) is associated with obesity.
METHODS:
The study included 143 individuals from New York City area, NY, USA. The subjects were sampled on the basis of body mass index (BMI): obese (BMI ranging from 33.8 to 89.5 kg/m2), and nonobese (BMI ranging from 16.0 to 29.4 kg/m2). The association between C2276T polymorphism in PRKG1 gene and obesity was tested using linear regression analysis.
RESULTS:
BMI levels were predicted by linear regression models adjusted for demographic factors. An analysis was performed twice: in individuals of all ethnical backgrounds and in European-Americans only. In both cases, genotype did not have a significant effect.
CONCLUSION:
We found no evidence that the C2276T polymorphism in the PKRG1 gene is associated with obesity.
