In this study, we examined the association between three FTO variants (rs8050136, rs9939609, and rs9930506) and obesity and related traits in a population-based study of 3,210 unrelated Chinese Han subjects from Shanghai and Beijing.
HTR2C, LEP, FTO and TBC1D1 represented the top genes for weight gain during treatment with a SGAP and/or MS. A genome-wide signal (FTO rs9930506) associated previously with obesity was associated with psychotropic-induced weight gain.
The risk alleles for obesity ("A" allele for the rs9939609 FTO variant and "G" allele for the rs9930506 FTO variant) were associated with low weight at birth.
This association, which was detected for the first time in this population, suggests that FTOrs9930506 is a predisposition marker to obesity in the Greek adults, but the results should be taken cautiously due to the limitation of the relatively small sample size of the subjects.
