PPARG and Obesity: Results obtained in the present study revealed four SNPs (rs1121980, rs1558902, rs9939609, rs9941349) in FTO (which are in LD, see Figure S4) with a significant effect on obesity among Roma; two of which (namely rs9939609 and rs9941349 in FTO) had a significant effect on BMI and five (rs1121980, rs1558902, rs9939609, and rs9941349 in FTO, and rs1801282 in PPARγ) on WC.
