FTO and breast cancer: In the current study, interestingly, the FTO rs7206790 and rs9939609 SNPs significantly correlated with BMI in BC patients; the frequency of the rs9939609 A allele and rs7206790 G allele in BC patients with BMI ≥ 30 kg/m2 was found to be increased (respectively, p=0.005 and p=0.031).
