Association studies of the FTO gene with obesity or obesity-related traits have been reported in many populations across the world, confirming the strong association of FTO SNPs with BMI and/or obesity (Frayling et al., 2007; Scuteri et al., 2007; Hotta et al., 2008; Chang et al., 2008; Srivastava et al., 2016). The gene discussed is FTO; the disease is obesity disorder.
