This observation aligns with several other studies in children and adolescents that observed an association between SNPs on FTO and adiposity traits, such as BMI (den Hoed et al., 2010; Felix et al., 2016), BMI z-score (Namjou et al., 2013), and obesity (Zhao et al., 2011; Bradfield et al., 2012; da Silva et al., 2018). This evidence concerns the gene FTO and obesity due to melanocortin 4 receptor deficiency.
