The relation between FTO common variants and obesity has been replicated in diverse populations worldwide, including Mexican population (Andreasen et al., 2008; Dina et al., 2007; Do et al., 2008; Grant et al., 2008; Saldana‐Alvarez et al., 2016; Villalobos‐Comparan et al., 2008). This evidence concerns the gene FTO and obesity due to melanocortin 4 receptor deficiency.
