We did not find (Table 2) any statistically significant association between the FTO rs9939609 polymorphism and type 2 diabetes when analyzing the population as a whole (OR:1.07, 95%CI: 0.97-1.18; P=0.191 for carriers of the FTO obesity risk allele in comparisons with TT homozygotes in model 2). This evidence concerns the gene FTO and obesity due to melanocortin 4 receptor deficiency.
