The study also revealed a 3.35% hypomethylation at a CpG site, located within the intron 1 and 11 bp upstream of the obesity and T2D-associated rs1121980 of the FTO gene, in T2 diabetics (n = 198) relative to non-diabetics (n = 233). The gene discussed is FTO; the disease is obesity due to melanocortin 4 receptor deficiency.
