Pandey et al. have shown higher circulatory levels of RBP4 and TTR in T2DM subjects, as well as a significant association between T2DM and RBP4 (OR = 1.11, 95% CI: 1.01–1.21) and TTR (OR = 1.34, 95% CI: 1.17–1.55) after adjusting for confounding factors [12]. This evidence concerns the gene TTR and type 2 diabetes mellitus.
