Excerpt
Obesity is a major predictor of future risk of type 2 diabetes [
1] and the escalating prevalence of type 2 diabetes worldwide is mainly attributable to the continued rise in obesity observed over the last decades [
2]. Identification of the complex interactions and shared molecular pathways linking obesity and type 2 diabetes is an area of intense research [
3]. Human molecular genetics in particular has led to the identification of numerous molecular determinants of obesity and type 2 diabetes and to the global conclusion that the genes involved in genetic predisposition towards type 2 diabetes influence pancreatic beta cell function/mass and, to a lesser extent, insulin action, whereas obesity predisposing genes modulate hypothalamic sensing and control of energy balance [
4,
5]. To date, few loci have been convincingly associated with both obesity- and type 2 diabetes-related traits, and
FTO, in addition to
IRS1 [
6,
7],
ENPP1 [
8‐
10] or
GIPR [
11,
12], may be one of the molecular determinants linking obesity and type 2 diabetes. …
