Many researchers clearly indicate the role of peroxisome proliferator-activated receptor gamma 2 (PPARγ2) gene (polymorphisms: Pro12- ?>Alars1801282 and C1431Trs3856806) and beta-3 adrenergic receptor (ADRβ3) gene (polymorphism: Trp64Argrs4994) among the candidate genes for hyperglycaemia and development of type 2 diabetes mellitus (Altshuler et al. 2000; Bell and Polonsky 2001; Grygiel-Górniak 2014). The gene discussed is PPARG; the disease is Hyperglycemia.
