IGF2BP2 [P = 1.3 × 10(-5); OR (95% CI): 1.66 (1.42-1.94)] and PPARγ [P = 0.005; OR (95% CI): 1.41 (1.10-1.80)] were associated with T2DM in the Lebanese, but not Tunisians, while KCNJ11 [P = 8.0 × 10(-4); OR (95% CI): 1.27 (1.09-1.47)] and SLC30A8 [P = 1.6 × 10(-5); OR (95% CI): 1.37 (1.15-1.62)] were associated with T2DM in the Tunisians, but not Lebanese, after adjusting for gender and body mass index.
In a case-control study, the frequency of the E23KKCNJ11 polymorphism of 43 diabetic patients with SH admitted to the emergency department was compared with a matched control group of 54 patients with T2D, but without a history of SH.
In addition to these polymorphisms, meta-analysis confirmed the association of type 2 diabetes susceptibility with KCNJ11rs5219, TCF7L2 rs7903146, and HHEX rs1111875.
In addition, we found evidence for association of SNPs in the genes PPARG, IGF2BP2, HHEX, TCF7L2, and FTO with type 2 diabetes in the same directions as previously described (p<0.05), but not for WFS1, CDKN2A/B, KCNJ11, or EXT2.
In conclusion, our results showed no evidence of a synergistic interaction between the KCNJ11Glu(23)Lys and PPARG Pro(12)Ala polymorphisms, but indicated that they may act in an additive manner to increase the risk of type 2 diabetes.
In contrast, no significant association was observed between the KCNJ11E23K gene polymorphism and T2D in the dominant genetic model (OR: 0.66, 95 % CI: 0.41-1.07, P = 0.09).The KCNJ11E23K gene polymorphism is associated with T2D risk in the Chinese Han population.
In this cross-sectional study, the aim was to explore the association of genetic variants in CYP2C9, ABCC8, KCNJ11 and TCF7L2 with good glycaemic control in Mexican type 2 diabetes (T2D) treated with glibenclamide.
IRS1, KCNJ11, PPARgamma2 and HNF-1alpha: do amino acid polymorphisms in these candidate genes support a shared aetiology between type 1 and type 2 diabetes?
Missense mutations in the pancreatic islet beta cell inwardly rectifying K+ channel gene (KIR6.2/BIR): a meta-analysis suggests a role in the polygenic basis of Type II diabetes mellitus in Caucasians.
Our calculations identified causal genetic variation within the ABCC8/KCNJ11 region for T2DM with an OR of approximately 1.15 in Caucasians and Asians.
Our investigation confirmed the association between the KCNJ11E23K variant and type 2 diabetes under a recessive model (KK vs EK+EE) in the Chinese Han population (odds ratio (OR)=1.25, 95% confidence interval (95% CI) 1.04-1.50, P=0.017).
Polymorphisms of the SUR1 (ABCC8) and Kir6.2 (KCNJ11) genes predict the conversion from impaired glucose tolerance to type 2 diabetes. The Finnish Diabetes Prevention Study.
Progress in gene identification for more common, multifactorial forms of type 2 diabetes has been slower, but there is now compelling evidence that common variants in the PPARG, KCNJ11 and CAPN10 genes influence T2D-susceptibility, and positional cloning efforts within replicated regions of linkage promise to deliver additional components of inherited susceptibility.
Rs5219 at KCNJ11 (E23K) was associated with peripheral nerve function in a Chinese population with type 2 diabetes mellitus, suggesting shared genetic factors for type 2 diabetes mellitus and diabetic polyneuropathy in this population.
