We examined whether zinc transporter 8 autoantibodies (ZnT8A; arginine ZnT8-RA, tryptophan ZnT8-WA, and glutamine ZnT8-QA variants) differed between immigrant and Swedish patients due to different polymorphisms of SLC30A8, HLA-DQ, or both. Newly diagnosed autoimmune (≥1 islet autoantibody) type 1 diabetic patients (n = 2,964, <18 years, 55% male) were ascertained in the Better Diabetes Diagnosi...

BACKGROUND Type 2 diabetes arises when insulin resistance-induced compensatory insulin secretion exhausts. Insulin resistance and/or beta-cell dysfunction result from the interaction of environmental factors (high-caloric diet and reduced physical activity) with a predisposing polygenic background. Very recently, genetic variations within four novel genetic loci (SLC30A8, HHEX, EXT2, and LOC387...

BACKGROUND Recent meta-analysis of genome-wide association studies in European descent samples identified novel loci influencing glucose and insulin related traits. In the current study, we aimed to evaluate the association between these loci and traits related to glucose metabolism in the Chinese. METHODS/PRINCIPAL FINDINGS We genotyped seventeen single nucleotide polymorphisms (SNPs) from f...

Type 2 Diabetes Mellitus (T2D) is the most common metabolic disease demonstrating itself by hyper- glycemia, due to impaired insulin secretion or action. Recently, Whole-Genome Association studies have revealed the role of several new genes responsible for T2D. One of the most studied genes is SLC30A8 (Zn-T8) which is exclusively expressed in pancreatic ?-cells and participates in insulin stora...

The Slc30a8 gene encodes the islet-specific zinc transporter ZnT-8, which provides zinc for insulin-hexamer formation. Polymorphic variants in amino acid residue 325 of human ZnT-8 are associated with altered susceptibility to Type 2 diabetes and ZnT-8 autoantibody epitope specificity changes in Type 1 diabetes. To assess the physiological importance of ZnT-8, mice carrying a Slc30a8 exon 3 del...

Leptin (LEP), a protein that plays a fundamental role in the metabolism of energy reserves, and the solute carrier family 30 A8 zinc transporter (SLC30A8) have been consistently associated with diabetes. Women with gestational diabetes are at moderate risk of developing diabetes type 1 and 2 after pregnancy, in addition to complications to the fetus. We investigated the association of the polym...

BACKGROUND Posttransplantation diabetes mellitus (PTDM) is a major metabolic complication in renal transplant recipients. Recent genome-wide association studies have identified several genes associated with type 2 diabetes. Here, we examined the association between PTDM and 17 single nucleotide polymorphisms (SNPs) located within 15 genes in a cohort of renal allograft recipients in Korea. MA...

Zinc transporter 8 genetic variant SLC30A8 has been associated with postpartum risk of type 2 diabetes among women with gestational diabetes mellitus (GDM). Gestational weight gain is one of the strongest risk factors for postpartum hyperglycemia. We assessed the interaction between type 2 diabetes-associated SLC30A8 rs13266634 and gestational weight gain on 1-5 years of postpartum glycemic cha...

BACKGROUND The association of type 2 diabetes mellitus (T2DM) with the KCNJ11, CDKAL1, SLC30A8, CDKN2B, and FTO genes in the Russian population has not been well studied. In this study, we analysed the population frequencies of polymorphic markers of these genes. METHODS The study included 862 patients with T2DM and 443 control subjects of Russian origin. All subjects were genotyped for 10 si...

The SLC30A8 gene codes for a pancreatic beta-cell-expressed zinc transporter, ZnT8. A polymorphism in the SLC30A8 gene is associated with susceptibility to type 2 diabetes, although the molecular mechanism through which this phenotype is manifest is incompletely understood. Such polymorphisms may exert their effect via impacting expression level of the gene product. We used an shRNA-mediated ap...
