Transethnic insight into the genetics of glycaemic traits: fine-mapping results from the Population Architecture using Genomics and Epidemiology (PAGE) consortium
AssociationN=26,760Stephanie A. Bien et al.(2017)· Diabetologia

Transethnic fine-mapping study of glycaemic traits in 26,760 participants (Hispanic/Latino, African, Asian, and Native American) using the Metabochip. Replicated 31/39 fasting glucose and 14/17 fasting insulin loci from European GWAS. Identified two novel secondary signals at G6PC2-rs477224 and GCK-rs2908290, a population-specific signal at G6PC2-rs77719485 in African ancestry, and one novel locus at SLC17A2-rs75862513 for fasting insulin.

Fasting Glucose GWAS Candidate Region Analysis Across Ethnic Groups in the Multiethnic Study of Atherosclerosis (MESA)
AssociationN=5,550Rasmussen-Torvik LJ et al.(2012)· Genetic Epidemiology

This study examined genetic variants associated with fasting glucose from previously identified GWAS loci in four ethnic groups (Caucasian, African American, Hispanic, and Chinese descent) from the Multi-Ethnic Study of Atherosclerosis (MESA). The analysis focused on three gene regions (MTNR1B, GCK, and G6PC2) and found that rs10830963 in MTNR1B and rs4607517 in GCK demonstrated consistent magnitude of association with fasting glucose across ethnic groups (p = 1.29E-12 and p = 1.0E-7, respectively in meta-analysis), with effect sizes ranging from 1.22-1.66 mg/dl and -1.19 to -1.06 mg/dl respectively.

About GCK

This gene encodes a member of the hexokinase family of proteins. Hexokinases phosphorylate glucose to produce glucose-6-phosphate, the first step in most glucose metabolism pathways. In contrast to other forms of hexokinase, this enzyme is not inhibited by its product glucose-6-phosphate but remains active while glucose is abundant. The use of multiple promoters and alternative splicing of this gene result in distinct protein isoforms that exhibit tissue-specific expression in the pancreas and liver. In the pancreas, this enzyme plays a role in glucose-stimulated insulin secretion, while in the liver, this enzyme is important in glucose uptake and conversion to glycogen. Mutations in this gene that alter enzyme activity have been associated with multiple types of diabetes and hyperinsulinemic hypoglycemia. [provided by RefSeq, Aug 2017]
