Association of glycosylated hemoglobin with the gene encoding CDKAL1 in the Korean Association Resource (KARE) study
Meta-analysisN=159,940Jihye Ryu et al.(2012)· Human Mutation

Transethnic genome-wide meta-analysis in 159,940 individuals identified 60 common genetic variants associated with HbA1c levels. Variants were classified as glycemic (19), erythrocytic (22), or unclassified (19) based on their biological mechanisms. Glycemic variants were associated with higher type 2 diabetes risk (OR=1.05 per allele, p=3×10⁻²⁹), while erythrocytic variants were not. The X-linked G6PD G202A variant showed a large effect in African Americans (0.81% HbA1c reduction per allele) but minimal effects in other ancestries, potentially causing 2% of African American T2D cases to remain undiagnosed when using HbA1c screening.

About TCF7L2

This gene encodes a high mobility group (HMG) box-containing transcription factor that plays a key role in the Wnt signaling pathway. The protein has been implicated in blood glucose homeostasis. Genetic variants of this gene are associated with increased risk of type 2 diabetes. Several transcript variants encoding multiple different isoforms have been found for this gene.[provided by RefSeq, Oct 2010]
