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 FN3KRP

A high concentration of glucose can result in non-enzymatic oxidation of proteins by reaction of glucose and lysine residues (glycation). Proteins modified in this way are less active or functional. This gene encodes an enzyme which catalyzes the phosphorylation of psicosamines and ribulosamines compared to the neighboring gene which encodes a highly similar enzyme, fructosamine-3-kinase, which has different substrate specificity. The activity of both enzymes may result in deglycation of proteins to restore their function. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Mar 2012]
