The T allele of rs1260326 has been associated with type 2 diabetes and hypertriglyceridemia. A fine mapping approach indicates that this SNP, rs1260326, shows the strongest association signal with metabolic phenotypes in the region that also harbors the tightly linked (r(2)=0.93) SNP rs780094, which has been previously associated with triglyceride and glucose concentrations. This SNP, rs1260326, encodes a common missense glucokinase regulatory protein gene GCKR variant. gout association, based on Loci related to metabolic-syndrome pathways including LEPR,HNF1A, IL6R, and GCKR associate with plasma C-reactive protein: the Women's Genome Health Study.
