Abstract
OBJECTIVE— Using the genome-wide association approach, we recently identified the glucokinase regulatory protein gene ( GCKR , rs780094) region as a novel quantitative trait locus for plasma triglyceride concentration in Europeans. Here, we sought
to study the association of GCKR variants with metabolic phenotypes, including measures of glucose homeostasis, to evaluate the GCKR locus in samples of non-European ancestry and to fine- map across the associated genomic interval.
RESEARCH DESIGN AND METHODS— We performed association studies in 12 independent cohorts comprising >45,000 individuals representing several ancestral groups
(whites from Northern and Southern Europe, whites from the U.S., African Americans from the U.S., Hispanics of Caribbean origin,
and Chinese, Malays, and Asian Indians from Singapore). We conducted genetic fine-mapping across the ∼417-kb region of linkage
disequilibrium spanning GCKR and 16 other genes on chromosome 2p23 by imputing untyped HapMap single nucleotide polymorphisms (SNPs) and genotyping 104
SNPs across the associated genomic interval.
RESULTS— We provide comprehensive evidence that GCKR rs780094 is associated with opposite effects on fasting plasma triglyceride ( P meta = 3 × 10 −56 ) and glucose ( P meta = 1 × 10 −13 ) concentrations. In addition, we confirmed recent reports that the same SNP is associated with C-reactive protein (CRP) level
( P = 5 × 10 −5 ). Both fine-mapping approaches revealed a common missense GCKR variant (rs1260326, Pro446Leu, 34% frequency, r 2 = 0.93 with rs780094) as the strongest association signal in the region.
CONCLUSIONS— These findings point to a molecular mechanism in humans by which higher triglycerides and CRP can be coupled with lower plasma
glucose concentrations and position GCKR in central pathways regulating both hepatic triglyceride and glucose metabolism.
