GLIS3 and type 2 diabetes mellitus: Since GLIS3-rs7034200 is more likely a marker of the causal variant and the risk A-allele frequency of GLIS3-rs7034200 is similar between Chinese Hans and white Europeans, the disparity in the magnitude of the associations with glucose and type 2 diabetes might be due to ethnic-specific LD pattern between GLIS3-rs7034200 and the as-yet unidentified causal variant.
