However, there are respective limitations in the pharmacological strategies for the current treatment of GDM. Glucokinase regulatory protein (GCKR) has been associated with GDM in observational studies and animal experiments and thus represents a potential drug target of interest for investigation.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>We applied two\u2010sample Mendelian randomization (MR) and colocalization analysis using summary\u2010level data from genome\u2010wide association studies of GCKR and GDM. Two\u2010step MR was used to explore the mediating effects of several metabolic factors on the association. We also applied MR to explore the associations of GCKR levels with GDM\u2010related outcomes. Finally, we performed a phenome\u2010wide association study (PheWAS) to query the potential effects of altered GCKR levels across multiple health categories.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>We found a significant association between elevated GCKR levels and GDM (OR\u2009=\u20093.466, 95% CI\u2009=\u20092.401\u20135.002, <jats:italic>p<\/jats:italic>\u2009=\u20093.16\u2009\u00d7\u200910<jats:sup>\u221211<\/jats:sup>), also supported by the colocalization analysis ([<jats:italic>P<\/jats:italic><jats:sub>coloc<\/jats:sub>]\u2009=\u20090.997). The estimates were replicated in an independent study (OR\u2009=\u20092.640, 95% CI\u2009=\u20091.983\u20133.513, <jats:italic>p<\/jats:italic>\u2009=\u20092.84\u2009\u00d7\u200910<jats:sup>\u221211<\/jats:sup>, <jats:italic>P<\/jats:italic><jats:sub>coloc<\/jats:sub>\u2009=\u20090.983). Elevated GCKR levels were also associated with higher risk of type 2 diabetes (OR\u2009=\u20092.183, 95% CI\u2009=\u20091.846\u20132.581, <jats:italic>p<\/jats:italic>\u2009=\u20096.53\u2009\u00d7\u200910<jats:sup>\u221220<\/jats:sup>). Two\u2010step MR suggested that fasting glucose, fasting insulin, and triglycerides partly mediated the causal relationship.
