Using genetics to aid detection of adverse drug effects: a Mendelian randomisation analysis of genetically proxied GLP-1RA in 1,020,464 participants across three population-based cohorts
This Mendelian randomisation study of over one million participants demonstrates that genetically proxied GLP-1 receptor agonism not only replicates the drug's beneficial effects on glucose, BMI, and type 2 diabetes risk but also confirms causal links to increased risks of pancreatitis (particularly in older adults and drinkers) and sarcopenia, highlighting the potential of genetic approaches to enhance drug safety surveillance.
