Randomized trial explores genetic links between inflammatory bowel disease and psychiatric disorders, suggesting shared mechanisms.

Key Points

To investigate the genetic correlations between inflammatory bowel disease and eight psychiatric disorders, highlighting shared pathogenic mechanisms.
Analyzed GWAS summary statistics from 486,601 individuals for IBD and multiple datasets for psychiatric disorders.
Conducted global and local genetic correlation analyses to assess genetic overlap and region-specific associations.
Utilized summary data-based Mendelian randomization and multi-trait analysis of GWAS to identify pleiotropic variants.
Identified 274 significant regions with local genetic correlations, including loci 464 and 960.
Detected 1,125 independent pleiotropic loci, with 21 key pleiotropic genes prioritized.
Highlighted immune-related and neurobiological pathways relevant to the gut-brain axis.
