This meta-analysis examined the genetic correlations between inflammatory bowel disease (IBD) and eight psychiatric disorders using data from 486,601 individuals. Significant global genetic correlations were found, particularly with anxiety disorders (rho = 1.89 × 10 - 2, p = 8.02 × 10 - 11) and PTSD (rho = 2.19 × 10 - 2, p = 1.16 × 10 - 19). The study highlights shared genetic mechanisms that may underlie these comorbidities.
Key findings
- Global genetic correlation with anxiety disorder was rho = 1.89 × 10 - 2, p = 8.02 × 10 - 11.
- PTSD showed a significant correlation with IBD, rho = 2.19 × 10 - 2, p = 1.16 × 10 - 19.
- 274 significant regions were identified with Bonferroni correction in local genetic correlation analysis.
- 21 key pleiotropic genes were prioritized, including NOD2 and IL10.
Why it matters
Understanding the genetic overlap between IBD and psychiatric disorders can inform clinicians about the potential shared biological mechanisms, aiding in the management of patients with these comorbid conditions. This knowledge may lead to improved therapeutic strategies targeting both gastrointestinal and mental health.
