Abstract
Background: A potential genetic link between inflammatory bowel disease (IBD) and educational attainment has been suggested. Understanding the underlying mechanisms of this genetic relationship is crucial for advancing the knowledge of their co-occurrence patterns.
Methods: Using genome-wide association study data for both IBD and educational attainment, a multiphase analytical approach was applied to examine their genetic correlation. The study involved three phases: first, linkage disequilibrium score regression and high-definition likelihood models were used to assess genome-wide genetic correlation; second, SUPERGNOVA was employed to analyze the genetic structure across specific chromosomal regions; and third, conditional/conjunctional false discovery rate (cond/conjFDR) methods were applied to measure genetic overlap and identify shared genetic loci between the two traits.
Results: The genome-wide analysis revealed significant genetic correlations between IBD, especially Crohn's disease, and educational attainment, while the association with ulcerative colitis was weaker. Regional analyses identified localized genetic correlation signals across several chromosomal regions between these traits. The application of the conjFDR framework confirmed the presence of overlapping genetic components, leading to the identification of key genetic variants contributing to disease susceptibility and progression.
Conclusion: This genetic study provides new theoretical insights into the association between IBD and educational attainment, contributing to a deeper understanding of the mechanisms underlying their co-occurrence.
期刊介绍：
The journal aims to publish papers which bring together clinical observations, psychological and behavioural abnormalities and genetic data. All papers are fully refereed.
Psychiatric Genetics is also a forum for reporting new approaches to genetic research in psychiatry and neurology utilizing novel techniques or methodologies. Psychiatric Genetics publishes original Research Reports dealing with inherited factors involved in psychiatric and neurological disorders. This encompasses gene localization and chromosome markers, changes in neuronal gene expression related to psychiatric disease, linkage genetics analyses, family, twin and adoption studies, and genetically based animal models of neuropsychiatric disease. The journal covers areas such as molecular neurobiology and molecular genetics relevant to mental illness.
Reviews of the literature and Commentaries in areas of current interest will be considered for publication. Reviews and Commentaries in areas outside psychiatric genetics, but of interest and importance to Psychiatric Genetics, will also be considered.
Psychiatric Genetics also publishes Book Reviews, Brief Reports and Conference Reports.
