TL;DR
This study identifies potential drug targets for migraine by combining genetic and gene expression data, offering new avenues for precision medicine.
Contribution
A novel multi-omics pipeline integrating GWAS, eQTL, and PheWAS data to discover and prioritize migraine drug targets.
Findings
31 migraine-associated genes were identified in whole blood and 20 in brain tissue.
Eight genes showed interactions with known drug targets, enabling prediction of 41 potential repurposable drugs.
NR1D1, THRA, NCOR2, and CHD4 are prioritized for drug development based on druggability and safety profiles.
Abstract
Migraine is a complex neurological disorder that severely compromises quality of life. Current therapies remain inadequate, creating an urgent need for precision medicine approaches. To bridge this gap, we integrated genome-wide association studies (GWASs) and multi-tissue expression quantitative trait loci (eQTL) data. Using Mendelian randomization (SMR/HEIDI) to identify putatively causal genes, followed by colocalization analysis, protein–protein interaction networks, and gene enrichment, we prioritized druggable targets. Phenome-wide association studies (PheWASs) further assessed their potential safety profiles. We identified 31 migraine-associated genes in whole blood, 20 in brain tissue, and 9 genes shared by both whole blood and brain regions. Among 13 druggable genes identified from the DGIdb and supporting literature, 10 passed colocalization validation. Eight genes (TGFB3,…
