Overview
- A meta-analysis of genetic and self‑reported symptom data from 693,869 people found 80 variants in 74 genomic loci associated with anxiety, with 39 of those loci newly reported.
- The study estimates SNP‑based heritability at roughly 6% and reports that current polygenic scores explain about 1.2%–2.9% of symptom variance across tested populations.
- Several implicated genes, including PCLO and SORCS3, are especially active in brain tissue and relate to neuronal communication, suggesting biological pathways for anxiety risk.
- Researchers detected broad genetic correlations between anxiety and conditions such as depression, irritable bowel syndrome, chronic pain, coronary artery disease, endometriosis, and migraine, but they say these links do not prove causation.
- Authors and funders say the findings expand discovery but have limited near‑term clinical use, and they call for larger, ancestry‑diverse studies and follow‑up work to test causal mechanisms and real‑world utility.
