Genome-wide association study of major anxiety disorders in 122,341 European-ancestry cases identifies 58 loci and highlights GABAergic signaling

Abstract

The major anxiety disorders (ANX; including generalized anxiety disorder, panic disorder, and phobias) are highly prevalent, often onset early, persist throughout life, and cause substantial global disability. Although distinct in their clinical presentations, they likely represent differential expressions of a dysregulated threat-response system. Here we present a genome-wide association meta-analysis comprising 122,341 European ancestry ANX cases and 729,881 controls. We identified 58 independent genome-wide significant ANX risk variants and 66 genes with robust biological support. In an independent sample of 1,175,012 self-report ANX cases and 1,956,379 controls, 51 of the 58 associated variants were replicated. As predicted by twin studies, we found substantial genetic correlation between ANX and depression, neuroticism, and other internalizing phenotypes. Follow-up analyses demonstrated enrichment in all major brain regions and highlighted GABAergic signaling as one potential mechanism underlying ANX genetic risk. These results advance our understanding of the genetic architecture of ANX and prioritize genes for functional follow-up studies.

Figure 1:
Manhattan plot of the main ANX GWAS (122,341 ANX cases and 729,881 unaffected controls) showing 58 genome-wide significant loci. The x-axis shows the position in the genome (chromosome 1 to 22), the y-axis represents –log10 p-values for the association of variants with ANX from the meta-analysis using an inverse-variance weighted fixed effects model. The horizontal red line shows the threshold for genome-wide significance (P = 5×10−08). Dots represent each SNP that was tested in the GWAS with a green diamond indicating the lead SNP of a genome-wide significant locus and green dots below representing SNPs within the locus with high levels of LD with the lead SNP.

Figure 2:
List of 66 of the most highly-supported ANX genes that were implicated in at least three of the five SNP-(eQTL, HiC) or gene-based (MAGMA, M-SMR, P-SMR, T-SMR) tests. The left side indicates the position of the gene in the genome. Significance is indicated by a coloured dot. eQTL (blue dots) comparing results from brain-related eQTL studies for overlap in significance between our GWAS and the eQTL studies. HiC (green dots) used brain-related HiC information available through FUMA to functionally annotate our results. MAGMA (gray dots) tested genetic associations at the gene level for the combined effect of SNPs in or near protein coding genes. M/P/T-SMR (yellow, red, and pink dots, respectively) refers to transcriptome/proteome/methylome -wide analyses that assessed likely causal association between traits and gene/proteins/genomic regions by inferring the association between trait and gene expression/protein concentration/methylation, as predicted from genomic data.

The (rotated) Manhattan plot of the -log10 p-values of the ANX meta-analysis (left) and PheWAS alluvial plot of the pleiotropic variants (right). The colored ribbons depict variants that are pleiotropically associated with at least one other published GWAS finding and correspond with the color of the ribbon in the alluvial plot. The red diamonds in the Manhattan plot depict the most significant variant in the region corresponding with potentially ANX specific SNPs, i.e., a variant that reached the genome-wide significance threshold for ANX but not in any other published GWAS.

Bars represent 95% confidence intervals, red circles indicate significant associations after FDR correction for multiple testing. Black circles indicate associations that are not significant after FDR correction.
