This has prompted several large-scale efforts ( 10 – 16) to generate comprehensive functional genomic compendia connecting population-level allelic variation with gene expression profiles in the human brain. As risk loci are enriched in known regulatory regions of the human genome ( 4 – 6), one major approach to address this challenge has been to connect risk variants with tissue-specific reference panels of expression quantitative trait loci (eQTLs), through statistical colocalization, transcriptome-wide association (TWAS), and related approaches ( 7 – 9). Consequently, the critical defining obstacle of the post-GWAS era is to pinpoint the specific, locus-level molecular impact of GWAS variants at scale ( 3). However, as most associated GWAS variants reside within non-coding regions of the human genome, often in large linkage disequilibrium (LD) blocks, the true underlying causal variant(s) and their target gene(s) remain largely unknown. Thousands of genetic risk loci have now been robustly associated with neurodevelopmental and psychiatric disorders by large-scale GWAS ( 1, 2). Together, this work provides a comprehensive view of genetic regulation across human brain development as well as the stage-and cell type-informed mechanistic underpinnings of neuropsychiatric disorders. Finally, we build a comprehensive set of developmentally regulated gene and isoform co-expression networks capturing unique genetic enrichments across disorders. Via colocalization and TWAS, we prioritize biological mechanisms for ~60% of GWAS loci across five neuropsychiatric disorders, nearly two-fold that observed in the adult brain. Isoform-level regulation, particularly in the second trimester, mediates the greatest proportion of heritability across multiple psychiatric GWAS, compared with eQTLs. ![]() We observe a striking drop in gene expression and splicing heritability as the human brain develops. We identify 15,752 genes harboring a significant xQTL and map 3,739 eQTLs to a specific cellular context. Here, we uniformly process and systematically characterize gene, isoform, and splicing quantitative trait loci (xQTLs) in 672 fetal brain samples from unique subjects across multiple ancestral populations. However, prioritizing the specific risk genes and candidate molecular mechanisms underlying these genetic enrichments has been hindered by the lack of a single unified large-scale gene regulatory atlas of human brain development.
