life cycle [1,2], population [3-5], species [6-8], tissue [9,10], and cell [11,12]) and this variation drives phenotypic divergence among species and populations [13,14].A long-standing goal in population genetics and evolutionary biology has been to identify and characterize this . miRNA) or by spatial associations of the regulatory element and target gene. Keller, R.) 89110 (Springer International Publishing, 2019). Thank you for visiting nature.com. When present within a coding sequence and leading to an amino acid change (referred to as a non-synonymous SNP or mutation), they can modify the protein's activity. 1). Would you like email updates of new search results? However, our study also has several limitations. 78, 4763 (2021). Fetal and adult ASD-associated eQTLs were also associated with schizophrenia, unipolar depression, ADHD, bipolar disorder, anorexia nervosa and obsessivecompulsive disorder (Supplementary Fig. Breastfeed. Briefly, read counts were normalised using the TMM algorithm and genes were selected if they had counts of 0.1 TPM in 20% samples and 6 unnormalized reads in 20% samples.

Dynamics and stage-specificity of between-population gene expression Porokhovnik, L. Individual copy number of ribosomal genes as a factor of mental retardation and autism risk and severity. SF3B1 and THOC7 were also associated with ASD-eQTLs within the adult cortex. D'Esposito D, Guadagno A, Amoroso CG, Cascone P, Cencetti G, Michelozzi M, Guerrieri E, Ercolano MR. Planta. and transmitted securely. The size of each node depends on the protein expression levels (no missing values and minimum expression level >0 TPM) in the corresponding cortical tissue. To build ASD-specific fetal and adult CSPPIs, only interactions between ASD-associated genes we extracted from fetal and adult CSPPIs. Neurosci. How could SNPs contribute to gene regulation? contributed to discussions that aided results interpretation and commented on the manuscript. These findings indicate that there may be developmental stage-specific differences in the impact of the immune system on ASD risk and on-going severity. PubMed Nature 599, 628634 (2021). Article Sci. By contrast, in the fetal cortex changes in gene transcript levels occurred in immune pathways that were related to the processing of both endogenous and exogenous antigens. The GWAS Catalog is a publicly available database of all published GWAS studies76. Of 454 ASD-associated SNPs, 344 SNPs were represented in both fetal and adult cortex eQTL databases, and were run through the CoDeS3D pipeline (Fig. Removal of HLA genes from analyses of the adult cortex gene set identified a retained enrichment for immune-related processes (e.g. Genet. Cent. Each SNP represents a difference in a single DNA building block, called a "nucleotide." For example, an SNP may replace the nucleotide cytosine (C) with the nucleotide thymine (T) in a certain stretch of DNA. Most of these fetal ASD-associated eQTLs located within the Polycomb-repressed eQTLs were not identified as eQTLs in the adult cortex (Fig. Google Scholar. Coexpression networks implicate human midfetal deep cortical projection neurons in the pathogenesis of autism. 4). Enrichment analyses were performed using R package regioneR79 (permutation test: 1000). Genes regulated by Polycomb-repressed ASD-associated eQTLs in the fetal cortex. enhancer reporter assays); (b) confirm that the Polycomb complexes are responsible for the observed activity (e.g. To obtain If material is not included in the article's Creative Commons licence and your intended use is not permitted by statutory regulation or exceeds the permitted use, you will need to obtain permission directly from the copyright holder.

The remaining read pairs we refer to as contacts. 3). by chromatin immunoprecipitation); and (c) identify the Polycomb subunits that differentiate those sites that enhance or repress transcription within the developing cortex. Furthermore, we constructed fetal and adult cortex-specific proteinprotein interaction networks and identified that ASD-associated regulatory SNPs impact on immune pathways, fatty acid metabolism, ribosome biogenesis, aminoacyl-tRNA biosynthesis and spliceosome in the fetal cortex. 1, Supplementary Table 3). Systematic identification of trans eQTLs as putative drivers of known disease associations. Rev. PDE10A, PBX1, SF3B1, BAG6 and RERE) were LoF intolerant (Supplementary Table 6). The butyrophilin genes encode proteins that belong to the immunoglobulin superfamily and help modulate the immune system23. Here, we integrated ASD-associated GWAS SNPs with cortex-specific 3D genome structure and eQTL information to identify genes that are spatially regulated in fetal (1421 postconceptional weeks) and adult (2170years of age) cortical tissues. Genet. Numerous genome-wide eQTL analyses have been reported to comprehensively capture such a DNA-RNA (i.e . ISSN 1546-1718 (online) Wang, S.S.-H., Kloth, A. D. & Badura, A. Finally, protein identifiers (STRING)33 and transcript identifiers (GTEx and Walker et al. J. Mol. Genotypes (derived by Array Genotyping) for 219 fetal brain donors20 were downloaded from dbGaP (05/06/2020), processed and prepared in the GTEx format (Supplementary Fig. Therefore, with appropriate pre-natal genetic diagnosis of risk and patient stratification, it remains possible that targeted lipid supplementation could reduce the risk of ASD. NMB encodes the neuromedin B peptide that regulates physiological processes including cell growth, exocrine and endocrine secretion22; and (2) downregulates WDR73 in adult cortex. 2 How could SNPs contribute to gene regulation? https://doi.org/10.1038/s41588-022-01087-y (2022). Identification of functional single nucleotide polymorphisms in the branchpoint site. Google Scholar. A common two-phase adipogenesis process is described: early determination and terminal differentiation phases, involving an intricate integration of cytoarchitecture, transcription factors and co-regulators, and signaling pathways. As such, restriction fragments were used to identify regulatory interactions between SNPs and genes (Fig. J. Med. A Manhattan plot of association results from genome-wide association analysis.Y axis shows log 10 (P-value) of the association result for each SNP.Each SNP is indicated by a colored dot. Genetic control of expression and splicing in developing human brain informs disease mechanisms. Neurosci. Smith, R. M. & Sadee, W. Synaptic signaling and aberrant RNA splicing in autism spectrum disorders. We identified changes within multiple key component pathways of gene expression (i.e. Transl. Modules that were enriched with ASD-eQTL associated genes were identified in the fetal and adult cortical tissues. The majority of ASD-associated SNPs are located within the non-coding components of the genome. Grossniklaus, U. Nat. Notably, transcript levels for genes within this pathway were not significantly affected by ASD-eQTLs within adult cortex tissues (2170years of age). Provided by the Springer Nature SharedIt content-sharing initiative, Nature Genetics (Nat Genet) Using proteinprotein interaction (PPI) networks to explore interactions between proteins encoded by known disease-associated genes is a powerful approach to study the etiology of complex diseases, including psychiatric disorders17,18. It is estimated that the human genome contains more than 10 million different SNPs. Biol. In the meantime, to ensure continued support, we are displaying the site without styles & Jernigan, T. L.

All datasets and software used in the analysis are listed in Supplementary Table 1. Psychiatry https://doi.org/10.1038/s41380-020-0773-x (2020). There are several reasons for this apparent discrepancy. (f) The majority of the fetal ASD-associated eQTLs that are located within weakly repressed PolyComb (ReprPCWk) and repressed PolyComb (ReprPC) regions were not identified as being eQTLs within the adult cortex. Understanding the mechanisms underlying the effects of SNPs that . Frontiers | From GWAS to Function: Using Functional Genomics to Molecular genetics of human pigmentation diversity. Finally, beyond changes in the DNA sequence, changes in gene regulation - for example, by sRNAs and epigenetic factors - can play a key role in disease. Transcript levels for four genes: (a) increased (i.e. Google Scholar. We find that sex-het SNPs influence a large set of diseases and health-related . Cell Syst. Here, we integrated four distinct levels of biological information (GWAS, eQTL, spatial genome organization and proteinprotein interactions) to identify potential regulatory impacts of ASD-associated SNPs (p<5108) on biological pathways within fetal and adult cortical tissues. Estes, M. L. & McAllister, A. K. Maternal immune activation: Implications for neuropsychiatric disorders. FastQC reports were visually inspected and there were no samples that did not pass the quality check (no failures for Per base sequence quality, Per sequence quality scores, Per base N content and Sequence Length Distribution metrics). non-coding RNAs); (2) ASD is a spectrum . Frontiers | Exploring the Impact of Single-Nucleotide Polymorphisms on Rev. Rev. Brain Basics: Genes At Work In The Brain | National Institute of Desai, D. & Pethe, P. Polycomb repressive complex 1: Regulators of neurogenesis from embryonic to adult stage. The author declares no competing interests. In this study, we integrated four distinct levels of biological information (GWAS, eQTL, genome organization [Hi-C] and proteinprotein interactions [PPI] networks) to translate genetic variation associated with ASD to the biological pathways that are affectedthrough alterations to the transcription levels of their component proteins in fetal and adult cortical tissues. The Louvain clustering algorithm80 was further applied to identify ASD-specific clusters of functionally related proteins within the CSPPI networks. Child Psychol. ADS Cell 179, 750-771.e22 (2019). Notably, the significant difference (p=0.04531) in numbers of fetal cortical eQTLs, when compared to adult cortical eQTLs is consistent with a developmental origin for ASD risk. Regulatory roles and mechanisms of alternative RNA splicing in Nat. These mechanisms are not limited to impacts on gene regulation and can affect the splicing activity (so called sQTL SNPs35), or trans-acting factors (e.g.
