Single-nucleotide polymorphism - Wikipedia ADS This problem has been solved! SF3B1 and THOC7 were also associated with ASD-eQTLs within the adult cortex. Gene Ontology (GO) enrichment and pathways analyses for the eGenes within the ASD-specific CSPPI clusters were performed using the g:GOSt module of the g:Profiler tool81. cerebellum68) or non-brain regions implicated in ASD may identify additional candidate genes. PubMed Chromosome conformation elucidates regulatory relationships in developing human brain. Nat. 2c). J. Med. Single nucleotide polymorphism, or SNP. Article Lastly, tensorQTL (https://github.com/broadinstitute/tensorqtl) algorithm was used to perform cis- and trans-QTL mapping. Article Prevalence and outcomes of young people with concurrent autism spectrum disorder and first episode of psychosis. McCarthy, S. et al. non-coding RNAs); (2) ASD is a spectrum disorder not a single highly characterised phenotype; and (3) like all polygenic disorders, ASD is likely to be a whole of body disorder with important etiological contributions from discrete and distant organs within the body. The resulting vcf file was converted to plink format and information on sample sex included. Pedapati, E. V. et al. We have delimitated the minimal promoter to a region of less than 150 bp, with 63% of identity among 5 different species. volume11, Articlenumber:15867 (2021) Rev. Therefore, characterizing the functional impacts (i.e. Roles for these component gene expression processes in ASD are supported by existing studies (e.g. Schmitt, A. D. et al. Fetal ASD-associated eQTLs were located within quiescent/low transcribed (n=31), weak transcription (n=18), week repressed Polycomb (n=14) and repressed Polycomb (n=10) regions (Fig. There is no fundamental reason why the same regulatory elements must or must not impact on the same gene in different tissues, or at different stages of development. Genet. Genet. Thank you for visiting nature.com. By contrast, the adult cortical gene set was largely related to immune pathways. J. Maternal immune activation and abnormal brain development across CNS disorders. Article How do SNPs occur? Rev. eCollection 2022. In total, 663,956 variants passed QC filters. a, CWAS identify epigenomic features that are genetically associated with a trait. Science 353, 772777 (2016). Genet.

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). Our finding that a subset of the identified ASD-associated eQTLs were linked to psychiatric phenotypes highlights the existence of potential shared regulatory mechanisms contributing to the risk of developing these multimorbid conditions. The resulting CSPPI networks contained 1,784,342 PPIs between 17,156 unique proteins in the adult brain, and 1,690,571 PPIs between 16,519 unique proteins in the fetal brain. 51, 431444 (2019). Cells 8, 1151 (2019). Basu, S. N., Kollu, R. & Banerjee-Basu, S. AutDB: A gene reference resource for autism research. Nat. Roles for immune dysfunction in ASD etiology are increasingly being identified57,58,59. Article Nancy Y. Consistent with this, we identified that ASD-associated genetic variants impact transcript levels for genes involved in fatty acid metabolism in the developing fetal cortex (1421 postconceptional weeks). In Psychopathology in Adolescents and Adults with Autism Spectrum Disorders (ed. We contend that changing the transcription levels of these genes, alters biological pathways that modify an individuals predisposition to develop ASD. T.F. Notably, we found that ASD-eQTL associated changes in transcript levels occurred in adult cortex immune pathways that were associated with processing of exogenous antigen. Overall, our findings highlight potential regulatory mechanisms and pathways important for the etiology of ASD in early brain development and adulthood. This network illustrates potential evidence for gene regulation related to RA-associated SNPs, and may provide comprehensive information for subsequent functional analyses and experiments. Correspondence to 3). Notably, these regulatory elements are only associated with the expression (eQTL or expression quantitative trait locus) of the adjacent gene in ~40% of cases11. Sci. Cross-Disorder Group of the Psychiatric Genomics Consortium et al. Boyle, E. A., Li, Y. I. https://doi.org/10.1038/s41588-022-01093-0, DOI: https://doi.org/10.1038/s41588-022-01093-0. What are some common examples of known SNPs used in Brandler, W. M. et al. Similar approaches, in combination with existing and future clinical studies of ASD will contribute to individualized mechanistic understanding of ASD etiology in early brain development and adulthood. However, rs4481150 is only associated with increased transcript levels for ITIH4 in adult cortex. Psychiatry 10, 380 (2020). Google Scholar. Thousands of disease-associated SNPs (daSNPs) are located in intergenic regions (IGR), making it difficult to understand their association with disease phenotypes. Nat. Fifteen of these shared eQTLs control the same eGenes in fetal and adult cortex (e.g. 12, 230 (2018). Rev. 8600 Rockville Pike Brodie, A., Azaria, J. R. & Ofran, Y. Front. & Deptua, W. Butyrophilins: An important new element of resistance. However, it is likely that additional regions of the brain (e.g. Nucleic Acids Res. Tam, V. et al. Autism, early psychosis, and social anxiety disorder: Understanding the role of social cognition and its relationship to disability in young adults with disorders characterized by social impairments. Neurosci. Quality control metrics and gene-level expression data were calculated using RNA-seQC (v2.3.6) on the basis of GENCODE v26 gene annotation (gencode.v26.GRCh38.genes.gtf, gs://gtex-resources). 4), contained genes (i.e. Cell 167, 1481-1494.e18 (2016). Fourthly, the human brain takes over two decades to build via precisely regulated cell type-specific molecular processes governed by both genetic blueprint and environmental factors. Juicer provides a one-click system for analyzing loop-resolution Hi-C experiments. HLA-C and HLA-F; associated with endogenous antigen processing) and MHC class II (i.e. 16, 469486 (2015). Python (version 3.6.9), R (version 4.0.2) and RStudio (version 1.2.5033) were used for data analysis and visualisation. Golovina, E., Fadason, T., Lints, T.J. et al. Article All genomic positions and SNP annotations were obtained for human genome reference build hg38 (GRCh38) release 75. PubMed Nott, A. et al. Of the 80 fetal and 58 adult eQTLs, 30 were observed in both fetal and adult cortical tissues (Fig. Front. Collectively, these observations are consistent with changes in the regulation of subsets of stable and remodelled spatial eQTLs, over the course of brain development, being associated with a predisposition to ASD. These differences can underlie susceptibility to common diseases, human traits, and differential responses to drugs. Enrichment analyses were performed using R package regioneR79 (permutation test: 1000). 46, 881885 (2014). 45, D896D901 (2017). https://doi.org/10.1038/s41598-021-95447-z, DOI: https://doi.org/10.1038/s41598-021-95447-z.

Gene expression is the outcome of numerous processes including transcription, co-transcriptional splicing, mRNA export, and translation. Bethesda, MD 20894, Web Policies For SNPs analysis, we resampled SNPs from the list of all GWAS SNPs with gwas p<5108. Schizophr. Pepper, K. L. et al. 69, 101468 (2020). Nat. GWAS studies have identified genetic variants associated with ASD, but the functional impacts of these variants remain unknown. and JavaScript. Paternally inherited cis-regulatory structural variants are associated with autism. The fetal immune PPI cluster contains both MHC class I (i.e. Rev. Similar changes occur in adult cortex where transcript levels for 15 genes are upregulated in association with a change to the minor allele at the eQTL SNP (Fig. N. Engl. Front. Google Scholar. Ernst, J. Estes, M. L. & McAllister, A. K. Maternal immune activation: Implications for neuropsychiatric disorders. The significance level was determined using the BH algorithm (FDR<0.05). ASD-eQTLs were also associated with increases in HCG27 (TPM=3) and NDUFA6 (TPM=116.31) transcript levels within fetal cortex. Hudson, C. C., Hall, L. & Harkness, K. L.

Collectively, our results provide insight into potential cortex-specific regulatory mechanisms and pathways through which ASD-associated SNPs can contribute to the development and maintenance of ASD. TYW5, FTCDNL1, and RTN1) whose transcript levels decrease with the ASD-eQTL and NDRG4, whose transcript levels increase or decrease dependent upon the ASD-eQTL. PubMed They can act as biological markers, helping scientists locate genes that are associated with disease. Won, H. et al. Chapter There are several reasons for this apparent discrepancy. We contend that our approach represents a valuable strategy to identify potential ASD candidate genes. Collectively these results could indicate the existence of a window of tolerable variation within gene expressionoutside of which there is risk of developing ASD through changes in global gene expression. Moreover, Trlungeanu et al. BCFtools (v1.10.2) was used to exclude genetic variants on chromosome 0 (omitted due to mapping to multiple locations) and chromosome 25 (XY pseudoautosomal region), to rename chromosomes 23 (X), 24 (Y) and 26 (MT), to fix REF allele, to check samples sex and to normalize the output vcf file to the GRCh37 reference genome (human_g1k_v37.fasta.gz, downloaded from ftp://ftp.1000genomes.ebi.ac.uk/vol1/ftp/technical/reference/, 01/07/2020). g:Profiler: A web server for functional enrichment analysis and conversions of gene lists (2019 update). Analyzing the Effects of Genetic Variation in Noncoding - ScienceDirect Science 337, 11901195 (2012). However, studies have shown that Polycomb repressive complexes (PRC) can have a dual role in gene regulation during development45,46. Neurosci. Frontiers | Exploring the Impact of Single-Nucleotide Polymorphisms on 3). Cell Rep. 17, 20422059 (2016). sharing sensitive information, make sure youre on a federal 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. & Jernigan, T. L. The basics of brain development. Increasing the number and sample sizes of the ASD GWAS studies will identify additional genetic variants which may help explain some of this missing heritability67. official website and that any information you provide is encrypted Genes whose transcript levels are associated with a trans-acting ASD-associated eQTL. Secondly, the finding that these ASD-eQTLs are associated with both increases and decreases in transcript levels is consistent with the up- and downregulation of the target genes. 4, Supplementary Table 9).
