We identified 80 eQTLs that are involved in 131 significant spatial eQTL-eGene interactions in fetal cortex; and 58 eQTLs that are associated with 67 significant spatial eQTL-eGene interactions in adult cortex (Fig. The Genotype-Tissue Expression (GTEx) Project was supported by the Common Fund of the Office of the Director of the National Institutes of Health, and by NCI, NHGRI, NHLBI, NIDA, NIMH, and NINDS. By contrast, the adult cortical gene set was largely related to immune pathways. Genes whose transcript levels are associated with a trans-acting ASD-associated eQTL. Within-family IDs were used as sample IDs in the output vcf file (recode vcf-iid bgz). Edges are only present if both interacting proteins are expressed in the cortical tissue. You'll get a detailed solution from a subject matter expert that helps you learn core concepts. Neurosci. Interacting fragments that overlapped annotated genes (GENCODE transcript model version 26) were subsequently identified (hereafter referred to as SNP-gene pairs). 45, 984994 (2013). Genet. These mechanisms are not limited to impacts on gene regulation and can affect the splicing activity (so called sQTL SNPs 35), or trans-acting factors (e.g. To obtain 44, 60466054 (2016). The regulatory effects can occur in trans (e.g. non-coding RNAs); (2) ASD is a spectrum . cortical plate and germinal zone neurons), or adult (i.e. Trials 18, 131 (2017). 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. Lettre, G. One step closer to linking GWAS SNPs with the right genes. Nat. Bootstrapping analysis (n=10,000 iterations) was performed to test if observed overlaps were non-random. 69, 101468 (2020). Overview of the analysis pipeline used in this study. Common genetic variants, acting additively, are a major source of risk for autism. The integration of spatial and functional data represents a significant difference from other approaches where functional assignments for phenotype-associated SNPs are typically made to the gene that is closest to the phenotype-associated SNP72.

Cold Spring Harb. There are studies connecting cortical dysfunctions and ASD using imaging14, cortical architecture15, or gene expression16. SNPs may change the encoded amino acids (nonsynonymous) or can be silent (synonymous) or simply occur in the noncoding regions. Genes that have been curated as being involved in ASD (AutDB31; http://autism.mindspec.org/autdb/Welcome.do, assessed on 16/11/2020). RNA-seq data) were mapped to Ensembl gene identifiers. The p value was calculated as the sum of these instances divided by the total number of iterations n. If the p<0.01 we assume that the observed relationship is non-random. Chiang, H.-L., Wu, J.-Y. 3). viral) lends some support the hypothesis that the risk of ASD may be greater among children whose mothers suffered from infectious or immune-related diseases during pregnancywhen the infant brain is developing60,61,62,63. Gentile, C. et al. SNPs represent an important class of genetic variant, defined as a single-base change in the DNA sequence. 2f). 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. An alternative explanation is that the existence of the shared eQTLs between the multimorbid conditions is due to ambiguity in the phenotyping that was used in the GWAS studies that characterised the phenotype associated-SNPs. & Vasan, R. S. Next-generation genome-wide association studies: Time to focus on phenotype?. As such, restriction fragments were used to identify regulatory interactions between SNPs and genes (Fig. 2c).

Fetal and adult ASD-associated eQTLs were also associated with schizophrenia, unipolar depression, ADHD, bipolar disorder, anorexia nervosa and obsessivecompulsive disorder (Supplementary Fig. Use the Previous and Next buttons to navigate the slides or the slide controller buttons at the end to navigate through each slide. The main strength of this study is the integration of independent data sets, across distinct biological levels, that include cortex-specific 3D genome structure, eQTL and PPI data with ASD-associated GWAS SNPs. American Psychiatric Association. The CSPPIs represents subnetworks of the STRING PPI network, in which a protein/node is only present if it is expressed in the cortical tissue (adult or fetal). 84% of the genes we identified were not present in AutDB. Internet Explorer). Transcript levels for 15 spatially regulated genes were altered by ASD-associated eQTLs in both the fetal and adult cortical tissues, 66 genes were specific to fetal cortex, and 29 eGenes were specific to the adult cortex. PubMed The proportion of ASD explained by SNPs has been estimated to be between 17 and 60%7,8, thus their contribution should not be neglected. One of main contributions of SNPs in clinical research is genome-wide association study (GWAS). Finally, our approach focuses on identifying changes in gene regulation that are associated with and may contribute to ASD. J. Immunol. Notably, the transcript levels for 6 genes in the fetal immune cluster (HCG27, TAP2, HLA-F, HLA-DMA, HLA-C and HLA-DMB) are associated with regulation by Polycomb-repressed ASD-eQTLs.

Overall, our findings highlight potential regulatory mechanisms and pathways important for the etiology of ASD in early brain development and adulthood. Next, the CoDeS3D algorithm identified the restriction fragments interacting with the SNP-containing restriction fragments. We define a well-powered list of 2,320 sex-het SNPs showing sex-heterogeneity across multiple traits. Weissbrod, O. et al. Physiol.

The fetal immune PPI cluster contains both MHC class I (i.e. Genet. Only SNP-phenotype associations with a p<5108 were included in the analysis. Transcriptome-wide fetal and adult cortex-specific PPIs (CSPPIs) were constructed by combining the STRING PPI network with cortex-specific expression data from GTEx v8 or fetal brain datasets (Fig. Pepper, K. L. et al. These simple changes can be of transition or transversion type and they occur throughout the genome at a frequency of about one in 1,000 bp. Louvain clustering analysis identified seven highly connected PPI modules within fetal cortex. SNPs in genes that regulate DNA mismatch repair, cell cycle regulation, metabolism and immunity are associated with genetic susceptibility to cancer [ 1 - 12 ]. 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. Perez, R.
