An atlas of genetic variation for linking pathogen-induced cellular traits to human disease

ABSTRACT: Genome-wide association studies (GWAS) have identified thousands of genetic variants associated with disease. To facilitate moving from associations to disease mechanisms, we leveraged the role of pathogens in shaping human evolution with the Hi-HOST Phenome Project (H2P2): a catalog of cellular GWAS comprised of 79 phenotypes in response to 8 pathogens in 528 lymphoblastoid cell lines. Seventeen loci surpass genome-wide significance (p<5x10-8) for phenotypes ranging from pathogen replication to cytokine production. Combining H2P2 with clinical association data on 83,717 patients from the eMERGE Network and experimental validation revealed evidence for mechanisms and connections with diseases. We identified a SNP near CXCL10 as a cis-cytokine-QTL and risk factor for inflammatory bowel disease. A SNP in ZBTB20 demonstrated pleiotropy, likely through suppression of multiple target genes, and was associated with viral hepatitis. Data are in an H2P2 web portal to facilitate interpreting human genome variation through the lens of cell biology.

A common cis-regulatory variant impacts normal-range and disease-associated human facial shape through regulation of PDKCC during chondrogenesis [HiChIP]

Project description:Genome-wide association studies (GWAS) identified thousands of genetic variants linked to phenotypic traits and disease risk. However, mechanistic understanding of how GWAS variants influence complex morphological traits and can, in certain cases, simultaneously confer normal-range phenotypic variation and disease predisposition, is still largely lacking. Here, we focus on rs6740960, a single nucleotide polymorphism (SNP) at the 2p21 locus, which in GWAS studies has been associated both with normal-range variation in jaw shape and with an increased risk of non-syndromic orofacial clefting. Using in vitro derived embryonic cell types relevant for human facial morphogenesis, we show that this SNP resides in an enhancer that regulates chondrocytic expression of PKDCC - a gene encoding a tyrosine kinase involved in chondrogenesis and skeletal development. In agreement, rs6740960 SNP is sufficient to confer a large difference in acetylation of its cognate enhancer preferentially in chondrocytes. By deploying dense landmark morphometric analysis of skull elements in mice, we show that changes in Pkdcc dosage are associated with quantitative changes in maxilla, mandible, and palatine bone shape that are concordant with the facial phenotypes and disease predisposition seen in humans. We further demonstrate that the frequency of the rs6740960 variant strongly deviated among different human populations, and that the activity of its cognate enhancer diverged in hominids. Our study provides a mechanistic explanation of how a common SNP can mediate normal-range and disease-associated morphological variation, with implications for the evolution of human facial features.

Methylome profiling of human glioblastoma using Illumina 450K microarrays for the GlioTeX panel

Project description:Genome-wide methylation profiles were generated as part of a multi-omics characterization (SNP array, WES, RNA-seq, cDNA microarray) of a panel of gliomasphere cell lines and matched parental tumors. See https://www.ncbi.nlm.nih.gov/pubmed/27571888 about the GlioTeX panel. Methylation profiling data in this record come from tumour samples. SNP array (ArrayExpress E-MTAB-4804), cDNA microarray (ArrayExpress E-MTAB-4803), WES and RNAseq (European Genome-Phenome Archive EGAS00001001871) have been published before. In addition, for the current project we compare 450K methylation data to nanopore sequencing based methylation profiles. These sequencing data will be accessible via European Genome-Phenome Archive (EGAS00001002213).

Transcript profile comparison of Zbtb20-sufficient and Zbtb20-deficient polyclonal bone marrow plasma cells

Project description:ZBTB20 is an adjuvant-specific factor for long-term antibody responses. This factor is critical for maintaining long-lived plasma cells in alum-adjuvanted antibody responses but is dispensable for TLR ligand-adjuvanted responses. To identify the functions of ZBTB20 in long-lived plasma cells, we performed microarray analysis on Zbtb20-sufficient and Zbtb20-deficient polyclonal bone marrow plasma cells under the assumption that ZBTB20 regulates relevant targets in all long-lived plasma cells, irrespective of their mode of formation. Chimeras were generated using Zbtb20-sufficient (WT) or Zbtb20-deficient (TRAP) E14.5 fetal livers. 3-4 months after reconstitution, donor bone marrow B220low/-CD138+ cells (4 replicates per genotype) were purified via FACS for microarray. In total, 8 samples, 4 for each genotype, were included in this study.

Affymetrix 6.0 SNP arrays interrogated to detect allele-specific DNA modification in the brain

Project description:It has long been hypothesized that knowledge of allele-specific modification (ASM; "modification" is used to denote various types of epigenetic cytosine marks, not only methylation) can supplement and inform GWAS of complex diseases and traits. To explore the relationship between GWAS subthreshold SNPs and ASM, we identified brain ASM-SNPs from Caucasian control individuals (n=76) and Caucasian patients affected by schizophrenia (n=65) or bipolar (n=67) using the Affymetrix SNP 6.0 microarray, one of the most common GWAS platforms which has also been thoroughlyt validated for ASM mapping. The brain samples (N=230, all ethnicities) were interrogated twice on Affymetrix SNP 6.0 microarrays. First, regular SNP genotyping was performed following the manufacturer's protocol. Second, we investigated allelic differences in DNA methylation by enriching the unmodified DNA fraction using DNA methylation-sensitive restriction enzymes.

Expression data from P2 mouse hippocampus

Project description:Zinc finger protein ZBTB20 plays a critical role in mouse hippocampal development by orchestrating gene expression profile of hippocampal neurons. We used microarrays to investigate the target gene of ZBTB20 in mouse hippocampal development. Mouse hippocampi were harvested at postnatal day 2 for RNA extraction and hybridization on Affymetrix microarrays. We sought to identify the target genes of transcription factor ZBTB20 in hippocampal development. To that end, we isolated the hippocampi from ZBTB20 knockout and their littermate control mice.

Expression data from adult mouse islets

Project description:Zinc finger protein ZBTB20 plays a critical role in regulating insulin expression from islet beta-cells by orchestrating their gene expression profile. We used microarrays to investigate the target gene of ZBTB20 in mouse pancreatic beta-cells. Adult mouse islets were harvested for RNA extraction and hybridization on Affymetrix microarrays. We sought to identify the target genes of transcription factor ZBTB20 in beta-cells. To that end, we isolated the islets from adult beta cell-specific ZBTB20 knockout and their littermate control mice.
