    Description: Sequence polymorphisms in a 58-kilobase (kb) interval on chromosome 9p21 confer a markedly increased risk of coronary artery disease (CAD), the leading cause of death worldwide. The variants have a substantial effect on the epidemiology of CAD and other life-threatening vascular conditions because nearly one-quarter of Caucasians are homozygous for risk alleles. However, the risk interval is devoid of protein-coding genes and the mechanism linking the region to CAD risk has remained enigmatic. Here we show that deletion of the orthologous 70-kb non-coding interval on mouse chromosome 4 affects cardiac expression of neighbouring genes, as well as proliferation properties of vascular cells. Chr4(Delta70kb/Delta70kb) mice are viable, but show increased mortality both during development and as adults. Cardiac expression of two genes near the non-coding interval, Cdkn2a and Cdkn2b, is severely reduced in chr4(Delta70kb/Delta70kb) mice, indicating that distant-acting gene regulatory functions are located in the non-coding CAD risk interval. Allele-specific expression of Cdkn2b transcripts in heterozygous mice showed that the deletion affects expression through a cis-acting mechanism. Primary cultures of chr4(Delta70kb/Delta70kb) aortic smooth muscle cells exhibited excessive proliferation and diminished senescence, a cellular phenotype consistent with accelerated CAD pathogenesis. Taken together, our results provide direct evidence that the CAD risk interval has a pivotal role in regulation of cardiac Cdkn2a/b expression, and suggest that this region affects CAD progression by altering the dynamics of vascular cell proliferation.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2938076/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2938076/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Visel, Axel -- Zhu, Yiwen -- May, Dalit -- Afzal, Veena -- Gong, Elaine -- Attanasio, Catia -- Blow, Matthew J -- Cohen, Jonathan C -- Rubin, Edward M -- Pennacchio, Len A -- DK59630/DK/NIDDK NIH HHS/ -- R01 HG003988/HG/NHGRI NIH HHS/ -- R01 HG003988-04/HG/NHGRI NIH HHS/ -- R01 HL082896/HL/NHLBI NIH HHS/ -- R01 HL082896-03/HL/NHLBI NIH HHS/ -- R21 HL098940/HL/NHLBI NIH HHS/ -- R21 HL098940-01/HL/NHLBI NIH HHS/ -- U01 HL066681/HL/NHLBI NIH HHS/ -- U01 HL066681-08/HL/NHLBI NIH HHS/ -- England -- Nature. 2010 Mar 18;464(7287):409-12. doi: 10.1038/nature08801.

    Description: The shape of the human face and skull is largely genetically determined. However, the genomic basis of craniofacial morphology is incompletely understood and hypothesized to involve protein-coding genes, as well as gene regulatory sequences. We used a combination of epigenomic profiling, in vivo characterization of candidate enhancer sequences in transgenic mice, and targeted deletion experiments to examine the role of distant-acting enhancers in craniofacial development. We identified complex regulatory landscapes consisting of enhancers that drive spatially complex developmental expression patterns. Analysis of mouse lines in which individual craniofacial enhancers had been deleted revealed significant alterations of craniofacial shape, demonstrating the functional importance of enhancers in defining face and skull morphology. These results demonstrate that enhancers are involved in craniofacial development and suggest that enhancer sequence variation contributes to the diversity of human facial morphology.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3991470/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3991470/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Attanasio, Catia -- Nord, Alex S -- Zhu, Yiwen -- Blow, Matthew J -- Li, Zirong -- Liberton, Denise K -- Morrison, Harris -- Plajzer-Frick, Ingrid -- Holt, Amy -- Hosseini, Roya -- Phouanenavong, Sengthavy -- Akiyama, Jennifer A -- Shoukry, Malak -- Afzal, Veena -- Rubin, Edward M -- FitzPatrick, David R -- Ren, Bing -- Hallgrimsson, Benedikt -- Pennacchio, Len A -- Visel, Axel -- 1R01DE01963/DE/NIDCR NIH HHS/ -- 1R01DE021708/DE/NIDCR NIH HHS/ -- 1U01DE020054/DE/NIDCR NIH HHS/ -- F32 GM105202/GM/NIGMS NIH HHS/ -- MC_PC_U127561093/Medical Research Council/United Kingdom -- MC_U127561093/Medical Research Council/United Kingdom -- R01 DE019638/DE/NIDCR NIH HHS/ -- R01 DE021708/DE/NIDCR NIH HHS/ -- R01 HG003988/HG/NHGRI NIH HHS/ -- R01 HG003991/HG/NHGRI NIH HHS/ -- R01HG003988/HG/NHGRI NIH HHS/ -- R01HG003991/HG/NHGRI NIH HHS/ -- U01 DE020054/DE/NIDCR NIH HHS/ -- U01 DE020060/DE/NIDCR NIH HHS/ -- U01DE020060/DE/NIDCR NIH HHS/ -- U54 HG006997/HG/NHGRI NIH HHS/ -- U54HG006997/HG/NHGRI NIH HHS/ -- Medical Research Council/United Kingdom -- New York, N.Y. -- Science. 2013 Oct 25;342(6157):1241006. doi: 10.1126/science.1241006.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Lawrence Berkeley National Laboratory, Berkeley, CA 94720, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/24159046" target="_blank"〉PubMed〈/a〉

    Description: To broaden our understanding of the evolution of gene regulation mechanisms, we generated occupancy profiles for 34 orthologous transcription factors (TFs) in human-mouse erythroid progenitor, lymphoblast and embryonic stem-cell lines. By combining the genome-wide transcription factor occupancy repertoires, associated epigenetic signals, and co-association patterns, here we deduce several evolutionary principles of gene regulatory features operating since the mouse and human lineages diverged. The genomic distribution profiles, primary binding motifs, chromatin states, and DNA methylation preferences are well conserved for TF-occupied sequences. However, the extent to which orthologous DNA segments are bound by orthologous TFs varies both among TFs and with genomic location: binding at promoters is more highly conserved than binding at distal elements. Notably, occupancy-conserved TF-occupied sequences tend to be pleiotropic; they function in several tissues and also co-associate with many TFs. Single nucleotide variants at sites with potential regulatory functions are enriched in occupancy-conserved TF-occupied sequences.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4343047/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4343047/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Cheng, Yong -- Ma, Zhihai -- Kim, Bong-Hyun -- Wu, Weisheng -- Cayting, Philip -- Boyle, Alan P -- Sundaram, Vasavi -- Xing, Xiaoyun -- Dogan, Nergiz -- Li, Jingjing -- Euskirchen, Ghia -- Lin, Shin -- Lin, Yiing -- Visel, Axel -- Kawli, Trupti -- Yang, Xinqiong -- Patacsil, Dorrelyn -- Keller, Cheryl A -- Giardine, Belinda -- Mouse ENCODE Consortium -- Kundaje, Anshul -- Wang, Ting -- Pennacchio, Len A -- Weng, Zhiping -- Hardison, Ross C -- Snyder, Michael P -- 1U54HG00699/HG/NHGRI NIH HHS/ -- 3RC2HG005602/HG/NHGRI NIH HHS/ -- 5U54HG006996/HG/NHGRI NIH HHS/ -- R01 DK065806/DK/NIDDK NIH HHS/ -- R01 DK096266/DK/NIDDK NIH HHS/ -- R01 ES024992/ES/NIEHS NIH HHS/ -- R01 EY021482/EY/NEI NIH HHS/ -- R01 GM083337/GM/NIGMS NIH HHS/ -- R01 HG003988/HG/NHGRI NIH HHS/ -- R01 HG004037/HG/NHGRI NIH HHS/ -- R01 HG007175/HG/NHGRI NIH HHS/ -- R01 HG007348/HG/NHGRI NIH HHS/ -- R01 HG007354/HG/NHGRI NIH HHS/ -- R01DK065806/DK/NIDDK NIH HHS/ -- R01HG003988/HG/NHGRI NIH HHS/ -- R37 DK044746/DK/NIDDK NIH HHS/ -- RC2 HG005573/HG/NHGRI NIH HHS/ -- RC2 HG005602/HG/NHGRI NIH HHS/ -- RC2HG005573/HG/NHGRI NIH HHS/ -- U01 DE024427/DE/NIDCR NIH HHS/ -- U41 HG007234/HG/NHGRI NIH HHS/ -- U54 HG006996/HG/NHGRI NIH HHS/ -- U54 HG006997/HG/NHGRI NIH HHS/ -- U54 HG006998/HG/NHGRI NIH HHS/ -- U54 HG007004/HG/NHGRI NIH HHS/ -- U54HG006997/HG/NHGRI NIH HHS/ -- England -- Nature. 2014 Nov 20;515(7527):371-5. doi: 10.1038/nature13985.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Genetics, Stanford University, Stanford, California 94305, USA. ; Program in Bioinformatics and Integrative Biology, Department of Biochemistry and Molecular Pharmacology, University of Massachusetts Medical School, Worcester, Massachusetts 01605, USA. ; 1] Center for Comparative Genomics and Bioinformatics, Huck Institutes of the Life Sciences, Department of Biochemistry and Molecular Biology, The Pennsylvania State University, University Park, Pennsylvania 16802, USA [2] BRCF Bioinformatics Core, University of Michigan, Ann Arbor, Michigan 48105, USA. ; Department of Genetics, Center for Genome Sciences and Systems Biology, Washington University School of Medicine, St Louis, Missouri 63108, USA. ; Center for Comparative Genomics and Bioinformatics, Huck Institutes of the Life Sciences, Department of Biochemistry and Molecular Biology, The Pennsylvania State University, University Park, Pennsylvania 16802, USA. ; 1] Department of Genetics, Stanford University, Stanford, California 94305, USA [2] Division of Cardiovascular Medicine, Stanford University, Stanford, California 94304, USA. ; 1] Department of Genetics, Stanford University, Stanford, California 94305, USA [2] Department of Surgery, Washington University School of Medicine, St Louis, Missouri 63110, USA. ; 1] Lawrence Berkeley National Laboratory, Genomics Division, Berkeley, California 94701, USA [2] Department of Energy Joint Genome Institute, Walnut Creek, California 94598, USA [3] School of Natural Sciences, University of California, Merced, California 95343, USA. ; 1] Lawrence Berkeley National Laboratory, Genomics Division, Berkeley, California 94701, USA [2] Department of Energy Joint Genome Institute, Walnut Creek, California 94598, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/25409826" target="_blank"〉PubMed〈/a〉

    Description: The discovery of rare genetic variants is accelerating, and clear guidelines for distinguishing disease-causing sequence variants from the many potentially functional variants present in any human genome are urgently needed. Without rigorous standards we risk an acceleration of false-positive reports of causality, which would impede the translation of genomic research findings into the clinical diagnostic setting and hinder biological understanding of disease. Here we discuss the key challenges of assessing sequence variants in human disease, integrating both gene-level and variant-level support for causality. We propose guidelines for summarizing confidence in variant pathogenicity and highlight several areas that require further resource development.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4180223/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4180223/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉MacArthur, D G -- Manolio, T A -- Dimmock, D P -- Rehm, H L -- Shendure, J -- Abecasis, G R -- Adams, D R -- Altman, R B -- Antonarakis, S E -- Ashley, E A -- Barrett, J C -- Biesecker, L G -- Conrad, D F -- Cooper, G M -- Cox, N J -- Daly, M J -- Gerstein, M B -- Goldstein, D B -- Hirschhorn, J N -- Leal, S M -- Pennacchio, L A -- Stamatoyannopoulos, J A -- Sunyaev, S R -- Valle, D -- Voight, B F -- Winckler, W -- Gunter, C -- P30 DK020595/DK/NIDDK NIH HHS/ -- P30 DK042086/DK/NIDDK NIH HHS/ -- R01 HG007022/HG/NHGRI NIH HHS/ -- R01 HL117626/HL/NHLBI NIH HHS/ -- R01 MH101810/MH/NIMH NIH HHS/ -- U54 HG006997/HG/NHGRI NIH HHS/ -- England -- Nature. 2014 Apr 24;508(7497):469-76. doi: 10.1038/nature13127.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉1] Analytic and Translational Genetics Unit, Massachusetts General Hospital, Boston, Massachusetts 02114, USA [2] Program in Medical and Population Genetics, Broad Institute of Harvard and MIT, Cambridge, Massachusetts 02142, USA. ;

    Description: The paucity of enzymes that efficiently deconstruct plant polysaccharides represents a major bottleneck for industrial-scale conversion of cellulosic biomass into biofuels. Cow rumen microbes specialize in degradation of cellulosic plant material, but most members of this complex community resist cultivation. To characterize biomass-degrading genes and genomes, we sequenced and analyzed 268 gigabases of metagenomic DNA from microbes adherent to plant fiber incubated in cow rumen. From these data, we identified 27,755 putative carbohydrate-active genes and expressed 90 candidate proteins, of which 57% were enzymatically active against cellulosic substrates. We also assembled 15 uncultured microbial genomes, which were validated by complementary methods including single-cell genome sequencing. These data sets provide a substantially expanded catalog of genes and genomes participating in the deconstruction of cellulosic biomass.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hess, Matthias -- Sczyrba, Alexander -- Egan, Rob -- Kim, Tae-Wan -- Chokhawala, Harshal -- Schroth, Gary -- Luo, Shujun -- Clark, Douglas S -- Chen, Feng -- Zhang, Tao -- Mackie, Roderick I -- Pennacchio, Len A -- Tringe, Susannah G -- Visel, Axel -- Woyke, Tanja -- Wang, Zhong -- Rubin, Edward M -- New York, N.Y. -- Science. 2011 Jan 28;331(6016):463-7. doi: 10.1126/science.1200387.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Energy, Joint Genome Institute, Walnut Creek, CA 94598, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/21273488" target="_blank"〉PubMed〈/a〉

    Description: Motivation: The sequencing of over a thousand natural strains of the model plant Arabidopsis thaliana is producing unparalleled information at the genetic level for plant researchers. To enable the rapid exploitation of these data for functional proteomics studies, we have created a resource for the visualization of protein information and proteomic datasets for sequenced natural strains of A. thaliana . Results: The 1001 Proteomes portal can be used to visualize amino acid substitutions or non-synonymous single-nucleotide polymorphisms in individual proteins of A. thaliana based on the reference genome Col-0. We have used the available processed sequence information to analyze the conservation of known residues subject to protein phosphorylation among these natural strains. The substitution of amino acids in A. thaliana natural strains is heavily constrained and is likely a result of the conservation of functional attributes within proteins. At a practical level, we demonstrate that this information can be used to clarify ambiguously defined phosphorylation sites from phosphoproteomic studies. Protein sets of available natural variants are available for download to enable proteomic studies on these accessions. Together this information can be used to uncover the possible roles of specific amino acids in determining the structure and function of proteins in the model plant A. thaliana . An online portal to enable the community to exploit these data can be accessed at http://1001proteomes.masc-proteomics.org/ Contact: jlheazlewood@lbl.gov Supplementary information: Supplementary data are available at Bioinformatics online.

    Description: DNA variation in Interferon Regulatory Factor 6 ( IRF6 ) causes Van der Woude syndrome (VWS), the most common syndromic form of cleft lip and palate (CLP). However, an etiologic variant in IRF6 has been found in only 70% of VWS families. To test whether DNA variants in regulatory elements cause VWS, we sequenced three conserved elements near IRF6 in 70 VWS families that lack an etiologic mutation within IRF6 exons. A rare mutation ( 350dupA ) was found in a conserved IRF6 enhancer element ( MCS9.7 ) in a Brazilian family. The 350dupA mutation abrogated the binding of p63 and E47 transcription factors to cis-overlapping motifs, and significantly disrupted enhancer activity in human cell cultures. Moreover, using a transgenic assay in mice, the 350dupA mutation disrupted the activation of MCS9.7 enhancer element and led to failure of lacZ expression in all head and neck pharyngeal arches. Interestingly, disruption of the p63 Motif1 and/or E47 binding sites by nucleotide substitution did not fully recapitulate the effect of the 350dupA mutation. Rather, we recognized that the 350dupA created a CAAAGT motif, a binding site for Lef1 protein. We showed that Lef1 binds to the mutated site and that overexpression of Lef1/β-Catenin chimeric protein repressed MCS9.7-350dupA enhancer activity. In conclusion, our data strongly suggest that 350dupA variant is an etiologic mutation in VWS patients and disrupts enhancer activity by a loss- and gain-of-function mechanism, and thus support the rationale for additional screening for regulatory mutations in patients with CLP.
