Item Open Access A high-resolution map of human evolutionary constraint using 29 mammals.(Nature, 2011-10-12) Lindblad-Toh, Kerstin; Garber, Manuel; Zuk, Or; Lin, Michael F; Parker, Brian J; Washietl, Stefan; Kheradpour, Pouya; Ernst, Jason; Jordan, Gregory; Mauceli, Evan; Ward, Lucas D; Lowe, Craig B; Holloway, Alisha K; Clamp, Michele; Gnerre, Sante; Alföldi, Jessica; Beal, Kathryn; Chang, Jean; Clawson, Hiram; Cuff, James; Di Palma, Federica; Fitzgerald, Stephen; Flicek, Paul; Guttman, Mitchell; Hubisz, Melissa J; Jaffe, David B; Jungreis, Irwin; Kent, W James; Kostka, Dennis; Lara, Marcia; Martins, Andre L; Massingham, Tim; Moltke, Ida; Raney, Brian J; Rasmussen, Matthew D; Robinson, Jim; Stark, Alexander; Vilella, Albert J; Wen, Jiayu; Xie, Xiaohui; Zody, Michael C; Broad Institute Sequencing Platform and Whole Genome Assembly Team; Baldwin, Jen; Bloom, Toby; Chin, Chee Whye; Heiman, Dave; Nicol, Robert; Nusbaum, Chad; Young, Sarah; Wilkinson, Jane; Worley, Kim C; Kovar, Christie L; Muzny, Donna M; Gibbs, Richard A; Baylor College of Medicine Human Genome Sequencing Center Sequencing Team; Cree, Andrew; Dihn, Huyen H; Fowler, Gerald; Jhangiani, Shalili; Joshi, Vandita; Lee, Sandra; Lewis, Lora R; Nazareth, Lynne V; Okwuonu, Geoffrey; Santibanez, Jireh; Warren, Wesley C; Mardis, Elaine R; Weinstock, George M; Wilson, Richard K; Genome Institute at Washington University; Delehaunty, Kim; Dooling, David; Fronik, Catrina; Fulton, Lucinda; Fulton, Bob; Graves, Tina; Minx, Patrick; Sodergren, Erica; Birney, Ewan; Margulies, Elliott H; Herrero, Javier; Green, Eric D; Haussler, David; Siepel, Adam; Goldman, Nick; Pollard, Katherine S; Pedersen, Jakob S; Lander, Eric S; Kellis, ManolisThe comparison of related genomes has emerged as a powerful lens for genome interpretation. Here we report the sequencing and comparative analysis of 29 eutherian genomes. We confirm that at least 5.5% of the human genome has undergone purifying selection, and locate constrained elements covering ∼4.2% of the genome. We use evolutionary signatures and comparisons with experimental data sets to suggest candidate functions for ∼60% of constrained bases. These elements reveal a small number of new coding exons, candidate stop codon readthrough events and over 10,000 regions of overlapping synonymous constraint within protein-coding exons. We find 220 candidate RNA structural families, and nearly a million elements overlapping potential promoter, enhancer and insulator regions. We report specific amino acid residues that have undergone positive selection, 280,000 non-coding elements exapted from mobile elements and more than 1,000 primate- and human-accelerated elements. Overlap with disease-associated variants indicates that our findings will be relevant for studies of human biology, health and disease.Item Open Access A widespread length-dependent splicing dysregulation in cancer.(Science advances, 2022-08) Zhang, Sirui; Mao, Miaowei; Lv, Yuesheng; Yang, Yingqun; He, Weijing; Song, Yongmei; Wang, Yongbo; Yang, Yun; Al Abo, Muthana; Freedman, Jennifer A; Patierno, Steven R; Wang, Yang; Wang, ZefengDysregulation of alternative splicing is a key molecular hallmark of cancer. However, the common features and underlying mechanisms remain unclear. Here, we report an intriguing length-dependent splicing regulation in cancers. By systematically analyzing the transcriptome of thousands of cancer patients, we found that short exons are more likely to be mis-spliced and preferentially excluded in cancers. Compared to other exons, cancer-associated short exons (CASEs) are more conserved and likely to encode in-frame low-complexity peptides, with functional enrichment in GTPase regulators and cell adhesion. We developed a CASE-based panel as reliable cancer stratification markers and strong predictors for survival, which is clinically useful because the detection of short exon splicing is practical. Mechanistically, mis-splicing of CASEs is regulated by elevated transcription and alteration of certain RNA binding proteins in cancers. Our findings uncover a common feature of cancer-specific splicing dysregulation with important clinical implications in cancer diagnosis and therapies.Item Open Access Alternative splicing in multiple sclerosis and other autoimmune diseases.(RNA Biol, 2010-07) Evsyukova, Irina; Somarelli, Jason A; Gregory, Simon G; Garcia-Blanco, Mariano AAlternative splicing is a general mechanism for regulating gene expression that affects the RNA products of more than 90% of human genes. Not surprisingly, alternative splicing is observed among gene products of metazoan immune systems, which have evolved to efficiently recognize pathogens and discriminate between "self" and "non-self", and thus need to be both diverse and flexible. In this review we focus on the specific interface between alternative splicing and autoimmune diseases, which result from a malfunctioning of the immune system and are characterized by the inappropriate reaction to self-antigens. Despite the widespread recognition of alternative splicing as one of the major regulators of gene expression, the connections between alternative splicing and autoimmunity have not been apparent. We summarize recent findings connecting splicing and autoimmune disease, and attempt to find common patterns of splicing regulation that may advance our understanding of autoimmune diseases and open new avenues for therapy.Item Open Access Drosophila muller f elements maintain a distinct set of genomic properties over 40 million years of evolution.(G3 (Bethesda, Md.), 2015-03-04) Leung, Wilson;

Elgin, Sarah CRThe Muller F element (4.2 Mb, ~80 protein-coding genes) is an unusual autosome of Drosophila melanogaster; it is mostly heterochromatic with a low recombination rate. To investigate how these properties impact the evolution of repeats and genes, we manually improved the sequence and annotated the genes on the D. erecta, D. mojavensis, and D. grimshawi F elements and euchromatic domains from the Muller D element. We find that F elements have greater transposon density (25-50%) than euchromatic reference regions (3-11%). Among the F elements, D. grimshawi has the lowest transposon density (particularly DINE-1: 2% vs. 11-27%). F element genes have larger coding spans, more coding exons, larger introns, and lower codon bias. Comparison of the Effective Number of Codons with the Codon Adaptation Index shows that, in contrast to the other species, codon bias in D. grimshawi F element genes can be attributed primarily to selection instead of mutational biases, suggesting that density and types of transposons affect the degree of local heterochromatin formation. F element genes have lower estimated DNA melting temperatures than D element genes, potentially facilitating transcription through heterochromatin. Most F element genes (~90%) have remained on that element, but the F element has smaller syntenic blocks than genome averages (3.4-3.6 vs. 8.4-8.8 genes per block), indicating greater rates of inversion despite lower rates of recombination. Overall, the F element has maintained characteristics that are distinct from other autosomes in the Drosophila lineage, illuminating the constraints imposed by a heterochromatic milieu.Item Open Access Essential role of beta-adrenergic receptor kinase 1 in cardiac development and function.(Proc Natl Acad Sci U S A, 1996-11-12) Jaber, M; Koch, WJ; Rockman, H; Smith, B; Bond, RA; Sulik, KK; Ross, J; Lefkowitz, RJ; Caron, MG; Giros, BThe beta-adrenergic receptor kinase 1 (beta ARK1) is a member of the G protein-coupled receptor kinase (GRK) family that mediates the agonist-dependent phosphorylation and desensitization of G protein-coupled receptors. We have cloned and disrupted the beta ARK1 gene in mice by homologous recombination. No homozygote beta ARK1-/- embryos survive beyond gestational day 15.5. Prior to gestational day 15.5, beta ARK1-/- embryos display pronounced hypoplasia of the ventricular myocardium essentially identical to the "thin myocardium syndrome" observed upon gene inactivation of several transcription factors (RXR alpha, N-myc, TEF-1, WT-1). Lethality in beta ARK1-/- embryos is likely due to heart failure as they exhibit a > 70% decrease in cardiac ejection fraction determined by direct in utero intravital microscopy. These results along with the virtual absence of endogenous GRK activity in beta ARK1-/- embryos demonstrate that beta ARK1 appears to be the predominant GRK in early embryogenesis and that it plays a fundamental role in cardiac development.Item Open Access Genome-wide analyses of exonic copy number variants in a family-based study point to novel autism susceptibility genes.(PLoS Genet, 2009-06) Bucan, Maja; Abrahams, Brett S; Wang, Kai; Glessner, Joseph T; Herman, Edward I; Sonnenblick, Lisa I; Alvarez Retuerto, Ana I; Imielinski, Marcin; Hadley, Dexter; Bradfield, Jonathan P; Kim, Cecilia; Gidaya, Nicole B; Lindquist, Ingrid; Hutman, Ted; Sigman, Marian; Kustanovich, Vlad; Lajonchere, Clara M; Singleton, Andrew; Kim, Junhyong; Wassink, Thomas H; McMahon, William M; Owley, Thomas; Sweeney, John A; Coon, Hilary; Nurnberger, John I; Li, Mingyao; Cantor, Rita M; Minshew, Nancy J; Sutcliffe, James S; Cook, Edwin H; Dawson, Geraldine; Buxbaum, Joseph D; Grant, Struan FA; Schellenberg, Gerard D; Geschwind, Daniel H; Hakonarson, HakonThe genetics underlying the autism spectrum disorders (ASDs) is complex and remains poorly understood. Previous work has demonstrated an important role for structural variation in a subset of cases, but has lacked the resolution necessary to move beyond detection of large regions of potential interest to identification of individual genes. To pinpoint genes likely to contribute to ASD etiology, we performed high density genotyping in 912 multiplex families from the Autism Genetics Resource Exchange (AGRE) collection and contrasted results to those obtained for 1,488 healthy controls. Through prioritization of exonic deletions (eDels), exonic duplications (eDups), and whole gene duplication events (gDups), we identified more than 150 loci harboring rare variants in multiple unrelated probands, but no controls. Importantly, 27 of these were confirmed on examination of an independent replication cohort comprised of 859 cases and an additional 1,051 controls. Rare variants at known loci, including exonic deletions at NRXN1 and whole gene duplications encompassing UBE3A and several other genes in the 15q11-q13 region, were observed in the course of these analyses. Strong support was likewise observed for previously unreported genes such as BZRAP1, an adaptor molecule known to regulate synaptic transmission, with eDels or eDups observed in twelve unrelated cases but no controls (p = 2.3x10(-5)). Less is known about MDGA2, likewise observed to be case-specific (p = 1.3x10(-4)). But, it is notable that the encoded protein shows an unexpectedly high similarity to Contactin 4 (BLAST E-value = 3x10(-39)), which has also been linked to disease. That hundreds of distinct rare variants were each seen only once further highlights complexity in the ASDs and points to the continued need for larger cohorts.Item Open Access Mutational profile and prognostic significance of TP53 in diffuse large B-cell lymphoma patients treated with R-CHOP: report from an International DLBCL Rituximab-CHOP Consortium Program Study.(Blood, 2012-11) Xu-Monette, Zijun Y; Wu, Lin; Visco, Carlo; Tai, Yu Chuan; Tzankov, Alexander; Liu, Wei-min; Montes-Moreno, Santiago; Dybkaer, Karen; Chiu, April; Orazi, Attilio; Zu, Youli; Bhagat, Govind; Richards, Kristy L; Hsi, Eric D; Zhao, X Frank; Choi, William WL; Zhao, Xiaoying; van Krieken, J Han; Huang, Qin; Huh, Jooryung; Ai, Weiyun; Ponzoni, Maurilio; Ferreri, Andrés JM; Zhou, Fan; Kahl, Brad S; Winter, Jane N; Xu, Wei; Li, Jianyong; Go, Ronald S; Li, Yong; Piris, Miguel A; Møller, Michael B; Miranda, Roberto N; Abruzzo, Lynne V; Medeiros, L Jeffrey; Young, Ken HTP53 mutation is an independent marker of poor prognosis in patients with diffuse large B-cell lymphoma (DLBCL) treated with cyclophosphamide, hydroxydaunorubicin, vincristine, and prednisone (CHOP) therapy. However, its prognostic value in the rituximab immunochemotherapy era remains undefined. In the present study of a large cohort of DLBCL patients treated with rituximab plus CHOP (R-CHOP), we show that those with TP53 mutations had worse overall and progression-free survival compared with those without. Unlike earlier studies of patients treated with CHOP, TP53 mutation has predictive value for R-CHOP-treated patients with either the germinal center B-cell or activated B-cell DLBCL subtypes. Furthermore, we identified the loop-sheet-helix and L3 motifs in the DNA-binding domain to be the most critical structures for maintaining p53 function. In contrast, TP53 deletion and loss of heterozygosity did not confer worse survival. If gene mutation data are not available, immunohistochemical analysis showing > 50% cells expressing p53 protein is a useful surrogate and was able to stratify patients with significantly different prognoses. We conclude that assessment of TP53 mutation status is important for stratifying R-CHOP-treated patients into distinct prognostic subsets and has significant value in the design of future therapeutic strategies.Item Open Access Nutritional control of mRNA isoform expression during developmental arrest and recovery in C. elegans.(Genome Res, 2012-10) Maxwell, Colin S; Antoshechkin, Igor; Kurhanewicz, Nicole; Belsky, Jason A; Baugh, L RyanNutrient availability profoundly influences gene expression. Many animal genes encode multiple transcript isoforms, yet the effect of nutrient availability on transcript isoform expression has not been studied in genome-wide fashion. When Caenorhabditis elegans larvae hatch without food, they arrest development in the first larval stage (L1 arrest). Starved larvae can survive L1 arrest for weeks, but growth and post-embryonic development are rapidly initiated in response to feeding. We used RNA-seq to characterize the transcriptome during L1 arrest and over time after feeding. Twenty-seven percent of detectable protein-coding genes were differentially expressed during recovery from L1 arrest, with the majority of changes initiating within the first hour, demonstrating widespread, acute effects of nutrient availability on gene expression. We used two independent approaches to track expression of individual exons and mRNA isoforms, and we connected changes in expression to functional consequences by mining a variety of databases. These two approaches identified an overlapping set of genes with alternative isoform expression, and they converged on common functional patterns. Genes affecting mRNA splicing and translation are regulated by alternative isoform expression, revealing post-transcriptional consequences of nutrient availability on gene regulation. We also found that phosphorylation sites are often alternatively expressed, revealing a common mode by which alternative isoform expression modifies protein function and signal transduction. Our results detail rich changes in C. elegans gene expression as larvae initiate growth and post-embryonic development, and they provide an excellent resource for ongoing investigation of transcriptional regulation and developmental physiology.Item Open Access Screening the human exome: a comparison of whole genome and whole transcriptome sequencing.(Genome Biol, 2010) Cirulli, Elizabeth T; Singh, Abanish; Shianna, Kevin V; Ge, Dongliang; Smith, Jason P; Maia, Jessica M; Heinzen, Erin L; Goedert, James J; Goldstein, David B; Center for HIV/AIDS Vaccine Immunology (CHAVI)BACKGROUND: There is considerable interest in the development of methods to efficiently identify all coding variants present in large sample sets of humans. There are three approaches possible: whole-genome sequencing, whole-exome sequencing using exon capture methods, and RNA-Seq. While whole-genome sequencing is the most complete, it remains sufficiently expensive that cost effective alternatives are important. RESULTS: Here we provide a systematic exploration of how well RNA-Seq can identify human coding variants by comparing variants identified through high coverage whole-genome sequencing to those identified by high coverage RNA-Seq in the same individual. This comparison allowed us to directly evaluate the sensitivity and specificity of RNA-Seq in identifying coding variants, and to evaluate how key parameters such as the degree of coverage and the expression levels of genes interact to influence performance. We find that although only 40% of exonic variants identified by whole genome sequencing were captured using RNA-Seq; this number rose to 81% when concentrating on genes known to be well-expressed in the source tissue. We also find that a high false positive rate can be problematic when working with RNA-Seq data, especially at higher levels of coverage. CONCLUSIONS: We conclude that as long as a tissue relevant to the trait under study is available and suitable quality control screens are implemented, RNA-Seq is a fast and inexpensive alternative approach for finding coding variants in genes with sufficiently high expression levels.Item Open Access SplicerEX: a tool for the automated detection and classification of mRNA changes from conventional and splice-sensitive microarray expression data.(RNA (New York, N.Y.), 2012-08) Robinson, Timothy J; Forte, Eleonora; Salinas, Raul E; Puri, Shaan; Marengo, Matthew; Garcia-Blanco, Mariano A; Luftig, Micah AThe key postulate that one gene encodes one protein has been overhauled with the discovery that one gene can generate multiple RNA transcripts through alternative mRNA processing. In this study, we describe SplicerEX, a novel and uniquely motivated algorithm designed for experimental biologists that (1) detects widespread changes in mRNA isoforms from both conventional and splice sensitive microarray data, (2) automatically categorizes mechanistic changes in mRNA processing, and (3) mitigates known technological artifacts of exon array-based detection of alternative splicing resulting from 5' and 3' signal attenuation, background detection limits, and saturation of probe set signal intensity. In this study, we used SplicerEX to compare conventional and exon-based Affymetrix microarray data in a model of EBV transformation of primary human B cells. We demonstrated superior detection of 3'-located changes in mRNA processing by the Affymetrix U133 GeneChip relative to the Human Exon Array. SplicerEX-identified exon-level changes in the EBV infection model were confirmed by RT-PCR and revealed a novel set of EBV-regulated mRNA isoform changes in caspases 6, 7, and 8. Finally, SplicerEX as compared with MiDAS analysis of publicly available microarray data provided more efficiently categorized mRNA isoform changes with a significantly higher proportion of hits supported by previously annotated alternative processing events. Therefore, SplicerEX provides an important tool for the biologist interested in studying changes in mRNA isoform usage from conventional or splice-sensitive microarray platforms, especially considering the expansive amount of archival microarray data generated over the past decade. SplicerEX is freely available upon request.Item Open Access The characterization of twenty sequenced human genomes.(PLoS Genet, 2010-09-09) Pelak, Kimberly; Shianna, Kevin V; Ge, Dongliang; Maia, Jessica M; Zhu, Mingfu; Smith, Jason P; Cirulli, Elizabeth T; Fellay, Jacques; Dickson, Samuel P; Gumbs, Curtis E; Heinzen, Erin L; Need, Anna C; Ruzzo, Elizabeth K; Singh, Abanish; Campbell, C Ryan; Hong, Linda K; Lornsen, Katharina A; McKenzie, Alexander M; Sobreira, Nara LM; Hoover-Fong, Julie E; Milner, Joshua D; Ottman, Ruth; Haynes, Barton F; Goedert, James J; Goldstein, David BWe present the analysis of twenty human genomes to evaluate the prospects for identifying rare functional variants that contribute to a phenotype of interest. We sequenced at high coverage ten "case" genomes from individuals with severe hemophilia A and ten "control" genomes. We summarize the number of genetic variants emerging from a study of this magnitude, and provide a proof of concept for the identification of rare and highly-penetrant functional variants by confirming that the cause of hemophilia A is easily recognizable in this data set. We also show that the number of novel single nucleotide variants (SNVs) discovered per genome seems to stabilize at about 144,000 new variants per genome, after the first 15 individuals have been sequenced. Finally, we find that, on average, each genome carries 165 homozygous protein-truncating or stop loss variants in genes representing a diverse set of pathways.Item Open Access Tissue-specific genetic control of splicing: implications for the study of complex traits.(PLoS Biol, 2008-12-23) Heinzen, Erin L; Ge, Dongliang; Cronin, Kenneth D; Maia, Jessica M; Shianna, Kevin V; Gabriel, Willow N; Welsh-Bohmer, Kathleen A; Hulette, Christine M; Denny, Thomas N; Goldstein, David BNumerous genome-wide screens for polymorphisms that influence gene expression have provided key insights into the genetic control of transcription. Despite this work, the relevance of specific polymorphisms to in vivo expression and splicing remains unclear. We carried out the first genome-wide screen, to our knowledge, for SNPs that associate with alternative splicing and gene expression in human primary cells, evaluating 93 autopsy-collected cortical brain tissue samples with no defined neuropsychiatric condition and 80 peripheral blood mononucleated cell samples collected from living healthy donors. We identified 23 high confidence associations with total expression and 80 with alternative splicing as reflected by expression levels of specific exons. Fewer than 50% of the implicated SNPs however show effects in both tissue types, reflecting strong evidence for distinct genetic control of splicing and expression in the two tissue types. The data generated here also suggest the possibility that splicing effects may be responsible for up to 13 out of 84 reported genome-wide significant associations with human traits. These results emphasize the importance of establishing a database of polymorphisms affecting splicing and expression in primary tissue types and suggest that splicing effects may be of more phenotypic significance than overall gene expression changes.
