    Strict evolutionary conservation followed rapid gene loss on human and rhesus Y chromosomes (2012)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2012-03-01
    Description: The human X and Y chromosomes evolved from an ordinary pair of autosomes during the past 200-300 million years. The human MSY (male-specific region of Y chromosome) retains only three percent of the ancestral autosomes' genes owing to genetic decay. This evolutionary decay was driven by a series of five 'stratification' events. Each event suppressed X-Y crossing over within a chromosome segment or 'stratum', incorporated that segment into the MSY and subjected its genes to the erosive forces that attend the absence of crossing over. The last of these events occurred 30 million years ago, 5 million years before the human and Old World monkey lineages diverged. Although speculation abounds regarding ongoing decay and looming extinction of the human Y chromosome, remarkably little is known about how many MSY genes were lost in the human lineage in the 25 million years that have followed its separation from the Old World monkey lineage. To investigate this question, we sequenced the MSY of the rhesus macaque, an Old World monkey, and compared it to the human MSY. We discovered that during the last 25 million years MSY gene loss in the human lineage was limited to the youngest stratum (stratum 5), which comprises three percent of the human MSY. In the older strata, which collectively comprise the bulk of the human MSY, gene loss evidently ceased more than 25 million years ago. Likewise, the rhesus MSY has not lost any older genes (from strata 1-4) during the past 25 million years, despite its major structural differences to the human MSY. The rhesus MSY is simpler, with few amplified gene families or palindromes that might enable intrachromosomal recombination and repair. We present an empirical reconstruction of human MSY evolution in which each stratum transitioned from rapid, exponential loss of ancestral genes to strict conservation through purifying selection.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3292678/" 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/PMC3292678/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hughes, Jennifer F -- Skaletsky, Helen -- Brown, Laura G -- Pyntikova, Tatyana -- Graves, Tina -- Fulton, Robert S -- Dugan, Shannon -- Ding, Yan -- Buhay, Christian J -- Kremitzki, Colin -- Wang, Qiaoyan -- Shen, Hua -- Holder, Michael -- Villasana, Donna -- Nazareth, Lynne V -- Cree, Andrew -- Courtney, Laura -- Veizer, Joelle -- Kotkiewicz, Holland -- Cho, Ting-Jan -- Koutseva, Natalia -- Rozen, Steve -- Muzny, Donna M -- Warren, Wesley C -- Gibbs, Richard A -- Wilson, Richard K -- Page, David C -- R01 HG000257/HG/NHGRI NIH HHS/ -- R01 HG000257-17/HG/NHGRI NIH HHS/ -- U54 HG003273/HG/NHGRI NIH HHS/ -- Howard Hughes Medical Institute/ -- England -- Nature. 2012 Feb 22;483(7387):82-6. doi: 10.1038/nature10843.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute, Department of Biology, Massachusetts Institute of Technology, 9 Cambridge Center, Cambridge, Massachusetts 02142, USA. jhughes@wi.mit.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22367542" target="_blank"〉PubMed〈/a〉

    Alveolar progenitor and stem cells in lung development, renewal and cancer (2014)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2014-02-07
    Description: Alveoli are gas-exchange sacs lined by squamous alveolar type (AT) 1 cells and cuboidal, surfactant-secreting AT2 cells. Classical studies suggested that AT1 arise from AT2 cells, but recent studies propose other sources. Here we use molecular markers, lineage tracing and clonal analysis to map alveolar progenitors throughout the mouse lifespan. We show that, during development, AT1 and AT2 cells arise directly from a bipotent progenitor, whereas after birth new AT1 cells derive from rare, self-renewing, long-lived, mature AT2 cells that produce slowly expanding clonal foci of alveolar renewal. This stem-cell function is broadly activated by AT1 injury, and AT2 self-renewal is selectively induced by EGFR (epidermal growth factor receptor) ligands in vitro and oncogenic Kras(G12D) in vivo, efficiently generating multifocal, clonal adenomas. Thus, there is a switch after birth, when AT2 cells function as stem cells that contribute to alveolar renewal, repair and cancer. We propose that local signals regulate AT2 stem-cell activity: a signal transduced by EGFR-KRAS controls self-renewal and is hijacked during oncogenesis, whereas another signal controls reprogramming to AT1 fate.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4013278/" 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/PMC4013278/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Desai, Tushar J -- Brownfield, Douglas G -- Krasnow, Mark A -- P30 CA124435/CA/NCI NIH HHS/ -- U01 HL099995/HL/NHLBI NIH HHS/ -- U01 HL099999/HL/NHLBI NIH HHS/ -- England -- Nature. 2014 Mar 13;507(7491):190-4. doi: 10.1038/nature12930.

    Interferon-gamma links ultraviolet radiation to melanomagenesis in mice (2011)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2011-01-21
    Description: Cutaneous malignant melanoma is a highly aggressive and frequently chemoresistant cancer, the incidence of which continues to rise. Epidemiological studies show that the major aetiological melanoma risk factor is ultraviolet (UV) solar radiation, with the highest risk associated with intermittent burning doses, especially during childhood. We have experimentally validated these epidemiological findings using the hepatocyte growth factor/scatter factor transgenic mouse model, which develops lesions in stages highly reminiscent of human melanoma with respect to biological, genetic and aetiological criteria, but only when irradiated as neonatal pups with UVB, not UVA. However, the mechanisms underlying UVB-initiated, neonatal-specific melanomagenesis remain largely unknown. Here we introduce a mouse model permitting fluorescence-aided melanocyte imaging and isolation following in vivo UV irradiation. We use expression profiling to show that activated neonatal skin melanocytes isolated following a melanomagenic UVB dose bear a distinct, persistent interferon response signature, including genes associated with immunoevasion. UVB-induced melanocyte activation, characterized by aberrant growth and migration, was abolished by antibody-mediated systemic blockade of interferon-gamma (IFN-gamma), but not type-I interferons. IFN-gamma was produced by macrophages recruited to neonatal skin by UVB-induced ligands to the chemokine receptor Ccr2. Admixed recruited skin macrophages enhanced transplanted melanoma growth by inhibiting apoptosis; notably, IFN-gamma blockade abolished macrophage-enhanced melanoma growth and survival. IFN-gamma-producing macrophages were also identified in 70% of human melanomas examined. Our data reveal an unanticipated role for IFN-gamma in promoting melanocytic cell survival/immunoevasion, identifying a novel candidate therapeutic target for a subset of melanoma patients.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3140101/" 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/PMC3140101/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Zaidi, M Raza -- Davis, Sean -- Noonan, Frances P -- Graff-Cherry, Cari -- Hawley, Teresa S -- Walker, Robert L -- Feigenbaum, Lionel -- Fuchs, Elaine -- Lyakh, Lyudmila -- Young, Howard A -- Hornyak, Thomas J -- Arnheiter, Heinz -- Trinchieri, Giorgio -- Meltzer, Paul S -- De Fabo, Edward C -- Merlino, Glenn -- CA53765/CA/NCI NIH HHS/ -- CA92258/CA/NCI NIH HHS/ -- R01 CA053765-10S1/CA/NCI NIH HHS/ -- R01 CA092258-05/CA/NCI NIH HHS/ -- Intramural NIH HHS/ -- England -- Nature. 2011 Jan 27;469(7331):548-53. doi: 10.1038/nature09666.

    Initial genome sequencing and analysis of multiple myeloma (2011)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2011-03-25
    Description: Multiple myeloma is an incurable malignancy of plasma cells, and its pathogenesis is poorly understood. Here we report the massively parallel sequencing of 38 tumour genomes and their comparison to matched normal DNAs. Several new and unexpected oncogenic mechanisms were suggested by the pattern of somatic mutation across the data set. These include the mutation of genes involved in protein translation (seen in nearly half of the patients), genes involved in histone methylation, and genes involved in blood coagulation. In addition, a broader than anticipated role of NF-kappaB signalling was indicated by mutations in 11 members of the NF-kappaB pathway. Of potential immediate clinical relevance, activating mutations of the kinase BRAF were observed in 4% of patients, suggesting the evaluation of BRAF inhibitors in multiple myeloma clinical trials. These results indicate that cancer genome sequencing of large collections of samples will yield new insights into cancer not anticipated by existing knowledge.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3560292/" 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/PMC3560292/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chapman, Michael A -- Lawrence, Michael S -- Keats, Jonathan J -- Cibulskis, Kristian -- Sougnez, Carrie -- Schinzel, Anna C -- Harview, Christina L -- Brunet, Jean-Philippe -- Ahmann, Gregory J -- Adli, Mazhar -- Anderson, Kenneth C -- Ardlie, Kristin G -- Auclair, Daniel -- Baker, Angela -- Bergsagel, P Leif -- Bernstein, Bradley E -- Drier, Yotam -- Fonseca, Rafael -- Gabriel, Stacey B -- Hofmeister, Craig C -- Jagannath, Sundar -- Jakubowiak, Andrzej J -- Krishnan, Amrita -- Levy, Joan -- Liefeld, Ted -- Lonial, Sagar -- Mahan, Scott -- Mfuko, Bunmi -- Monti, Stefano -- Perkins, Louise M -- Onofrio, Robb -- Pugh, Trevor J -- Rajkumar, S Vincent -- Ramos, Alex H -- Siegel, David S -- Sivachenko, Andrey -- Stewart, A Keith -- Trudel, Suzanne -- Vij, Ravi -- Voet, Douglas -- Winckler, Wendy -- Zimmerman, Todd -- Carpten, John -- Trent, Jeff -- Hahn, William C -- Garraway, Levi A -- Meyerson, Matthew -- Lander, Eric S -- Getz, Gad -- Golub, Todd R -- K12 CA133250/CA/NCI NIH HHS/ -- R01 AG020686/AG/NIA NIH HHS/ -- R01 AG020686-07/AG/NIA NIH HHS/ -- R01 CA133115/CA/NCI NIH HHS/ -- R01 CA133115-04/CA/NCI NIH HHS/ -- R01 CA133966/CA/NCI NIH HHS/ -- R01 CA133966-03/CA/NCI NIH HHS/ -- England -- Nature. 2011 Mar 24;471(7339):467-72. doi: 10.1038/nature09837.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉The Eli and Edythe L.

    The genomic complexity of primary human prostate cancer (2011)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2011-02-11
    Description: Prostate cancer is the second most common cause of male cancer deaths in the United States. However, the full range of prostate cancer genomic alterations is incompletely characterized. Here we present the complete sequence of seven primary human prostate cancers and their paired normal counterparts. Several tumours contained complex chains of balanced (that is, 'copy-neutral') rearrangements that occurred within or adjacent to known cancer genes. Rearrangement breakpoints were enriched near open chromatin, androgen receptor and ERG DNA binding sites in the setting of the ETS gene fusion TMPRSS2-ERG, but inversely correlated with these regions in tumours lacking ETS fusions. This observation suggests a link between chromatin or transcriptional regulation and the genesis of genomic aberrations. Three tumours contained rearrangements that disrupted CADM2, and four harboured events disrupting either PTEN (unbalanced events), a prostate tumour suppressor, or MAGI2 (balanced events), a PTEN interacting protein not previously implicated in prostate tumorigenesis. Thus, genomic rearrangements may arise from transcriptional or chromatin aberrancies and engage prostate tumorigenic mechanisms.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3075885/" 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/PMC3075885/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Berger, Michael F -- Lawrence, Michael S -- Demichelis, Francesca -- Drier, Yotam -- Cibulskis, Kristian -- Sivachenko, Andrey Y -- Sboner, Andrea -- Esgueva, Raquel -- Pflueger, Dorothee -- Sougnez, Carrie -- Onofrio, Robert -- Carter, Scott L -- Park, Kyung -- Habegger, Lukas -- Ambrogio, Lauren -- Fennell, Timothy -- Parkin, Melissa -- Saksena, Gordon -- Voet, Douglas -- Ramos, Alex H -- Pugh, Trevor J -- Wilkinson, Jane -- Fisher, Sheila -- Winckler, Wendy -- Mahan, Scott -- Ardlie, Kristin -- Baldwin, Jennifer -- Simons, Jonathan W -- Kitabayashi, Naoki -- MacDonald, Theresa Y -- Kantoff, Philip W -- Chin, Lynda -- Gabriel, Stacey B -- Gerstein, Mark B -- Golub, Todd R -- Meyerson, Matthew -- Tewari, Ashutosh -- Lander, Eric S -- Getz, Gad -- Rubin, Mark A -- Garraway, Levi A -- 2 P50 CA090381-11/CA/NCI NIH HHS/ -- DP2 OD002750/OD/NIH HHS/ -- DP2 OD002750-01/OD/NIH HHS/ -- R33 CA126674/CA/NCI NIH HHS/ -- R33 CA126674-03/CA/NCI NIH HHS/ -- Howard Hughes Medical Institute/ -- England -- Nature. 2011 Feb 10;470(7333):214-20. doi: 10.1038/nature09744.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉The Broad Institute of Harvard and MIT, Cambridge, Massachusetts 02142, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/21307934" target="_blank"〉PubMed〈/a〉

    A soybean cyst nematode resistance gene points to a new mechanism of plant resistance to pathogens (2012)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2012-12-14
    Description: Soybean (Glycine max (L.) Merr.) is an important crop that provides a sustainable source of protein and oil worldwide. Soybean cyst nematode (Heterodera glycines Ichinohe) is a microscopic roundworm that feeds on the roots of soybean and is a major constraint to soybean production. This nematode causes more than US$1 billion in yield losses annually in the United States alone, making it the most economically important pathogen on soybean. Although planting of resistant cultivars forms the core management strategy for this pathogen, nothing is known about the nature of resistance. Moreover, the increase in virulent populations of this parasite on most known resistance sources necessitates the development of novel approaches for control. Here we report the map-based cloning of a gene at the Rhg4 (for resistance to Heterodera glycines 4) locus, a major quantitative trait locus contributing to resistance to this pathogen. Mutation analysis, gene silencing and transgenic complementation confirm that the gene confers resistance. The gene encodes a serine hydroxymethyltransferase, an enzyme that is ubiquitous in nature and structurally conserved across kingdoms. The enzyme is responsible for interconversion of serine and glycine and is essential for cellular one-carbon metabolism. Alleles of Rhg4 conferring resistance or susceptibility differ by two genetic polymorphisms that alter a key regulatory property of the enzyme. Our discovery reveals an unprecedented plant resistance mechanism against a pathogen. The mechanistic knowledge of the resistance gene can be readily exploited to improve nematode resistance of soybean, an increasingly important global crop.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Liu, Shiming -- Kandoth, Pramod K -- Warren, Samantha D -- Yeckel, Greg -- Heinz, Robert -- Alden, John -- Yang, Chunling -- Jamai, Aziz -- El-Mellouki, Tarik -- Juvale, Parijat S -- Hill, John -- Baum, Thomas J -- Cianzio, Silvia -- Whitham, Steven A -- Korkin, Dmitry -- Mitchum, Melissa G -- Meksem, Khalid -- England -- Nature. 2012 Dec 13;492(7428):256-60. doi: 10.1038/nature11651.

    The genetic basis of early T-cell precursor acute lymphoblastic leukaemia (2012)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2012-01-13
    Description: Early T-cell precursor acute lymphoblastic leukaemia (ETP ALL) is an aggressive malignancy of unknown genetic basis. We performed whole-genome sequencing of 12 ETP ALL cases and assessed the frequency of the identified somatic mutations in 94 T-cell acute lymphoblastic leukaemia cases. ETP ALL was characterized by activating mutations in genes regulating cytokine receptor and RAS signalling (67% of cases; NRAS, KRAS, FLT3, IL7R, JAK3, JAK1, SH2B3 and BRAF), inactivating lesions disrupting haematopoietic development (58%; GATA3, ETV6, RUNX1, IKZF1 and EP300) and histone-modifying genes (48%; EZH2, EED, SUZ12, SETD2 and EP300). We also identified new targets of recurrent mutation including DNM2, ECT2L and RELN. The mutational spectrum is similar to myeloid tumours, and moreover, the global transcriptional profile of ETP ALL was similar to that of normal and myeloid leukaemia haematopoietic stem cells. These findings suggest that addition of myeloid-directed therapies might improve the poor outcome of ETP ALL.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3267575/" 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/PMC3267575/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Zhang, Jinghui -- Ding, Li -- Holmfeldt, Linda -- Wu, Gang -- Heatley, Sue L -- Payne-Turner, Debbie -- Easton, John -- Chen, Xiang -- Wang, Jianmin -- Rusch, Michael -- Lu, Charles -- Chen, Shann-Ching -- Wei, Lei -- Collins-Underwood, J Racquel -- Ma, Jing -- Roberts, Kathryn G -- Pounds, Stanley B -- Ulyanov, Anatoly -- Becksfort, Jared -- Gupta, Pankaj -- Huether, Robert -- Kriwacki, Richard W -- Parker, Matthew -- McGoldrick, Daniel J -- Zhao, David -- Alford, Daniel -- Espy, Stephen -- Bobba, Kiran Chand -- Song, Guangchun -- Pei, Deqing -- Cheng, Cheng -- Roberts, Stefan -- Barbato, Michael I -- Campana, Dario -- Coustan-Smith, Elaine -- Shurtleff, Sheila A -- Raimondi, Susana C -- Kleppe, Maria -- Cools, Jan -- Shimano, Kristin A -- Hermiston, Michelle L -- Doulatov, Sergei -- Eppert, Kolja -- Laurenti, Elisa -- Notta, Faiyaz -- Dick, John E -- Basso, Giuseppe -- Hunger, Stephen P -- Loh, Mignon L -- Devidas, Meenakshi -- Wood, Brent -- Winter, Stuart -- Dunsmore, Kimberley P -- Fulton, Robert S -- Fulton, Lucinda L -- Hong, Xin -- Harris, Christopher C -- Dooling, David J -- Ochoa, Kerri -- Johnson, Kimberly J -- Obenauer, John C -- Evans, William E -- Pui, Ching-Hon -- Naeve, Clayton W -- Ley, Timothy J -- Mardis, Elaine R -- Wilson, Richard K -- Downing, James R -- Mullighan, Charles G -- CA114766/CA/NCI NIH HHS/ -- CA98413/CA/NCI NIH HHS/ -- CA98543/CA/NCI NIH HHS/ -- P30 CA021765/CA/NCI NIH HHS/ -- P30 CA021765-33/CA/NCI NIH HHS/ -- P30CA021765/CA/NCI NIH HHS/ -- U01GM92666/GM/NIGMS NIH HHS/ -- U54 HG003079/HG/NHGRI NIH HHS/ -- England -- Nature. 2012 Jan 11;481(7380):157-63. doi: 10.1038/nature10725.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Computational Biology and Bioinformatics, St Jude Children's Research Hospital, Memphis, Tennessee 38105, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22237106" target="_blank"〉PubMed〈/a〉

    Single-cell Hi-C reveals cell-to-cell variability in chromosome structure (2013)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2013-09-27
    Description: Large-scale chromosome structure and spatial nuclear arrangement have been linked to control of gene expression and DNA replication and repair. Genomic techniques based on chromosome conformation capture (3C) assess contacts for millions of loci simultaneously, but do so by averaging chromosome conformations from millions of nuclei. Here we introduce single-cell Hi-C, combined with genome-wide statistical analysis and structural modelling of single-copy X chromosomes, to show that individual chromosomes maintain domain organization at the megabase scale, but show variable cell-to-cell chromosome structures at larger scales. Despite this structural stochasticity, localization of active gene domains to boundaries of chromosome territories is a hallmark of chromosomal conformation. Single-cell Hi-C data bridge current gaps between genomics and microscopy studies of chromosomes, demonstrating how modular organization underlies dynamic chromosome structure, and how this structure is probabilistically linked with genome activity patterns.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3869051/" 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/PMC3869051/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Nagano, Takashi -- Lubling, Yaniv -- Stevens, Tim J -- Schoenfelder, Stefan -- Yaffe, Eitan -- Dean, Wendy -- Laue, Ernest D -- Tanay, Amos -- Fraser, Peter -- BBS/E/B/0000M241/Biotechnology and Biological Sciences Research Council/United Kingdom -- BBS/E/B/000C0404/Biotechnology and Biological Sciences Research Council/United Kingdom -- G0800036/Medical Research Council/United Kingdom -- G117/530/Medical Research Council/United Kingdom -- Wellcome Trust/United Kingdom -- Medical Research Council/United Kingdom -- Biotechnology and Biological Sciences Research Council/United Kingdom -- England -- Nature. 2013 Oct 3;502(7469):59-64. doi: 10.1038/nature12593.

    De novo mutations in epileptic encephalopathies (2013)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2013-08-13
    Description: Epileptic encephalopathies are a devastating group of severe childhood epilepsy disorders for which the cause is often unknown. Here we report a screen for de novo mutations in patients with two classical epileptic encephalopathies: infantile spasms (n = 149) and Lennox-Gastaut syndrome (n = 115). We sequenced the exomes of 264 probands, and their parents, and confirmed 329 de novo mutations. A likelihood analysis showed a significant excess of de novo mutations in the approximately 4,000 genes that are the most intolerant to functional genetic variation in the human population (P = 2.9 x 10(-3)). Among these are GABRB3, with de novo mutations in four patients, and ALG13, with the same de novo mutation in two patients; both genes show clear statistical evidence of association with epileptic encephalopathy. Given the relevant site-specific mutation rates, the probabilities of these outcomes occurring by chance are P = 4.1 x 10(-10) and P = 7.8 x 10(-12), respectively. Other genes with de novo mutations in this cohort include CACNA1A, CHD2, FLNA, GABRA1, GRIN1, GRIN2B, HNRNPU, IQSEC2, MTOR and NEDD4L. Finally, we show that the de novo mutations observed are enriched in specific gene sets including genes regulated by the fragile X protein (P 〈 10(-8)), as has been reported previously for autism spectrum disorders.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3773011/" 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/PMC3773011/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Epi4K Consortium -- Epilepsy Phenome/Genome Project -- Allen, Andrew S -- Berkovic, Samuel F -- Cossette, Patrick -- Delanty, Norman -- Dlugos, Dennis -- Eichler, Evan E -- Epstein, Michael P -- Glauser, Tracy -- Goldstein, David B -- Han, Yujun -- Heinzen, Erin L -- Hitomi, Yuki -- Howell, Katherine B -- Johnson, Michael R -- Kuzniecky, Ruben -- Lowenstein, Daniel H -- Lu, Yi-Fan -- Madou, Maura R Z -- Marson, Anthony G -- Mefford, Heather C -- Esmaeeli Nieh, Sahar -- O'Brien, Terence J -- Ottman, Ruth -- Petrovski, Slave -- Poduri, Annapurna -- Ruzzo, Elizabeth K -- Scheffer, Ingrid E -- Sherr, Elliott H -- Yuskaitis, Christopher J -- Abou-Khalil, Bassel -- Alldredge, Brian K -- Bautista, Jocelyn F -- Boro, Alex -- Cascino, Gregory D -- Consalvo, Damian -- Crumrine, Patricia -- Devinsky, Orrin -- Fiol, Miguel -- Fountain, Nathan B -- French, Jacqueline -- Friedman, Daniel -- Geller, Eric B -- Glynn, Simon -- Haut, Sheryl R -- Hayward, Jean -- Helmers, Sandra L -- Joshi, Sucheta -- Kanner, Andres -- Kirsch, Heidi E -- Knowlton, Robert C -- Kossoff, Eric H -- Kuperman, Rachel -- McGuire, Shannon M -- Motika, Paul V -- Novotny, Edward J -- Paolicchi, Juliann M -- Parent, Jack M -- Park, Kristen -- Shellhaas, Renee A -- Shih, Jerry J -- Singh, Rani -- Sirven, Joseph -- Smith, Michael C -- Sullivan, Joseph -- Lin Thio, Liu -- Venkat, Anu -- Vining, Eileen P G -- Von Allmen, Gretchen K -- Weisenberg, Judith L -- Widdess-Walsh, Peter -- Winawer, Melodie R -- 1RC2NS070342/NS/NINDS NIH HHS/ -- NS053998/NS/NINDS NIH HHS/ -- NS077274/NS/NINDS NIH HHS/ -- NS077276/NS/NINDS NIH HHS/ -- NS077303/NS/NINDS NIH HHS/ -- NS077364/NS/NINDS NIH HHS/ -- R56AI098588/AI/NIAID NIH HHS/ -- U01 NS053998/NS/NINDS NIH HHS/ -- U01 NS077274/NS/NINDS NIH HHS/ -- U01 NS077276/NS/NINDS NIH HHS/ -- U01 NS077303/NS/NINDS NIH HHS/ -- U01 NS077364/NS/NINDS NIH HHS/ -- U01AI067854/AI/NIAID NIH HHS/ -- UL1 TR000005/TR/NCATS NIH HHS/ -- England -- Nature. 2013 Sep 12;501(7466):217-21. doi: 10.1038/nature12439.
