    Description: Autism spectrum disorders (ASDs) represent a group of childhood neurodevelopmental and neuropsychiatric disorders characterized by deficits in verbal communication, impairment of social interaction, and restricted and repetitive patterns of interests and behaviour. To identify common genetic risk factors underlying ASDs, here we present the results of genome-wide association studies on a cohort of 780 families (3,101 subjects) with affected children, and a second cohort of 1,204 affected subjects and 6,491 control subjects, all of whom were of European ancestry. Six single nucleotide polymorphisms between cadherin 10 (CDH10) and cadherin 9 (CDH9)-two genes encoding neuronal cell-adhesion molecules-revealed strong association signals, with the most significant SNP being rs4307059 (P = 3.4 x 10(-8), odds ratio = 1.19). These signals were replicated in two independent cohorts, with combined P values ranging from 7.4 x 10(-8) to 2.1 x 10(-10). Our results implicate neuronal cell-adhesion molecules in the pathogenesis of ASDs, and represent, to our knowledge, the first demonstration of genome-wide significant association of common variants with susceptibility to ASDs.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2943511/" 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/PMC2943511/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wang, Kai -- Zhang, Haitao -- Ma, Deqiong -- Bucan, Maja -- Glessner, Joseph T -- Abrahams, Brett S -- Salyakina, Daria -- Imielinski, Marcin -- Bradfield, Jonathan P -- Sleiman, Patrick M A -- Kim, Cecilia E -- Hou, Cuiping -- Frackelton, Edward -- Chiavacci, Rosetta -- Takahashi, Nagahide -- Sakurai, Takeshi -- Rappaport, Eric -- Lajonchere, Clara M -- Munson, Jeffrey -- Estes, Annette -- Korvatska, Olena -- Piven, Joseph -- Sonnenblick, Lisa I -- Alvarez Retuerto, Ana I -- Herman, Edward I -- Dong, Hongmei -- Hutman, Ted -- Sigman, Marian -- Ozonoff, Sally -- Klin, Ami -- Owley, Thomas -- Sweeney, John A -- Brune, Camille W -- Cantor, Rita M -- Bernier, Raphael -- Gilbert, John R -- Cuccaro, Michael L -- McMahon, William M -- Miller, Judith -- State, Matthew W -- Wassink, Thomas H -- Coon, Hilary -- Levy, Susan E -- Schultz, Robert T -- Nurnberger, John I -- Haines, Jonathan L -- Sutcliffe, James S -- Cook, Edwin H -- Minshew, Nancy J -- Buxbaum, Joseph D -- Dawson, Geraldine -- Grant, Struan F A -- Geschwind, Daniel H -- Pericak-Vance, Margaret A -- Schellenberg, Gerard D -- Hakonarson, Hakon -- 1U24MH081810/MH/NIMH NIH HHS/ -- HD055751/HD/NICHD NIH HHS/ -- HD055782-01/HD/NICHD NIH HHS/ -- HD055784/HD/NICHD NIH HHS/ -- M01-RR00064/RR/NCRR NIH HHS/ -- MH061009/MH/NIMH NIH HHS/ -- MH0666730/MH/NIMH NIH HHS/ -- MH080647/MH/NIMH NIH HHS/ -- MH081754/MH/NIMH NIH HHS/ -- MH64547/MH/NIMH NIH HHS/ -- MH69359/MH/NIMH NIH HHS/ -- N01-HD-4-3368/HD/NICHD NIH HHS/ -- N01-HD-4-3383/HD/NICHD NIH HHS/ -- NS049261/NS/NINDS NIH HHS/ -- NS26630/NS/NINDS NIH HHS/ -- NS36768/NS/NINDS NIH HHS/ -- P01 NS026630/NS/NINDS NIH HHS/ -- P01 NS026630-109001/NS/NINDS NIH HHS/ -- P50 HD055748/HD/NICHD NIH HHS/ -- P50 HD055751/HD/NICHD NIH HHS/ -- P50 HD055751-01/HD/NICHD NIH HHS/ -- P50 HD055782-01/HD/NICHD NIH HHS/ -- P50 HD055784/HD/NICHD NIH HHS/ -- P50 HD055784-01/HD/NICHD NIH HHS/ -- P50 HD055784-010002/HD/NICHD NIH HHS/ -- P50 HD055784-020002/HD/NICHD NIH HHS/ -- P50 HD055784-030002/HD/NICHD NIH HHS/ -- R01 MH061009/MH/NIMH NIH HHS/ -- R01 MH061009-01A1/MH/NIMH NIH HHS/ -- R01 MH064547/MH/NIMH NIH HHS/ -- R01 MH064547-01/MH/NIMH NIH HHS/ -- R01 MH064547-01S1/MH/NIMH NIH HHS/ -- R01 MH064547-02/MH/NIMH NIH HHS/ -- R01 MH064547-02S1/MH/NIMH NIH HHS/ -- R01 MH064547-03/MH/NIMH NIH HHS/ -- R01 MH064547-04/MH/NIMH NIH HHS/ -- R01 MH064547-05/MH/NIMH NIH HHS/ -- R01 MH069359/MH/NIMH NIH HHS/ -- R01 MH069359-01A2/MH/NIMH NIH HHS/ -- R01 MH080647/MH/NIMH NIH HHS/ -- R01 MH080647-11/MH/NIMH NIH HHS/ -- R01 MH081754/MH/NIMH NIH HHS/ -- R01 MH081754-01/MH/NIMH NIH HHS/ -- R01 MH081754-02/MH/NIMH NIH HHS/ -- R01 NS036768/NS/NINDS NIH HHS/ -- R01 NS036768-06/NS/NINDS NIH HHS/ -- R01 NS049261/NS/NINDS NIH HHS/ -- R01 NS049261-01A2/NS/NINDS NIH HHS/ -- U54 MH066673/MH/NIMH NIH HHS/ -- U54 MH066673-01A10001/MH/NIMH NIH HHS/ -- UL1 RR024134/RR/NCRR NIH HHS/ -- UL1 RR024134-01/RR/NCRR NIH HHS/ -- UL1-RR024134-03/RR/NCRR NIH HHS/ -- Medical Research Council/United Kingdom -- England -- Nature. 2009 May 28;459(7246):528-33. doi: 10.1038/nature07999.

    Evaluation of copy number variations reveals novel candidate genes in autism spectrum disorder-associated pathways (2012)
    Oxford University Press

    Description: Autism spectrum disorders (ASDs) are highly heritable, yet relatively few associated genetic loci have been replicated. Copy number variations (CNVs) have been implicated in autism; however, the majority of loci contribute to 〈1% of the disease population. Therefore, independent studies are important to refine associated CNV regions and discover novel susceptibility genes. In this study, a genome-wide SNP array was utilized for CNV detection by two distinct algorithms in a European ancestry case–control data set. We identify a significantly higher burden in the number and size of deletions, and disrupting more genes in ASD cases. Moreover, 18 deletions larger than 1 Mb were detected exclusively in cases, implicating novel regions at 2q22.1, 3p26.3, 4q12 and 14q23. Case-specific CNVs provided further evidence for pathways previously implicated in ASDs, revealing new candidate genes within the GABAergic signaling and neural development pathways. These include DBI , an allosteric binder of GABA receptors, GABARAPL1 , the GABA receptor-associated protein, and SLC6A11 , a postsynaptic GABA transporter. We also identified CNVs in COBL , deletions of which cause defects in neuronal cytoskeleton morphogenesis in model vertebrates, and DNER , a neuron-specific Notch ligand required for cerebellar development. Moreover, we found evidence of genetic overlap between ASDs and other neurodevelopmental and neuropsychiatric diseases. These genes include glutamate receptors ( GRID1 , GRIK2 and GRIK4 ), synaptic regulators ( NRXN3 , SLC6A8 and SYN3 ), transcription factor (ZNF804A) and RNA-binding protein FMR1 . Taken together, these CNVs may be a few of the missing pieces of ASD heritability and lead to discovering novel etiological mechanisms.
