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.

Description: Autism spectrum disorders (ASDs) are childhood neurodevelopmental disorders with complex genetic origins. Previous studies focusing on candidate genes or genomic regions have identified several copy number variations (CNVs) that are associated with an increased risk of ASDs. Here we present the results from a whole-genome CNV study on a cohort of 859 ASD cases and 1,409 healthy children of European ancestry who were genotyped with approximately 550,000 single nucleotide polymorphism markers, in an attempt to comprehensively identify CNVs conferring susceptibility to ASDs. Positive findings were evaluated in an independent cohort of 1,336 ASD cases and 1,110 controls of European ancestry. Besides previously reported ASD candidate genes, such as NRXN1 (ref. 10) and CNTN4 (refs 11, 12), several new susceptibility genes encoding neuronal cell-adhesion molecules, including NLGN1 and ASTN2, were enriched with CNVs in ASD cases compared to controls (P = 9.5 x 10(-3)). Furthermore, CNVs within or surrounding genes involved in the ubiquitin pathways, including UBE3A, PARK2, RFWD2 and FBXO40, were affected by CNVs not observed in controls (P = 3.3 x 10(-3)). We also identified duplications 55 kilobases upstream of complementary DNA AK123120 (P = 3.6 x 10(-6)). Although these variants may be individually rare, they target genes involved in neuronal cell-adhesion or ubiquitin degradation, indicating that these two important gene networks expressed within the central nervous system may contribute to the genetic susceptibility of ASD.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2925224/" target="_blank"〉〈img

Description: Multiple sclerosis is a common disease of the central nervous system in which the interplay between inflammatory and neurodegenerative processes typically results in intermittent neurological disturbance followed by progressive accumulation of disability. Epidemiological studies have shown that genetic factors are primarily responsible for the substantially increased frequency of the disease seen in the relatives of affected individuals, and systematic attempts to identify linkage in multiplex families have confirmed that variation within the major histocompatibility complex (MHC) exerts the greatest individual effect on risk. Modestly powered genome-wide association studies (GWAS) have enabled more than 20 additional risk loci to be identified and have shown that multiple variants exerting modest individual effects have a key role in disease susceptibility. Most of the genetic architecture underlying susceptibility to the disease remains to be defined and is anticipated to require the analysis of sample sizes that are beyond the numbers currently available to individual research groups. In a collaborative GWAS involving 9,772 cases of European descent collected by 23 research groups working in 15 different countries, we have replicated almost all of the previously suggested associations and identified at least a further 29 novel susceptibility loci. Within the MHC we have refined the identity of the HLA-DRB1 risk alleles and confirmed that variation in the HLA-A gene underlies the independent protective effect attributable to the class I region. Immunologically relevant genes are significantly overrepresented among those mapping close to the identified loci and particularly implicate T-helper-cell differentiation in the pathogenesis of multiple sclerosis.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3182531/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009"

Description: Hematological traits are important clinical indicators, the genetic determinants of which have not been fully investigated. Common measures of hematological traits include red blood cell (RBC) count, hemoglobin concentration (HGB), hematocrit (HCT), mean corpuscular hemoglobin (MCH), MCH concentration (MCHC), mean corpuscular volume (MCV), platelet count (PLT) and white blood cell (WBC) count. We carried out a genome-wide association study of the eight common hematological traits among 7943 African-American children and 6234 Caucasian children. In African Americans, we report five novel associations of HBE1 variants with HCT and MCHC, the alpha-globin gene cluster variants with RBC and MCHC, and a variant at the ARHGEF3 locus with PLT, as well as replication of four previously reported loci at genome-wide significance. In Caucasians, we report a novel association of variants at the COPZ1 locus with PLT as well as replication of four previously reported loci at genome-wide significance. Extended analysis of an association observed between MCH and the alpha-globin gene cluster variants demonstrated independent effects and epistatic interaction at the locus, impacting the risk of iron deficiency anemia in African Americans with specific genotype states. In summary, we extend the understanding of genetic variants underlying hematological traits based on analyses in African-American children.

Description: Laboratory red blood cell (RBC) measurements are clinically important, heritable and differ among ethnic groups. To identify genetic variants that contribute to RBC phenotypes in African Americans (AAs), we conducted a genome-wide association study in up to ~16 500 AAs. The alpha-globin locus on chromosome 16pter [lead SNP rs13335629 in ITFG3 gene; P 〈 1E–13 for hemoglobin (Hgb), RBC count, mean corpuscular volume (MCV), MCH and MCHC] and the G6PD locus on Xq28 [lead SNP rs1050828; P 〈 1E – 13 for Hgb, hematocrit (Hct), MCV, RBC count and red cell distribution width (RDW)] were each associated with multiple RBC traits. At the alpha-globin region, both the common African 3.7 kb deletion and common single nucleotide polymorphisms (SNPs) appear to contribute independently to RBC phenotypes among AAs. In the 2p21 region, we identified a novel variant of PRKCE distinctly associated with Hct in AAs. In a genome-wide admixture mapping scan, local European ancestry at the 6p22 region containing HFE and LRRC16A was associated with higher Hgb. LRRC16A has been previously associated with the platelet count and mean platelet volume in AAs, but not with Hgb. Finally, we extended to AAs the findings of association of erythrocyte traits with several loci previously reported in Europeans and/or Asians, including CD164 and HBS1L-MYB . In summary, this large-scale genome-wide analysis in AAs has extended the importance of several RBC-associated genetic loci to AAs and identified allelic heterogeneity and pleiotropy at several previously known genetic loci associated with blood cell traits in AAs.
