Abstract

Autism spectrum disorder (ASD) is a highly heritable disorder of complex and heterogeneous aetiology. It is primarily characterized by altered cognitive ability including impaired language and communication skills and fundamental deficits in social reciprocity. Despite some notable successes in neuropsychiatric genetics, overall, the high heritability of ASD (90%) remains poorly explained by common genetic risk variants. However, recent studies suggest that rare genomic variation, in particular copy number variation, may account for a significant proportion of the genetic basis of ASD. We present a large scale analysis to identify candidate genes which may contain low-frequency recessive variation contributing to ASD while taking into account the potential contribution of population differences to the genetic heterogeneity of ASD. Our strategy, homozygous haplotype (HH) mapping, aims to detect homozygous segments of identical haplotype structure that are shared at a higher frequency amongst ASD patients compared to parental controls. The analysis was performed on 1,402 Autism Genome Project trios genotyped for 1 million single nucleotide polymorphisms (SNPs). We identified 25 known and 1,218 novel ASD candidate genes in the discovery analysis including CADM2, ABHD14A, CHRFAM7A, GRIK2, GRM3, EPHA3, FGF10, KCND2, PDZK1, IMMP2L and FOXP2. Furthermore, 10 of the previously reported ASD genes and 300 of the novel candidates identified in the discovery analysis were replicated in an independent sample of 1,182 trios. Our results demonstrate that regions of HH are significantly enriched for previously reported ASD candidate genes and the observed association is independent of gene size (odds ratio 2.10). Our findings highlight the applicability of HH mapping in complex disorders such as ASD and offer an alternative approach to the analysis of genome-wide association data. © The Author(s) 2011.

Abstract

Recent genome-wide association studies (GWAS) have implicated a range of genes from discrete biological pathways in the aetiology of autism. However, despite the strong influence of genetic factors, association studies have yet to identify statistically robust, replicated major effect genes or SNPs. We apply the principle of the SNP ratio test methodology described by O'Dushlaine et al to over 2100 families from the Autism Genome Project (AGP). Using a two-stage design we examine association enrichment in 5955 unique gene-ontology classifications across four groupings based on two phenotypic and two ancestral classifications. Based on estimates from simulation we identify excess of association enrichment across all analyses. We observe enrichment in association for sets of genes involved in diverse biological processes, including pyruvate metabolism, transcription factor activation, cell-signalling and cell-cycle regulation. Both genes and processes that show enrichment have previously been examined in autistic disorders and offer biologically plausibility to these findings.

Abstract

Although autism spectrum disorders (ASDs) have a substantial genetic basis, most of the known genetic risk has been traced to rare variants, principally copy number variants (CNVs). To identify common risk variation, the Autism Genome Project (AGP) Consortium genotyped 1558 rigorously defined ASD families for 1 million single-nucleotide polymorphisms (SNPs) and analyzed these SNP genotypes for association with ASD. In one of four primary association analyses, the association signal for marker rs4141463, located within MACROD2, crossed the genome-wide association significance threshold of P < 5 3 10-28. When a smaller replication sample was analyzed, the risk allele at rs4141463 was again over-transmitted; yet, consistent with the winner's curse, its effect size in the replication sample was much smaller; and, for the combined samples, the association signal barely fell below the P < 5 × 10-28 threshold. Exploratory analyses of phenotypic subtypes yielded no significant associations after correction for multiple testing. They did, however, yield strong signals within several genes, KIAA0564, PLD5, POU6F2, ST8SIA2 and TAF1C. © The Author 2010. Published by Oxford University Press. All rights reserved.

Abstract

While it is apparent that rare variation can play an important role in the genetic architecture of autism spectrum disorders (ASDs), the contribution of common variation to the risk of developing ASD is less clear. To produce a more comprehensive picture, we report Stage 2 of the Autism Genome Project genome-wide association study, adding 1301 ASD families and bringing the total to 2705 families analysed (Stages 1 and 2). In addition to evaluating the association of individual single nucleotide polymorphisms (SNPs), we also sought evidence that common variants, en masse, might affect the risk. Despite genotyping over a million SNPs covering the genome, no single SNP shows significant association with ASD or selected phenotypes at a genome-wide level. The SNP that achieves the smallest P-value from secondary analyses is rs1718101. It falls in CNTNAP2, a gene previously implicated in susceptibility for ASD. This SNP also shows modest association with age of word/phrase acquisition in ASD subjects, of interest because features of language development are also associated with other variation in CNTNAP2. In contrast, allele scores derived from the transmission of common alleles to Stage 1 cases significantly predict case status in the independent Stage 2 sample. Despite being significant, the variance explained by these allele scores was small (Vm < 1%). Based on results from individual SNPs and their en masse effect on risk, as inferred from the allele score results, it is reasonable to conclude that common variants affect the risk for ASD but their individual effects are modest.

Abstract

International audience; While it is apparent that rare variation can play an important role in the genetic architecture of autism spectrum disorders (ASDs), the contribution of common variation to the risk of developing ASD is less clear. To produce a more comprehensive picture, we report Stage 2 of the Autism Genome Project genome-wide association study, adding 1301 ASD families and bringing the total to 2705 families analysed (Stages 1 and 2). In addition to evaluating the association of individual single nucleotide polymorphisms (SNPs), we also sought evidence that common variants, en masse, might affect the risk. Despite genotyping over a million SNPs covering the genome, no single SNP shows significant association with ASD or selected phenotypes at a genome-wide level. The SNP that achieves the smallest P-value from secondary analyses is rs1718101. It falls in CNTNAP2, a gene previously implicated in susceptibility for ASD. This SNP also shows modest association with age of word/phrase acquisition in ASD subjects, of interest because features of language development are also associated with other variation in CNTNAP2. In contrast, allele scores derived from the transmission of common alleles to Stage 1 cases significantly predict case status in the independent Stage 2 sample. Despite being significant, the variance explained by these allele scores was small (Vm< 1%). Based on results from individual SNPs and their en masse effect on risk, as inferred from the allele score results, it is reasonable to conclude that common variants affect the risk for ASD but their individual effects are modest.

Abstract

Although autism spectrum disorders (ASDs) have a substantial genetic basis, most of the known genetic risk has been traced to rare variants, principally copy number variants (CNVs). To identify common risk variation, the Autism Genome Project (AGP) Consortium genotyped 1558 rigorously defined ASD families for 1 million single-nucleotide polymorphisms (SNPs) and analyzed these SNP genotypes for association with ASD. In one of four primary association analyses, the association signal for marker rs4141463, located within MACROD2, crossed the genome-wide association significance threshold of P < 5 × 10−8. When a smaller replication sample was analyzed, the risk allele at rs4141463 was again over-transmitted; yet, consistent with the winner's curse, its effect size in the replication sample was much smaller; and, for the combined samples, the association signal barely fell below the P < 5 × 10−8 threshold. Exploratory analyses of phenotypic subtypes yielded no significant associations after correction for multiple testing. They did, however, yield strong signals within several genes, KIAA0564, PLD5, POU6F2, ST8SIA2 and TAF1C.

Abstract

Purpose. –To describe different longitudinal profiles in communicative abilities and symptoms severity in early autism.Methods. –Five children with autism, aged from 3;3 to 4;10 years at baseline, were tested for production and comprehension of imperative and declarative pointing at about 4-month intervals. Concurrently with these sessions, children were evaluated in terms of cognitive and communicative abilities, and symptoms severity.Results. –Four subjects showed a mild to severe retardation in communicative and linguistic abilities. For production, all children exhibited the imperative pointing and only one the declarative pointing. For comprehension, two subjects showed the same profile as in production (‘only imperative’ and ‘first imperative–later declarative’, respectively). One child did not show any clear comprehension of the pointing gestures produced by the experimenter, and one child was able to understand both pointing in the same session. Childhood autism rating scale (CARS) global scores tended to decrease across sessions for all subjects and different individual profiles were identified.Discussion. –Declarative or experience-sharing pointing emerged later in one child only; it remained absent in four children as production, and in two children as comprehension. A preliminary conclusion based on CARS rating, is that autism involves a symptomatology that may decrease across time even if children differ in the decreasing profile relative to specific scores.

Abstract

Autism spectrum disorder (ASD) is a highly heritable disorder of complex and heterogeneous aetiology. It is primarily characterized by altered cognitive ability including impaired language and communication skills and fundamental deficits in social reciprocity. Despite some notable successes in neuropsychiatric genetics, overall, the high heritability of ASD (~90%) remains poorly explained by common genetic risk variants. However, recent studies suggest that rare genomic variation, in particular copy number variation, may account for a significant proportion of the genetic basis of ASD. We present a large scale analysis to identify candidate genes which may contain low-frequency recessive variation contributing to ASD while taking into account the potential contribution of population differences to the genetic heterogeneity of ASD. Our strategy, homozygous haplotype (HH) mapping, aims to detect homozygous segments of identical haplotype structure that are shared at a higher frequency amongst ASD patients compared to parental controls. The analysis was performed on 1,402 Autism Genome Project trios genotyped for 1 million single nucleotide polymorphisms (SNPs). We identified 25 known and 1,218 novel ASD candidate genes in the discovery analysis including CADM2, ABHD14A, CHRFAM7A, GRIK2, GRM3, EPHA3, FGF10, KCND2, PDZK1, IMMP2L and FOXP2. Furthermore, 10 of the previously reported ASD genes and 300 of the novel candidates identified in the discovery analysis were replicated in an independent sample of 1,182 trios. Our results demonstrate that regions of HH are significantly enriched for previously reported ASD candidate genes and the observed association is independent of gene size (odds ratio 2.10). Our findings highlight the applicability of HH mapping in complex disorders such as ASD and offer an alternative approach to the analysis of genome-wide association data.

Abstract

While it is apparent that rare variation can play an important role in the genetic architecture of autism spectrum disorders (ASDs), the contribution of common variation to the risk of developing ASD is less clear. To produce a more comprehensive picture, we report Stage 2 of the Autism Genome Project genome-wide association study, adding 1301 ASD families and bringing the total to 2705 families analysed (Stages 1 and 2). In addition to evaluating the association of individual single nucleotide polymorphisms (SNPs), we also sought evidence that common variants, en masse, might affect the risk. Despite genotyping over a million SNPs covering the genome, no single SNP shows significant association with ASD or selected phenotypes at a genome-wide level. The SNP that achieves the smallest P-value from secondary analyses is rs1718101. It falls in CNTNAP2, a gene previously implicated in susceptibility for ASD. This SNP also shows modest association with age of word/phrase acquisition in ASD subjects, of interest because features of language development are also associated with other variation in CNTNAP2. In contrast, allele scores derived from the transmission of common alleles to Stage 1 cases significantly predict case status in the independent Stage 2 sample. Despite being significant, the variance explained by these allele scores was small (Vm< 1%). Based on results from individual SNPs and their en masse effect on risk, as inferred from the allele score results, it is reasonable to conclude that common variants affect the risk for ASD but their individual effects are modest.

Abstract

Idic(15) syndrome is a neurogenetic disorder clinically delineated by early central hypotonia, developmental delay and intellectual disability (ID), epilepsy, absent or very poor speech, and autistic or autistic-like behavior. It is due to the presence of a supernumerary marker chromosome formed by the inverted duplication of proximal chromosome 15, resulting in tetrasomy 15p and partial tetrasomy 15q, and containing the Prader-Willi/Angelman syndrome critical region (PWS/ASCR). The vast majority of these idic(15) derives from the two homologous maternal chromosomes at meiosis. To better define the behavior profile, we studied 22 idic(15) children (15 males and 7 females) observed at our institute between 1986 and 2010, and present, in detail, case studies of five of them. We have been able to perform standardized and semi-standardized measures of intelligence, and psychopathology in only 13 of our 22 patients, due to the limitations of chronological age, and to the severity of ID (ranging from mild-moderate, in 15%, to severe-profound, in 85% of our sample). The results show a distinct developmental profile in idic(15) patients, that may provide a behavioral signature for autism spectrum disorder (ASD)/ASD-like arising from the susceptibility locus on proximal 15q; and suggest that idic(15) individuals are not "true autistic," but distinct "autistic-like" persons with high score in the third ADOS-G and ADI-R area., (© 2010 Wiley-Liss, Inc.)

Abstract

The autism spectrum disorders (ASDs) are a group of conditions characterized by impairments in reciprocal social interaction and communication, and the presence of restricted and repetitive behaviours. Individuals with an ASD vary greatly in cognitive development, which can range from above average to intellectual disability. Although ASDs are known to be highly heritable ( approximately 90%), the underlying genetic determinants are still largely unknown. Here we analysed the genome-wide characteristics of rare (<1% frequency) copy number variation in ASD using dense genotyping arrays. When comparing 996 ASD individuals of European ancestry to 1,287 matched controls, cases were found to carry a higher global burden of rare, genic copy number variants (CNVs) (1.19 fold, P = 0.012), especially so for loci previously implicated in either ASD and/or intellectual disability (1.69 fold, P = 3.4 x 10(-4)). Among the CNVs there were numerous de novo and inherited events, sometimes in combination in a given family, implicating many novel ASD genes such as SHANK2, SYNGAP1, DLGAP2 and the X-linked DDX53-PTCHD1 locus. We also discovered an enrichment of CNVs disrupting functional gene sets involved in cellular proliferation, projection and motility, and GTPase/Ras signalling. Our results reveal many new genetic and functional targets in ASD that may lead to final connected pathways.

Abstract

Using aCGH, we have identified a pericentromeric deletion, spanning about 8.2 Mb, within 16p11.2-p12.2 in a patient with developmental delay (DD) and dysmorphic features. This deletion arose de novo and is flanked by segmental duplications. The proposita was the only child of healthy nonconsanguineous parents, born after an uneventful pregnancy, at 40 weeks gestation, by normal delivery. She was referred to us at age 3 10/12 years for evaluation of DD and absent speech. On examination, there were a flat face; low-set, posteriorly rotated ears; high-arched palate; hypotonic face; right single palmar crease; long, thin fingers; and a sacral dimple. Her height was at the 50th centile, weight at the 25th, and OFC at the 30th. Results of DNA FraX, HRB chromosomes, metabolic work-up, audiologic evaluation, brain MRI, electroencephalogram, and heart/abdomen ultrasonography were normal. When last seen, aged 8 years, she had a moderate intellectual disability (ID) and poor speech. She was hyperactive with short attention span and difficulty in concentration, but, based on formal testing, did not have autism. Our patient shows common clinical features to the four individuals described by Ballif et al. [Ballif et al. (2007); Nat Genet 39:1071-1073], and further characterizes the new microdeletion syndrome of 16p11.2-p12.2. aCGH suggests that the deletions of all cases share the same distal breakpoint. Of note, the proximal breakpoint of our proposita overlaps the distal breakpoint of the autistic patients studied by Kumar et al. [Kumar et al. (2008); Hum Mol Genet 17:628-638] and Weiss et al. [Weiss et al. (2008); N Eng J Med 358:667-675], confirming that the 16p region carrying susceptibility to autism is more centromeric. Our observation further defines two different, contiguous 16p genomic regions, responsible for a distinct MCA/ID syndrome, and for autism, respectively., ((c) 2009 Wiley-Liss, Inc.)

Abstract

As a subset of genetic abnormalities, subtelomeric deletions have been found in 7-10% of individuals with mental retardation (MR). One subtelomeric deletion, Wolf-Hirschhorn syndrome (WHS), causes mild to severe MR, but the cognitive-behavioral features of individuals with WHS have not been studied systematically. To that end, we administered a comprehensive cognitive-behavioral battery to 12 children with WHS, ages 4-17 years, who also had some expressive language. Using the Stanford-Binet (4th Edition), we found cognitive deficits ranged from mild to severe, with mean IQ = 44.1. Interviewing parents with the Vineland Adaptive Behavior Scales, we found mean adaptive behavior score (DQ) = 37.3, with females exhibiting slightly higher scores than males. Cognitive profiles indicated relative strengths in Verbal and Quantitative Reasoning. Adaptive behavior profiles noted significant relative strengths in the Socialization Domain. These cognitive-behavioral profiles differed from children with other subtelomeric deletion syndromes, 2q37 or 8p23. Attention deficits and hyperactivity (ADHD) were observed in 7/12 (58%) of the children we tested. One child attained a score on the Child Autism Rating Scale (CARS) suggestive of mild autism. We conclude that different genetic disorders, which cause MR, produce diverse cognitive-behavioral profiles. Consequently, cognitive-behavioral profiles of children with MR need to be assessed more comprehensively.

Abstract

This study analyses the possible risk factors for the on-set of behavioural disorders and psychiatric disturbances in a group of 30 early-treated congenital hypothyroidism (CH) subjects (12 children and 18 adolescents) compared with a control group of 116 age-matched normal subjects (58 children and 58 adolescents). The study also allowed us to evaluate the possible age at onset of behavioural disorders. Both the sample's and the controls' behaviours were assessed using a specific diagnostic instrument: Achenbach's and Edelbrock's Child Behaviour Checklist (CBCL). A clinical structured interview, the Diagnostic Interview for Children and Adolescents--Revised (DICA-R) was also administered to 18 adolescents with early-treated CH, in order to determine the presence of psychopathological disturbances. In accordance with literature data, the children and adolescents with early-treated CH showed more behavioural problems than age-matched, normal controls. In the children, a statistically significant difference versus the controls emerged only in their higher delinquent behaviour score, while the adolescents gave, on the CBCL, significantly higher scores compared with controls in the withdrawal, anxiety/depression, thought problems, attention problems and aggressive behaviour scales. In the DICA-R, 44% of adolescents with early-treated CH showed symptoms of anxiety disorder, in particular, separation anxiety disorder with phobic components; 16% showed mood disorder and depression and 11% showed behavioural disorders with attention deficit.
