A genetic overlap has been shown between ALTs and ASD, indicating that common variation in ASD candidate genes may also influence ALTs. In our study, we have investigated the SNP rs4307059 that has been associated with both ALTs and ASD. In addition, we genotyped polymorphisms in a selection of genes involved in synaptic functioning, that is, SHANK3, RELN, and CNTNAP2, which repeatedly have been associated with ASD. The possible associations of these polymorphisms with ALTs, as well as genetic factors for neurodevelopmental problems (NDPs), were investigated in a large cohort from the general population: The Child and Adolescent Twin Study in Sweden. For analyses of ALTs and NDPs, 12,319 subjects (including 2,268 monozygotic (MZ) and 3,805 dizygotic (DZ) twin pairs) and 8,671 subjects (including 2,243 MZ and 2,044 DZ twin pairs), respectively, were included in the analyses.

Autism spectrum disorders and coexisting disorders in a nationwide Swedish twin study / Sebastian LUNDSTROM in Journal of Child Psychology and Psychiatry, 56-6 (June 2015)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 56-6 (June 2015) . - p.702-710 Titre : Autism spectrum disorders and coexisting disorders in a nationwide Swedish twin study Type de document : Texte imprimé et/ou numérique Auteurs : Sebastian LUNDSTROM, Auteur ; Abraham REICHENBERG, Auteur ; Jonas MELKE, Auteur ; Maria RASTAM, Auteur ; Nora KEREKES, Auteur ; Paul LICHTENSTEIN, Auteur ; Christopher GILLBERG, Auteur ; Henrik ANCKARSATER, Auteur Article en page(s) : p.702-710 Langues : Anglais (eng) Mots-clés : Autism spectrum disorders  comorbidity  genetics  twins Index. décimale : PER Périodiques Résumé : Background Evidence from twin and molecular genetic studies is accumulating that Autism Spectrum Disorder (ASD) shares substantial etiological factors with other disorders. This is mirrored in clinical practice where ASD without coexisting disorders is rare. The present study aims to examine the range of coexisting disorders in ASD in a genetically informative cohort. Methods Parents of all Swedish 9-year-old twins born between 1992 and 2001 (n = 19,130) underwent a telephone interview designed to screen for child psychiatric disorders, including ASD. To ensure full coverage of child psychiatric disorders, data were also retrieved from population-based health registers. We investigated the coexistence of eight psychiatric disorders known to coexist with ASDs in probands and their co-twins. Results Half of the individuals with ASDs (50.3%) had four or more coexisting disorders and only 4% did not have any concomitant disorder. The ‘healthy co-twin’ in ASD discordant monozygotic twin pairs was very often (79% of boys and 50% of girls) affected by at least one non-ASD disorder. The corresponding figures for ASD discordant dizygotic twin pairs were significantly lower (46% of males and 30% of females). Conclusions Detailed phenotypic descriptions including symptoms of problems associated with a wide range of child psychiatric disorders may aid in unraveling the genetic architecture of ASD and should guide the development of intervention strategies addressing each problem type specifically.
