Are there differences in the behavioural phenotypes of Autism Spectrum Disorder probands from simplex and multiplex families? / Lauren J. TAYLOR in Research in Autism Spectrum Disorders, 11 (March 2015)
[article]
Titre : Are there differences in the behavioural phenotypes of Autism Spectrum Disorder probands from simplex and multiplex families? Type de document : Texte imprimé et/ou numérique Auteurs : Lauren J. TAYLOR, Auteur ; Murray T. MAYBERY, Auteur ; John WRAY, Auteur ; David RAVINE, Auteur ; Anna HUNT, Auteur ; Andrew J. O. WHITEHOUSE, Auteur Article en page(s) : p.56-62 Langues : Anglais (eng) Mots-clés : Autism Spectrum Disorder Behavioural phenotype Simplex and multiplex families Index. décimale : PER Périodiques Résumé : Recent research suggests that different genetic pathways may operate for families with one child affected with Autism Spectrum Disorder (simplex ASD), compared to families that have multiple affected children (multiplex ASD). In this study, we investigated possible differences in the behavioural phenotypes of probands from simplex and multiplex ASD families using parent-report and standardised behavioural measures. Participants were 59 probands from multiplex ASD families (28 families), who were each matched on chronological age and sex with two probands from simplex families. Probands from multiplex families had greater social impairment (measured using the Social Responsiveness Scale) and worse pragmatic language (on the Children's Communication Checklist-2) than probands from simplex families. However, the multiplex children had less severe symptoms than the simplex children on the ADOS-G, and a significantly higher proportion of multiplex children did not meet autism spectrum cut-offs on this measure. These findings indicate that there are behavioural differences in children with ASD from simplex and multiplex families. In addition, the results reveal an important discrepancy between parent-report and clinician observation of autistic-like characteristics in siblings of an affected child, which may have implications for the assessment and diagnosis of ASD.
