An Observational Study of Social Interaction Skills and Behaviors in Cornelia de Lange, Fragile X and Rubinstein-Taybi Syndromes / Katherine ELLIS in Journal of Autism and Developmental Disorders, 50-11 (November 2020)
[article]
Titre : An Observational Study of Social Interaction Skills and Behaviors in Cornelia de Lange, Fragile X and Rubinstein-Taybi Syndromes Type de document : Texte imprimé et/ou numérique Auteurs : Katherine ELLIS, Auteur ; Chris OLIVER, Auteur ; Chrysi STEFANIDOU, Auteur ; Ian APPERLY, Auteur ; Jo MOSS, Auteur Article en page(s) : p.4001-4010 Langues : Anglais (eng) Mots-clés : Eye gaze Fragile X syndrome Genetics behavioural Neurodevelopmental disorders Social behavior Index. décimale : PER Périodiques Résumé : We directly assessed the broader aspects of sociability (social enjoyment, social motivation, social interaction skills and social discomfort) in individuals with Cornelia de Lange (CdLS), fragile X (FXS) and Rubinstein-Taybi syndromes (RTS), and their association with autism characteristics and chronological age in these groups. Individuals with FXS (p?< 0.01) and RTS (p?< 0.01) showed poorer quality of eye contact compared to individuals with CdLS. Individuals with FXS showed less person and more object attention than individuals with CdLS (p?< 0.01). Associations between sociability and autism characteristics and chronological age differed between groups, which may indicate divergence in the development and aetiology of different components of sociability across these groups. Findings indicate that individuals with CdLS, FXS and RTS show unique profiles of sociability.

Titre : A Behavioural Assessment of Social Anxiety and Social Motivation in Fragile X, Cornelia de Lange and Rubinstein-Taybi Syndromes Type de document : Texte imprimé et/ou numérique Auteurs : Hayley CRAWFORD, Auteur ; Joanna MOSS, Auteur ; Laura GROVES, Auteur ; Robyn DOWLEN, Auteur ; Lisa NELSON, Auteur ; Donna REID, Auteur ; Chris OLIVER, Auteur Article en page(s) : p.127-144 Langues : Anglais (eng) Mots-clés : Cornelia de Lange syndrome Down syndrome Fragile X syndrome Rubinstein-Taybi syndrome Social anxiety social motivation Index. décimale : PER Périodiques Résumé : Unique socio-behavioural phenotypes are reported for individuals with different neurodevelopmental disorders. Here, the effects of adult familiarity and nature of interaction on social anxiety and social motivation were investigated in individuals with fragile X (FXS; n = 20), Cornelia de Lange (CdLS; n = 20) and Rubinstein-Taybi (RTS; n = 20) syndromes, compared to individuals with Down syndrome (DS; n = 20). The Social Anxiety and Motivation Rating Scale was employed whilst participants completed four social tasks, each administered separately by a familiar adult, and also by an unfamiliar adult. Compared to participants with DS, those with FXS and RTS exhibited high levels of social anxiety but similar levels of social motivation. Participants with CdLS showed heightened social anxiety and reduced social motivation only during interactions with an unfamiliar adult when active participation was voluntary.

Titre : Brief Report: Contrasting Profiles of Everyday Executive Functioning in Smith–Magenis Syndrome and Down Syndrome Type de document : Texte imprimé et/ou numérique Auteurs : Lucy WILDE, Auteur ; Chris OLIVER, Auteur Article en page(s) : p.2602-2609 Langues : Anglais (eng) Mots-clés : Executive function BRIEF-P Smith–Magenis syndrome Down syndrome Index. décimale : PER Périodiques Résumé : Everyday executive function (EF) was examined in Smith–Magenis syndrome (SMS), associated with high risk of behaviour disorder, and Down syndrome (DS), associated with relatively low risk of behaviour disorder. Caregivers of 13 children with SMS and 17 with DS rated everyday EF using the Behavioral Rating Inventory of Executive Functioning-Preschool. Greater everyday EF deficits relative to adaptive ability were evident in SMS than in DS. The SMS profile of everyday EF abilities was relatively uniform; in DS emotional control strengths and working memory weaknesses were evident. Findings implicate broad everyday EF difficulties in SMS compared to DS, corresponding with increased rates of behaviour disorder in SMS. Findings further suggest that everyday EF profiles may, in part, be syndrome related.

Titre : Brief Report: A Longitudinal Study of Excessive Smiling and Laughing in Children with Angelman Syndrome Type de document : Texte imprimé et/ou numérique Auteurs : Dawn ADAMS, Auteur ; Kate HORSLER, Auteur ; Rebecca MOUNT, Auteur ; Chris OLIVER, Auteur Année de publication : 2015 Article en page(s) : p.2624-2627 Langues : Anglais (eng) Mots-clés : Angelman syndrome Behavioral phenotype Intellectual disability Aging Behavior Index. décimale : PER Périodiques Résumé : Elevated laughing and smiling is a key characteristic of the Angelman syndrome behavioral phenotype, with cross-sectional studies reporting changes with environment and age. This study compares levels of laughing and smiling in 12 participants across three experimental conditions [full social interaction (with eye contact), social interaction with no eye contact, proximity only] at two data points. No differences were noted in frequency of laughing and smiling over time in any condition. However, with age as a covariate, the frequency of laughing and smiling decreased over time in the full social interaction (with eye contact) condition only. As this is the first longitudinal study to explore these behaviors in Angelman syndrome, the results suggest a gene–environment–time interaction within the behavioral phenotype.

Titre : Characteristics of autism spectrum disorder in Cornelia de Lange syndrome Type de document : Texte imprimé et/ou numérique Auteurs : Jo MOSS, Auteur ; Patricia HOWLIN, Auteur ; Iliana MAGIATI, Auteur ; Chris OLIVER, Auteur Année de publication : 2012 Article en page(s) : p.883-891 Langues : Anglais (eng) Mots-clés : Autism spectrum disorder Cornelia de Lange syndrome behavioural phenotypes genetic syndromes neurodevelopmental disorders Index. décimale : PER Périodiques Résumé : Background: The prevalence of autism spectrum disorder (ASD) symptomatology is comparatively high in Cornelia de Lange syndrome (CdLS). However, the profile and developmental trajectories of these ASD characteristics are potentially different to those observed in individuals with idiopathic ASD. In this study we examine the ASD profile in CdLS in comparison to a matched group of individuals with ASD. Method: The Autism Diagnostic Observation Schedule (ADOS) was administered to 20 individuals with CdLS (mean age = 11.34; range = 6–13 years) and 20 individuals with idiopathic ASD (mean age = 10.42; range = 8–11 years). Participants were matched according to adaptive behaviour and receptive language skills. Results: Sixty-five percent (N = 13) of individuals with CdLS met the cut-off score for autism on the total ADOS score. Further analysis at domain and item level indicated that individuals with CdLS showed significantly less repetitive behaviour, (specifically sensory interests); more eye contact, more gestures and less stereotyped speech than the ASD group. The CdLS group also showed higher levels of anxiety. Conclusions: The comparison between CdLS and idiopathic ASD indicates subtle group differences in the profile of ASD symptomatology that are not accounted for by degree of intellectual disability or receptive language skills. These differences may not be evident when relying solely upon clinical and domain level scores, but may be distinguishing features of the ASD presentations in the two disorders. The findings have implications for the conceptualisation and assessment of ASD in individuals with genetic syndromes.
