Examining sub-threshold autistic traits in non-autistic first-degree relatives of individuals on the autism spectrum, known as the Broad Autism Phenotype (BAP), could provide new insights into the associations and familial aggregation of autistic traits. This study was a retrospective cross-sectional study of parents (n = 1008), probands with…

The purpose of this paper was to examine the physical, emotional, social and school functioning domains of quality of life of individuals with Fragile X Syndrome, in relation to mental health and sleep patterns to gain a better understanding of how these aspects are affected by the disorder. This study included 119 individuals with Fragile X…

This study investigated sex and age differences in autistic behaviours in children with neurofibromatosis type 1 (NF1) who scored within the clinical range on the Social Responsiveness Scale - Second Edition (T score [greater than or equal to] 60). Thirty-four males and 28 females (3-16 years) were assessed with the Autism Diagnostic Observation…

Tofani, Marco; Scarcella, Lucia; Galeoto, Giovanni; Giovannone, Federica; Sogos, Carla – Journal of Autism and Developmental Disorders, 2023
There is increasing literature showing that the presentation of Autism Spectrum Disorder (ASD) could be different according to the sex of the patient. Through the analysis of the Autism Diagnostic Interview Revised interview results of a study group consisting of 56 preschool children diagnosed with ASD potential differences in the presentation of…

Fielding-Gebhardt, Heather; Bredin-Oja, Shelley L.; Warren, Steven F.; Brady, Nancy C. – Journal of Autism and Developmental Disorders, 2021
Accurate representation of autism spectrum disorder (ASD) in fragile X syndrome (FXS) is necessary for the field. We examined classifications of ASD using three approaches--Autism Diagnostic Observation Schedule (ADOS-2; Lord et al. 2012), Childhood Autism Rating Scale (CARS2-ST; Schopler et al. 2010), and Vineland Adaptive Behavior Scales…

This study explored the physical and clinical phenotype of Bangladeshi children with autism spectrum disorder (ASD). A totally of 283 children who were referred for screening and administered Module 1 of the Autism Diagnostic Observation Schedule (ADOS) were included. Overall, 209 met the ADOS algorithmic cutoff for ASD. A trend for greater weight…

Gold-standard diagnostic assessments of autism spectrum disorder (ASD) symptomatology were conducted on 63 children (mean CA: 8.81 years) with 7q11.23 duplication syndrome, one of the copy number variants identified by Sanders et al. ("Neuron" 70:863-885, 2011a) as associated with ASD. ASD classification rate was 39.6% for the Autism…

Cochran, Lisa; Welham, Alice; Oliver, Chris; Arshad, Adam; Moss, Joanna F. – Journal of Autism and Developmental Disorders, 2019
Age-related behavioural change in Cornelia de Lange syndrome is poorly understood. We report a 7 year follow-up study of adaptive behaviour, autism spectrum disorder symptomatology, language skills and behavioural characteristics in 30 individuals with Cornelia de Lange syndrome, compared with 18 individuals with Cri du Chat syndrome. The…

Klein-Tasman, Bonita P.; van der Fluit, Faye; Mervis, Carolyn B. – Journal of Autism and Developmental Disorders, 2018
To characterize autism spectrum-related symptomatology in children with Williams syndrome (WS) with phrase speech or fluent language, the Autism Diagnostic Observation Schedule Module 2 or 3 was administered. The cutoff for autism spectrum was met by 35% (14/40) who completed Module 2 and 30% (18/60) who completed Module 3. Similarities and…

The Study to Explore Early Development (SEED) is a multi-site case-control study designed to explore the relationship between autism spectrum disorder (ASD) phenotypes and etiologies. The goals of this paper are to (1) describe the SEED algorithm that uses the Autism Diagnostic Interview-Revised (ADI-R) and Autism Diagnostic Observation Schedule…

Assessment of Pretend Play in Prader-Willi Syndrome: A Direct Comparison to Autism Spectrum Disorder
Zyga, Olena; Russ, Sandra; Ievers-Landis, Carolyn E.; Dimitropoulos, Anastasia – Journal of Autism and Developmental Disorders, 2015
Children with Prader-Willi syndrome (PWS) are at risk for autism spectrum disorder (ASD), including pervasive social deficits. While play impairments in ASD are well documented, play abilities in PWS have not been evaluated. Fourteen children with PWS and ten children with ASD were administered the Autism Diagnostic Observation Schedule (ADOS)…

Angkustsiri, Kathleen; Goodlin-Jones, Beth; Deprey, Lesley; Brahmbhatt, Khyati; Harris, Susan; Simon, Tony J. – Journal of Autism and Developmental Disorders, 2014
High prevalence of autism spectrum disorders (ASD) has been reported in 22q11.2DS, although this has been based solely on parent report measures. This study describes the presence of ASD using a procedure more similar to that used in clinical practice by incorporating history (Social Communication Questionnaire) AND a standardized observation…

Research on sex-related differences in Autism Spectrum Disorder (ASD) has been impeded by small samples. We pooled 28 datasets from 18 sites across nine European countries to examine sex differences in the ASD phenotype on the ADI-R (376 females, 1763 males) and ADOS (233 females, 1187 males). On the ADI-R, early childhood restricted and…

Wolfenden, C.; Wittkowski, A.; Hare, D. J. – Journal of Autism and Developmental Disorders, 2017
The prevalence of autism spectrum disorder (ASD) in many genetic disorders is well documented but not as yet in Mucopolysaccharidosis type III (MPS III). MPS III is a recessively inherited metabolic disorder and evidence suggests that symptoms of ASD present in MPS III. This systematic review examined the extant literature on the symptoms of ASD…
