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…

Neufeld, Janina; Hederos Eriksson, Lisa; Hammarsten, Richard; Lundin Remnélius, Karl; Tillmann, Julian; Isaksson, Johan; Bölte, Sven – Autism: The International Journal of Research and Practice, 2021
Atypical sensory processing is prevalent across neurodevelopmental conditions and a key diagnostic criterion of autism spectrum disorder. It may have cascading effects on the development of adaptive functions. However, its unique contribution to adaptive functioning and the genetic/environmental influences on this link are unclear. In a clinically…

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…

Fielding-Gebhardt, Heather; Bredin-Oja, Shelley L.; Warren, Steven F. – American Journal on Intellectual and Developmental Disabilities, 2021
The development of an expressive language score for people with autism based on the ADOS-2 was recently reported by Mazurek et al. (2019). The current study examined the construct validity of the ADOS-2 expressive language score (ELS) in a sample of adolescents with fragile X syndrome (n = 45, 10 girls), a neurodevelopmental disorder with high…

Emerging research suggests that caregiving environments and genetic variants independently contribute to social functioning in children with typical development or autism spectrum disorder (ASD). However, biologically plausible interactive models and complimentary assessment of mechanisms are needed to: (1) explain considerable social…

Rubenstein, Eric; Wiggins, Lisa D.; Schieve, Laura A.; Bradley, Chyrise; DiGuiseppi, Carolyn; Moody, Eric; Pandey, Juhi; Pretzel, Rebecca Edmondson; Howard, Annie Green; Olshan, Andrew F.; Pence, Brian W.; Daniels, Julie – Autism: The International Journal of Research and Practice, 2019
The autism spectrum disorder phenotype varies by social and communication ability and co-occurring developmental, behavioral, and medical conditions. Etiology is also diverse, with myriad potential genetic origins and environmental risk factors. Examining the influence of parental broader autism phenotype--a set of sub-clinical characteristics of…

Klein-Tasman, Bonita P.; Mervis, Carolyn B. – Journal of Autism and Developmental Disorders, 2018
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…

Campbell, Susan B.; Northrup, Jessie B.; Tavares, Amy B. – Autism: The International Journal of Research and Practice, 2019
Children with autism spectrum disorder often demonstrate difficulties with self-regulation, although studies of this construct in young children with autism spectrum disorder are limited. In this study, developmental changes were examined using a measure of self-regulation appropriate for young children, resistance to temptation. At 22, 28, and 34…

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)…

Klusek, Jessica; Losh, Molly; Martin, Gary E. – Autism: The International Journal of Research and Practice, 2014
While there is a strong sex bias in the presentation of autism, it is unknown whether this bias is also present in subclinical manifestations of autism among relatives, or the broad autism phenotype. This study examined this question and investigated patterns of co-occurrence of broad autism phenotype traits within families of individuals with…

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…

Connolly, John J.; Glessner, Joseph T.; Hakonarson, Hakon – Child Development, 2013
Efforts to understand the causes of autism spectrum disorders (ASDs) have been hampered by genetic complexity and heterogeneity among individuals. One strategy for reducing complexity is to target endophenotypes, simpler biologically based measures that may involve fewer genes and constitute a more homogenous sample. A genome-wide association…
