Growing evidence suggests that autistic females are more likely to be diagnostically overlooked than males, perhaps due to differences in ASD presentations (van Wijngaarden-Cremers in JAMA 44:627-635, 2014). To investigate specific behaviours in which differences lie, we analysed profiles of 777 children using the Childhood Autism Rating Scale…

Lundin Remnélius, Karl; Neufeld, Janina; Isaksson, Johan; Bölte, Sven – Journal of Autism and Developmental Disorders, 2022
This study investigated the association between autism and self-reported eating problems and the influence of gender on the association, in a sample of adolescent and adult twins (N = 192). Autistic traits and autism diagnosis were associated with both total and specific eating problems, including selective eating and sensory sensitivity during…

Neal, Corinne N.; Brady, Nancy C.; Fleming, Kandace K. – American Journal on Intellectual and Developmental Disabilities, 2022
This study analyzed narratives of male and female adolescents with fragile X syndrome (FXS). The impact of structural language, cognition and autism symptomatology on narrative skills and the association between narratives and literacy were examined. Narratives from 32 adolescents with FXS (24 males, 8 females) were analyzed for macrostructure.…

Markiewicz, Katarzyna; Kaczmarek, Bozydar L. J.; Filipiak, Sara – Journal of Autism and Developmental Disorders, 2021
The study aimed to identify the mediating role of emotional intelligence and social competences in the relationship between gender and broad autism phenotype (BAP) as well as between age and BAP. It comprised 85 parents of children with ASD. They completed the questionnaires of Autism-Spectrum Quotient, social competences, and emotional…

Hu, Valerie W.; Hong, Yi; Xu, Minyi; Shu, Henry T. – Autism: The International Journal of Research and Practice, 2021
Although differences in DNA methylation have been associated with both syndromic and idiopathic autism, differential methylation has not been examined previously with respect to sex differences. The goals of this study were to (1) identify differences in the DNA methylation profiles of lymphoblastoid cell lines derived from a subgroup of severely…

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…

To date, health related quality of life (QoL) has not been systematically evaluated in youth with fragile X syndrome (FXS), the most common single gene cause of autism and the most common inherited form of developmental disability. We describe QoL data gathered using the Pediatric Quality of Life Inventory (PedsQL) completed online by 364 parents…

Saldarriaga-Gil, Wilmar; Cabal-Herrera, Ana Maria; Fandiño-Losada, Andrés; Vásquez, Andrés; Hagerman, Randi; Tassone, Flora – Journal of Applied Research in Intellectual Disabilities, 2021
Background: Fragile X syndrome (FXS) is the most common cause of inherited intellectual disability and autism spectrum disorder (ASD). In Colombia, there are no screening or testing protocols established for the diagnosis of FXS. In this study, we aimed to describe the diagnostic trends of FXS in Colombia. Methods: Data were included on 1322…

Nag, Heidi Elisabeth; Naerland, Terje – Journal of Intellectual Disabilities, 2021
Smith-Magenis syndrome (SMS) is a genetic syndrome most often caused by a deletion on chromosome 17 or more rarely by a mutation in the retinoic acid-induced 1 gene. The aim of this study was to investigate the Developmental Behavior Checklist (DBC) profile of persons with SMS and the associations between behavioural and emotional problems, age,…

Usher, Lauren V.; DaWalt, Leann S.; Hong, Jinkuk; Greenberg, Jan S.; Mailick, Marsha R. – Journal of Autism and Developmental Disorders, 2020
This study examined trajectories of daily living skills, behavior problems, body mass index (BMI), and health conditions spanning nearly a decade in adolescents and adults with fragile X syndrome (N = 134; age range at study end = 19-49 years), examining influences of sex and autism spectrum disorder (ASD) symptoms. Hierarchical linear modeling…

Many neurodevelopmental disorders (NDDs) share common learning and behavioural impairments, as well as features such as dysregulation of the oxytocin hormone. Here, we examined DNA methylation (DNAm) in the 1st intron of the oxytocin receptor gene, "OXTR," in patients with autism spectrum (ASD), attention deficit and hyperactivity (ADHD)…

Harmsen, Irene E. – Journal of Autism and Developmental Disorders, 2019
Empathy is an essential component of human social life. It requires the ability to understand another's mental state and respond with an appropriate emotion or action. Individuals with autism spectrum disorder (ASD) have been described to exhibit atypical empathic responses which limit communication and social interactions. This review highlights…

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…

Barstein, Jamie; Martin, Gary E.; Lee, Michelle; Losh, Molly – Journal of Speech, Language, and Hearing Research, 2018
Purpose: The ability to repair breakdowns in communication is an important pragmatic language skill that helps to maintain clear and meaningful interactions. Examining this ability in genetically based neurodevelopmental disabilities in which pragmatics are affected can provide important information about the precise pragmatic skills impacted…
