We aimed to identify unique constellations of sensory phenotypes for genetic etiologies associated with diagnoses of autism spectrum disorder (ASD) and intellectual disability (ID). Caregivers reported on sensory behaviors via the Sensory Profile for 290 participants (younger than 25 years of age) with ASD and/or ID diagnoses, of which…

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…

Godoy-Giménez, Marta; González-Rodríguez, Antonio; Cañadas, Fernando; Estévez, Angeles F.; Sayans-Jiménez, Pablo – Journal of Autism and Developmental Disorders, 2018
The Broad autism phenotype (BAP) refers to a set of subclinical behavioural characteristics qualitatively similar to those presented in Autism spectrum disorders (ASDs). The BAP questionnaire (BAPQ) has been widely used to assess the BAP both in relatives of ASD people and within the general population. The current study presents the first Spanish…

Prevalence of self-injurious behavior (SIB) is as high as 50% among children with autism spectrum disorder (ASD). Identification of risk factors for the development of SIB is critical to early intervention and prevention. However, there is little empirical research utilizing a prospective design to identify early risk factors for SIB. The purpose…

Staal, Wouter G.; de Krom, Mariken; de Jonge, Maretha V. – Journal of Autism and Developmental Disorders, 2012
Recently the "DRD3" gene has been associated with ASD in two independent samples. Follow up analysis of the risk allele of the SNP rs167771 in 91 subjects revealed a significant association with a specific type of repetitive behavior: the factor "insistence on sameness" (IS) derived from the Autism Diagnostic Interview. This risk allele was…

Oliver, Chris; Berg, Katy; Moss, Jo; Arron, Kate; Burbidge, Cheryl – Journal of Autism and Developmental Disorders, 2011
We investigated autism spectrum disorder (ASD) symptomatology, hyperactivity and affect in seven genetic syndromes; Angelman (AS; n = 104), Cri du Chat (CdCS; 58), Cornelia de Lange (CdLS; 101), Fragile X (FXS; 191), Prader-Willi (PWS; 189), Smith-Magenis (SMS; 42) and Lowe (LS; 56) syndromes (age range 4-51). ASD symptomatology was heightened in…

Wallace, Anna E.; Anderson, George M.; Dubrow, Robert – Journal of Autism and Developmental Disorders, 2008
Associations between obstetric and parental psychiatric variables and subjects' Autism Diagnostic Interview-Revised (ADI-R) and Autism Diagnostic Observation Schedule (ADOS) domain scores were examined using linear mixed effects models. Data for the 228 families studied were provided by the Autism Genetic Resource Exchange. Hypertension (P =…

Walz, Nicolay Chertkoff – Journal of Autism and Developmental Disorders, 2007
Research examining autistic symptoms in Angelman syndrome (AS) is limited. The goal of this study was to further characterize the nature of stereotyped behaviors, social interaction deficits, and developmental disturbances in individuals with AS. Parents of 248 individuals between the ages of 3 and 22 completed a survey of autistic symptomatology…

Rapin, Isabelle – Journal of Autism and Developmental Disorders, 2002
A reaction to Sowell's book raises issues about behaviorally based diagnoses, stressing that developmental disorders are behaviorally defined dimensions along a continuum with no crisp partition between normalcy and disorders. It sees developmental disorders as usually the expression of extremely complex, multigenic influences on brain…

Dykens, Elisabeth; And Others – Journal of Autism and Developmental Disorders, 1988
Evaluation of the cognitive, behavioral, and adaptive functioning of 12 retarded men with fragile X syndrome indicated that fragile X men were largely indistinguishable from comparison groups. They were, however, significantly more likely to have achieved levels of adaptive functioning commensurate with their intellectual abilities. (Author/DB)

Cuccaro, Michael L.; Shao, Yujun; Bass, Meredyth P.; Abramson, Ruth K.; Ravan, Sarah A.; Wright, Harry H.; Wolpert, Chantelle M.; Donnelly, Shannon L.; Pericak-Vance, Margaret A. – Journal of Autism and Developmental Disorders, 2003
This study examined Autism Diagnostic Interviews Revised (ADI-R) data for 69 autistic subjects from multiplex (MP) families (with more than one autistic member) and 88 autistic subjects from singleton (SP) families (with only one autistic member). Multivariate analysis revealed no differences between verbal or nonverbal MP and SP groups for ADI-R…

Dykens, Elisabeth M.; And Others – Journal of Autism and Developmental Disorders, 1993
Adaptive behavior in mentally retarded males with fragile X syndrome was longitudinally examined in 17 subjects, ages 1 to 17. Findings included relative strength in daily living skills and weakness in socialization only for older subjects, and significant declines in adaptive behavior scores from first to second testing for the older subjects.…
