The Broader Autism Phenotype in Tuberous Sclerosis Complex
Neurology(2018)
摘要
Objective: Evaluate the broader autism phenotype in young children with Tuberous Sclerosis Complex (TSC). Background: Autism spectrum disorder (ASD) has been reported in approximately 50% of individuals with TSC. Detailed phenotyping of ASD through prospectively collected, validated standardized assessments, however, is lacking. Design/Methods: Children ages 0–36 months with TSC participated in the TSC Autism Center of Excellence Network. Children were evaluated longitudinally with Mullen Scales of Early Learning (MSEL), Vineland Adaptive Behavior Scales, 2 nd Edition, Survey Interview (VABS-II), and Preschool Language Scales, 5 th Edition (PLS-5). The Autism Diagnostic Observation Schedule-Second Edition (ADOS-2) and Autism Diagnostic Interview-Revised (ADI-R) were administered at 24 and 36 months at which point a diagnosis of ASD or not ASD was assigned by expert clinical team. Analysis was performed to determine if phenotypic differences existed between ADOS-2 negative/ASD diagnosis negative (non-ASD), ADOS-2 positive/clinical ASD diagnosis negative (Mixed), and ADOS-2 positive/ASD diagnosis positive (ASD) groups. Results: As expected, the ASD group exhibited lower scores on all measures compared to the non-ASD group (p Conclusions: Autism specific characteristics may be present in young children with TSC that do not meet full criteria for ASD. In addition to ASD and non-ASD, a third diagnostic group with mixed features is distinguishable at 24 and 36 months of age.
