The study described in the article above aims to determine the predictive value of joint attention for ASD symptoms as well as the effect of XXX, XXY, and XYY sex chromosome trisomy (SCT), on the early onset of symptoms of autism spectrum disorder (ASD) (Bouw et al., 2023). This is a longitudinal design study that is part of the TRIXY Early Childhood Study—Leiden, The Netherlands. At the study's baseline, 82 kids with SCT were part of the group. 24 girls with
47,XXX, 41 boys with 47,XXY, and 17 boys with 47,XYY made up the study sample (Bouw et al., 2023). The Early Social Communication Scales were used to measure joint attention abilities at baseline during systematic behavior observation of a structured 20-minute play situation. The ESCS is intended to assess the various aspects of early nonverbal communication development. A follow-up assessment was conducted after a year to search for any early signs of ASD in children with SCT who are between the ages of two and four. The assessment that was used was The Modified Checklist for Autism in Toddlers (M-CHAT). Researchers discovered that children with SCT had significantly more symptoms of ASD than children in the general population, with 22% of our cohort having a clinical risk for the disorder, particularly in social interaction and communication (Bouw et al., 2023). Second, at a 1-year follow-up, Joint Attention was found to have predictive value for symptoms of ASD. There were no differences observed between the karyotype-subtypes in this cohort. Additionally, SCT has been linked to a higher risk of vulnerabilities in adaptive social functioning from a very young age (Bouw et al., 2023). These results indicate that an additional X or Y chromosome has a neurodevelopmental impact on social
adaptive development, which is linked to an increased risk of ASD starting in early childhood.
