Characteristics of Autism Spectrum Disorder in Sotos syndrome
Chloe Lane, Elizabeth Milne, Megan Freeth
Sotos syndrome is a congenital overgrowth disorder with an incidence of approximately 1 in 14,000. This study investigated behavioural characteristics of Autism Spectrum Disorder (ASD) within a large cohort of individuals with Sotos syndrome (n = 78). As measured by theSocial Responsiveness Scale, second edition (SRS-2), 65 participants (83.33%) met clinical cut-off (T-score ≥ 60). There was no significant gender difference in symptom severity. There was a significant effect of age, with lower scores observed in early childhood and adulthood, compared to childhood. Furthermore, individuals with Sotos syndrome appear to display a trait profile that is similar to that identified in ASD. Overall, these findings indicate that the majority of individuals with Sotos syndrome display clinically significant behavioural symptomatology associated with ASD.
