RESUMO

Delineation of a developmental and behavioral trajectory is a key-topic in the context of a genetic syndrome. Short- and long-term implications concerning school outcome, independent living, and working opportunities are strictly linked to the cognitive and behavioral profile of an individual. For the first time, we present a longitudinal characterization of the adaptive and behavioral profile of a pediatric sample of 32 individuals with Sotos Syndrome (SoS) (18 males, 14 females; mean age 9.7 ± 4 years, eight carrying the NSD1 5q35 microdeletion and 24 with an intragenic mutation). We performed two clinical assessments: at baseline (T0) and at distance evaluation (T1) of adaptive and behavioral skills with a mean distance of 1.56 ± 0.95 years among timepoints. Our study reports a stability over the years-meant as lack of statistically significant clinical worsening or improvement-of both adaptive and behavioral skills investigated, regardless the level of Intellectual Quotient and chronological age at baseline. However, participants who did not discontinue intervention among T0 and T1, were characterized by a better clinical profile in terms of adaptive skills and behavioral profile at distance, emphasizing that uninterrupted intervention positively contributes to the developmental trajectory.

RESUMO

Background: Sotos syndrome (SoS) is a rare overgrowth genetic disease caused by intragenic mutations or microdeletions of the NSD1 gene located on chromosome 5q35. SoS population might present cognitive impairment and a spectrum of behavioral characteristics, with a worse profile in patients with microdeletion. Although patients with SoS are known to have impaired sleep habits, very little data are available. The present study aimed to assess the prevalence of sleep disorders (SDs) in a pediatric cohort of patients with SoS and their correlation with neuropsychiatric profiles. Methods: We included patients with a SoS diagnosis and age < 18 years; all patients underwent a comprehensive neuropsychological assessment, including evaluation of cognition, adaptive functions through the Adaptive Behavior Assessment System-Second Edition (ABAS-II), and behavioral problems using the Achenbach Child Behavior Checklist (CBCL) and Conners' Parent Rating Scale-Revised (CPRS-R:L) questionnaire. To investigate the presence of SD parents, the Sleep Disturbance Scale for Children (SDSC) was completed. Results: Thirty-eight patients (M 61%, F 39%, mean age 11.1 ± 4.65 years) were included in the study. Although only two had a prior SD diagnosis, 71.1% (N = 27) exhibited pathological scores on SDSC. No statistically significant associations were found between positive SDSC results and genetic microdeletion, intellectual disability (ID), or other medical conditions/treatments. However, a positive correlation emerged between SDSC scores and Conners' Global Index (p = 0.048) and Restless/Impulsive (p = 0.01) scores, CBCL externalizing (p = 0.02), internalizing (p = 0.01), and total scores (p = 0.05). Conversely, a negative linear relationship was observed between the SDSC score and the ABAS GAC and ABAS CAD scores (p = 0.025). Conclusion: We detected an SD in 71.1% of our sample, with a positive relation between SD and internalizing and externalizing symptom levels, especially hyperactivity and impulsivity. Our study demonstrated a high prevalence of SD in pediatric patients with SoS, highlighting that all patients should be screened for this problem, which has a great impact on the quality of life of patients and their families.
