Furthermore, distinct ASD phenotypes may be associated with each genetic syndrome (Moss and Howlin 2009). Although some disorders display similar trait profiles to that of ASD, some congenital syndromes are associated with subtly different profiles of ASD symptomatology (e.g. Within the total sample, 55.13 % (n = 43) were in the severe clinical range (T-score ≥76), 19.23 % (n = 15) were in the moderate clinical range (T-score of 66–75) and 8.97 % (n = 7) of scores were in the mild clinical range (T-score of 60–65). In the present study, there was no effect of gender on symptom severity, indicating that there is no significant difference between the prevalence of behavioural characteristics associated with ASD in males and females with Sotos syndrome. Los Angeles, CA: Western Psychological Services. The NSD1 and EZH2 overgrowth genes, similarities and differences. The risk to have a child who is a carri… The disorder may be accompanied by autism, mild mental retardation, delayed motor, cognitive, and social development, hypotonia (low muscle tone), and speech impairments. However, as this study used a cross-sectional design, an important future direction will be to examine the effect of age using a longitudinal design, so that developmental trajectories can be effectively tracked. The repetitive behaviour scale. Trad, P. V., Schlefer, E., Hertzig, M., & Kernberg, P. F. (1991). Seltzer, M. M., Shattuck, P., Abbeduto, L., & Greenberg, J. S. (2004). Until recently, doctors would diagnose Sotos syndrome on the basis of several common features that include characteristic facial appearance, There was also no significant group × subscale interaction, (F(4,1137) = 1.40, p = .23), demonstrating that children with Sotos syndrome appear to display a very similar symptom severity and profile of behaviour to that of children with ASD (see Fig. All participants with diagnoses of both Sotos syndrome and ASD (n = 16) scored above clinical cut-off. Kurotaki, N., Imaizumi, K., Harada, N., Masuno, M., Kondoh, T., Nagai, T., et al. 1). In this study we describe the levels of clinically significant behavior in participants with Sotos syndrome relative to three matched contrast groups in which the behavioral phenotype is well documented (Autism Spectrum Disorder, ASD; Prader-Willi, and Down syndromes). Abstract Sotos syndrome is a congenital overgrowth disorder … This is an important finding as there is a significant gender difference in diagnosis of ASD, with males more likely to receive a diagnosis than females (Fombonne 2009). Soto Syndrome & Autism In: Genetic Alliance. Confirmatory factor analytic structure and measurement invariance of quantitative autistic traits measured by the social responsiveness scale-2. 2002). (2015) found that 26 of 38 participants with Sotos syndrome (68.42 %) met clinical cut-off for ASD, as measured by total score on the Lifetime version of the SCQ (clinical cut-off was considered as a total score ≥15). However, our findings indicate that severity of ASD symptomatology is comparable in both males and females with Sotos syndrome. The reliability and validity of the social responsiveness scale in a UK general child population. Introduction. Sotos syndrome Support Association (SSSA) is made up of families, physicians, genetic counselors, and health care agencies throughout the United States. Licensing was received by the publishers of the SRS-2 to allow online administration of the questionnaire. 3 doctors agree. The findings from the present study demonstrate a high prevalence of autistic symptomatology within the Sotos population and suggest that the majority of individuals with Sotos syndrome display clinically significant behavioural symptomatology associated with ASD. Lane, C., Milne, E. & Freeth, M. Characteristics of Autism Spectrum Disorder in Sotos Syndrome. 2004). Baron-Cohen, S., Scott, F. J., Allison, C., Williams, J., Bolton, P., Matthews, F. E., & Brayne, C. (2009). 56 years experience Family Medicine. Thus, it will be useful for future research to investigate factors which may affect ASD symptomatology within this population, such as developmental level, cognitive ability and verbal ability. Sotos syndrome is an autosomal dominant disorder caused by mutations in the NSD1 gene with an incidence of approximately 1:14,000. In addition, the profile of ASD symptomatology may be affected by age which could explain differences in the relative severity of impairment in social communication impairment and restricted interests and repetitive behaviours in the present study and the findings from Sheth et al. The results suggest that mutations in NSD1 can contribute to autism, Tatton-Brown says. PubMed  A few families have been described with more than one affected family member. (2015). However, as this study measured autistic features using a questionnaire, it will be important for future research to explore the profile of ASD symptomatology in Sotos syndrome in more detail, using clinical evaluations, such as the Autism Diagnostic Observation Schedule (Lord et al. Mean item scores for the five subscales identified in the Frazier et al. Van Eeghen et al. 2015; Timonen-Soivio et al. The estimated incidence is 1 in 14,000 (Tatton-Brown and Rahman 2004). The aim of the present study was to investigate the prevalence and profile of ASD characteristics within a large cohort of individuals with Sotos syndrome. They will be taller than their siblings and peers. But most studies were case reports, and the largest included just 38 participants with Sotos syndrome and offered few details about the prevalence and severity of autism features. The autism diagnostic observation schedule—generic: A standard measure of social and communication deficits associated with the spectrum of autism. “The research adds to an evolving cognitive picture associated with Sotos syndrome and is very important in empowering patients and families to access appropriate care and support,” says Kate Tatton-Brown, consultant in clinical genetics at St. George’s, University of London, who was not involved in the study. Research in Developmental Disabilities, 33(3), 944–950. These inherited cases … American Journal of Medical Genetics Part C-Seminars in Medical Genetics, 163 C(2), 86–91. These additional factors can be used to explore the profile of ASD symptomatology. (2015) used the Lifetime form which is concerned with both behaviours that have been present at any point in the individual’s life, as well as behaviours that occurred during a 12 month period (4–5 years of age). Nature Genetics, 30(4), 365–366. 2008). Error bars show standard error. The risk for two carrier parents to both pass the abnormal variant gene and, therefore, have an affected child is 25% with each pregnancy. Twelve syndromes were included in this review and a quality-weighted effect prevalence was generated for each of the syndromes. Haploinsufficiency of the NSD1 (nuclear receptor binding SET domain protein 1) gene was first identified as the primary cause of Sotos syndrome in 2002 (Kurotaki et al. These individuals show restricted interests, compulsive behaviors, repetitive speech, social anxiety and reliance on routine. As the majority of cases of Sotos syndrome are caused by abnormality of the NSD1 gene, our findings provide further evidence to suggest a possible genetic mechanism associated with ASD. Morrow et al.

YES IT IS A TYPE : Yes Asperger syndrome is a type of high function autism. There was a significant effect of age, with lower scores observed in early childhood and adulthood, compared to childhood. 2006; Baron-Cohen et al. doi:10.1097/00019605-200410000-00001. The SRS-2 provides a quantitative measure of autistic symptomatology and is designed to measure severity of deficit in reciprocal social interaction, as well as deficit in restricted interests and repetitive behaviours. https://doi.org/10.1007/s10803-016-2941-z, DOI: https://doi.org/10.1007/s10803-016-2941-z, Over 10 million scientific documents at your fingertips, Not logged in The analysis identified a significant difference between T-scores on the social communication impairment (M = 75.57, SD = 15.43) and restricted interests and repetitive behaviours (M = 79.45, SD = 16.44) subscales, indicating that individuals with Sotos syndrome display greater difficulty with restricted interests and repetitive behaviours, compared with social communication impairment (t(77) = 4.37, p < .001). Of these, three were case studies of individuals who had co-morbid diagnoses of Sotos syndrome and ASD. The numbers represent total number of participants in each category. Autism spectrum disorder (ASD) is a developmental disorder associated with social communication impairment and restricted interests and repetitive behaviours. The behavioral characteristics of Sotos syndrome. Additionally, Trad et al. Thus, this review provides evidence for increased prevalence of ASD symptomatology in genetic syndromes and suggests significant variability in prevalence between syndromes.

ASD was not mentioned in the study information, in order to avoid biasing the sample. Sotos syndrome was not included in this study as it is not associated with mutations in a tumour-suppressor gene and is therefore not biologically related to TSC, NF1 or EUC.

In d, scores in the severe range were reported in 8 individuals (80 %). American Journal of Human Genetics, 77(2), 193–204. Participants with Sotos syndrome scored significantly lower than the ASD group on the repetitive behaviour subscale of the SCQ but there were no significant differences between the Sotos and ASD groups on the social communication and social interaction subscales. Sotos syndrome is an overgrowth syndrome characterized by macrocephaly, advanced bone age, characteristic facial features, and learning disabilities, caused by mutations or deletions of the NSD1 gene, located at 5q35.Sotos syndrome has been described in a number of patients with autism spectrum disorders, suggesting that NSD1 could be involved in other cases of autism and … Sheth et al.

Based on previous literature, the variability of ASD symptom severity within the Sotos population is not clear and a detailed profile analysis of ASD symptomatology has not been established. 1 thank. A recent systematic review and meta-analysis investigated the prevalence of reported ASD symptomatology in a range of genetic syndromes (Richards et al. As well as reporting a diagnosis of Sotos syndrome, some respondents reported that their child or partner also had a diagnosis of ASD (n = 16), an anxiety disorder (n = 10) or ADHD (n = 4).
