sotos syndrome and autism

Pediatric Research, 65(6), 591–598. 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. In each, the lower line depicts a T-score of 60. Chloe Lane. It is a non progressive condition. Average item scores of the Sotos syndrome children for each of the five factors were: emotion recognition (M = 1.90, SD = 0.58), social avoidance (M = 1.09, SD = 0.76), interpersonal relatedness (M = 1.88, SD = 0.66), insistence on sameness (M = 1.76, SD = 0.61) and repetitive mannerisms (M = 1.52, SD = 0.72). This indicates an important relationship between the behavioural phenotypes of Sotos syndrome and ASD. (2002). Sheth et al. The New England Journal of Medicine, 271, 109–116. 2016). Initial descriptions of Sotos syndrome included severe to mild mental retardation. About 95 percent of Sotos syndrome cases occur by spontaneous mutation. To date the majority of research around Sotos syndrome has focused on physical and genetic A few families have been described with more than one affected family member. Sotos syndrome (Tatton-Brown et al. To date, this measure has not been used to investigate quantitative, intragroup autistic features in Sotos syndrome. In summary, this is the largest study to date to investigate symptomatology associated with ASD in individuals with Sotos syndrome. Moss, J., & Howlin, P. (2009). Prevalence of autism-spectrum conditions: UK school-based population study. Until recently, doctors would diagnose Sotos syndrome on the basis of several common features that include characteristic facial appearance, Journal of Medical Genetics, 31(1), 20–32. Bölte, S., Poustka, F., & Constantino, J. N. (2008). The study received ethical approval from the university Departmental Ethics Committee. Zhao, X., Leotta, A., Kustanovich, V., Lajonchere, C., Geschwind, D. H., Law, K., et al. Article  A unified genetic theory for sporadic and inherited autism. (2002). The mean T-score of this group of 78 individuals was 77.13 (SD = 15.91) and 65 participants (83.33 %) met clinical cut-off for behavioural symptomatology associated with ASD (Fig. Sotos syndrome is caused by intragenic mutations or microdeletions of the NSD1 gene, resulting in loss of function and it has been suggested that abnormalities of the NSD1 gene are present in more than 90 % of individuals with a clinical diagnosis of Sotos syndrome (Tatton-Brown et al. An additional benefit of the SRS-2 is that, by providing T-scores, it is possible to compare data from males and females and from different age groups. Women with Sotos syndrome are just as likely to show signs of autism as men with the syndrome, and there is no difference in the severity of features between the two genders. Overall, these findings indicate that the majority of individuals with Sotos syndrome display clinically significant behavioural symptomatology associated with ASD. Excessive growth often starts in infancy and continues into the early teen years. (2015). In e, scores in the severe range were reported in 3 individuals (23.08 %). Fombonne, E. (2009). Additionally, Trad et al. University of Birmingham, Birmingham. Assessing autistic traits: Cross-cultural validation of the social responsiveness scale (SRS). Tatton-Brown, K., Douglas, J., Coleman, K., Baujat, G., Cole, T. R. P., Das, S., et al. The Lancet Psychiatry, 2(10), 909–916. Sotos syndrome Support Association (SSSA) is made up of families, physicians, genetic counselors, and health care agencies throughout the United States. Lane, C., Milne, E., & Freeth, M. (2016). position Sotos syndrome relative to other groups in which the associated behavioural characteristics are well described. The SRS-2 is a 65-item questionnaire with each item being coded on a Likert scale (0 = not true to 3 = almost always true), designed to assess symptoms associated with ASD. - 104.131.34.188. This study investigated behavioural characteristics of ASD within a large cohort of individuals with Sotos syndrome (n = 78). Some children with Sotos syndrome have autism, while others have only mild to moderate learning disabilities. In d, scores in the severe range were reported in 8 individuals (80 %). 1 thank. Scores are categorised as non-clinical, or as indicative of mild, moderate or severe issues with reciprocal social interaction. Journal of Autism and Developmental Disorders, 30(3), 205–223. Autistic features were assessed using The social responsiveness scale (SRS) (Constantino and Gruber 2005) which provides a quantitative measure of ASD symptomatology. Sotos syndrome is a congenital overgrowth disorder with an incidence of approximately 1 in 14,000. All respondents were asked to complete a screening form, in order to establish eligibility for the study. A 2 × 5 (Sotos/ASD × SRS subscale) mixed measures ANOVA found no main effect of diagnosis, (F(1,315) = 0.62, p = .43). Sotos syndrome—a study of the diagnostic criteria and natural history. The findings from this study suggest that each of the disorder groups displayed a trait profile similar to that of ASD, specifically in relation to difficulties in social cognition and repetitive mannerisms, but at a lower severity level. 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. Symptom severity does not appear to be affected by gender but does seem to differ in relation to age, with more prominent behavioural characteristics in childhood (5–19 years), compared with early childhood (2.5–5 years) and adulthood (20 years and older).

This includes having a head that is longer and wider than normal and a pointed chin. 2016; Sheth et al. The RBQ is a 19-item questionnaire, designed to assess behaviours across five subscales: restricted preferences, repetitive speech, insistence on sameness, stereotyped behaviour and compulsive behaviour. 2006; Baron-Cohen et al. autism awareness, autism spectrum disorder, autism therapy kerala, ... Sotos syndrome is a genetic disorder caused by the mutation of gene NSD1. Sotos syndrome is a rare genetic disorder characterized by excessive physical growth during the first years of life. The numbers represent total number of participants in each category. Autism spectrum disorder in fragile X syndrome: Communication, social interaction, and specific behaviors. The NSD1 and EZH2 overgrowth genes, similarities and differences. As measured by the Social Responsiveness Scale, second edition (SRS-2), 65 participants (83.33 %) met clinical cut-off (T-score ≥60). Furthermore, distinct ASD phenotypes may be associated with each genetic syndrome (Moss and Howlin 2009). 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). Journal of Child Psychology and Psychiatry, 53(8), 883–891. ASD was not mentioned in the study information, in order to avoid biasing the sample. Although children with Sotos syndrome had difficulty with both ASD subscales, participants had significantly greater impairment with social relations, compared with restricted interests. In order to establish whether gender affects ASD symptom severity within the Sotos population, an independent samples t test was used to compare total T-scores in male and female participants. If an individual receives one normal gene and one abnormal variant gene for the disease, the person will be a carrier for the disease, but usually will not show symptoms. [] who observed five patients with similar clinical features.These included excessively rapid growth, acromegalic features and a non-progressive cerebral disorder with mental retardation. We are extremely grateful to all of the families who took part in this research study. 2000) and a matched control group of individuals with ASD. In order to investigate whether there were particular difficulties observed in either of the two DSM-5 domains, a paired-samples t test was used to compare scores on each of these subscales. CL conceived of the study, participated in the design, performed the data collection and subsequent statistical analyses and drafted the manuscript; EM conceived of the study, participated in the design and interpretation of the data and contributed to writing the manuscript; MF conceived of the study, participated in the design and interpretation of the data and contributed to writing the manuscript. A 32-year-old member asked: is asperger's syndrome a type of autism? PubMed Central  Affected infants and children with Sotos grow quicker than other children their age. However, it is clear from the findings in the present study that autistic symptomatology may be more prevalent in Sotos syndrome than many other genetic syndromes. sotos syndrome autism. Send thanks to the doctor. Morrow, J. D., Whitman, B. Y., & Accardo, P. J. Google Scholar. The social responsiveness scale (2nd ed.). There are three SCQ subscales (reciprocal social interaction; communication; restricted, repetitive and stereotyped patterns of behaviour) which are based on the DSM-IV criteria for ASD. These individuals show restricted interests, compulsive behaviors, repetitive speech, social anxiety and reliance on routine. 2014). We are also very thankful to the Child Growth Foundation for providing funding to support this research. The study identified a significant association between ASD and Sotos syndrome. Specifically, this analysis identified that the model of best fit was quadratic (F(4,77) = 15.98, p < .001), indicating an inverted U-shaped pattern of total T-scores. The disorder occurs in approximately 1 % of the population (Baird et al. Sotos syndrome is an autosomal dominant disorder caused by mutations in the NSD1 gene with an incidence of approximately 1:14,000. 3 doctors agree. 2014). Most people with Sotos syndrome show signs of autism, according to the largest-yet study of people with the rare genetic condition 1. A recent confirmatory factor analysis (Frazier et al. 2005). 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.
