A genetic overlap has been shown between ALTs and ASD, indicating that common variation in ASD candidate genes may also influence ALTs. In our study, we have investigated the SNP rs4307059 that has been associated with both ALTs and ASD. In addition, we genotyped polymorphisms in a selection of genes involved in synaptic functioning, that is, SHANK3, RELN, and CNTNAP2, which repeatedly have been associated with ASD. The possible associations of these polymorphisms with ALTs, as well as genetic factors for neurodevelopmental problems (NDPs), were investigated in a large cohort from the general population: The Child and Adolescent Twin Study in Sweden. For analyses of ALTs and NDPs, 12,319 subjects (including 2,268 monozygotic (MZ) and 3,805 dizygotic (DZ) twin pairs) and 8,671 subjects (including 2,243 MZ and 2,044 DZ twin pairs), respectively, were included in the analyses.

Autism and emotional face-viewing / Jakob ÅSBERG JOHNELS in Autism Research, 10-5 (May 2017)  

Public ISBD [article]  inAutism Research > 10-5 (May 2017) . - p.901-910 Titre : Autism and emotional face-viewing Type de document : Texte imprimé et/ou numérique Auteurs : Jakob ÅSBERG JOHNELS, Auteur ; Daniel HOVEY, Auteur ; Nicole ZÜRCHER, Auteur ; Loyse HIPPOLYTE, Auteur ; Eric LEMONNIER, Auteur ; Christopher GILLBERG, Auteur ; Nouchine HADJIKHANI, Auteur Article en page(s) : p.901-910 Langues : Anglais (eng) Mots-clés : autism  eye-tracking  mouth  face  autism quotient  social  endophenotype Index. décimale : PER Périodiques Résumé : Atypical patterns of face-scanning in individuals with autism spectrum disorder (ASD) may contribute to difficulties in social interactions, but there is little agreement regarding what exactly characterizes face-viewing in ASD. In addition, little research has examined how face-viewing is modulated by the emotional expression of the stimuli, in individuals with or without ASD. We used eye-tracking to explore viewing patterns during perception of dynamic emotional facial expressions in relatively large groups of individuals with (n?=?57) and without ASD (n?=?58) and examined diagnostic- and age-related effects, after subgrouping children and adolescents (?18 years), on the one hand, and adults (>18 years), on the other. Results showed that children/adolescents with ASD fixated the mouth of happy and angry faces less than their typically developing (TD) peers, and conversely looked more to the eyes of happy faces. Moreover, while all groups fixated the mouth in happy faces more than in other expressions, children/adolescents with ASD did relatively less so. Correlation analysis showed a similar lack of relative orientation towards the mouth of smiling faces in TD children/adolescents with high autistic traits, as measured by the Autism-Spectrum Quotient (AQ). Among adults, participants with ASD only attended less to the eyes for neutral faces. Our study shows that the emotional content of a face influences gaze behaviour, and that this effect is not fully developed in children/adolescents with ASD. Interestingly, this lack of differentiation observed in the younger ASD group was also seen in younger TD individuals with higher AQ scores.
