ASD Comorbidity in Fragile X Syndrome: Symptom Profile and Predictors of Symptom Severity in Adolescent and Young Adult Males / Leonard ABBEDUTO in Journal of Autism and Developmental Disorders, 49-3 (March 2019)
[article]
Titre : ASD Comorbidity in Fragile X Syndrome: Symptom Profile and Predictors of Symptom Severity in Adolescent and Young Adult Males Type de document : Texte imprimé et/ou numérique Auteurs : Leonard ABBEDUTO, Auteur ; A. J. THURMAN, Auteur ; A. MCDUFFIE, Auteur ; J. KLUSEK, Auteur ; R. T. FEIGLES, Auteur ; W. Ted BROWN, Auteur ; D. J. HARVEY, Auteur ; T. ADAYEV, Auteur ; G. LAFAUCI, Auteur ; C. DOBKINS, Auteur ; J. E. ROBERTS, Auteur Article en page(s) : p.960-977 Langues : Anglais (eng) Mots-clés : Autism spectrum disorder Fmrp Fragile X syndrome Iq Language Psychiatric symptoms Index. décimale : PER Périodiques Résumé : Many males with FXS meet criteria for ASD. This study was designed to (1) describe ASD symptoms in adolescent and young adult males with FXS (n = 44) and (2) evaluate the contributions to ASD severity of cognitive, language, and psychiatric factors, as well as FMRP (the protein deficient in FXS). A few ASD symptoms on the ADOS-2 were universal in the sample. There was less impairment in restricted and repetitive behaviors (RRB) than in the social affective (SA) domain. The best predictor of overall ASD severity and SA severity was expressive syntactic ability. RRB severity was best predicted by the psychiatric factors. Implications for clinical practice and for understanding the ASD comorbidity in FXS are discussed.

Titre : Reduced vagal tone in women with the FMR1 premutation is associated with FMR1 mRNA but not depression or anxiety Type de document : Texte imprimé et/ou numérique Auteurs : J. KLUSEK, Auteur ; G. LAFAUCI, Auteur ; T. ADAYEV, Auteur ; W. Ted BROWN, Auteur ; F. TASSONE, Auteur ; J. E. ROBERTS, Auteur Article en page(s) : p.16 Langues : Anglais (eng) Mots-clés : FMR1 mRNA Fmrp Fragile X carriers Heart rate Physiological arousal Vagal tone Index. décimale : PER Périodiques Résumé : BACKGROUND: Autonomic dysfunction is implicated in a range of psychological conditions, including depression and anxiety. The fragile X mental retardation-1 (FMR1) premutation is a common genetic mutation that affects ~1:150 women and is associated with psychological vulnerability. This study examined cardiac indicators of autonomic function among women with the FMR1 premutation and control women as potential biomarkers for psychological risk that may be linked to FMR1. METHODS: Baseline inter-beat interval and respiratory sinus arrhythmia (a measure of parasympathetic vagal tone) were measured in 35 women with the FMR1 premutation and 28 controls. The women completed anxiety and depression questionnaires. FMR1 genetic indices (i.e., CGG repeat, quantitative FMRP, FMR1 mRNA, activation ratio) were obtained for the premutation group. RESULTS: Respiratory sinus arrhythmia was reduced in the FMR1 premutation group relative to controls. While depression symptoms were associated with reduced respiratory sinus arrhythmia among control women, these variables were unrelated in the FMR1 premutation. Elevated FMR1 mRNA was associated with higher respiratory sinus arrhythmia. CONCLUSIONS: Women with the FMR1 premutation demonstrated autonomic dysregulation characterized by reduced vagal tone. Unlike patterns observed in the general population and in study controls, vagal activity and depression symptoms were decoupled in women with the FMR1 premutation, suggesting independence between autonomic regulation and psychopathological symptoms that is atypical and potentially specific to the FMR1 premutation. The association between vagal tone and mRNA suggests that molecular variation associated with FMR1 plays a role in autonomic regulation.
