Previous attempts to associate CNTN5 CNVs with ASD-susceptibility were limited by insufficient statistical power. Here, we aim to clarify the putative association between CNTN5 CNVs and ASD-risk using large-scale case-control analyses. Method A CNTN5 CNV, shared by four brothers in a multiplex family with ASD, was initially identified. We calculated the prevalence and transmission of CNTN5 CNVs in cases across five ASD cohorts (n=15,784). Second, we compared the prevalence of CNTN5 CNVs in cases to their unaffected siblings (n=4,996). Third, we assessed the enrichment of CNTN5 CNVs in cases to extrafamilial controls across three cohorts (n=24,886) and the UK Biobank (n = 459,862). Finally, we evaluated the clinical impact of CNTN5 CNVs in a broad neurodevelopmental disorder cohort and the DECIPHER database. Results Most (96.7%) CNTN5 CNV deletions (0.193%) and duplications (0.03%) in cases were inherited by a parent that transmitted the variant to their affected and unaffected children at the same rate. We identified a significant enrichment of intronic CNTN5 CNV deletions in cases compared to extrafamilial controls (0.178% versus 0.019%; p-value=1.68E-05; OR:8.51; 95%CI=[2.58-44.21]). There was no difference in CNTN5 CNV enrichment between cases and individuals with NDDs. Conclusions Intronic CNTN5 CNV deletions are rare, inherited, and intermediate effect size ASD-susceptibility variants that may also confer risk for other neuropsychiatric disorders. We offer a framework to characterize candidate variants that may not be detected through small-scale approaches to implicate intermediate effect size variants in the etiology of ASD.

In this study, we test the hypothesis that manic symptoms in youth separate along two correlated dimensions and that a symptom constellation of high energy and cheerfulness is associated with superior cognitive performance. Method We studied 1755 participants of the IMAGEN study, of average age 14.4 years (SD = 0.43), 50.7% girls. Manic symptoms were assessed using the Development and Wellbeing Assessment by interviewing parents and young people. Cognition was assessed using the Wechsler Intelligence Scale For Children (WISC-IV) and a response inhibition task. Results Manic symptoms in youth formed two correlated dimensions: one termed exuberance, characterized by high energy and cheerfulness and one of undercontrol with distractibility, irritability and risk-taking behavior. Only the undercontrol, but not the exuberant dimension, was independently associated with measures of psychosocial impairment. In multivariate regression models, the exuberant, but not the undercontrolled, dimension was positively and significantly associated with verbal IQ by both parent- and self-report; conversely, the undercontrolled, but not the exuberant, dimension was associated with poor performance in a response inhibition task. Conclusions Our findings suggest that manic symptoms in youth may form dimensions with distinct correlates. The results are in keeping with previous findings about superior performance associated with mania. Further research is required to study etiological differences between these symptom dimensions and their implications for clinical practice.

Disrupted Functional Connectivity in Dorsal and Ventral Attention Networks During Attention Orienting in Autism Spectrum Disorders / Jacqueline FITZGERALD in Autism Research, 8-2 (April 2015)  

Public ISBD [article]  inAutism Research > 8-2 (April 2015) . - p.136-152 Titre : Disrupted Functional Connectivity in Dorsal and Ventral Attention Networks During Attention Orienting in Autism Spectrum Disorders Type de document : texte imprimé Auteurs : Jacqueline FITZGERALD, Auteur ; Katherine JOHNSON, Auteur ; Elizabeth KEHOE, Auteur ; Arun L. W. BOKDE, Auteur ; Hugh GARAVAN, Auteur ; Louise GALLAGHER, Auteur ; Jane MCGRATH, Auteur Article en page(s) : p.136-152 Langues : Anglais (eng) Mots-clés : autism spectrum disorders  functional connectivity  attention orienting  attention network  neuroimaging Index. décimale : PER Périodiques Résumé : Background Attention orienting is a cognitive process that facilitates the movement of attention focus from one location to another: this may be impaired in autism spectrum disorder (ASD). Dorsal and ventral attention networks (DAN and VAN) sub-serve the process of attention orienting. This study investigated the functional connectivity of attention orienting in these networks in ASD using the Posner Cueing Task. Method Twenty-one adolescents with ASD and 21 age and IQ matched controls underwent functional magnetic resonance imaging. A psychophysical interaction (PPI) analysis was implemented to investigate task-dependent functional connectivity, measuring synchronicity of brain regions during the task. Regions of interest (ROI) were selected to explore functional connectivity in the DAN during cue-only conditions and in the VAN during invalid and valid trials. Results Behaviourally, the ASD and control groups performed the task in a similar manner. Functional MRI results indicated that the ASD and control groups activated similar brain regions. During invalid trials (VAN), the ASD group showed significant positive functional connectivity to multiple brain regions, whilst the control group demonstrated negative connectivity. During valid trials (VAN), the two groups also showed contrasting patterns of connectivity. In the cue-only conditions (DAN), the ASD group showed weaker functional connectivity. Conclusion The DAN analysis suggests that the ASD group has weaker coherence between brain areas involved in goal-driven, endogenous attention control. The strong positive functional connectivity exhibited by the ASD group in the VAN during the invalid trials suggests that individuals with ASD may generate compensatory mechanisms to achieve neurotypical behaviour. These results support the theory of abnormal cortical connectivity in autism.

In a genome-wide methylation analysis, we recently identified an association of a methylated region in the OPRL1 gene with alcohol-use disorders. METHODS: Here, we investigate the biological basis of this observation by analysing psychosocial stressors, methylation of the OPRL1 gene, brain response during reward anticipation and alcohol drinking in 660 fourteen-year-old adolescents of the IMAGEN study. We validate our findings in marchigian sardinian (msP) alcohol-preferring rats that are genetically selected for increased alcohol drinking and stress sensitivity. RESULTS: We found that low methylation levels in intron 1 of OPRL1 are associated with higher psychosocial stress and higher frequency of binge drinking, an effect mediated by OPRL1 methylation. In individuals with low methylation of OPRL1, frequency of binge drinking is associated with stronger BOLD response in the ventral striatum during reward anticipation. In msP rats, we found that stress results in increased alcohol intake and decreased methylation of OPRL1 in the nucleus accumbens. CONCLUSIONS: Our findings describe an epigenetic mechanism that helps to explain how psychosocial stress influences risky alcohol consumption and reward processing, thus contributing to the elucidation of biological mechanisms underlying risk for substance abuse.

Results The interaction of competence and adversity identified two regions centered on the right middle and superior frontal gyri; grey matter volumes in these regions were larger in adolescents experiencing adversity who showed positive adaptation. Differences in these regions among competence/adversity subgroups were maintained after controlling for several covariates and were robust to alternative operationalization decisions for key constructs. Conclusions We demonstrate structural brain correlates of adolescent resilience, and suggest that right prefrontal structures are implicated in adaptive functioning for youth who have experienced adversity.
