Several lines of evidence point towards the presence of shared genetic factors underlying ASD and ADHD. We conducted genomic analyses of common risk variants (i.e. single nucleotide polymorphisms, SNPs) shared by ASD and ADHD, and those specific to each disorder. METHODS: With the summary data from two GWAS, one on ASD (N = 46,350) and another on ADHD (N = 55,374) individuals, we used genomic structural equation modelling and colocalization analysis to identify SNPs shared by ASD and ADHD and SNPs specific to each disorder. Functional genomic analyses were then conducted on shared and specific common genetic variants. Finally, we performed a bidirectional Mendelian randomization analysis to test whether the shared genetic risk between ASD and ADHD was interpretable in terms of reciprocal relationships between ASD and ADHD. RESULTS: We found that 37.5% of the SNPs associated with ASD (at p < 1e-6) colocalized with ADHD SNPs and that 19.6% of the SNPs associated with ADHD colocalized with ASD SNPs. We identified genes mapped to SNPs that are specific to ASD or ADHD and that are shared by ASD and ADHD, including two novel genes INSM1 and PAX1. Our bidirectional Mendelian randomization analyses indicated that the risk of ASD was associated with an increased risk of ADHD and vice versa. CONCLUSIONS: Using multivariate genomic analyses, the present study uncovers shared and specific genetic variants associated with ASD and ADHD. Further functional investigation of genes mapped to those shared variants may help identify pathophysiological pathways and new targets for treatment.

Improving the early screening procedure for autism spectrum disorder in young children: Experience from a community-based model in shanghai / C. LI in Autism Research, 11-9 (September 2018)

XU, Auteur Article en page(s) : p.1206-1217 Langues : Anglais (eng) Mots-clés : Chat-23  China  autism spectrum disorder  community-based  early screening Index. décimale : PER Périodiques Résumé : Most children with autism spectrum disorder (ASD) are not diagnosed until the age of 4, thus missing the opportunity for early intervention. The objective of this study was to investigate the feasibility of an early screening program for ASD applied during well-child visits in a community-based sample. The study lasted for 4 years and was divided into two stages. Stage I involved the implementation of the basic screening model in 2014. Toddlers received level 1 screening via section A of the Chinese-validated version of the Checklist for Autism in Toddlers (CHAT-23) during 18- and 24-month well-child visits in Xuhui District, Shanghai, China. Screen-positive children were referred to receive section B of the CHAT-23 for level 2 screening, and those still screen-positive were referred to undergo diagnosis and evaluation. Stage II involved the implementation of the improved screening model from 2015 to 2017 with the following modifications: (a) an added observational component in level 1 screening; (b) telephone follow-ups with the screen-positive families; and (c) dissemination of information on ASD to families. The results showed that 42 of 22,247 screened children were diagnosed with ASD. The ASD diagnosis rates were 0.1% in Stage I and 0.21% in Stage II. The screen-positive rate and the show rate of referral for level 1 screening increased by 76.92% and 58.43%, respectively, in Stage II compared to Stage I. Our results suggest that with appropriate logistic support, this two-level screening model is feasible and effective for the early screening of ASD during well-child visits. Autism Res 2018, 11: 1206-1217. (c) 2018 International Society for Autism Research, Wiley Periodicals, Inc. LAY SUMMARY: Difficulty in the timely identification of autism spectrum disorder (ASD) results in missed opportunities for many ASD children to receive early intervention. In this study, we established an early screening model for ASD among children aged 18-24 months in the community by relying on the three-level child healthcare system in China. The results showed that this model can effectively identify and diagnose ASD in children at an early age and thus enable early intervention.

Psychiatric Comorbidities and Psychotropic Medication Use in Autism: A Matched Cohort Study with ADHD and General Population Comparator Groups in the United Kingdom / R. HOUGHTON in Autism Research, 11-12 (December 2018)

HOUGHTON, Auteur ; C. LIU, Auteur ; Federico BOLOGNANI, Auteur Article en page(s) : p.1690-1700 Langues : Anglais (eng) Mots-clés : United Kingdom  attention deficit hyperactivity disorder  autism spectrum disorder  electronic medical records  polypharmacy  psychiatric comorbidities  psychotropic medications Index. décimale : PER Périodiques Résumé : Psychiatric comorbidities and use of psychotropic medications are common among patients with autism spectrum disorder (ASD). However, most previous research used data from the United States (US) and few studies have compared medication use in ASD to control groups, making contextualization of results difficult. In the United Kingdom (UK), general practitioners play a key role in the management of ASD. We conducted a retrospective, cross-sectional study over calendar year 2015, using primary care data from the UK. We identified a prevalent cohort of ASD cases (n = 10,856) and matched control groups of (a) general population (n = 21,712) and (b) attention deficit hyperactivity disorder (ADHD; n = 7,058) on age, sex and region. We described psychiatric comorbidities, psychotropic medications, and healthcare utilization in all three cohorts. Within the ASD cohort, we used multivariable logistic regression models to explore associations between patient characteristics and the outcomes of: any psychotropic medication, polypharmacy, and number of primary care visits. We used conditional logistic regression to compare the ASD and control groups. Psychiatric comorbidities were recorded for 41.5% of ASD patients; 32.3% received psychotropic medication and 9.8% received polypharmacy. Increased age and all psychiatric comorbidities (except conduct disorder) were associated with treatment use. Males were less likely to receive a treatment than females [Odds ratio (OR) 0.74 (0.66-0.83)]. ASD patients were more likely to take psychotropic medications than the general population [OR 4.91 (4.46-5.40)], but less likely compared to ADHD patients [OR 0.40 (0.37-0.44)]. Overall, rates of medication use in the UK were lower than those previously reported in the US. Autism Research 2018, 11: 1690-1700. (c) 2018 International Society for Autism Research, Wiley Periodicals, Inc. LAY SUMMARY: We used electronic medical records from the UK, to describe the amount of psychiatric comorbidities, psychotropic medication use and healthcare resource use in ASD. Around one in three people with ASD were prescribed a psychotropic medication, which was more than the general population, but less than for those with ADHD. Increased age, psychiatric comorbidities and female gender were all independently associated with psychotropic medication use. Rates of medication use in the UK were lower than those previously reported in the US.

The role of child negative emotionality in parenting and child adjustment: Gene-environment interplay / E. A. SHEWARK in Journal of Child Psychology and Psychiatry, 62-12 (December 2021)

The current study examined whether heritable influences on parenting and children's behavioural outcomes operate through child negative emotionality. METHOD: Using data from the Early Growth and Development Study, we examined associations among adoptive parent reports of child anger and sadness at 4.5?years, adoptive parents' hostile and warm parenting at 6?years and child behavioural problems and social competence at age 7. Birth parent temperament was included to test whether child effects on parents reflect evocative gene-environment correlation (rGE). RESULTS: Child anger at 4.5?years evoked hostile parenting from adoptive parents at 6?years, which was subsequently related to child problem behaviours at 7?years. Evocative rGE effects were identified for adoptive parents' hostile parenting. CONCLUSIONS: By employing a genetically informed design, we found that birth parent temperament was related to child negative emotionality. Adoptive parents were sensitive to child negative emotionality, and this sensitivity was linked to the child's later adjustment.
