AbstractSocial impairments are common features of 22q11.2 deletion syndrome (22q11DS) and autism spectrum disorders (ASD). The Ecological Momentary Assessment (EMA) allowed access to daily-life information in order to explore the phenomenology of social interactions. 32 individuals with 22q11DS, 26 individuals with ASD and 44 typically developing peers (TD) aged 12–30 were assessed during 6 days 8 times a day using a mobile app. Participants with 22q11DS and ASD did not spend more time alone but showed distinct implication in the social sphere than TD. Distinct profiles emerged between the two conditions regarding the subjective experience of aloneness and the subjective experience of social interactions. This study highlights distinct social functioning profiles in daily-life in 22q11DS and ASD that points towards different therapeutic targets.

Abstract Background: Social impairments are common features of several neurodevelopmental conditions, including 22q11.2 deletion syndrome (22q11DS) and autism spectrum disorders (ASD). However, little is known about social interactions in daily-life. The Ecological Momentary Assessment (EMA) was used to have access to daily-life information and to distinguish the phenomenology of social interactions between the two conditions, often considered as presenting a similar profile of social impairments.Methods: 32 individuals with 22q11DS, 26 individuals with ASD and 44 healthy controls (HC) aged 12-30 were recruited. All participants were assessed during 6 days 8 times a day using a mobile app. The EMA protocol assessed positive and negative affect, social context (alone versus in company) and the subjective experience of aloneness and social interactions.Results: Participants with 22q11DS and ASD did not spend more time alone, but spent less time with familiar individuals such as friends, and more time with people they live with, compared to HC. However, distinct profiles emerged between the two conditions regarding the subjective experience of aloneness, with more intense feelings of exclusion in participants with ASD compared to participants with 22q11DS and HC. The subjective appreciation of interactions revealed that individuals with ASD felt more judged and more nervous than both 22q11DS and HC. Nevertheless, both conditions expressed a higher desire to be alone when in company of other people than HC.Conclusions: This study highlights distinct social functioning profiles in daily-life in 22q11DS and ASD, giving new intel regarding the social phenotype in these conditions, and pointing towards different therapeutic targets.

Over Time

This study investigated three conversational subskills in children with 22q11.2 deletion syndrome (22q11.2DS, n = 8, ages 7–13) and Williams syndrome (WS, n = 8, ages 6–12). The researchers re-evaluated these subskills after 18 to 24 months and compared them to those of peers with idiopathic intellectual disability (IID) and IID and comorbid autism spectrum disorders (IID+ASD). Children with 22q11.2DS became less actively involved over time. Lower assertiveness than in children with IID was demonstrated. They seemed less impaired in terms of accounting for listener’s knowledge than children with IID+ASD. Children with WS showed greater difficulties with discourse management compared to children with IID and 22q11.2DS. They had similar levels of conversational impairments to children with IID+ASD but these were caused by different shortcomings. Over time taking account of listener’s knowledge became challenging for them. Findings suggest that children with 22q11.2DS and those with WS would benefit from conversational skills support and that regular re-evaluation is needed to anticipate conversational challenges.

AbstractPurpose of ReviewThe 22q11.2 deletion syndrome (22q11DS) is associated with a broad spectrum of neurodevelopmental phenotypes and is the strongest known single genetic risk factor for schizophrenia. Compared to other rare structural pathogenic genetic variants, 22q11DS is relatively common and one of the most extensively studied. This review provides a state-of-the-art overview of current insights regarding associated neurodevelopmental phenotypes and potential implications for 22q11DS and beyond.Recent FindingsWe will first discuss recent findings with respect to neurodevelopmental phenotypic expression associated with 22q11DS, including psychotic disorders, intellectual functioning, autism spectrum disorders, as well as their interactions. Second, we will address considerations that are important in interpreting these data and propose potential implications for both the clinical care for and the empirical study of individuals with 22q11DS. Third, we will highlight variable penetrance and pleiotropy with respect to neurodevelopmental phenotypes in 22q11DS. We will discuss how these phenomena are consistently observed in the context of virtually all rare pathogenic variants and that they pose substantial challenges from both a clinical and a research perspective.SummaryWe outline how 22q11DS could be viewed as a genetic model for studying neurodevelopmental phenotypes. In addition, we propose that 22q11DS research can help elucidate mechanisms underlying variable expression and pleiotropy of neurodevelopmental phenotypes, insights that are likely relevant for 22q11DS and beyond, including for individuals with other rare pathogenic genetic variants and for individuals with idiopathic neurodevelopmental conditions.

Duplication Syndrome

22q11.2 duplication syndrome is a recently discovered genetic syndrome with unclear neuropsychiatric sequelae. While its connection to 22q11.2 deletion syndrome is actively investigated, case reports on the neuropsychiatric sequelae of affected individuals have been previously described, largely focusing on comorbid autism spectrum disorder. Here, we present the case of an 8-year-old female experiencing episodes of severe behavioural regression following medical illness. We analyze the case and relate it to the available literature and identify potential risk factors.

Coordination Disorder

Background22q11.2 deletion syndrome (22q11.2DS) is associated with high rates of neurodevelopmental disorder, however, the links between developmental coordination disorder (DCD), intellectual function and psychiatric disorder remain unexplored.AimsTo establish the prevalence of indicative DCD in children with 22q11.2DS and examine associations with IQ, neurocognition and psychopathology.MethodNeurocognitive assessments and psychiatric interviews of 70 children with 22q11.2DS (mean age 11.2, s.d. = 2.2) and 32 control siblings (mean age 11.5, s.d. = 2.1) were carried out in their homes. Nine children with 22q11.2DS and indicative DCD were subsequently assessed in an occupational therapy clinic.ResultsIndicative DCD was found in 57 (81.4%) children with 22q11.2DS compared with 2 (6.3%) control siblings (odds ratio (OR) = 36.7,P< 0.001). Eight of nine (89%) children with indicative DCD met DSM-5 criteria for DCD. Poorer coordination was associated with increased numbers of anxiety, (P< 0.001), attention-deficit hyperactivity disorder (ADHD) (P< 0.001) and autism-spectrum disorder (ASD) symptoms (P< 0.001) in children with 22q11.2DS. Furthermore, 100% of children with 22q11.2DS and ADHD had indicative DCD (20 of 20), as did 90% of children with anxiety disorder (17 of 19) and 96% of children who screened positive for ASD (22 of 23). The Developmental Coordination Disorder Questionnaire score was related to sustained attention (P= 0.006), even after history of epileptic fits (P= 0.006) and heart problems (P= 0.009) was taken into account.ConclusionsClinicians should be aware of the high risk of coordination difficulties in children with 22q11.2DS and its association with risk of mental disorder and specific neurocognitive deficits.Declaration of interestNone.

Common Deletion

IntroductionThe 22q11.2 deletion syndrome (22q11DS), mostly caused by the common deletion including the TBX- and COMT-genes (LCR22A-D), is highly associated with somatic anomalies. The distal deletion (distal of LCR22D) comprises the MAPK1-gene and is associated with specific heart defects. The rare central deletion (LCR22B-D) encompasses the CRKL-gene and shows predominantly urogenital anomalies. 22q11DS also differs in its neuropsychiatric profile: common deletion accompanied by schizophrenia-like psychoses and autism spectrum disorders, distal deletion by anxiety disorders, and central deletion by autistic-like behaviours.ObjectivesInvestigating genetic subtypes of 22q11DS.AimsAchieving a targeted pharmacological treatment based on genetic sub-typing.MethodsThirty-two patients with genetically proven 22q11DS, referred for detailed neuropsychiatric analysis.ResultsApart from two patients with distal deletion and one with central deletion, common 22q11.2 deletion was detected in 29 patients. Those with the common deletion were typified by a history of relapsing schizophrenia-like psychoses and partial non-response to conventional antipsychotics. In most patients, anxieties and mood instability were also manifest. The two patients with a distal deletion predominantly showed anxiety symptoms, while the behaviour of the patient with a central deletion was characterized by symptoms from the autism spectrum. Most patients with a common deletion could successfully be treated with clozapine or quetiapine, often combined with valproic acid. One patient with a distal deletion showed full remission upon treatment with citalopram (the second refused such a pharmacological intervention). The behaviour of the patient with central deletion improved upon contextual measures only.ConclusionsThe genetic subtype of 22q11DS enables targeting of treatment strategy.Disclosure of interestThe authors have not supplied their declaration of competing interest.
