Autism Spectrum Disorder, Developmental and Psychiatric Features in 16p11.2 Duplication / LeeAnne GREEN SNYDER in Journal of Autism and Developmental Disorders, 46-8 (August 2016)

Quantitative ASD, behavioral and neuropsychological measures and DSM-IV diagnoses in child and adult carriers were compared with familial non-carrier controls, and to published results from deletion carriers. The 16p11.2 duplication phenotype ranges widely from asymptomatic presentation to significant disability. The most common diagnoses were intellectual disability, motor delays and Attention Deficit Hyperactivity Disorder in children, and anxiety in adults. ASD occurred in nearly 20 % of child cases, but a majority of carriers did not show the unique social features of ASD. The 16p11.2 duplication phenotype is characterized by wider variability than the reciprocal deletion, likely reflecting contributions from additional risk factors.

Autism spectrum disorders (ASD) and intellectual disability (ID) are genetically heterogeneous, and novel genes for these disorders are rapidly being identified, making these disorders ideal candidates for WES. Here we report a 17-year-old girl with ASD, developmental delay, ID, seizures, Chiari I malformation, macrocephaly, and short stature. She was found by WES to have a de novo c.2028delT (P677LfsX19) mutation in the SET domain-containing protein 2 (SETD2) gene, predicted to be gene-damaging. This case offers evidence for the potential the role of SETD2 in ASD and ID and provides further detail about the phenotypic manifestations of mutations in SETD2.

Titre : Evaluating heterogeneity in ASD symptomatology, cognitive ability, and adaptive functioning among 16p11.2 CNV carriers Type de document : Texte imprimé et/ou numérique Auteurs : Caitlin M.

Although autism spectrum disorder (ASD) is reported in approximately 20-23% of individuals with 16p11.2 CNVs, ASD-associated symptoms are observed in those without a clinical ASD diagnosis. Previous work has shown that genetic variation and prenatal and perinatal birth complications influence ASD risk and symptom severity. This study examined the impact of genetic and environmental risk factors on phenotypic heterogeneity among 16p11.2 CNV carriers. Participants included individuals with a 16p11.2 deletion (N = 96) or duplication (N = 77) with exome sequencing from the Simons VIP study. The presence of prenatal factors, perinatal events, additional genetic events, and gender was studied. Regression analyses examined the contribution of each risk factor on ASD symptomatology, cognitive functioning, and adaptive abilities. For deletion carriers, perinatal and additional genetic events were associated with increased ASD symptomatology and decrements in cognitive and adaptive functioning. For duplication carriers, secondary genetic events were associated with greater cognitive impairments. Being female sex was a protective factor for both deletion and duplication carriers. Our findings suggest that ASD-associated risk factors contribute to the variability in symptom presentation in individuals with 16p11.2 CNVs. LAY SUMMARY: There are a wide range of autism spectrum disorder (ASD) symptoms and abilities observed for individuals with genetic changes of the 16p11.2 region. Here, we found perinatal complications contributed to more severe ASD symptoms (deletion carriers) and additional genetic mutations contributed to decreased cognitive abilities (deletion and duplication carriers). A potential protective factor was also observed for females with 16p11.2 variations. Autism Res 2020, 13: 1300-1310. © 2020 International Society for Autism Research, Wiley Periodicals, Inc.

Participants were 78.4% male, 47.3% had intellectual disability, and 32.1% had persistent language impairments. Childhood language disorders (59.7%), speech/articulation problems (32.8%), sleep (39.4%) and eating problems (29.4%), motor delays (22.8%) and history of seizure (15.5%) were the most frequently reported clinical features. Over two thirds (67.2%) had been diagnosed with at least one psychiatric disorder (anxiety disorders: 41.1%; ADHD: 38.7%). Compared to verbally fluent participants, those with language impairments had lower frequencies of almost all psychiatric disorders. Female sex and older age were associated with higher medical and psychiatric morbidity.

Blake TURNER, Auteur ; LeeAnne GREEN SNYDER, Auteur ; Wendy K. CHUNG, Auteur ; Jeremy VEENSTRA-VANDERWEELE, Auteur Article en page(s) : p.187-198 Langues : Anglais (eng) Mots-clés : autism spectrum disorder chromosome deletion chromosome duplication chromosomes human obsessive-compulsive disorder pair 16 phenotype schizophrenia spectrum and other psychotic disorders Index. décimale : PER Périodiques Résumé : 16p11.2 copy-number variation (CNV) is implicated in neurodevelopmental disorders, with the duplication and deletion associated with autism spectrum disorder (ASD) and the duplication associated with schizophrenia (SCZ). The 16p11.2 CNV may therefore provide insight into the relationship between ASD and SCZ, distinct disorders that co-occur at an elevated rate, and are difficult to distinguish from each other and from common co-occurring diagnoses such as obsessive compulsive disorder (OCD), itself a potential risk factor for SCZ. As psychotic symptoms are core to SCZ but distinct from ASD, we sought to examine their predictors in a population (n = 546) of 16p11.2 CNV carriers and their noncarrier siblings recruited by the Simons Variation in Individuals Project. We hypothesized that psychotic symptoms would be most common in duplication carriers followed by deletion carriers and noncarriers, that an ASD diagnosis would predict psychotic symptoms among CNV carriers, and that OCD symptoms would predict psychotic symptoms among all participants. Using data collected across multiple measures, we identified 19 participants with psychotic symptoms. Logistic regression models adjusting for biological sex, age, and IQ found that 16p11.2 duplication and ASD diagnosis predicted psychotic symptom presence. Our findings suggest that the association between 16p11.2 duplication and psychotic symptoms is independent of ASD diagnosis and that ASD diagnosis and psychotic symptoms may be associated in 16p11.2 CNV carriers. Autism Res 2020, 13: 187-198. (c) 2019 International Society for Autism Research, Wiley Periodicals, Inc. LAY SUMMARY: Either deletion or duplication at chromosome 16p11.2 raises the risk of autism spectrum disorder, and duplication, but not deletion, has been reported in schizophrenia (SCZ). In a sample of 16p11.2 deletion and duplication carriers, we found that having the duplication or having an autism diagnosis may increase the risk of psychosis, a key feature of SCZ.
