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.

Evaluating heterogeneity in ASD symptomatology, cognitive ability, and adaptive functioning among 16p11.2 CNV carriers / Caitlin M. HUDAC in Autism Research, 13-8 (August 2020)

HUDAC, Auteur ; Joanna BOVE, Auteur ; Shelley BARBER, Auteur ; Michael DUYZEND, Auteur ; Ari WALLACE, Auteur ; Christa Lese MARTIN, Auteur ; David H.

EICHLER, Auteur ; Raphael BERNIER, Auteur Article en page(s) : p.1300-1310 Langues : Anglais (eng) Mots-clés : 16p11.2 deletion  16p11.2 duplication  adaptive functioning  autism spectrum disorder  cognitive functioning  individual variability/heterogeneity Index. décimale : PER Périodiques Résumé : Individuals with 16p11.2 copy number variant (CNV) show considerable phenotypic heterogeneity. 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.

Impact of a Genetic Diagnosis for a Child?s Autism on Parental Perceptions / Anna KARLSEN ; Benjamin HUBER ; Alina LEVINE ; Amanie SALEM ; L.

However, the impact on parents of receiving a monogenetic/ copy number variant diagnosis for autism in their child is not well understood. To explore this, we surveyed and interviewed parents of children in the SPARK study, a study of autism that includes genetic testing. Surveys were administered one month before and one and 12 months after parents received their child?s genetic result. Interviews were conducted approximately one month after results disclosure. A genetic diagnosis (GD) for their child appeared to reduce parents' sense of self-blame and feelings of guilt, and this impact was relatively stable. The data also indicate a modest impact on parents' actions related to the condition, perceptions of themselves, and some aspects of life planning for their child, as measured by quantitative instruments at one month and 12 months after receipt of results. Other measures of parental identity and expectations for their child, in contrast, showed little change following receipt of genetic findings. Overall, parents who were told that no GD was identified showed minimal changes in their responses over time. These results suggest a discernable but relatively limited impact of genetic test results on parents of children with autism. These results should be reassuring to clinicians caring for children with autism and are consistent with studies in other areas of medicine that have suggested that genetic results tend to have fewer effects-negative or positive-than were anticipated.

Impact of Receiving Genetic Diagnoses on Parents' Perceptions of Their Children with Autism and Intellectual Disability / Robert Klitzman ; Ekaterina Bezborodko ; Wendy K. CHUNG ; Paul S. APPELBAUM in Journal of Autism and Developmental Disorders, 55-1 (January 2025)

Diagnosis of a de novo genetic variant can alter parental perceptions of offspring with autism and other NDDs. Parents often blamed their child less, saw their child as less in control of symptoms, and developed more patience, framing expectations accordingly. Parents had mixed feelings about receiving genetic diagnoses, with sadness sometimes accompanying reframed expectations. Genetic diagnoses could change views of the child among extended family members, teachers, social service agencies, insurers, and broader communities and society. Genetic testing might also reduce delays in diagnoses of autism among African American, Latino and other children. These data, the first to examine several critical aspects of how parents and others view children with autism and other NDDs after receiving genetic diagnoses, highlight vital needs for education of multiple stakeholders (including geneticists, other physicians, genetic counselors, parents, individuals with autism, social service agencies, insurers, policymakers, and the broader public), research (to include perspectives of extended family members, insurers, social service agencies and teachers) and practice (to increase recognition and awareness of the potential benefits and effects of genetic testing for such children).
