Li, Kuokuo; Fang, Zhenghuan; Zhao, Guihu; Li, Bin; Chen, Chao; Xia, Lu; Wang, Lin; Luo, Tengfei; Wang, Xiaomeng; Wang, Zheng; Zhang, Yi; Jiang, Yi; Pan, Qian; Hu, Zhengmao; Guo, Hui; Tang, Beisha; Liu, Chunyu; Sun, Zhongsheng; Xia, Kun; Li, Jinchen – Journal of Autism and Developmental Disorders, 2022
The clinical similarity among different neuropsychiatric disorders (NPDs) suggested a shared genetic basis. We catalogued 23,109 coding de novo mutations (DNMs) from 6511 patients with autism spectrum disorder (ASD), 4,293 undiagnosed developmental disorder (UDD), 933 epileptic encephalopathy (EE), 1022 intellectual disability (ID), 1094…

Demily, Caroline; Lesca, Gaétan; Poisson, Alice; Till, Marianne; Barcia, Giulia; Chatron, Nicolas; Sanlaville, Damien; Munnich, Arnold – Journal of Autism and Developmental Disorders, 2018
The "22q11.2 duplication" is a variably penetrant copy number variant (CNV) associated with a broad spectrum of clinical manifestations including autism spectrum disorders (ASD), and epilepsy. Here, we report on pathogenic "HUWE1" and "KIF1A" mutations in two severely affected ASD/ID participants carrying a 22q11.2…

Lumish, Heidi S.; Wynn, Julia; Devinsky, Orrin; Chung, Wendy K. – Journal of Autism and Developmental Disorders, 2015
Whole exome sequencing (WES) has been utilized with increasing frequency to identify mutations underlying rare diseases. 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…

Pescosolido, Matthew F.; Gamsiz, Ece D.; Nagpal, Shailender; Morrow, Eric M. – Journal of the American Academy of Child & Adolescent Psychiatry, 2013
Objective: The purpose of the present study was to discover the extent to which distinct "DSM" disorders share large, highly recurrent copy number variants (CNVs) as susceptibility factors. We also sought to identify gene mechanisms common to groups of diagnoses and/or specific to a given diagnosis based on associations with CNVs. Method:…

Beaudet, Arthur L. – Child Development, 2013
Chromosomal microarray analysis (CMA) has emerged as a powerful new tool to identify genomic abnormalities associated with a wide range of developmental disabilities including congenital malformations, cognitive impairment, and behavioral abnormalities. CMA includes array comparative genomic hybridization (CGH) and single nucleotide polymorphism…

Bahi-Buisson, Nadia; Nectoux, Juliette; Rosas-Vargas, Haydee; Milh, Mathieu; Boddaert, Nathalie; Girard, Benoit; Cances, Claude; Ville, Dorothee; Afenjar, Alexandra; Rio, Marlene; Heron, Delphine; Morel, Marie Ange N'Guyen; Arzimanoglou, Alexis; Philippe, Christophe; Jonveaux, Philippe; Chelly, Jamel; Bienvenu, Thierry – Brain, 2008
Mutations in the human X-linked cyclin-dependent kinase-like 5 ("CDKL5") gene have been shown to cause infantile spasms as well as Rett syndrome (RTT)-like phenotype. To date, less than 25 different mutations have been reported. So far, there are still little data on the key clinical diagnosis criteria and on the natural history of…

Bolton, Patrick F. – Mental Retardation and Developmental Disabilities Research Reviews, 2004
Tuberous sclerosis is a genetic condition that is strongly associated with the development of an autism spectrum disorder. However, there is marked variability in expression, and only a subset of children with tuberous sclerosis develop autism spectrum disorder. Clarification of the mechanisms that underlie the association and variability in…
