Rare singleton duplication within this region was found in a case from a study of 15,749 individuals from the International Standards for Cytogenomic Arrays (ISCA) consortium with unexplained developmental delay, intellectual disability, dysmorphic features, multiple congenital anomalies, autism spectrum disorders, or clinical features suggestive of a chromosomal syndrome (Kaminsky et al., 2011).
Consecutive cases examined in the Medical Genetics Unit at the "Citta della Salte e della Scienza" University Hospital (Turin, Italy) from 2008 to 2014 (cases with CNVs are present in DECIPHER database)
Cases diagnosed with idiopathic developmental delay and/or intellectual disability (DD/ID)
Galician (NW Spain) patients recruited from the Complexo Hospitalario Universitario de Santiago de Compostela and referred to the Fundacion Publica Galega de Medicina Xenomica for genetic study
All participants had a clinical diagnosis of idiopathic intellectual disability (ID) or global developmental delay (DD) with or without another medical condition [e.g. autism spectrum disorder (ASD), attention deficit hyperactivity disorder (ADHD), epilepsy, dysmorphic features, and/or congenital anomalies]
Individuals with severe congenital brain malformations [agenesis of the corpus callosum (ACC), cerebellar hypoplasia (CBLH), and/or polymicrogyria (PMG)] and additional neurodevelopmental phenotypes
Diagnosis of agenesis of the corpus callosum (ACC), cerebellar hypoplasia (CBLH), and/or polymicrogyria (PMG); additional diagnoses of autism spectrum disorder (ASD), developmental delay (DD), intellectual disability (ID) and/or seizures in some patients
