Abstract

Abstract : Copy number variability at 16p13.11 has been associated with intellectual disability, autism, schizophrenia, epilepsy, and attention‐deficit hyperactivity disorder. Adolescent/adult‐ onset psychosis has been reported in a subset of these cases. Here, we report on two children with CNVs in 16p13.11 that developed psychosis before the age of 7. The genotype and neuropsychiatric abnormalities of these patients highlight several overlapping genes that have possible mechanistic relevance to pathways previously implicated in Autism Spectrum Disorders, including the mTOR signaling and the ubiquitin‐proteasome cascades. A careful screening of the 16p13.11 region is warranted in patients with childhood onset psychosis. © 2016 Wiley Periodicals, Inc.
