Childhood-onset schizophrenia is rare, comprising 1% of known schizophrenia cases. Here, we report a patient with childhood-onset schizophrenia who has three large chromosomal abnormalities: an inherited 2.2 Mb deletion of chromosome 3p12.2-p12.1, a de novo 16.7 Mb duplication of 16q22.3-24.3, and a de novo 43 Mb deletion of Xq23-q28.
