Genomic Disorders in Psychiatry —What Does the Clinician Need to Know?

AbstractPurpose of ReviewThe purpose of this review is to summarize the role of genomic disorders in various psychiatric conditions and to highlight important recent advances in the field that are of potential clinical relevance.Recent FindingsGenomic disorders are caused by large rare recurrent deletions and duplications at certain chromosomal “hotspots” (e.g., 22q11.2, 16p11.2, 15q11-q13, 1q21.1, 15q13.3) across the genome. Most overlap multiple genes, affect development, and are associated with variable cognitive and other neuropsychiatric expression. Although individually rare, genomic disorders collectively account for a significa nt minority of intellectual disability, autism spectrum disorder, and schizophrenia.SummaryGenome-wide chromosomal microarray analysis is capable of detecting all genomic disorders in a single test, offering the first opportunity for routine clinical genetic testing in psychiatric practice.
