In the perinatal setting, chromosome imbalances cause a wide range of clinically significant disorders and increase risk for other particular phenotypes. As technologies have improved to detect increasingly smaller deletions and duplications, collectively referred to as copy number variants (CNVs), we are learning the significant role that these types of genomic variants play in human disease and their relatively high frequency in ~1% of all pregnancies. In this overview, we will highlight key aspects of CNV detection and interpretation used during the course of clinical care in the prenatal and neonatal periods. Since CNVs are one of the most frequent causes of a broad spectrum of human disorders, early diagnosis and accurate interpretation is important to implement timely interventions and targeted clinical management.
