In the Original Investigation titled “Identification of Neuropsychiatric Copy Number Variants in a Health Care System Population”1 published online July 22, 2020, there were errors in Figure 1 and Table 1. In panel B of Figure 1, there was a missing vertical line in the pedigree chart. In Table 1, the DiscovEHR, deCODE, and UK Biobank values were switched for deletion and CNV and the number of deCODE 16p13.11 deletion cases should be 38. This article was corrected online.
