Errors in Table 2

In the Original Investigation titled “Accuracy of Next-Generation Sequencing for Molecular Diagnosis in Patients With Infantile Nystagmus Syndrome,”¹ published in the December 2017 issue of JAMA Ophthalmology, there were errors in Table 2. The homozygous c.709C>T mutation in NMNAT1 gene for patient 8 was incorrect; this has been corrected to compound; heterozygous c.709C>T (paternal inheritance):exon 4,5 deletion (maternal inheritance) in NMNAT1 gene, and a new reference and citation have been added. Also, footnote c for Table 2 was incorrect and has been deleted. A Letter of Explanation² has been published that details the source of these errors. This article was corrected online.
