First report of a large duplication of the KCNQ1 gene in a patient with long QT syndrome.

Understanding the limitations of routine genetic testing protocols is of critical importance for the clinician. Standard DNA sequencing protocols are a reliable method for the detection of single point mutations or small insertions and deletions. However, these protocols cannot detect the presence of large genomic rearrangements that might affect culprit genes.
