Brugada Syndrome Caused by a Large Deletion in SCN5A Only Detected by Multiplex Ligation-Dependent Probe Amplification

Abstract excerpt

A 14-year-old boy presented with atrial flutter. His ECG showed Brugada changes, first-degree AV block and major sinus pauses. Polymorphic VT was inducible at electrophysiology study. A pacemaker defibrillator was placed. Classic sequencing for SCN5A was normal. Multiplex ligation-dependent probe amplification, however, detected a major deletion in SCN5A. It is predicted that this deletion would result in...
