Video Transcription

Video Summary

Joe, a 32-year-old with a family history of sudden death, is being evaluated for long QT syndrome. His QT interval is 440 ms, and his brother, with a worse QT reading and a defibrillator, survived sudden cardiac arrest. Their father's and paternal grandmother's sudden deaths suggest a genetic predisposition. The best course of action is to conduct genetic testing on Joe using a long QT syndrome gene panel. If a mutation is detected, cascade screening should be done for other family members to identify and manage potential risks, indicating the clinical benefit of genetic testing for the family.
