Long QT Syndrome Panel Test code: 02211 • 10–21 days turnaround time Up to 17 genes

Long QT Syndrome Panel

This test is intended for individuals with a clinical diagnosis or suspected diagnosis of Long QT Syndrome (LQTS). The panel evaluates genes that are definitively associated with LQTS, as well as genes linked to other inherited cardiac arrhythmia disorders that may present with clinical features similar to LQTS.

Genetic testing may provide valuable information for individuals experiencing symptoms or clinical findings associated with LQTS. Testing can help:

• Establish or confirm a diagnosis
• Identify an inherited genetic cause of the condition
• Clarify potential health and arrhythmia risks
• Support individualized medical management
• Guide appropriate monitoring and risk-reduction strategies
• Provide information for family genetic counseling and testing

Family Testing:
Asymptomatic family members of an individual with a known pathogenic variant associated with LQTS may also benefit from targeted genetic testing. Identifying individuals who carry a familial pathogenic variant may allow for appropriate medical evaluation and help them avoid certain activities, medications, or other potential triggers that could increase the risk of abnormal heart rhythms or symptoms.

Genetic results may also help identify other family members who could benefit from clinical evaluation and genetic counseling.
