Understanding Your Results

Interpretation of the SNTA1 Gene NGS Genetic Test results involves identifying pathogenic mutations associated with LQTS Type 12. A positive result indicates a genetic cause for the condition, while a negative result may not entirely rule out LQTS if other genes are involved.
Positive Result: Pathogenic mutation detected in SNTA1 gene, confirming LQTS Type 12. Genetic counseling and cardiac evaluation are recommended.
Negative Result: No pathogenic variants found in SNTA1 gene. Consider testing for other LQTS genes if clinical suspicion remains.
Variant of Uncertain Significance (VUS): A genetic change with unknown clinical significance. Further testing and family studies may be needed.
⚠️ When to Consult a Doctor:

Consult a healthcare provider if you experience symptoms like fainting, irregular heartbeat, or chest pain, especially with a family history of LQTS. After testing, discuss results with a geneticist or cardiologist for management.

Limitations

  • ⚠This test only analyzes the SNTA1 gene; other LQTS-related genes are not covered.
  • ⚠Results may require confirmation with additional clinical evaluation.
  • ⚠Genetic variants of uncertain significance may be identified.

Risks & Considerations

  • ●Minor pain or bruising at the blood draw site
  • ●Rare risk of infection or fainting during collection
