📊

Positive for pathogenic mutation

Confirms diagnosis of LQTS Type 5. Consult a genetic counselor and cardiologist for management.

📊

Negative for mutations

No pathogenic variants detected in KCNE1 gene. Clinical correlation and further testing may be needed.

📊

Variant of uncertain significance (VUS)

Mutation detected but clinical significance unknown. Follow-up testing and family studies recommended.

⚠️ When to Consult a Doctor:

If you experience symptoms like fainting, palpitations, or have a family history of LQTS, consult a cardiologist or genetic specialist immediately.
