Understanding Your Results

Results indicate the presence or absence of pathogenic variants in the KCNE2 gene. A positive result confirms KCNE2-related Long QT Syndrome Type 6.
📊

Positive

Pathogenic variant detected, indicating increased risk for LQTS Type 6. Clinical correlation and genetic counseling recommended.

📊

Negative

No pathogenic variant detected. However, clinical symptoms may require further evaluation.

📊

Variant of Uncertain Significance

Genetic variant found but significance unknown. Further testing and family studies may be needed.

⚠️ When to Consult a Doctor:

If you experience symptoms like fainting, palpitations, or have a family history of sudden cardiac death.

Limitations
