Understanding Your Results

Results indicate the presence or absence of pathogenic variants in the GATA6 gene. Positive results suggest a genetic cause for Tetralogy of Fallot, while negative results do not rule out other genetic or environmental factors.
Pathogenic variant detected: Confirms genetic etiology, recommend genetic counseling and family screening.
Variant of uncertain significance: Requires further evaluation and clinical correlation.
No pathogenic variant detected: Consider other genetic tests or environmental factors.
⚠️ When to Consult a Doctor:

Consult a doctor if symptoms of Tetralogy of Fallot persist, for genetic counseling after a positive result, or for family planning advice.

Limitations

  • ⚠Results require clinical correlation and genetic counseling

Risks & Considerations

  • ●Minor bruising or discomfort at the blood draw site
  • ●Rare risk of infection

Interfering Factors

  • ●Sample quality or contamination
