Understanding Your Results

Interpretation of FZD4 gene test results for exudative vitreoretinopathy involves assessing detected mutations and their clinical significance.
Positive result: Pathogenic mutation detected, indicating increased risk for EVR. Genetic counseling recommended.
Negative result: No pathogenic mutations detected, but clinical evaluation should continue if symptoms persist.
Variant of uncertain significance: Requires further evaluation and family studies for clarification.
⚠️ When to Consult a Doctor:

If you experience symptoms like decreased vision or have a family history of EVR, consult a genetic counselor or ophthalmologist for test guidance and management.

Limitations

  • ⚠May not detect all FZD4 gene mutations
  • ⚠Results require clinical correlation
  • ⚠Variant of uncertain significance may occur

Risks & Considerations
