Understanding Your Results

Results indicate the presence or absence of pathogenic mutations in the NF2 gene. Positive results confirm NF2 diagnosis, while negative results may require further clinical evaluation.
📊

Positive for NF2 mutation

Confirms diagnosis of Neurofibromatosis type 2; genetic counseling and management recommended.

📊

Negative for NF2 mutation

No pathogenic variant detected; clinical correlation and additional testing may be needed if symptoms persist.

📊

Variant of uncertain significance

Further analysis and family studies recommended for clarification.

⚠️ When to Consult a Doctor:

Consult a doctor if you experience symptoms like hearing loss, balance issues, or vision problems, especially with a family history of NF2. After testing, discuss results with a genetic counselor or neurologist for appropriate management.

Limitations

  • ⚠May not detect all types of mutations, such as large deletions
  • ⚠Requires genetic counseling for interpretation
  • ⚠Results should be correlated with clinical findings

Risks & Considerations
