Understanding Your Results

The clinical report indicates whether a pathogenic or likely pathogenic variant was identified in the SLC1A3 gene. Please discuss the result with your referring physician or genetic counselor.
Positive (pathogenic variant detected): Confirms diagnosis of EA6; supports genetic counseling and management.
Negative (no pathogenic variant detected): Does not exclude EA6; other genetic or acquired causes should be considered.
Variant of Uncertain Significance (VUS): Additional family testing or functional studies may be required.
⚠️ When to Consult a Doctor:

If you experience recurrent episodes of ataxia, dizziness, or slurred speech, consult a neurologist for a detailed evaluation.

Limitations

  • ⚠NGS may not detect large deletions, duplications, or trinucleotide repeat expansions.
  • ⚠Deep intronic variants or variants in non-coding regions may not be fully assessed.
  • ⚠Results should be interpreted in the context of clinical symptoms and family history.

Risks & Considerations

  • ●Minor pain or bruising at the needle site
  • ●Rare risk of infection or excessive bleeding
