Understanding Your Results

Results indicate the presence or absence of pathogenic variants in the KCTD17 gene. A positive result confirms DYT26 diagnosis, while a negative result may require further testing or clinical evaluation.
📊

Positive for pathogenic variants

Confirms diagnosis of DYT26; genetic counseling and management advised.

📊

Negative for pathogenic variants

DYT26 unlikely; consider other differential diagnoses or additional tests.

📊

Variant of uncertain significance

Further clinical correlation and family studies recommended.

⚠️ When to Consult a Doctor:

Consult a neurologist or genetic specialist if symptoms of dystonia are present, or if there is a family history of movement disorders, for appropriate testing and management.

Limitations

  • ⚠May not detect all genetic variants or mutations in non-coding regions
  • ⚠Results require interpretation by a genetic specialist
  • ⚠Does not rule out other causes of dystonia

Risks & Considerations

  • ●Minor bruising or discomfort at blood draw site
  • ●Psychological impact of genetic results
  • ●Potential for uncertain or unexpected findings

Interfering Factors

  • ●Sample contamination
