Sample Collection
No fasting is required. Please bring the clinical history and any prior medical records regarding dystonia. A genetic counselling session must be completed and informed consent signed before sample collection.
Method: Peripheral blood draw or FTA card blood spot
Laboratory Analysis
A trained phlebotomist will draw blood from a vein in your arm. If using an FTA card, a few drops of blood are applied. The procedure takes less than 10 minutes.
Report Delivery
You may leave immediately and resume normal activities. The sample will be sent to the laboratory for processing.
Timeline: Reports are usually available within 3 to 4 weeks of the sample reaching the laboratory.

About This Test
Who Should Get This Test
To detect disease-causing genetic variants that may explain inherited forms of dystonia. This information can support clinical diagnosis, risk stratification, and informed decision-making for affected families.
How to Prepare
- No fasting required.
- Complete pre-test genetic counselling and sign the consent form.
- Inform the laboratory about blood transfusion or stem cell transplant history.
- For FTA card, apply one drop of blood as per the provided card instructions.
Doctor's Notes
Reviewed by Dr SULOCHANA HEMCHANDRA HOLLA — MBBS, MD (Medical Genetics) · Reg. No. 8532
"A positive genetic test in a patient with dystonia can have implications not only for neurological management but also for family planning and prenatal risk. Therefore, testing should always be accompanied by appropriate genetic counselling."

Test Parameters & Specifications
Sample Stability
- Sample tube broken or leaking.
- Haemolysed or clotted blood.
- FTA card not dried properly or contaminated.
- Missing patient identification, consent, or clinical history.
Understanding Your Results
Negative
No pathogenic or likely pathogenic variant was detected in the dystonia-related genes analyzed.
Positive
A pathogenic or likely pathogenic variant was identified, supporting a genetic/inherited dystonia diagnosis in the appropriate clinical context.
Variant of Uncertain Significance (VUS)
A genetic variant was found whose clinical effect is not yet established. Additional family testing may help clarify its significance.
If you or a family member experience involuntary muscle spasms, abnormal postures, or have a known family history of dystonia, consult a neurologist or clinical geneticist to assess whether genetic testing is appropriate.
Limitations
- ⚠This panel may not include all dystonia-related genes; a negative result does not exclude genetic dystonia.
- ⚠Large gene rearrangements, repeat expansion disorders, and mitochondrial variants may not be reliably detected depending on the bioinformatics pipeline.
- ⚠Variants of uncertain significance may be reported without providing a definitive diagnosis.
- ⚠Results should always be interpreted in the context of clinical findings and family history.
Risks & Considerations
- ●Minimal risk of brief pain, bruising, or rarely infection at the blood draw site.
- ●Possible psychological stress while waiting for results.
- ●Uninformative results, such as a variant of uncertain significance, may require further family studies.
Interfering Factors
- ●Clotted, haemolysed, or incorrectly stored blood samples can lead to poor DNA quality.
- ●Insufficient DNA quantity may affect NGS library preparation.
- ●Failure to disclose a prior bone marrow or stem cell transplant may result in donor-derived DNA results.

| Test | Dystonia Panel NGS Genetic Test | Single Gene Dystonia Test | Whole Exome Sequencing | Chromosomal Microarray |
|---|---|---|---|---|
| Comparison | Dystonia Panel NGS Genetic Test | A panel offers a broader analysis, while a single gene test is used when a specific dystonia gene is already strongly suspected based on clinical features. | Whole exome sequencing covers far more genes and may detect genes outside the dystonia panel, but it has a longer turnaround time and higher interpretation burden. | A panel detects small sequence variants in targeted genes, whereas a microarray primarily detects large copy number changes across chromosomes. |
