Overview
The purpose of the Dystonia Gene Panel is to detect pathogenic variants in genes associated with hereditary dystonia. This aids in confirming a clinical diagnosis, differentiating between genetic and non-genetic causes, assessing risk for family members, and guiding therapeutic decisions. It is particularly useful for individuals with early-onset dystonia, a family history of the disorder, or atypical presentations.

Sample Collection
No special preparation is required. A doctor's prescription is needed for the test. Inform your doctor about any medications you are taking.
Method: Venipuncture / Amniocentesis / CVS
Laboratory Analysis
A blood sample will be drawn from a vein in your arm. For prenatal testing, amniocentesis or CVS will be performed by a specialist.
Report Delivery
You can resume normal activities immediately. For prenatal procedures, follow your doctor's advice regarding rest and monitoring.
Timeline: Reports are typically delivered within 4-6 weeks after the sample is received by the laboratory.

How to Prepare
- For blood: Use EDTA vacutainer, mix gently to prevent clotting.
- For amniotic fluid: Collect in sterile container, do not contaminate.
- For CVS: Collect in sterile container with normal saline.
- Transport at ambient temperature or cool pack as per instructions.

Understanding Your Results
Positive (Pathogenic variant detected)
Confirms genetic diagnosis; enables targeted management and family screening.
Negative (No pathogenic variant detected)
Does not exclude genetic cause; consider broader testing or other etiologies.
Variant of Uncertain Significance (VUS)
Insufficient evidence to classify; may require segregation analysis or functional studies.
If you or a family member have symptoms of dystonia, or if you have a known family history of genetic dystonia, consult a neurologist or genetic counselor to discuss the appropriateness of this test.
Limitations
- ⚠This panel does not detect all possible genetic causes of dystonia; other genes may be involved.
- ⚠Negative results do not exclude a genetic cause.
- ⚠Variant interpretation may require additional family studies.
- ⚠Not intended for diagnostic use in individuals without clinical features of dystonia.
Risks & Considerations
- ●Blood draw: minor bruising or discomfort
- ●Amniocentesis: small risk of miscarriage or infection
- ●CVS: small risk of miscarriage or limb defects
- ●Psychological impact of genetic results
Interfering Factors
- ●Contamination of sample with maternal cells in prenatal specimens
- ●Insufficient DNA quantity or quality
- ●Presence of large deletions/duplications not detected by NGS
- ●Variants of uncertain significance (VUS) requiring further analysis
Compare With Similar Tests
| Test | Dystonia Gene Panel | Whole Exome Sequencing (WES) | Single Gene Testing |
|---|---|---|---|
| Comparison | Dystonia Gene Panel | WES analyzes all coding regions of the genome, offering broader coverage but at a higher cost and longer turnaround time. The targeted panel is more cost-effective and faster for known dystonia genes. | Single gene testing is useful when a specific gene is strongly suspected based on phenotype, but the panel is more efficient when multiple genes are possible. |
