Understanding Your Results

Results from the KCNC3 gene test indicate the presence or absence of mutations associated with SCA13.
Positive: Pathogenic mutation detected in the KCNC3 gene, confirming diagnosis of SCA13.
Negative: No pathogenic mutations detected, but clinical correlation is needed.
Variant of Uncertain Significance (VUS): A genetic variant was found, but its association with disease is unclear. Further testing or family studies may be required.
⚠️ When to Consult a Doctor:

Consult a neurologist or genetic counselor immediately if the test is positive for SCA13 to discuss management options, genetic counseling, and family planning.

Limitations

  • ⚠Test is limited to known mutations in the KCNC3 gene
  • ⚠May not detect all types of genetic variations
  • ⚠Does not rule out other genetic causes of ataxia

Risks & Considerations

  • ●Minimal risk from blood draw, such as bruising or infection at the puncture site

Interfering Factors

  • ●Contaminated DNA sample
  • ●Insufficient sample volume
  • ●Improper sample storage

Frequently Asked Questions

What is Spinocerebellar Ataxia Type 13 (SCA13)?
SCA13 is a rare genetic disorder caused by mutations in the KCNC3 gene, affecting movement and coordination.
What are the common symptoms of SCA13?
Symptoms include uncoordinated movements, balance problems, tremors, speech difficulties, and eye movement issues.
How is SCA13 diagnosed?
Diagnosis involves clinical evaluation, MRI scans, and genetic testing to detect KCNC3 gene mutations.
What genetic test does DNA Labs India offer for SCA13?
DNA Labs India offers an NGS-based genetic test that analyzes specific regions of the KCNC3 gene.
What is the cost of the KCNC3 genetic test?
The test costs INR 20,000 and includes free home sample collection across India.
Is home sample collection available for this test?
Yes, DNA Labs India provides free home sample collection for online bookings in many cities.
How long does it take to get the test results?
Results are typically available in 3 to 4 weeks from sample collection.
Can genetic testing for SCA13 help with family planning?
Yes, since SCA13 is autosomal dominant, there is a 50% chance of passing the mutation to children, aiding in family planning decisions.
What does a positive test result indicate?
A positive result means a pathogenic mutation in the KCNC3 gene was detected, confirming SCA13 diagnosis.
Are there any risks associated with this genetic test?
The test involves a blood draw, which has minimal risks like bruising. The genetic test itself has no direct risks.
How should I prepare for the KCNC3 genetic test?
No special preparation is needed. Bring a valid ID and inform the lab about any medications.
What if the test result is negative?
A negative result means no pathogenic mutations were found, but clinical symptoms may require further evaluation.
