Understanding Your Results

Results indicate the presence or absence of pathogenic mutations in the ST3GAL3 gene. A positive result confirms EIEE Type 15, while a negative result may require further testing or clinical correlation.
Positive: Pathogenic variant detected – confirms diagnosis of EIEE Type 15.
Negative: No pathogenic variants – clinical correlation recommended; consider other genetic or non-genetic causes.
Variant of uncertain significance (VUS) – further evaluation and family studies may be needed.
⚠️ When to Consult a Doctor:

Consult a geneticist or neurologist if seizures, developmental delays, or other symptoms are observed in infants, or for genetic counseling after test results to understand inheritance and management.

Risks & Considerations

  • ●Minor bruising or soreness at the blood draw site
  • ●Very rare risk of infection

Frequently Asked Questions

What is ST3GAL3 Gene EIEE Type 15?
EIEE Type 15 is a rare genetic disorder caused by mutations in the ST3GAL3 gene, leading to early-onset seizures and neurological issues.

The test costs INR 20000 at DNA Labs India, with free home sample collection available.
Is home sample collection available?
Yes, free home collection is offered across India for this test.
How long does it take to get results?
Results are typically available in 3 to 4 weeks after sample collection.
What do the results mean?
A positive result confirms EIEE Type 15, a negative result may indicate no pathogenic variants, and a VUS requires further evaluation.
Is genetic counseling required?
Yes, genetic counseling is recommended before testing to draw a pedigree chart and understand implications.
Can this test be done for adults?
The test is primarily for infants with symptoms, but it can be performed at any age if indicated by a specialist.
What are the risks of the test?
Risks are minimal, such as minor bruising at the blood draw site.
How accurate is the test?
