Understanding Your Results

Results indicate the presence or absence of SCN5A gene mutations associated with SIDS susceptibility. Consult a genetic counselor for detailed interpretation.
📊

Negative

No pathogenic variants detected in SCN5A gene. Reduced genetic risk, but other factors may contribute.

📊

Positive

Pathogenic variant detected. Increased genetic susceptibility to SIDS. Recommend genetic counseling and cardiac monitoring.

📊

VUS

Variant of uncertain significance. Further testing and family studies may be needed.

⚠️ When to Consult a Doctor:

Consult a healthcare provider or genetic counselor if results are positive or if there is a family history of SIDS or cardiac conditions.

Limitations

  • ⚠Test may not detect all genetic variants
  • ⚠Results require interpretation by a genetic counselor
  • ⚠Does not diagnose SIDS definitively, only assesses genetic susceptibility

Risks & Considerations

  • ●Minimal risk from blood draw, such as bruising or infection
  • ●Psychological impact of genetic results

Interfering Factors

  • ●Poor sample quality
  • ●Contaminated DNA
  • ●Technical errors in sequencing

Frequently Asked Questions

What is the SCN5A gene?
The SCN5A gene encodes a sodium channel protein essential for regulating heart electrical activity. Mutations can lead to arrhythmias.
What is Sudden Infant Death Syndrome (SIDS)?
SIDS is the unexplained death of an otherwise healthy infant, usually during sleep, often without warning signs.
How does SCN5A mutation relate to SIDS?
Mutations in SCN5A can disrupt heart rhythm, potentially causing fatal arrhythmias that may contribute to SIDS.
Who should consider this genetic test?
Families with a history of SIDS, unexplained infant deaths, or known SCN5A mutations should consider testing.
How is the test performed?
The test uses next-generation sequencing (NGS) to analyze the SCN5A gene from a blood or DNA sample.
What sample is required for the test?
Blood, extracted DNA, or one drop of blood on an FTA card can be used.
How long does it take to get results?
Results are typically available in 3 to 4 weeks after sample collection.
What does a positive result mean?
A positive result indicates a pathogenic SCN5A variant, suggesting increased genetic susceptibility to SIDS. Genetic counseling is recommended.
What does a negative result mean?
A negative result means no pathogenic variants were detected, reducing genetic risk, but other factors may still contribute.
Is genetic counseling provided?
Yes, DNA Labs India offers genetic counseling sessions to discuss test results and implications.
What is the cost of the test?
The test costs INR 20000, with free home sample collection available across India.
Is the test covered by insurance?
Coverage varies by insurance plan. Check with your provider for details on genetic testing coverage.
