Sample Stability

Blood sample should be stored at room temperature or refrigerated; do not freeze.
Ship the sample to the laboratory on the same day of collection where possible.
Sample Rejection Criteria:
  • Clotted sample in a wrong anticoagulant tube.
  • Sample tube without patient identification.
  • Hemolyzed or severely lipemic sample.
  • Incomplete clinical history or consent form.

Understanding Your Results

The result should be interpreted in the context of clinical presentation, family history, and in consultation with a genetic specialist.
📊

Pathogenic variant detected

Confirms the diagnosis of hereditary neuralgic amyotrophy.

📊

No pathogenic variant detected

Does not exclude HNA; further evaluation may be needed if clinical suspicion remains.

📊

Variant of uncertain significance

Cannot be used for diagnosis; additional family studies may help clarify.

⚠️ When to Consult a Doctor:

Consult a neurologist or geneticist if you have recurrent shoulder and arm pain with weakness, or if a family member has been diagnosed with hereditary neuralgic amyotrophy.

Limitations

  • ⚠This test does not detect large chromosomal rearrangements, repeat expansions, or all deep intronic variants.
  • ⚠A negative result does not completely rule out HNA if clinical suspicion remains strong.
  • ⚠Variants of uncertain significance may require additional family segregation analysis.

Risks & Considerations

  • ●Minimal risk of bruising, bleeding, or infection at the puncture site.

Interfering Factors

  • ●Incorrect clinical or family history may affect result interpretation.
  • ●Poor sample quality or DNA degradation may compromise analysis.
  • ●Contamination during sample collection may affect NGS results.

Frequently Asked Questions

What is the 9-Sep Gene Amyotrophy Hereditary Neuralgic NGS Genetic Test?
It is a targeted NGS genetic test that analyzes the SEPT9 gene to detect mutations associated with hereditary neuralgic amyotrophy (HNA).
What is hereditary neuralgic amyotrophy?
HNA is a rare inherited disorder of the peripheral nervous system marked by recurrent episodes of severe shoulder and arm pain, muscle weakness, and atrophy.
What type of sample is required for this test?
A peripheral blood sample is required for the NGS genetic test.
Is fasting required before the test?
No, fasting is not required for this genetic test.
What is the cost of this test at DNA Labs India?
The test costs INR 20000 and includes free home sample collection, genetic counselling, and result interpretation.
How long does it take to receive the report?
The report is normally available within 3 to 4 weeks from sample receipt.
What is the method used for this test?
The test uses Next Generation Sequencing (NGS) technology to sequence the SEPT9 gene and identify disease-causing variants.
Who should consider taking this genetic test?
People with recurrent shoulder-arm pain and weakness, clinically suspected HNA, or a family history of the condition should consider this test.
Can this test confirm a diagnosis of hereditary neuralgic amyotrophy?
Yes, identifying a pathogenic variant in the SEPT9 gene in a person with compatible symptoms can confirm the diagnosis.
Is genetic counseling included in the test price?
Yes, genetic counseling is part of the package and is provided to help interpret results and recurrence risks.
Will health insurance cover this test?
Coverage is not guaranteed and depends on the policy. You can check with your insurer or our team for assistance.
Can the test help other family members?
Yes, a confirmed SEPT9 variant can help at-risk relatives understand their genetic risk and support reproductive and medical decisions.
