Understanding Your Results

Results indicate the presence or absence of mutations in the MYH9 gene. Positive findings confirm DFNA17, while negative results do not rule out other genetic causes.
📊

Pathogenic variant detected

Confirms diagnosis of DFNA17; genetic counseling recommended.

📊

No pathogenic variant detected

DFNA17 unlikely; consider other genetic or non-genetic causes.

📊

Variant of uncertain significance

Requires further evaluation and family studies.

⚠️ When to Consult a Doctor:

Consult a healthcare professional if you experience progressive hearing loss, have a family history of deafness, or need guidance on test results and management.

Limitations

  • ⚠Does not detect all genetic causes of hearing loss
  • ⚠May identify variants of uncertain significance
  • ⚠Requires genetic counseling for interpretation

Risks & Considerations

  • ●Minimal risks from blood draw: bruising, infection
  • ●Potential psychological impact of genetic results

Interfering Factors

  • ●Contaminated or degraded DNA sample
  • ●Recent blood transfusion
  • ●Improper sample storage or handling

Frequently Asked Questions

What is MYH9 Gene Deafness?
It is a genetic condition called autosomal dominant type 17 (DFNA17) causing progressive hearing loss due to MYH9 gene mutations.
Who should consider this test?
Individuals with progressive hearing loss, family history of deafness, or symptoms like tinnitus.
How is the test performed?
Using Next-Generation Sequencing (NGS) on a blood or DNA sample to analyze the MYH9 gene.
What does a positive result mean?
It confirms a diagnosis of DFNA17, guiding management and family risk assessment.
Is the test painful?
No, it involves a standard blood draw with minimal discomfort.
Can children take this test?
Yes, it is suitable for all ages with appropriate consent.
How accurate is NGS testing?
NGS is highly accurate for detecting genetic mutations, with over 99% coverage.
What if the result is negative?
DFNA17 is unlikely, but other causes should be evaluated by a healthcare professional.
Is home sample collection available?
Yes, free home collection is offered in many cities across India.
How long does it take to get results?
Reports are typically delivered in 3 to 4 weeks.
Is genetic counseling provided?
Yes, a genetic counseling session is recommended before and after testing.
Can this test detect other hearing loss genes?
No, it specifically targets the MYH9 gene; for broader analysis, consider a gene panel.
