Understanding Your Results

Genetic test results for MYO7A gene mutations indicate the presence or absence of pathogenic variants associated with autosomal recessive deafness type 2. Interpretation should be done by a qualified geneticist in conjunction with clinical assessment.
Positive Result: Mutation(s) detected, confirming diagnosis of MYO7A gene deafness
Negative Result: No pathogenic mutation detected, but clinical correlation needed; other genetic causes may be considered
Variant of Uncertain Significance: Mutation identified with unclear clinical impact; further testing or family studies recommended
⚠️ When to Consult a Doctor:

If the test result is positive, variant of uncertain significance, or if there is persistent hearing loss or a family history of deafness, consult a geneticist or ENT specialist for further evaluation and management.

Limitations

  • ⚠May not detect all types of mutations or deep intronic variants
  • ⚠Results should be correlated with clinical findings and family history

Risks & Considerations

  • ●Minimal risk from blood draw, such as bruising or discomfort at the site
  • ●No significant risks associated with the genetic test itself

Interfering Factors

  • ●Poor DNA quality
  • ●Sample contamination
  • ●Hemolyzed blood sample

Frequently Asked Questions

What is MYO7A gene deafness?
MYO7A gene deafness is an autosomal recessive genetic condition caused by mutations in the MYO7A gene, leading to hearing loss due to impaired inner ear hair cell function.
How is the MYO7A NGS genetic test performed?
The test uses Next Generation Sequencing (NGS) to analyze the DNA sequence of the MYO7A gene from a blood or DNA sample, identifying mutations with high accuracy.
What is the cost of the test?
The cost is INR 20,000 in India, which includes sample collection, testing, and report generation.
Is home sample collection available?
Yes, DNA Labs India offers free home sample collection for this test across many cities in India.
How long does it take to get results?
Results are typically available within 3 to 4 weeks after sample collection.
What are the symptoms of MYO7A gene deafness?
Symptoms include difficulty hearing or complete deafness, balance problems, tinnitus, and speech delays in children.
Who should get this test?
Individuals with congenital hearing loss, a family history of autosomal recessive deafness, or symptoms suggestive of genetic hearing impairment.
Is the test accurate?
Yes, the NGS test has high sensitivity, detecting mutations with up to 99% accuracy, but results should be correlated clinically.
What do the results mean?
A positive result confirms a MYO7A gene mutation causing deafness; negative means no mutation found; uncertain variants require further evaluation.
Can this test be used for carrier testing?
Yes, it can identify carriers of MYO7A mutations in families with a history of the condition.
Are there any risks involved?
Risks are minimal, mainly related to blood draw, such as bruising. The genetic test itself poses no physical risk.
How do I prepare for the test?
No special preparation is needed, but genetic counseling is advised to understand the test implications and provide clinical history.
