Understanding Your Results

Test results indicate the presence or absence of mutations in the MYO6 gene associated with deafness.
Positive: Pathogenic variant detected, confirming genetic deafness risk.
Negative: No pathogenic variants found, but does not rule out other causes.
Variant of Uncertain Significance (VUS): Requires further investigation and genetic counseling.
⚠️ When to Consult a Doctor:

If you have a family history of hearing loss, experience progressive deafness, or receive a positive genetic test result.

Frequently Asked Questions

What is MYO6 Gene Deafness?
MYO6 Gene Deafness, or Autosomal Dominant Type 22 (DFNA22), is a hereditary condition caused by mutations in the MYO6 gene, leading to progressive hearing loss.
How is the test performed?
The test uses Next-Generation Sequencing (NGS) to analyze DNA from a blood sample for mutations in the MYO6 gene.
What are the symptoms of MYO6 Gene Deafness?
Symptoms include difficulty hearing high-pitched sounds, trouble following conversations in noise, tinnitus, and progressive hearing loss.
Who should consider this genetic test?
Individuals with a family history of hearing loss, unexplained deafness, or symptoms suggestive of hereditary hearing impairment.
What does a positive test result mean?
A positive result indicates a pathogenic variant in the MYO6 gene, confirming a genetic predisposition to deafness.
Is genetic counseling necessary before testing?
Yes, genetic counseling is recommended to understand the test's implications, benefits, and limitations.
How accurate is the NGS genetic test?
NGS technology provides high accuracy in detecting genetic variants, but all results should be interpreted in a clinical context.
What is the cost of the test in India?
The test costs INR 20,000, which includes sample collection and report generation.
Is home sample collection available?
Yes, DNA Labs India offers free home sample collection across many cities in India.
How long does it take to get the results?
Results are typically available within 3 to 4 weeks after sample collection.
Are there any risks associated with the test?
The test involves a standard blood draw with minimal risks such as pain or bruising. Psychological impact of results should be considered.
Can the test be covered by insurance?
Coverage depends on your insurance provider and policy. It is advisable to check with your insurer beforehand.
