Understanding Your Results

Results are reported as pathogenic variant detected or not detected. Genetic counseling is recommended for result interpretation.
📊

Pathogenic variant detected

Confirms a genetic cause of deafness in the MYH14 gene. Family members may be at risk.

📊

No pathogenic variant detected

MYH14 mutations not found. Consider other genetic tests or environmental factors.

⚠️ When to Consult a Doctor:

Consult a geneticist or ENT specialist if you have a family history of deafness or unexplained hearing loss, especially before family planning.

Limitations

  • ⚠May not detect all types of variants (e.g., large deletions)
  • ⚠Requires interpretation by a genetic specialist
  • ⚠Does not provide information on other deafness genes

Risks & Considerations

  • ●Minimal pain or bruising from blood draw
  • ●Psychological distress from genetic diagnosis
  • ●Risk of incidental findings

Interfering Factors

  • ●Degraded DNA samples
  • ●Contamination during sample processing
  • ●Technical errors in sequencing

Frequently Asked Questions

What is MYH14 Gene Deafness?
MYH14 Gene Deafness is a genetic condition caused by mutations in the MYH14 gene, leading to autosomal dominant hearing loss type 4 (DFNA4).
How is MYH14 Gene Deafness inherited?
It is inherited in an autosomal dominant pattern, meaning one copy of the mutated gene from an affected parent can cause the condition.
What are the symptoms of MYH14 Gene Deafness?
Symptoms include sensorineural hearing loss, tinnitus, difficulty understanding speech, and sensitivity to loud noises, varying in severity.
How is MYH14 Gene Deafness diagnosed?
Diagnosis is made through Next-Generation Sequencing (NGS) genetic testing to detect mutations in the MYH14 gene.
What is the cost of the MYH14 Gene Deafness NGS test in India?
The cost at DNA Labs India is INR 20,000, with free home sample collection available across India.
Is home sample collection available?
Yes, DNA Labs India offers free home sample collection for online bookings in numerous cities across India.
How long does it take to get the test results?
Results are typically available within 3 to 4 weeks after sample receipt.
What does a positive test result mean?
A positive result confirms a pathogenic mutation in the MYH14 gene, indicating genetic deafness. Genetic counseling is advised.
What if the test result is negative?
A negative result means no pathogenic MYH14 mutations were detected. Other causes of deafness should be investigated.
Can family members be tested?
Yes, if a pathogenic variant is identified, family members can undergo targeted testing to assess their risk.
Is genetic counseling recommended?
Yes, genetic counseling is recommended before and after testing to understand implications and results.
What files are provided with the test report?
DNA Labs India provides raw data, FASTQ, and VCF files along with the clinical test report for transparency.
