Test Overview & Methodology
The GJB2 gene (DFNA3A) NGS test identifies single nucleotide variants, small insertions/deletions, and copy number changes responsible for autosomal dominant deafness DFNA3A. This precise genetic analysis enables targeted genetic counseling, early auditory rehabilitation, and informed family planning decisions.
| Criteria | Our NGS Test | Closest Alternative (Sanger Sequencing) |
|---|---|---|
| Precision | >99.9% analytical sensitivity, full gene coverage | Targeted only, limited to hot‑spots |
| Method | Next Generation Sequencing (Illumina) | Sanger sequencing |
| Turnaround Time | 3–4 Weeks | 4–6 Weeks |
| Sample | Blood (EDTA), Extracted DNA, or FTA Card | Blood or DNA only |
| UAE Home Collection | Included (VIP Phlebotomy) | Often unavailable |
| Price | 2800 AED | Variable (often higher) |
Physician Insight & Safety Protocols
“The diagnosis of hereditary hearing loss can be overwhelming. This NGS test offers families a clear genetic explanation and helps tailor long-term auditory care. Remember, this genetic result must be correlated with a full clinical evaluation and audiometric data.” – Lina Osama Zaki Quteineh, Consultant Medical Genetics, DHA Registration ID: 9294403
Essential Advisory Notice
⚠️ Critical Clinical Guidance
Do not discontinue or alter any prescribed medication without consulting your physician. This genetic test is an adjunct to professional otolaryngologic follow-up and does not replace comprehensive medical care.
Patient Safety Exclusion & Red Flags
Exclusion Criteria: Active ear infection or recent otologic surgery (less than 4 weeks) may require physician clearance before venipuncture. Genetic testing in minors without appropriate counseling is restricted under UAE Federal Decree-Law No. 4 of 2016 on Medical Liability.
Emergency Red Flags: Sudden severe hearing loss with vertigo, acute tinnitus, facial weakness, or new neurological symptoms require immediate hospital evaluation.
Patient FAQ & Clinical Guidance
1. What exactly does this GJB2 gene test detect?
It detects single nucleotide variants, small insertions/deletions, and copy number changes in the entire GJB2 gene that cause autosomal dominant deafness DFNA3A. The test provides full gene coverage using next-generation sequencing technology.
2. How long does it take to receive my results?
Results are typically reported within 3 to 4 weeks from the moment the sample arrives at our ISO 9001:2015 accredited laboratory. You will be notified via phone and email once your report is ready for review.
3. Is home blood collection available across the UAE?
Yes, our DHA-licensed phlebotomists perform VIP Mobile Phlebotomy home visits from 8 AM to 11 PM in Dubai, Abu Dhabi, Sharjah, and all emirates. All samples are transported using temperature-controlled cold-chain logistics for optimal specimen integrity.
4. Will my health insurance cover this genetic test?
Coverage varies by insurance provider and policy. Contact our billing team via WhatsApp at +971 54 548 8731 for direct verification and pre-authorization assistance.
5. What preparation is required before the blood draw?
No special preparation is needed for this genetic test. You may eat and drink normally before your appointment. Please inform the phlebotomist of any blood clotting disorders or anticoagulant medications.
