Test Overview & Methodology
The GJB3 gene test identifies mutations in the connexin 31 protein gene associated with autosomal recessive nonsyndromic sensorineural hearing loss. It uses Next Generation Sequencing (NGS) to deliver definitive genetic evidence for family planning and clinical management.

Physician Insight & Safety Protocols
Lina Osama Zaki Quteineh, Consultant Medical Genetics (DHA 9294403), advises: “An abnormal GJB3 result confirms a genetic aetiology, but interpretation must always integrate audiometric data and a three-generation pedigree. Even a negative report requires correlation with clinical findings, as other genes may be responsible. Never discontinue prescribed audiological or medical therapy without consulting your physician.”
Medication Advisory
Medication Advisory:
Do not discontinue prescribed medication (e.g., corticosteroids, antivertigo drugs) without consulting your doctor. This test provides genetic information only; it does not replace acute medical management.
Exclusion Criteria & ER Red Flags
- Active infection at venipuncture site or one-drop blood collection area
- Severe coagulopathy or bleeding disorder
- Inability to provide informed consent or lack of legal guardian (for minors, strict compliance with Federal Law No. 2 of 2019)
- Seek emergency care if: sudden total hearing loss, acute dizziness with nystagmus, severe otalgia, or ear discharge with fever.
Patient FAQ & Clinical Guidance
1. What does the GJB3 gene test detect, and why is it important for autosomal recessive deafness?
The GJB3 gene test identifies pathogenic variants in the connexin 31 gene that impair potassium recycling in the inner ear, leading to bilateral sensorineural hearing loss. A definitive molecular diagnosis enables precise genetic counselling, early intervention with hearing aids or cochlear implants, and informed family planning.
2. Can I use a home blood collection service for this genetic test in the UAE?
Yes, our DHA-licensed VIP mobile phlebotomy team collects blood, one-drop FTA card, or extracted DNA at your residence in any emirate between 8 AM and 11 PM, using ISO-certified cold-chain transport to preserve sample integrity.
3. How long do results take, and will I receive clinical guidance afterward?
Results are typically issued within 3–4 weeks; a DHA-licensed genetic counsellor will schedule a complimentary post-test teleconsultation to explain the findings, discuss inheritance patterns, and recommend next steps for clinical management.
