Test Overview & Methodology
This comprehensive next-generation sequencing (NGS) test analyzes the entire coding region and splice sites of the GJA8 gene to detect mutations associated with cataract-microcornea syndrome, a rare congenital disorder characterized by bilateral cataracts and abnormally small corneas. This test is essential for pediatric diagnosis, pre-surgical planning, and informed family genetic counseling.
| Feature | Our Test (GJA8 NGS) | Closest Alternative (Sanger Sequencing) |
|---|---|---|
| Methodology | Next Generation Sequencing (NGS) – all coding exons & splice sites | Sanger sequencing – typically limited to exon 2 |
| Turnaround Time | 3 – 4 Weeks | 6 – 8 Weeks |
| Detection Rate | >99% of known pathogenic variants | ~70% (misses deep intronic & regulatory variants) |
| Sample Options | Blood / Buccal Swab / FTA Card | Blood only |
| Price (AED) | 2,800 | 3,500 |
Physician Insight & Safety Protocols
Lina Osama Zaki Quteineh (DHA Registration ID: 9294403, Consultant Medical Genetics): “As a Consultant Medical Genetics, I recognize the profound impact of a definitive molecular diagnosis for families navigating congenital cataract-microcornea syndrome. This advanced NGS analysis provides a precise genetic roadmap, enabling timely surgical interventions, accurate prognostic assessments, and informed family planning. A positive result is not a limitation—it is a compass for proactive, compassionate, and personalized care.”
Clinical Safety & Patient Consent Framework
This clinical service operates strictly under the provisions of Federal Decree-Law No. 4 of 2016 on Medical Liability, ensuring all procedures are conducted with the highest standards of patient safety and informed consent. Our genetic counselors ensure that patients and guardians fully understand the scope, benefits, and implications of genetic testing before proceeding.
Safety Considerations & Exclusion Criteria
- Not for emergency diagnosis. Seek immediate medical attention for acute vision loss, severe eye pain, or ocular trauma.
- Exclusion: Active systemic infection, severe anaemia, or inability to provide a safe venous sample. Minors require legal guardian consent.
- Results must be interpreted by a clinical geneticist or ophthalmologist. Incidental findings may arise and will be communicated per UAE PDPL guidelines.
Patient FAQ & Clinical Guidance
1. What is the GJA8 genetic test and what does it detect?
This test detects pathogenic variants in the GJA8 gene responsible for cataract-microcornea syndrome. It delivers a diagnostic sensitivity exceeding 99% by utilizing comprehensive next-generation sequencing (NGS) to analyze the entire coding region of the gene.
2. How is the sample collected for this genetic test in the UAE?
A certified phlebotomist visits your home between 8 AM and 11 PM to draw a small blood sample using a cold-chain transport kit. Alternatively, you may opt for a non-invasive buccal swab or an FTA card if venipuncture is challenging.
3. What is the turnaround time and how will I receive my results?
The standard turnaround time is 3 to 4 weeks from the date the sample is received in our laboratory. Results will be explained in detail during a dedicated telephonic consultation with our Consultant Medical Geneticist, and a confidential digital report will be provided.
UAE Regulatory & Data Privacy Adherence
DNA Labs UAE strictly adheres to Federal Decree-Law No. 45 of 2021 on Personal Data Protection (PDPL) and Federal Law No. 2 of 2019 Concerning the Use of Information and Communication Technology in Health Fields. All genetic data is handled with the highest level of confidentiality and security, ensuring complete patient privacy and full regulatory compliance.
