Test Overview & Methodology
This advanced genetic test sequences the entire AQP2 gene using Next-Generation Sequencing (NGS) to identify pathogenic variants causing hereditary nephrogenic diabetes insipidus (autosomal recessive or dominant). It is the definitive molecular diagnosis for patients presenting with polyuria, polydipsia, and hypernatremia of renal origin. A comprehensive clinical history focusing on polyuria onset and a family pedigree are drawn during a mandatory genetic counselling session prior to sample collection.
| Feature | Our AQP2 Genetic Test | Sanger Sequencing (Closest Alternative) |
|---|---|---|
| Methodology | Full gene NGS (Next-Generation Sequencing) | Targeted single-exon Sanger sequencing |
| Detection Power | Detects known and novel variants across all exons & splice sites | Limited to pre-specified mutation hotspots; misses novel variants |
| Turnaround Time | 3โ4 Weeks | 4โ6 Weeks |
| Clinical Sensitivity | 99.9% for coding region mutations | ~80% (misses deep intronic/novel changes) |
| Price (AED) | 2,800 | 2,500 โ 3,200 |
Physician Insight & Safety Protocols
Lina Osama Zaki Quteineh โ Consultant Medical Genetics (DHA Registration ID: 9294403): โEvery case of suspected nephrogenic diabetes insipidus deserves a thorough genetic evaluation to guide family counselling and avoid unnecessary vasopressin trials. This NGS test will reveal whether an AQP2 mutation underlies the resistance, but always correlate molecular findings with a detailed fluid balance chart and serum sodium levels. I strongly recommend involving a nephrologist or endocrinologist before acting on results.โ
Advisory: Medication & Clinical Management
โ ๏ธ Medication Advisory
Do not discontinue prescribed medication (e.g., thiazides, amiloride) without consulting your doctor. Abrupt interruption can trigger severe electrolyte imbalances.
Exclusion Criteria & Emergency Red Flags
- Exclusion: Inability to provide a valid blood specimen; lack of pre-test genetic counselling and signed informed consent.
- Exclusion (Minors): Testing strictly follows UAE regulatory frameworks โ guardian consent and paediatric specialist referral are mandatory.
- ER Red Flags: If the patient develops severe dehydration, intractable vomiting, altered consciousness, or sodium >155 mmol/L, seek immediate emergency care.
- Clinical Safety: All procedures are governed by Federal Decree-Law No. 4 of 2016 on Medical Liability, ensuring patient consent and safety are prioritised.
Patient FAQ & Clinical Guidance
1. What does the AQP2 gene test detect?
Direct Answer: It detects pathogenic variants in the entire AQP2 gene that cause hereditary nephrogenic diabetes insipidus, explaining congenital polyuria and polydipsia.
2. How is the test performed and how long does it take?
Direct Answer: A blood sample is collected at home by a VIP mobile phlebotomist under temperature-controlled cold-chain logistics. DNA is extracted and NGS is performed, with results available in 3โ4 weeks.
3. Is genetic counselling necessary before testing?
Direct Answer: Yes, a mandatory pre-test genetic counselling session is required to draw a family pedigree and discuss the implications for relatives. This is conducted by our Consultant Medical Geneticist.
4. Can I proceed directly with the blood draw without prior counselling?
Direct Answer: No. Informed consent and pre-test counselling are mandatory under UAE Federal Decree-Law No. 4 of 2016. The counselling session ensures you understand the scope and implications of the genetic analysis.
5. Are my genetic data protected by UAE privacy laws?
Direct Answer: Yes. All genetic data are processed under Federal Decree-Law No. 45 of 2021 on Personal Data Protection (PDPL) and Federal Law No. 2 of 2019 concerning ICT in health fields. Your data remain strictly confidential.
