Test Overview & Methodology
The PHEX Gene Hypophosphatemic Rickets (X‑linked) Genetic Test analyzes all 22 coding exons and flanking intronic regions of the PHEX gene using Next‑Generation Sequencing (NGS) on the Illumina® platform. This approach detects single‑nucleotide variants (SNVs), small insertions/deletions, and copy‑number variants (CNVs) with high sensitivity. Compared to traditional Sanger sequencing, NGS offers comprehensive coverage and higher diagnostic yield, typically exceeding 95% in clinically defined XLH cases.
| Parameter | Our Test (NGS‑Full Gene) | Closest Alternative (Sanger Single‑Exon) |
|---|---|---|
| Methodology | NGS (Illumina® platform) | Sanger sequencing (individual amplicons) |
| Gene Coverage | 22 exons + flanking intronic regions | Limited to preselected exons |
| Variant Classes Detected | SNVs, indels, copy‑number variants (CNV) | SNVs & small indels only |
| Turnaround Time | 3–4 weeks | 4–6 weeks (if multiple exons) |
| Price (AED) | 2800 | Often >3500 when full coverage needed |
| Diagnostic Yield | >95% in clinically defined XLH | 75–85% when limited to hot‑spots |
Physician Insight & Safety Protocols
“A definitive molecular diagnosis of X‑linked hypophosphatemia allows families to make informed decisions about therapy, including phosphate supplementation, active vitamin D analogues, and burosumab. However, results must always be interpreted alongside serum phosphate, FGF23, and renal tubular function. I personally recommend multidisciplinary review for every positive case, and genetic counselling is mandatory before and after testing.”
— Lina Osama Zaki Quteineh, Consultant Medical Genetics, DHA Registration ID: 9294403
Advisory – Medication Safety
Do not discontinue prescribed phosphate supplements, active vitamin D, or burosumab without consulting your treating physician. Abrupt changes can provoke severe metabolic imbalance, including hypocalcemia or phosphate crisis. Always inform the laboratory of current medications prior to sample collection.
Exclusion Criteria & Emergency Red Flags
- Exclusion: Inability to provide a valid venous blood sample or FTA card; active systemic infection requiring immediate medical stabilization.
- Exclusion: Minors must have legal guardian consent as per UAE Federal Decree‑Law No. 4 of 2016 on Medical Liability; unaccompanied minors will not be drawn.
- Red Flag – Seek ER Immediately: Sudden severe bone pain, pathological fractures, acute tetany, or altered consciousness; these may indicate critical hypocalcemia or phosphate crisis.
- Red Flag: Signs of raised intracranial pressure (persistent headache, vomiting, visual changes) in a child with known rickets – urgent neuroimaging required.
Patient FAQ & Clinical Guidance
1. What does the PHEX NGS test detect, and who should consider it?
This NGS test identifies pathogenic single‑nucleotide variants, insertions/deletions, and copy‑number changes across all 22 coding exons of the PHEX gene, enabling definitive diagnosis of X‑linked hypophosphatemic rickets (XLH). It is indicated for individuals with low serum phosphate, renal phosphate wasting, elevated FGF23, or typical skeletal deformities, as well as for at‑risk family members. Genetic counselling and a detailed pedigree chart are mandatory prerequisites before testing.
2. How are samples collected and what is the turnaround time in the UAE?
Sample collection is performed through our VIP Mobile Phlebotomy service (8 AM–11 PM) or at the DNA Labs UAE facility. A single venous blood draw or a drop of blood on an FTA card is obtained by a DHA‑licensed phlebotomist. All samples are transported in ISO‑certified cold‑chain containers. Results are delivered within 3 to 4 weeks. Schedule collection via WhatsApp at +971 54 548 8731. No fasting or medication adjustments are required unless instructed by your doctor.
3. Is this test covered by UAE insurance, and how is my genetic data protected?
Most DHA‑approved insurance plans fully or partially cover the 2800 AED fee when pre‑authorisation is obtained through our direct billing team. All genetic data is safeguarded under 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. Our laboratory adheres to ISO 9001:2015 (Cert: INT/EGQ/2509DA/3139) and we never share identifiable genetic information without explicit consent.
