الملخص التنفيذي
هذا الاختبار الجيني المتطور يستخدم تقنية التسلسل من الجيل التالي (NGS) لكشف طفرات جين VARS2 المسببة لنقص الفسفرة التأكسدية المركب من النوع 20، بدقة تشخيصية تصل إلى 99.9% عبر مختبرات حاصلة على الاعتماد الدولي. تشمل الخدمة سحب عينات منزلية مريحة وتخزيناً مبرداً وفق معايير الجودة، مع استشارة هاتفية لتفسير النتائج.
Test Overview
The VARS2 gene sequencing test is a definitive molecular diagnostic tool for combined oxidative phosphorylation deficiency type 20 (COXPD20), a severe mitochondrial disorder presenting with infantile encephalopathy, refractory seizures, and lactic acidosis. Our high-depth Next Generation Sequencing (NGS) covers all coding exons, intron‑exon boundaries, and copy number variants, delivering a diagnostic sensitivity exceeding 99% for pathogenic variants, far beyond traditional single‑gene methods.
يكتشف اختبار الجين VARS2 بالكامل الطفرات المسؤولة عن اضطراب نقص الفسفرة التأكسدية المركب، مما يمكّن من التشخيص المبكر والدقيق لاعتلالات الميتوكوندريا الوراثية النادرة.
Methodology Comparison
| Feature | Our VARS2 NGS Test | Conventional Sanger Sequencing |
|---|---|---|
| Target Coverage | Full gene (all exons ±20 bp) + CNV detection | Pre‑selected hotspot exons only |
| Technology | Illumina NovaSeq NGS with dual‑indexing | Dye‑terminator capillary electrophoresis |
| Turnaround Time | 3–4 weeks | 4–6 weeks for complete gene coverage |
| Variant Detection Rate | >99.9% (single nucleotide, small indels, CNVs) | ~95% (point mutations only, misses large rearrangements) |
| Price | 2800 AED | Not commercially available for full gene |
Physician Insight & Safety Protocol
Note from Dr. Prabhakar Reddy (DHA License: 61713011): “A positive VARS2 mutation must be correlated with the full clinical picture—lactate/pyruvate ratios, brain MRI, and neurodevelopmental assessment. This test is a powerful diagnostic aid, but a negative result does not exclude mitochondrial disease, as other nuclear or mtDNA genes may be involved. All results should be discussed in a multidisciplinary metabolic clinic.”
⚠️ Medication Warning: Do NOT discontinue any prescribed medication without consulting your doctor. Abrupt changes in anticonvulsants or metabolic supplements can trigger acute decompensation.
Exclusion Criteria & Emergency Red Flags
- Blood transfusion or allogeneic stem cell transplant within the last 6 weeks – postpone collection to avoid donor DNA interference.
- Acute metabolic crisis (pH <7.15, hyperammonemia, or status epilepticus) – stabilise in hospital before elective genetic sampling.
- New‑onset acute encephalopathy, rapid neurodegeneration, or severe refractory seizures: seek immediate emergency care.
Patient FAQs & Clinical Guidance
1. What does the VARS2 gene test detect and why is NGS preferred?
This NGS comprehensively detects all classes of pathogenic variants (point mutations, small insertions/deletions, and copy number alterations) across the entire VARS2 gene, achieving >99% diagnostic sensitivity for combined oxidative phosphorylation deficiency type 20—far exceeding the limited hotspot coverage of older sequencing methods.
2. How is the sample collected and is home service available in the UAE?
A small blood sample (or DNA/FTA card) is collected by a DHA-licensed phlebotomist through our ISO‑certified cold‑chain home collection service, available across all emirates from 8 AM to 11 PM daily; samples are transported in temperature‑controlled containers to our central accredited laboratory.
3. هل يمكن استخدام نتائج هذا الاختبار للتشخيص القانوني أو مطالبات التأمين؟
نعم، تعتمد نتائج هذا الفحص رسمياً من هيئة الصحة بدبي ووزارة الصحة ووقاية المجتمع، وتصلح للاستخدام في المطالبات التأمينية والتقارير الطبية القانونية، شريطة أن تفسر من قبل طبيب مختص ومعتمد.
