Test Overview & Methodology
The TCN2 gene test utilizes Next-Generation Sequencing (NGS) to detect pathogenic variants in the Transcobalamin II gene, a critical transporter of vitamin B₁₂. This test provides definitive diagnosis for Transcobalamin II deficiency, an autosomal recessive metabolic disorder, enabling early intervention and personalized management.
| Feature | Our Test (NGS) | Standard Single-Gene Sanger |
|---|---|---|
| Methodology | Next-Generation Sequencing (full gene coverage) | Sanger sequencing (targeted regions only) |
| Analytical Sensitivity | >99.9% (SNVs, indels, CNVs) | ~98% (limited to predefined amplicons) |
| Turnaround Time | 3–4 Weeks (UAE referral lab) | 6–8 Weeks (often outsourced internationally) |
Physician Insight & Safety Protocols
Clinical Note from Ms. Lina Osama Zaki Quteineh (DHA Registration ID: 9294403, Consultant Medical Genetics): "A positive test should always be correlated with biochemical markers such as elevated methylmalonic acid and homocysteine levels, and with clinical presentation. Genetic counselling is mandatory before testing to interpret variants in the context of family history and consanguinity."
⚠️ Medication & Urgent Care Advisory
Do not discontinue prescribed medication (including vitamin B₁₂ injections) without consulting your doctor.
Exclusion Criteria: This test should not be ordered as a standalone screening tool in asymptomatic individuals without a positive family history or clinical indication.
Emergency Red Flags: If you experience severe pallor, tachycardia, shortness of breath, or neurological symptoms (confusion, numbness), seek immediate medical attention. These may indicate decompensated anemia or metabolic crisis.
Patient FAQ & Clinical Guidance
1. What does the TCN2 gene test diagnose?
The TCN2 gene test identifies inherited pathogenic variants causing Transcobalamin II deficiency, a treatable genetic disorder of vitamin B₁₂ transport. Early diagnosis through NGS enables timely intervention with hydroxocobalamin therapy and prevents irreversible neurological damage.
2. How long does it take to receive results in the UAE?
Our accredited NGS workflow delivers a comprehensive clinical report within 3 to 4 weeks, including genetic counselling interpretation and DHA-compliant documentation. The report details all detected variants, their pathogenicity classification, and clinical recommendations.
3. Is home sample collection available, and what sample types are accepted?
Yes, ISO-certified VIP mobile phlebotomy is available daily from 8 AM to 11 PM for blood samples (whole blood in EDTA tube) or extracted DNA samples. A single dried blood spot on an FTA card is also accepted. All samples are transported via temperature-controlled cold-chain logistics.
