Test Overview & Methodology

This next-generation sequencing (NGS) test analyzes the RRM2B gene for pathogenic variants linked to mitochondrial DNA depletion syndrome type 8B (MNGIE-like phenotype). In the UAE, it provides a definitive molecular diagnosis for suspected mitochondrial neurological disorders with a turnaround time of 3–4 weeks.

Pre-Test Genetic Counseling: A mandatory genetic counselling session is required to draw a detailed pedigree chart of affected family members. This step ensures accurate interpretation of results and ethical compliance with UAE genetic testing regulations.

Physician Insight & Safety Protocols

Lina Osama Zaki Quteineh | Consultant Medical Genetics | DHA Registration ID: 9294403: “The RRM2B genetic test provides a definitive molecular diagnosis for mitochondrial neurogastrointestinal encephalopathy (MNGIE) syndrome. Identifying pathogenic variants in the RRM2B gene allows for targeted metabolic management, surveillance for complications, and informed family planning. Clinical correlation with neurological and gastrointestinal symptoms remains paramount for comprehensive patient care.”

Critical Advisory Statement

This diagnostic test is not a therapeutic intervention. Do not alter or discontinue prescribed medications based solely on the results of this test. All clinical management decisions must be made by the attending physician or specialist. If you are experiencing a medical emergency, including acute metabolic crisis, seizure, or loss of consciousness, proceed to the nearest emergency department immediately.

Safety Exclusion & Clinical Red Flags

Exclusion Criteria: This test is not indicated for acute medical emergencies; requires stable clinical condition for sample collection.
ER Red Flags: Sudden seizure, loss of consciousness, respiratory distress, or metabolic crisis – seek emergency medical care immediately.
Pediatric/Minor Consent: In compliance with Federal Decree-Law No. 4 of 2016 on Medical Liability, a parent or legal guardian must provide informed consent for testing of minors.

Patient FAQ & Clinical Guidance

1. What is the RRM2B gene and what does this test diagnose?

This test detects pathogenic variants in the RRM2B gene using ISO-accredited Next-Generation Sequencing (NGS). It provides a definitive molecular diagnosis for mitochondrial DNA depletion syndrome type 8B, also known as a MNGIE-like phenotype, which affects the neurological and gastrointestinal systems.

2. How is the sample collected for the RRM2B genetic test?

A simple blood draw (3–5 mL in an EDTA tube) or a dried blood spot on an FTA card is collected. Our VIP mobile phlebotomy service operates daily from 8:00 AM to 11:00 PM, using temperature-controlled cold-chain transport to ensure sample stability and full DHA compliance.

3. What is the turnaround time for the results?

The standard turnaround time is 3–4 weeks (21–28 business days) from the date of sample collection. This timeline includes the mandatory pre-test genetic counseling session, comprehensive NGS sequencing, bioinformatic analysis, and clinical validation of any identified variants.

4. Will my insurance cover the cost of this genetic test?

We verify direct billing with your insurer instantly via WhatsApp at +971 54 548 8731 before sample collection. Many UAE insurance policies cover medically indicated advanced genetic diagnostics, though coverage depends on your specific plan and insurer.

5. What does a negative result mean for my condition?

A negative result significantly reduces the likelihood of an RRM2B-related mitochondrial disorder. However, it does not exclude all mitochondrial diseases. Clinical correlation with neurological and metabolic symptoms remains essential. Your consultant medical geneticist will discuss all possible diagnoses and recommend further testing if indicated.
