Test Overview & Methodology
The LARS2 Gene NGS Test identifies pathogenic variants in LARS2 causing Perrault syndrome type 4, a mitochondrial disorder leading to sensorineural hearing loss, ovarian failure, and neurological signs.
Pre-Test Requirements
A detailed clinical history must be provided. A genetic counselling session to draw a family pedigree of individuals affected by or suspected of LARS2-related Perrault syndrome type 4 is mandatory. No special fasting or medication adjustments are required, but please continue all prescribed treatments unless instructed otherwise by your physician.
| Feature | Our Test – LARS2 NGS | Closest Alternative (Whole Exome Sequencing) |
|---|---|---|
| Diagnostic Precision | 99.9% sensitivity for LARS2 variants; targeted single‑gene depth >500x | Variable coverage; risk of missing deep intronic variants; incidental findings burden |
| Methodology | Next Generation Sequencing (NGS) – Illumina NovaSeq with Sanger validation | Whole Exome Sequencing (WES) – broad genomic approach |
| Turnaround Time | 3 to 4 Weeks | 6 to 8 Weeks |
| Sample Requirements | Blood, Extracted DNA, or One-Drop Blood on FTA Card | Blood (minimum 3 ml) |
Physician Insight & Safety Protocols
Lina Osama Zaki Quteineh (Consultant Medical Genetics, DHA ID: 9294403): “Our targeted NGS approach for LARS2 provides precise genetic answers for families affected by Perrault syndrome. Each result must be interpreted within the full clinical context, and we are committed to guiding every patient with clarity and support.”
Medication Warning
Do not discontinue prescribed medication without consulting your doctor. Abrupt changes may worsen neurological or hormonal status.
Exclusion Criteria & Emergency Red Flags
- Specimens that are haemolysed, clotted, or improperly stored (cold chain breach) cannot be processed.
- Minors require explicit, written informed consent compliant with Federal Decree-Law No. 4 of 2016 on Medical Liability and a legal guardian’s presence.
- Seek immediate emergency care if you experience sudden neurological deterioration (profound weakness, loss of consciousness, seizure) – do not wait for test results.
- Active febrile illness or severe infection may interfere with sample quality; schedule after recovery.
Patient FAQ & Clinical Guidance
1. How accurate is the LARS2 gene test for diagnosing Perrault syndrome type 4?
Our targeted NGS assay offers 99.9% diagnostic sensitivity and near‑100% specificity for LARS2 pathogenic variants, validated by ISO 15189 accredited laboratories and confirmed with Sanger sequencing.
2. Can this DNA test be performed on home-collected samples, and how is the cold chain maintained?
Yes, our VIP home collection service uses ISO‑certified cold‑chain kits with temperature monitors; a licensed phlebotomist arrives within 90 minutes, ensuring sample integrity from your door to our lab.
3. What genetic counselling support is included after receiving my LARS2 result?
A DHA-licensed genetic counsellor provides a complimentary 30‑minute telehealth session to interpret results, discuss implications for family members, and coordinate further neurological or reproductive follow‑up.
