Test Overview & Methodology
This next‑generation sequencing (NGS) test analyzes the entire CHN1 gene to detect pathogenic variants responsible for Duane retraction syndrome (DURS1). It offers definitive molecular confirmation for affected individuals and family members, enabling precise genetic counseling and early ophthalmological intervention.
| Feature | Our CHN1 NGS Test | Closest Alternative (Single‑Gene Sanger) |
|---|---|---|
| Precision | 100x average read depth, full gene coverage – detects SNVs, indels, CNVs | Sequencing of exons only, lower sensitivity for deep intronic variants |
| Method | NGS with orthogonal Sanger confirmation of all clinically significant variants | Sanger sequencing alone; no CNV detection capability |
| Turnaround Time | 3 to 4 Weeks | 4 to 6 Weeks |
Physician Insight & Safety Protocols
"The CHN1 gene test provides a crucial genetic diagnosis for Duane retraction syndrome, empowering families with accurate recurrence risks and guiding personalized ophthalmological care. I recommend that all results be discussed with a specialized genetic counselor to fully understand the implications."

Important Advisory
⚠️ Medication Warning
Do not alter or discontinue any prescribed medications without prior consultation with your treating physician. This genetic test does not replace ongoing medical management.
Patient Safety Exclusion Criteria & Emergency Red Flags
Exclusion Criteria
- Active eye infection or recent ocular trauma (sample collection may be postponed).
- Inability to provide informed consent or complete a pre‑test genetic counseling session.
- Known hypersensitivity to antiseptics used during phlebotomy.
- Emergency Red Flags: Sudden vision loss, acute eye pain, or double vision with nausea – seek immediate ER care; genetic testing is not an emergency procedure.
Patient FAQ & Clinical Guidance
1. What is the CHN1 genetic test for Duane retraction syndrome and how accurate is it?
This DNA analysis identifies pathogenic variants in the CHN1 gene causing Duane syndrome with 99.9% diagnostic sensitivity. The test uses next‑generation sequencing to cover all coding regions and splice sites, providing definitive molecular diagnosis.
2. Is home sample collection available in all Emirates and what are the costs?
Yes, we offer ISO‑certified cold‑chain home collection across all UAE emirates including Dubai, Abu Dhabi, Sharjah, and the Northern Emirates. VIP Mobile Phlebotomy is available daily from 8 AM to 11 PM. The service is included in the 2,800 AED test price for patients residing within the coverage area.
3. Will my genetic data be kept confidential under UAE law?
Your data is protected 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. All genetic information is encrypted, stored in DHA‑licensed facilities, and never shared without your explicit consent.
