COL15A1 Gene Early-Onset Glaucoma, Phenotype Modifier, COL15A1‑Related Genetic Test in UAE | 2800 AED | 2026 DHA Guidelines

Overview

This next‑generation sequencing (NGS) test thoroughly examines the entire coding region of the COL15A1 gene to identify pathogenic variants associated with early‑onset glaucoma and its phenotypic modifier effects. Delivered in 3–4 weeks, it empowers precise risk stratification, informing tailored surveillance and intervention plans for you and at‑risk relatives.

يقوم هذا التحليل المتقدم بتسلسل كامل الجين COL15A1 لكشف الطفرات المسببة للجلوكوما المبكرة، مما يساعد في تقييم المخاطر الوراثية واتخاذ القرارات العلاجية المناسبة.

1. What is the COL15A1 gene and its role in glaucoma?

Snippet: The COL15A1 gene encodes collagen type XV alpha‑1 chain, essential for maintaining ocular basement membrane integrity and intraocular pressure regulation. يشفر جين COL15A1 بروتين الكولاجين من النوع الخامس عشر ألفا-1، الضروري لسلامة الغشاء القاعدي العيني وتنظيم ضغط العين. Pathogenic variations disrupt the extracellular matrix of the trabecular meshwork and retina, predisposing carriers to early‑onset open‑angle glaucoma. This NGS test clarifies your molecular diagnosis and guides cascade screening of family members.

2. How is the test performed and what preparation is required?

Snippet: A simple blood draw or DNA sample collection requires no fasting or special preparation; the entire process is pain‑less and home‑based. سحب عينة دم بسيط أو عينة حمض نووي لا يحتاج صياماً أو تحضيرات خاصة، ويمكن إجراؤه في المنزل. Our certified phlebotomists arrive at your location between 8 AM and 11 PM with cold‑chain transport kits. You must attend a pre‑test genetic counselling session (telephonic or in‑person) to draw a pedigree chart and discuss the implications. The laboratory then extracts DNA from whole blood, dried blood spots (FTA card), or previously extracted DNA, sequencing all COL15A1 exons via NGS technology.

3. What does a positive result mean for me and my family?

Snippet: A pathogenic variant in COL15A1 indicates increased risk for early‑onset glaucoma, not a definitive diagnosis; clinical correlation is mandatory. وجود طفرة مرضية في جين COL15A1 يشير إلى زيادة خطر الإصابة بالجلوكوما المبكرة، وليس تشخيصاً قاطعاً؛ لذا المتابعة السريرية ضرورية. The result pinpoints your lifetime predisposition; however, many mutation carriers never develop advanced disease. We recommend sharing the report with a glaucomatologist for a tailored surveillance plan (e.g., annual optical coherence tomography, visual field testing). First‑degree relatives may undergo predictive testing only after appropriate genetic counselling, respecting UAE PDPL and Federal Decree‑Law No. 41 of 2024 (Art. 87) data privacy safeguards. For minors, CDS Law 2026 mandates parental consent and clinical necessity assessment.
