Test Overview
The GNAT2 gene NGS test scans the entire coding region of the GNAT2 gene to detect pathogenic variants causing complete achromatopsia from birth, guiding precise ophthalmological care and genetic counselling. يفحص الاختبار كامل جين GNAT2 لتحديد الطفرات المسببة لعمى الألوان التام، مما يوجه الرعاية البصرية والاستشارة الوراثية بدقة.

Physician Insight & Safety Protocol
A Note from Dr. Prabhakar Reddy (DHA License: 61713011)
“As an ophthalmologist, I understand that receiving a potential genetic diagnosis for your child's vision can feel overwhelming. This test, when paired with a detailed eye exam and genetic counselling, provides families with the clarity to plan early interventions and supportive care. Please know that a positive result does not limit your child's ability to live a full, meaningful life—support, low-vision aids, and educational resources make a profound difference.”
⚠️ Medication Warning: Do not discontinue any prescribed medication or supplement without consulting your treating physician. This genetic test is intended for diagnostic confirmation and does not replace a comprehensive ophthalmological examination.
Safety Exclusion Criteria & Emergency Red Flags
- Inability to provide informed consent (patient or legal guardian).
- Acute systemic illness or febrile episode within 24 hours of sample collection.
- Recent intraocular surgery (within the last 4 weeks).
- Known bleeding disorders that contraindicate venipuncture (alternative FTA card option available).
🚨 Seek immediate emergency care if you experience: sudden complete vision loss, severe eye pain, intense photophobia with headache, or signs of retinal detachment (flashes/floaters).
Patient FAQ & Clinical Guidance
What is GNAT2 achromatopsia and how is this test performed?
This Genetic Test requires a simple blood draw, a drop of blood on an FTA card, or previously extracted DNA. It utilizes next‑generation sequencing to read every exon of the GNAT2 gene, identifying even rare pathogenic variants linked to the complete inability to perceive color from birth.
يقوم اختبار التسلسل الجيني بتحليل كامل جين GNAT2 من عينة دم أو حمض نووي للكشف عن الطفرات المسببة لعمى الألوان التام من النوع الرابع، بدقة تصل إلى 99.9%.
Do I need genetic counselling before taking this test?
A pre‑ genetic counselling session is mandatory to draw a detailed pedigree chart and discuss the implications of GNAT2 gene mutations for family planning. Our certified genetic counsellor will review your family history, explain autosomal recessive inheritance, and obtain informed consent before sample collection. This session ensures you fully understand the results, reproductive options, and the importance of sharing findings with at‑risk relatives.
جلسة الاستشارة الوراثية قبل الاختبار إلزامية لرسم شجرة العائلة ومناقشة دلالات طفرات جين GNAT2 الوراثية وتأثيرها على تنظيم الأسرة.
How long do results take and who will interpret them?
Results are available within 3 to 4 weeks, and an ophthalmologist or clinical geneticist will provide a telephonic interpretation session to explain your report. You will receive a comprehensive PDF report highlighting any pathogenic variants, a clinical correlation, and recommendations for follow‑up eye examinations. Emergency findings are communicated immediately.
تتوفر النتائج خلال 3 إلى 4 أسابيع، وسيقوم طبيب عيون أو أخصائي وراثة سريرية بتقديم جلسة تفسير هاتفية لشرح التقرير وتوصيات المتابعة.
