RPGRIP1L Gene Joubert Syndrome Type 7 Genetic Test in UAE | 2800 AED | 2026 DHA Guidelines
تحليل جين RPGRIP1L لفحص متلازمة جوبير النوع 7 في الإمارات | 2800 درهم | إرشادات هيئة الصحة بدبي 2026
Executive Clinical Summary: This UAE-based diagnostic panel leverages Next‑Generation Sequencing (NGS) to detect pathogenic variants in the RPGRIP1L gene causative of Joubert syndrome type 7—a rare ciliopathy with hallmark brain malformations and developmental delay. The test offers 99.9% diagnostic sensitivity under ISO 9001:2015‑accredited processing (Cert: INT/EGQ/2509DA/3139), enabling definitive molecular diagnosis for timely neurological intervention and family planning.
Clinical Overview & Test Comparison
The RPGRIP1L Gene NGS Test is a comprehensive molecular diagnostic tool that screens the entire coding region of the RPGRIP1L gene for single‑nucleotide variants, small indels, and copy number changes associated with Joubert syndrome type 7 (JBTS7). It serves as a definitive confirmation assay for infants and children presenting with the molar tooth sign on neuroimaging, hypotonia, and oculomotor apraxia. Below, we compare our UAE‑optimised NGS platform with the most common alternative diagnostic approach.
| Feature | Our NGS Test (UAE) | Standard Sanger Sequencing / Panel |
|---|---|---|
| Method | Next‑Generation Sequencing (NGS) – full gene analysis | Sanger sequencing of selected exons / limited gene panel |
| Diagnostic Sensitivity | 99.9% | 85–90% (may miss deep intronic or copy number variants) |
| Turnaround Time | 3 to 4 Weeks | 6–8 Weeks |
| Comprehensive CNV Detection | Yes – integrated bioinformatics pipeline | Often requires separate MLPA assay |
| Price (AED) | 2,800 | 2,200–3,500 (variable, incomplete coverage) |
Physician Insight & Safety Protocol
“As a Clinical Neurogeneticist licensed by the Dubai Health Authority (DHA 61713011), I appreciate the weight of seeking a genetic answer for a child with suspected Joubert syndrome. This advanced NGS test can provide the molecular confirmation that guides multidisciplinary care, but a negative result does not exclude all genetic disorders—clinical correlation with MRI findings and specialist evaluation remains essential. Always involve a certified genetic counsellor when interpreting results.”

⚠️ Medication Safety Notice
Do not discontinue any prescribed medication (anti‑epileptics, respiratory support, etc.) without consulting your attending physician. This genetic test is for diagnostic clarification only and does not replace acute medical management.
Exclusion Criteria: This test is inappropriate for individuals who have received a whole‑blood transfusion or allogeneic bone marrow transplant within the last 6 weeks (donor DNA may interfere). For patients on chronic immunosuppression, please discuss with our laboratory.
🚨 Emergency Red Flags: If the patient experiences new‑onset seizures, sudden loss of consciousness, or severe respiratory difficulty, do not wait for test results—seek immediate emergency medical attention.

Frequently Asked Questions (English & Arabic)
Q1: What exactly does the RPGRIP1L gene test detect, and who should consider it?
Our NGS test identifies pathogenic variants across the entire RPGRIP1L gene that cause Joubert syndrome type 7, a rare neurological ciliopathy. It is clinically indicated for infants and young children presenting with cerebellar vermis hypoplasia (molar tooth sign), hypotonia, abnormal eye movements, and developmental delay. A paediatric neurologist or clinical geneticist typically orders the test following abnormal cranial MRI findings.
س1: ما هو اختبار جين RPGRIP1L ومن يجب أن يفكر في إجرائه؟
يكتشف اختبار التسلسل الجيني من الجيل التالي التغيرات الممرضة في جين RPGRIP1L المسؤولة عن متلازمة جوبير النوع 7. يُوصى به للرضع والأطفال الذين تظهر عليهم علامات تشكل "السن الضرسي" في التصوير بالرنين المغناطيسي، وضعف التوتر العضلي، واضطرابات حركة العين، وتأخر النمو. يُطلب الاختبار من قبل طبيب أعصاب أطفال أو استشاري وراثة سريرية بعد الفحوصات العصبية.
Q2: How accurate is this test, and can it predict the severity of Joubert syndrome?
With a diagnostic sensitivity of 99.9% using ISO‑accredited NGS technology, this assay reliably detects single nucleotide variants, indels, and copy number changes. However, genotype‑phenotype correlation in Joubert syndrome is complex; the same gene mutation can lead to a wide spectrum of clinical severity. The report interprets the pathogenicity based on ACMG guidelines and provides a risk assessment for family members, but it cannot precisely forecast individual motor or cognitive outcomes.
س2: ما مدى دقة هذا الاختبار وهل يمكنه التنبؤ بشدة متلازمة جوبير؟
بدقة تشخيصية تصل إلى 99.9%، يكتشف الاختبار بدقة الطفرات النقطية والحذف والإضافة والتغيرات في عدد النسخ. لكن العلاقة بين الطفرة الجينية وشدة الأعراض معقدة؛ فقد تؤدي نفس الطفرة إلى تباين كبير في الأعراض. يقدم التقرير تفسيرًا للإمراضية وفقًا لإرشادات ACMG ويُقيم المخاطر للأقارب، دون التنبؤ الدقيق بالنتائج الحركية أو الإدراكية المستقبلية.
Q3: What type of sample is needed, and how long will it take to get my results?
A simple blood draw (3 mL in EDTA tube), extracted DNA, or a single drop of blood on a specially designed FTA card is sufficient for this analysis. Our trained mobile phlebotomist will arrive at your home or clinic in a cold‑chain‑equipped vehicle. Once the sample reaches our accredited laboratory, the final genetic report is released within 3 to 4 weeks. A telephonic interpretation session with a clinical genetics counsellor is included at no extra cost.
س3: ما نوع العينة المطلوبة وكم يستغرق الحصول على النتائج؟
يمكن استخدام عينة دم كامل (3 مل في أنبوب EDTA)، أو حمض نووي مستخلص مسبقًا، أو نقطة دم واحدة على بطاقة FTA خاصة. يأتي أخصائي سحب العينات المتنقل إلى منزلك بسيارة مجهزة بسلسلة تبريد معتمدة. بعد استلام المختبر للعينة، تُصدر النتائج النهائية خلال 3 إلى 4 أسابيع. تشمل الخدمة استشارة هاتفية مجانية مع مستشار وراثي لتفسير التقرير.
Pre‑Test Requirement:
Before sample collection, a genetic counselling session is mandatory to document the family pedigree of individuals affected by Joubert syndrome type 7 and to obtain informed consent. Our team will arrange a virtual pre‑ consultation at your convenience.
