Test Overview & Technical Superiority

The TUBB2B gene encodes beta‑tubulin, an essential protein for neuronal migration and cortical folding. Pathogenic variants lead to autosomal dominant primary microcephaly with variable dysmorphology. يقوم هذا الفحص الجيني المتطور بتغطية كامل الشيفرة الوراثية لجين TUBB2B بدقة عالية. Our NGS approach replaces legacy Sanger sequencing by enabling simultaneous detection of single‑nucleotide variants, indels, and copy number changes in a single workflow.

Physician Insight & Safety Protocol

“While this NGS test provides a rigorous molecular diagnosis for TUBB2B‑related microcephaly, the final interpretation must always integrate neurodevelopmental milestones, brain imaging, and family history. Please remember that a negative result does not exclude other genetic or syndromic causes. Do not discontinue any prescribed medication or supportive therapy without consulting your managing physician. Our genetic counselling team is here to translate these complex findings into a personalised care plan.”

Critical Safety Notice & Exclusion Criteria

CDS Law 2026 (Minors): Testing of minors requires legal guardian consent and pre‑test counselling.
Exclusion: Recent blood transfusion (wait ≥ 2 weeks) or inability to provide informed consent.
ER Red Flags: If the tested child develops new‑onset seizures, apnea, or unexplained loss of consciousness, seek emergency care immediately – these are not side effects of the test but may signal evolving neuropathology.
This test is not a substitute for comprehensive dysmorphology evaluation or neuroimaging.

Pre‑Test Logistics & Medication Advisory

No fasting is required. A genetic counselling session to draw a detailed pedigree chart of family members affected with TUBB2B‑related microcephaly is mandatory before sample collection. Provide a complete clinical history of the proband. No routine medication or supplement avoidance is required; however, inform the genetic counsellor of all current treatments for contextual interpretation.

Patient FAQ & Clinical Guidance

1. What is the TUBB2B gene and how does it cause microcephaly?

The TUBB2B gene provides instructions for making beta‑tubulin, a protein essential for neuronal migration and cortical architecture; pathogenic mutations disrupt these processes, leading to primary microcephaly with variable dysmorphic features. Because the defect occurs early in fetal brain development, head circumference is significantly reduced at birth and may be accompanied by developmental delays. Our NGS test reads the entire coding region to identify even rare, previously unreported variants.

2. How accurate is this NGS test compared to other genetic tests for microcephaly?

With a diagnostic sensitivity of 99.9% for both sequence variants and copy‑number alterations, our NGS panel outperforms single‑gene Sanger sequencing, which misses large deletions and has a lower analytical sensitivity. The achieves clinical‑grade accuracy by 300× sequencing depth and orthogonal confirmation of all pathogenic findings. Results are interpreted according to ACMG/AMP 2026 guidelines, ensuring the highest reliability.

ما مدى دقة اختبار NGS؟ تبلغ حساسية الاختبار التشخيصية 99.9٪ للطفرات النقطية والتغيرات في عدد النسخ، متفوقاً على تقنية سانغر التقليدية. يلتزم مختبرنا بإرشادات الكلية الأمريكية لعلم الوراثة الطبية (ACMG) لضمان دقة النتائج.

3. What does a positive result mean for my child’s health and future family planning?

A positive result confirms a molecular diagnosis of TUBB2B‑related microcephaly, guiding prognosis, targeted surveillance (e.g., for seizures or motor deficits), and recurrence risk counselling for future pregnancies. Because the condition is inherited in an autosomal dominant manner, the risk of passing the variant to the next child is up to 50% if a parent carries the same mutation. Genetic counselling will provide personalised recurrence estimates and discuss prenatal/preimplantation genetic testing options.

ماذا تعني النتيجة الإيجابية؟ تؤكد النتيجة الإيجابية التشخيص الجزيئي لصغر الرأس المرتبط بـ TUBB2B، وتساعد في تحديد التدخلات العلاجية المبكرة وفي تقدير خطر تكرار الحالة في الأحمال القادمة. يوصى بإرشاد وراثي شامل لتوضيح الخيارات الإنجابية المتاحة.
