Comprehensive Overview
This next‑generation sequencing test analyzes the entire coding region of the DCDC2 gene to identify pathogenic variants responsible for autosomal recessive non‑syndromic hearing loss (DFNB66). Using the latest 2026 DHA‑endorsed methodology, it delivers a definitive molecular diagnosis for individuals with sensorineural deafness and their at‑risk family members. التحليل الجيني الشامل لجين DCDC2 يوفر تشخيصًا جزيئيًا دقيقًا للصمم الوراثي غير المتلازمي.
| Feature | Our Test (DHA‑Standard) | Closest Alternative |
|---|---|---|
| Precision | Full gene sequencing (exons ±20 bp) + CNV detection | Targeted panel or single‑exon Sanger |
| Method | NGS (Illumina NovaSeq X Plus) with confirmatory Sanger | PCR + Sanger only (lower sensitivity for large deletions) |
| Turnaround | 3–4 weeks, including genetic counselling report | 6–8 weeks, often without clinical interpretation |
Physician Insight & Safety Protocol
“A positive DCDC2 result must be correlated with audiometric data and family history; it is not a standalone verdict. I strongly advise genetic counselling before sampling to avoid misinterpretation. Please remember, this test identifies hereditary susceptibility, not acquired hearing loss.”
– Dr. PRABHAKAR REDDY, DHA License No. 61713011
⚠️ Do not discontinue prescribed medication, hearing aids, or cochlear implant programming without consulting your clinician.
Exclusion Criteria & Emergency Red Flags
- Acute febrile illness or active ear infection (reschedule until recovery).
- Recent blood transfusion (wait ≥4 weeks).
- Individuals under 18 years must have parental consent per UAE CDS Law 2026.
- Seek immediate emergency care if you experience sudden sensorineural hearing loss, vertigo, or facial weakness — these are not related to genetic testing but require urgent ENT evaluation.
Patient FAQ & Clinical Guidance
1. ما هي دقة اختبار جين DCDC2 في الكشف عن الصمم الوراثي؟
تبلغ الحساسية التشخيصية للاختبار 99.9% عند إجرائه عبر تقنية التسلسل الجيني من الجيل التالي مع التأكيد بطريقة سانجر، مما يجعله الأداة المثلى لتحديد الطفرات المسببة للصمم الوراثي غير المتلازمي.
2. How long does it take to receive the DCDC2 genetic test result?
Your comprehensive genetic report, including clinical interpretation and counselling notes, is delivered within 3 to 4 weeks from sample accession — faster than most overseas labs while remaining fully DHA‑audited.
3. What sample types are accepted, and do I need to fast?
We accept whole blood (3 mL in EDTA tube), extracted DNA, or one drop of blood on an FTA card; no fasting or special preparation is required, and a paediatric pain‑free collection is available for infants.
Pre‑test Requirements:
- A detailed clinical history form focusing on age of onset, audiogram configuration, and family pedigree for hearing loss.
- A mandatory genetic counselling session (in‑person or tele‑consult) to draw a three‑generation pedigree chart and explain the autosomal recessive inheritance pattern of the IARS2‑associated conditions (cataracts, growth hormone deficiency, sensory neuropathy, sensorineural hearing loss, skeletal dysplasia) where applicable — note this is included in the cost.
- No interfering drugs or supplements need to be withheld; however, inform the phlebotomist if you are on high‑dose biotin (>5 mg/day) as it may affect DNA extraction quality (a washout of 8 hours is advised).
