Test Overview & Methodology
WNT7A gene sequencing detects pathogenic variants causing the rare limb malformation spectrum: fibular aplasia/hypoplasia, femoral bowing, and poly-/syn-/oligodactyly. This genetic test guides early surgical planning, genetic counselling, and family risk assessment.
| Feature | Our Test (NGS) | Closest Alternative |
|---|---|---|
| Precision | Single‑nucleotide resolution, full gene coverage | Sanger sequencing (single exon/ candidate variant only) |
| Methodology | Next‑Generation Sequencing (Illumina® platform) with confirmed variant calling | Targeted mutation analysis by PCR‑RFLP |
| Turnaround Time | 3–4 weeks | 6–8 weeks |
Physician Insight & Safety Protocols
Note from Lina Osama Zaki Quteineh (Consultant Medical Genetics, DHA: 9294403)
“An abnormal WNT7A result alone is not a diagnosis; it must be correlated with clinical and radiological findings. I strongly advise against stopping any prescribed medication without prior consultation. As a medical geneticist, I recommend discussing results with a clinical geneticist to fully interpret variant pathogenicity and to plan appropriate surveillance.”
Advisory: Medication Caution
Do not discontinue or adjust any prescribed medication based solely on this test result without consulting your treating physician. This genetic test does not provide guidance on medication management.
Exclusion Criteria & Red Flags
- Active febrile illness requiring hospitalization; defer elective phlebotomy.
- Severe thrombocytopenia (platelets <50×10⁹/L) or bleeding disorder – contact the lab for alternative collection.
- Emergency signs: sudden limb pain, blue/ pale extremity, or compartment syndrome – seek immediate ER care; do not wait for genetic results.
Patient FAQ & Clinical Guidance
1. When is WNT7A gene testing recommended in newborns and children?
WNT7A sequencing is recommended for any neonate or child presenting with fibular hypoplasia/aplasia, femoral bowing, or extra digits, especially when a family history suggests an autosomal dominant or recessive pattern with limb anomalies.
2. Can this test be performed using a buccal swab instead of blood?
The test requires blood or extracted DNA; a buccal swab is not accepted. However, a single drop of blood on an FTA card is an accepted alternative for infants with difficult venous access.
3. How long does it take to receive results, and how are they delivered?
Results are typically completed in 3–4 weeks and delivered via a secure, encrypted PDF report. A DHA-licensed genetic counsellor will call to explain the clinical meaning and next steps.
