Test Overview & Methodology
The B3GAT3 next‑generation sequencing test screens for pathogenic variants in the B3GAT3 gene, implicated in linkeropathy type 2. This disorder is characterised by multiple joint dislocations, short stature, craniofacial dysmorphism, and congenital heart defects. Molecular confirmation supports clinical diagnosis and family risk assessment. Intended ordering specialists: clinical geneticists, paediatricians, and cardiologists.

| Expert Consultation | Telephonic genetic counselling included | None |
Physician Insight & Safety Protocols
“As a consultant medical geneticist, I stress that a genetic test result must be interpreted within the full clinical context — including phenotyping, family history, and multidisciplinary evaluation. A positive finding guides management, but it is not a standalone diagnosis. Always discuss any medication adjustments with your treating physician before making changes.”
— Lina Osama Zaki Quteineh, Consultant Medical Genetics, DHA Registration ID: 9294403
Important Advisory
Do not alter or discontinue any prescribed medication, including cardiac or joint symptom therapies, without prior consultation with your doctor. Abrupt changes may worsen clinical status.
Exclusion Criteria & Emergency Red Flags
- Home collection is not suitable for patients currently in acute psychiatric crisis or lacking a responsible adult companion.
- Individuals diagnosed with frailty syndrome requiring constant supervision must be accompanied by a caregiver during sample collection.
- If the patient develops sudden chest pain, palpitations, or shortness of breath within 24 hours prior to collection, postpone and seek urgent medical care.
- For minors: a legal guardian must provide written informed consent in accordance with Federal Decree‑Law No. 4 of 2016 on Medical Liability.
- Do not attempt to draw blood if the patient is on high‑dose anticoagulants without physician clearance.
Patient FAQ & Clinical Guidance
1. How accurate is the B3GAT3 NGS test for detecting the disorder?
With 99.9% sensitivity for single‑nucleotide variants and exon‑level copy number changes, this test is the gold standard for molecular confirmation of linkeropathy type 2, delivering actionable results within 3–4 weeks.
2. Do I need to fast or prepare in any special way before the test?
No special preparation — including fasting — is required. However, a pre‑test genetic counselling session is recommended to accurately document the family history.
3. How long does it take to get the results, and does the report include genetic counselling?
Results are issued within 3–4 weeks. The final report includes a detailed variant interpretation, ACMG classification, and a telephonic genetic counselling session with a consultant medical geneticist.
4. What sample types are accepted for this test?
We accept whole blood (3 mL EDTA), buccal swab, or a single drop of blood on an FTA card. This flexibility enables non‑invasive collection even for infants and patients with difficult venous access.
5. Does health insurance cover genetic testing in the UAE?
We provide direct billing verification via WhatsApp before the test. Many insurance companies cover the test when ordered with clear clinical indications. Contact us at +971 54 548 8731 for a pre‑authorisation check.
