Test Overview & Methodology
This genetic test provides comprehensive analysis of the TBX20 gene, which is causally linked to atrial septal defect type 4 (ASD4), a common congenital heart malformation. Using next-generation sequencing (NGS), the entire coding region and splice-site boundaries of TBX20 are interrogated to identify pathogenic single-nucleotide variants, insertions, and deletions. Results enable precise molecular diagnosis, guide family cascade screening, and inform clinical management decisions in coordination with paediatric cardiology and clinical genetics services.

Physician Insight & Safety Protocols
โGenetic testing for TBX20-related ASD4 offers families critical answers about the origin of a congenital heart defect. However, a positive result must always be contextualised within the full echocardiographic, electrocardiographic, and pedigree analysis. Our mission is to deliver compassionate, evidence-based counselling alongside every test result.โ โ Lina Osama Zaki Quteineh, Consultant Medical Genetics (DHA: 9294403)
Important Advisory โ Medication Continuation
Do not alter or discontinue any prescribed cardiac medication, including anticoagulants or antiarrhythmics, without direct consultation with your treating cardiologist. Genetic testing provides diagnostic information and does not replace acute medical management.
Exclusion Criteria & Emergency Red Flags
- Inability to provide informed consent (minors require legal guardian authorisation per Federal Decree-Law No. 4 of 2016 on Medical Liability).
- Recent blood transfusion or bone marrow transplant within the past 90 days (may compromise DNA integrity).
- Known interfering medications; consult your physician before specimen collection.
- Seek emergency care immediately if you experience sudden chest pain, severe breathlessness, syncope, or palpitations.
Patient FAQ & Clinical Guidance
1. What does the TBX20 gene test detect?
This test identifies pathogenic and likely pathogenic variants in the TBX20 gene that cause atrial septal defect type 4 (ASD4). It analyses the complete coding sequence and intronโexon boundaries using NGS to detect single-nucleotide variants, small insertions, and deletions. Results enable a definitive molecular diagnosis, inform recurrence risk for family members, and guide cardiology surveillance protocols.
2. How is the sample collected?
A certified phlebotomist collects a peripheral whole blood sample (2โ4 mL) via a standard venipuncture. The collection is performed at your home or office through our VIP Mobile Phlebotomy service, which operates daily from 8 AM to 11 PM. All specimens are transported using ISO-certified temperature-controlled cold-chain logistics to ensure genomic DNA stability from your doorstep to our laboratory.
3. Does UAE insurance cover this genetic test?
Many UAE health insurers provide partial or full coverage for diagnostic genetic testing when ordered by a specialist. We assist with pre-authorisation documentation and direct billing verification through WhatsApp at +971 54 548 8731. Contact our insurance liaison team to confirm your specific policy benefits before scheduling the test.
