Test Overview & Methodology
The FISH microdeletion test for Williams syndrome detects the deletion of the elastin gene (ELN) on chromosome 7q11.23, confirming the diagnosis of this multisystem genetic disorder. This test is essential for paediatric and neonatal patients presenting with characteristic cardiovascular (supravalvular aortic stenosis) and developmental features. Fluorescence In Situ Hybridization offers targeted, high-resolution detection of submicroscopic deletions with greater than 99% sensitivity, enabling definitive molecular diagnosis and informed clinical management.
| Feature | Our FISH Test (Williams Syndrome) | Chromosomal Microarray (CMA) |
|---|---|---|
| Precision / Method | Targeted Fluorescence In Situ Hybridization for 7q11.23; 99.9% sensitivity | Genome‑wide copy number analysis; may miss small deletions or require confirmation by FISH |
| Turnaround Time | 4 working days | 7–14 working days |
| Cost (AED) | 1200 | 2500–4000 |
Physician Insight & Safety Protocols
“Williams syndrome diagnosis requires correlation of FISH results with clinical evaluation, including cardiac, endocrine, and behavioural assessments. A negative FISH result does not exclude clinical suspicion if symptoms strongly align; further genetic testing may be warranted. We ensure compassionate communication of results and a clear management plan.”

Advisory Note on Medications
Do not discontinue prescribed medication without consulting your doctor. This is critical for patients on beta‑blockers, vasodilators, or hormonal therapies commonly used in Williams syndrome management.
Exclusion Criteria & Emergency Red Flags
- Exclusion: Patients under 1 month of age; severely haemolysed, clotted, or insufficient blood samples will be rejected.
- ER Red Flags: Sudden chest pain, syncope, severe hypertension crisis, or signs of acute heart failure—proceed directly to the nearest emergency department. Do not delay for sample collection.
