Test Overview & Methodology
The Fragile X Tremor/Ataxia Syndrome (FXTAS) Genetic Test quantifies CGG trinucleotide repeat expansions in the FMR1 gene using PCR‑based fragment analysis and fluorescent STR typing. This provides a definitive molecular diagnosis for adults with late‑onset cerebellar ataxia and intention tremor, while also identifying premutation carrier status (55–200 repeats) essential for genetic counselling and family risk assessment.
| Feature | Our FXTAS PCR/STR Test | Traditional Southern Blot |
|---|---|---|
| Methodology | PCR with capillary electrophoresis fragment analysis and STR sizing | Southern blot hybridization |
| Turnaround Time | 4 working days (sample by Mon 11 AM → report Fri) | 10–14 working days |
| Sensitivity for Premutation Alleles | High – accurately sizes 55–200 repeats | Moderate; often requires additional PCR confirmation |
| Sample Volume | 4 mL whole blood in EDTA (Lavender Top), refrigerated | 7–10 mL; higher volume needed |
| Price (UAE) | 1300 AED | 1900–2500 AED (estimated) |
Physician Insight & Safety Protocols
“As a Consultant Medical Genetics, I recognize the anxiety that unexplained tremor and imbalance bring. This test offers objective clarity, distinguishing FXTAS from mimics like essential tremor or multiple‑system atrophy, and opens the door to targeted multidisciplinary care. A detailed neurological examination remains essential; results must always be interpreted within the full clinical context.”

⚠ Medication Advisory
Do not discontinue any prescribed neurological medication without consulting your doctor. Abrupt changes can worsen ataxia or tremor symptoms. Always provide a full current medication list to the laboratory and your consulting physician.
Patient Safety & Exclusion Criteria
- Not indicated for routine screening of asymptomatic individuals without clinical suspicion of FXTAS.
- Do not use for diagnosis of classic Fragile X syndrome in children (FMR1 full mutation testing required).
- Sample must be kept refrigerated; DO NOT FREEZE. Frozen specimens cannot be processed.
- Duly filled Genomics Clinical Information Requisition Form (Form 20) is mandatory.
- Emergency red flags: Sudden severe ataxia with loss of consciousness, new‑onset seizures, or acute stroke symptoms → call 998 immediately.
Patient FAQ & Clinical Guidance
1. What does the FXTAS test detect, and who should consider it?
It detects CGG repeat expansions in the FMR1 gene causing Late‑Onset Ataxia and Tremor Syndrome. Adults over 50 with progressive cerebellar ataxia, intention tremor, and a family history of Fragile X‑associated disorders should discuss testing with a neurologist or genetic counsellor.
2. How is the sample collected and what is the accuracy?
The test uses 4 mL whole blood in an EDTA tube, collected at home by our VIP mobile phlebotomist under strict cold‑chain conditions. Diagnostic accuracy exceeds 99.9% for detecting premutation expansions (55–200 repeats).
3. Is the blood draw painful, and what support do you provide after results?
The venipuncture is quick and minimally invasive, with our VIP phlebotomy team ensuring maximum comfort. After the report, a DHA‑licensed Consultant Medical Genetics offers a telephonic consultation to explain your results and guide next steps.
