Brown Vialetto-Van Laere syndrome gene panel Price
Brief Details
What is the Brown Vialetto-Van Laere Syndrome Gene Panel?
The Brown Vialetto-Van Laere Syndrome Gene Panel is a genetic blood test used to diagnose Brown Vialetto-Van Laere syndrome, a rare inherited neurological condition that affects motor neurons and cranial nerves.
This disorder is most commonly caused by mutations in riboflavin transporter genes, leading to progressive muscle weakness, hearing loss, and breathing difficulties. The test uses next generation sequencing technology to identify disease causing genetic changes, helping confirm diagnosis and guide targeted treatment such as riboflavin supplementation. The test requires a blood sample collected in an EDTA tube.
What Does the Brown Vialetto-Van Laere Syndrome Gene Panel Measure?
This genetic test looks for disease causing changes linked to Brown Vialetto-Van Laere syndrome:
- Detects pathogenic variants associated with riboflavin transporter deficiency
- Helps confirm the diagnosis of Brown Vialetto-Van Laere syndrome
- Supports early diagnosis in individuals with progressive neuromuscular symptoms
- Aids genetic counselling and carrier screening
- Assists clinicians in planning targeted therapy and long term management

| Gene Group | What a Pathogenic Variant May Indicate |
|---|---|
| SLC52A2, SLC52A3 | Riboflavin transporter deficiency causing Brown Vialetto-Van Laere syndrome |
How Should You Prepare for a Brown Vialetto-Van Laere Syndrome Gene Panel?
This genetic test requires minimal preparation from your side:
- No fasting required: You can eat and drink normally before sample collection
- Normal hydration: Maintain your usual fluid intake
- Medication disclosure: Inform your doctor about any medicines or supplements
- Share clinical history: Provide relevant neurological symptoms and family history
- Consent and documentation: Ensure the test requisition form and clinical details are completed
How Is a Brown Vialetto-Van Laere Syndrome Gene Panel Done? (Step-by-Step Procedure)
The test is performed using a standard blood collection process:
- Preparation: A tourniquet is tied around your arm to make veins more visible
- Cleaning: The puncture site is cleaned with antiseptic
- Sample Collection: A sterile needle is used to draw about 3 to 5 ml of blood into an EDTA vacutainer
- Completion: The needle is removed, and a bandage is applied
- Processing: The sample undergoes next generation sequencing to analyse genes linked to the condition
