Neurofibromatosis type 1 (NF1) gene analysis Price
Brief Details
What is the Neurofibromatosis Type 1 (NF1) Gene Analysis Test?
The Neurofibromatosis Type 1 (NF1) Gene Analysis Test is a genetic blood test used to diagnose Neurofibromatosis Type 1, a common inherited condition that affects the skin, nerves, and other body systems. It is characterised by the development of café au lait spots, neurofibromas, and a wide range of neurological and skeletal manifestations.
This test analyses the NF1 gene using next generation sequencing technology to identify disease causing genetic changes. Confirming a pathogenic variant helps establish the diagnosis, understand disease variability, and guide long-term monitoring and care. The test requires a blood sample collected in an EDTA tube.
What Does the Neurofibromatosis Type 1 (NF1) Gene Analysis Test Measure?
This genetic test looks for disease causing changes in the NF1 gene:
- Detects pathogenic variants responsible for Neurofibromatosis Type 1
- Helps confirm inherited tumour predisposition syndromes
- Supports diagnosis in individuals with characteristic skin or nerve findings
- Aids genetic counselling and family screening
- Guides monitoring of tumour related complications

- Multiple café au lait spots on the skin
- Cutaneous or plexiform neurofibromas
- Freckling in the armpits or groin area
- Learning difficulties or developmental delay
- Bone abnormalities or unexplained scoliosis
Who Should Get a Neurofibromatosis Type 1 (NF1) Gene Analysis Test?

Interpreting Neurofibromatosis Type 1 (NF1) Gene Analysis Test Results
What Your Neurofibromatosis Type 1 (NF1) Gene Analysis Results May Indicate
| Parameter | Expected Finding | Pathogenic Variant Detected May Indicate | No Variant Detected May Indicate |
|---|---|---|---|
| NF1 gene | No disease causing variant detected | Confirmed genetic Neurofibromatosis Type 1 | Symptoms may be due to other conditions or variants not detected by this analysis |
Understanding Abnormal Neurofibromatosis Type 1 (NF1) Gene Analysis Results
| Finding | What It May Indicate |
|---|---|
| Pathogenic NF1 variant | Neurofibromatosis Type 1 with tumour predisposition |
| No pathogenic variant | Alternative genetic or non genetic causes may need evaluation |
How Should You Prepare for a Neurofibromatosis Type 1 (NF1) Gene Analysis Test?
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 you are taking
- Share clinical history: Provide relevant medical and family history as advised
- Consent and documentation: Ensure the test requisition form and genetic history details are completed
How Is a Neurofibromatosis Type 1 (NF1) Gene Analysis Test 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 the NF1 gene
Conditions That May Affect Neurofibromatosis Type 1 (NF1) Gene Analysis Test Accuracy
Certain patient related factors may influence test interpretation:
- Recent blood transfusion, which may affect genetic analysis
- Incomplete or inaccurate family history details
- Presence of mosaic genetic changes requiring clinical correlation
