Neurofibromatosis type 2 (NF2) Gene Panel by NGS, EDTA Blood**

What is the Neurofibromatosis Type 2 (NF2) Gene Analysis Test?

The Neurofibromatosis Type 2 (NF2) Gene Analysis Test is a genetic blood test used to diagnose Neurofibromatosis Type 2, a rare inherited condition characterised by the development of non cancerous tumours of the nervous system, most commonly affecting the hearing and balance nerves.

This test analyses the NF2 gene using next generation sequencing technology to identify disease causing genetic changes. Confirming a pathogenic variant helps establish the diagnosis, assess disease risk, and guide long-term clinical management. The test requires a blood sample collected in an EDTA tube.

What Does the Neurofibromatosis Type 2 (NF2) Gene Analysis Test Measure?

This genetic test looks for disease causing changes in the NF2 gene:

• Detects pathogenic variants responsible for Neurofibromatosis Type 2
• Helps confirm inherited tumour predisposition syndromes
• Supports diagnosis in individuals with bilateral vestibular schwannomas
• Aids genetic counselling and family risk assessment
• Guides surgical planning and long-term tumour surveillance

Neurofibromatosis Type 2 (NF2) Gene Analysis Test: Who Needs It and Why It’s Done

What Symptoms May Call for a Neurofibromatosis Type 2 (NF2) Gene Analysis Test?

Doctors may recommend this test if you or a family member experience:

• Hearing loss or ringing in the ears at a young age
• Balance problems or dizziness
• Facial weakness or numbness
• Recurrent headaches or vision changes
• Multiple nervous system tumours detected on imaging

Who Should Get a Neurofibromatosis Type 2 (NF2) Gene Analysis Test?

This test may be advised for:

• Individuals with clinical features suggestive of Neurofibromatosis Type 2
• Patients with bilateral vestibular schwannomas
• Individuals with multiple meningiomas or spinal tumours
• People with a family history of Neurofibromatosis Type 2
• Families seeking genetic counselling and screening

Why is the Neurofibromatosis Type 2 (NF2) Gene Analysis Test Done?

The test helps confirm the genetic cause of Neurofibromatosis Type 2, allowing accurate diagnosis, informed treatment decisions, and appropriate family counselling.

How Is a Neurofibromatosis Type 2 (NF2) 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 NF2 gene

Conditions That May Affect Neurofibromatosis Type 2 (NF2) 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

Diseases That the Neurofibromatosis Type 2 (NF2) Gene Analysis Test Can Help Detect

• Neurofibromatosis Type 2
