PMP22 Gene Analysis (Inflammatory Demyelinating Polyneuropathy Screen)
PMP22 gene analysis (inflammatory demyelinating polyneuropathy screen) Price
Brief Details
What is the PMP22 Gene Analysis (Inflammatory Demyelinating Polyneuropathy Screen)?
The PMP22 gene analysis is a specialised genetic blood test that looks for changes in the PMP22 gene, which plays an important role in the formation and maintenance of peripheral nerves. These nerves carry signals between your brain, spinal cord, and the rest of your body, helping control movement and sensation.
This test uses a blood sample to analyse the PMP22 gene through advanced Next Generation Sequencing technology. Doctors commonly recommend it to identify inherited causes of demyelinating peripheral neuropathy, a condition where the protective covering of nerves is damaged, leading to weakness, numbness, balance issues, or coordination problems.
What Does the PMP22 Gene Analysis Measure?
This genetic test provides detailed insights into nerve health by analysing the PMP22 gene:
- Detection of disease causing mutations or copy number changes affecting peripheral nerve myelin
- Identification of inherited neuropathies linked to PMP22 gene abnormalities
- Differentiation between genetic neuropathies and acquired or inflammatory nerve conditions
- Support for diagnosis when symptoms, nerve conduction studies, or imaging are inconclusive
PMP22 Gene Analysis: Who Needs It and Why It’s Done
What Symptoms May Call for a PMP22 Gene Analysis?
Your doctor may advise this test if you have symptoms suggesting peripheral nerve involvement, such as:
- Gradually worsening muscle weakness, especially in the hands or feet
- Numbness, tingling, or reduced sensation in the arms or legs
- Frequent ankle sprains, foot drop, or difficulty walking
- High foot arches, hammer toes, or other foot deformities
- Recurrent nerve palsies triggered by mild pressure or minor injuries
Who Should Get a PMP22 Gene Analysis?
This test is recommended for:
- Individuals with unexplained or longstanding peripheral neuropathy
- People with a family history of inherited nerve disorders
- Patients suspected of having Charcot Marie Tooth disease or related conditions
- Individuals with recurrent pressure related nerve palsies
- Families seeking genetic counselling or carrier screening
Why is the PMP22 Gene Analysis (Inflammatory Demyelinating Polyneuropathy Screen) Done?
The test helps confirm or rule out inherited demyelinating neuropathies by identifying genetic changes in the PMP22 gene, allowing for accurate diagnosis, appropriate management, and long term care planning.
Importance of PMP22 Gene Analysis (Inflammatory Demyelinating Polyneuropathy Screen)
PMP22 gene analysis plays a crucial role in understanding the root cause of inherited nerve disorders. A confirmed genetic diagnosis helps avoid unnecessary treatments, supports tailored physiotherapy and rehabilitation plans, and enables doctors to distinguish genetic neuropathies from inflammatory or acquired nerve conditions. The results also provide valuable information for family planning, carrier detection, and genetic counselling.

Interpreting PMP22 Gene Analysis Results
What Your PMP22 Gene Analysis Results May Indicate
| Parameter | Expected Finding | Pathogenic Variant Detected May Indicate | No Variant Detected May Indicate |
|---|---|---|---|
| PMP22 gene | No disease causing variant detected | Inherited demyelinating neuropathy such as Charcot Marie Tooth disease type 1A or hereditary neuropathy with liability to pressure palsies | Symptoms may be due to inflammatory neuropathy, other genetic causes, or variants not detected by this test |
Understanding Abnormal PMP22 Gene Analysis Test Results
| Gene | What a Pathogenic Variant May Indicate |
|---|---|
| PMP22 | Charcot Marie Tooth disease type 1A or hereditary neuropathy with liability to pressure palsies |
How Should You Prepare for a PMP22 Gene Analysis?
This genetic test requires minimal preparation from your side:
- No fasting required: You can eat and drink normally before sample collection
- Medication information: Inform your doctor about all medicines or supplements you are taking
- Clinical history: Share details of nerve related symptoms or family history of neuropathy
- Test requisition form: Ensure the completed test requisition form and clinical information are provided
How Is a PMP22 Gene Analysis (Inflammatory Demyelinating Polyneuropathy Screen) Done? (Step-by-Step Procedure)
The test is carried out 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 collect about 3 to 5 ml of blood into an EDTA vacutainer
- Completion: The needle is removed, and a bandage is applied
- Processing: The blood sample is analysed using Next Generation Sequencing to study the PMP22 gene
Conditions That May Affect PMP22 Gene Analysis Accuracy
Certain patient related factors may influence result interpretation:
- Incomplete clinical history may limit correlation with genetic findings
- Variants of uncertain significance may require clinical follow up and repeat evaluation
- Family history details are important for accurate interpretation of genetic changes
Diseases That PMP22 Gene Analysis Can Help Detect
- Charcot Marie Tooth disease type 1A
- Hereditary neuropathy with liability to pressure palsies
- Inherited demyelinating peripheral neuropathies
- Genetic causes of chronic peripheral nerve weakness
