Krabbe Disease (GALC) Gene Analysis Test
Krabbe disease (GALC) gene analysis Price
Brief Details
What is the Krabbe Disease (GALC) Gene Analysis Test?
The Krabbe Disease (GALC) Gene Analysis Test is a genetic blood test used to diagnose Krabbe disease, a rare inherited disorder that affects the nervous system. The condition leads to progressive damage of the brain and peripheral nerves due to the loss of protective myelin covering nerve cells.
This test analyses the GALC gene using next generation sequencing technology to identify disease causing genetic changes. Confirming a pathogenic variant helps establish the diagnosis, assess disease type, and support clinical decision making. The test requires a blood sample collected in an EDTA tube.
What Does the Krabbe Disease (GALC) Gene Analysis Test Measure?
This genetic test looks for disease causing changes in the GALC gene:
- Detects pathogenic variants responsible for Krabbe disease
- Helps confirm the cause of progressive neurodegeneration
- Supports early diagnosis in infants and children with developmental regression
- Aids genetic counselling and family screening
- Guides prognosis and long-term care planning

- Developmental delay or loss of milestones
- Muscle stiffness or weakness
- Feeding difficulties and irritability in infants
- Seizures or abnormal movements
- Vision or hearing impairment
Who Should Get a Krabbe Disease (GALC) Gene Analysis Test?

Interpreting Krabbe Disease (GALC) Gene Analysis Test Results
What Your Krabbe Disease (GALC) Gene Analysis Results May Indicate
| Parameter | Expected Finding | Pathogenic Variant Detected May Indicate | No Variant Detected May Indicate |
|---|---|---|---|
| GALC gene | No disease causing variant detected | Confirmed genetic Krabbe disease or carrier status | Symptoms may be due to other leukodystrophies or variants not detected by this analysis |
Understanding Abnormal Krabbe Disease (GALC) Gene Analysis Results
| Finding | What It May Indicate |
|---|---|
| Pathogenic GALC variant | Krabbe disease with progressive neurological involvement |
| No pathogenic variant | Alternative neurological or metabolic disorder may need evaluation |
How Should You Prepare for a Krabbe Disease (GALC) 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 Krabbe Disease (GALC) 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 GALC gene
Conditions That May Affect Krabbe Disease (GALC) Gene Analysis Test Accuracy
