Glycosylation Disorder Gene (CDG) Panel
Glycosylation Disorder Gene (CDG) Panel Price
Brief Details
What is the Glycosylation Disorder Gene (CDG) Panel?
The Glycosylation Disorder Gene Panel is a genetic blood test used to identify inherited conditions known as congenital disorders of glycosylation. These disorders affect how sugars are attached to proteins and fats, a process that is essential for normal growth, brain development, and organ function.
This test analyses a wide range of genes involved in glycosylation using Next Generation Sequencing technology. It requires an EDTA blood sample and helps doctors confirm a diagnosis, understand disease severity, and guide long term care and family planning.
What Does the Glycosylation Disorder Gene (CDG) Panel Measure?
This genetic test looks for changes in genes responsible for protein and lipid glycosylation to support accurate diagnosis and care planning:
- Detection of disease causing variants linked to congenital disorders of glycosylation
- Differentiation of CDG from other genetic or metabolic syndromes
- Identification of inherited risk affecting multiple body systems
- Support for neurological, developmental, and systemic management strategies
- Guidance for genetic counselling, family screening, and prenatal evaluation
Glycosylation Disorder Gene (CDG) Panel: Who Needs It and Why It’s Done
What Symptoms May Call for a Glycosylation Disorder Gene (CDG) Panel?
Doctors may recommend this test if you or your child experience a combination of unexplained symptoms such as:
- Developmental delay or intellectual disability
- Low muscle tone or poor coordination
- Seizures or movement disorders
- Failure to thrive or feeding difficulties
- Liver dysfunction or abnormal blood clotting
- Multisystem involvement affecting the brain, heart, eyes, or skeleton
Who Should Get a Glycosylation Disorder Gene (CDG) Panel?
- Infants or children with unexplained developmental or neurological symptoms
- Individuals with suspected inherited metabolic or genetic syndromes
- Patients showing multisystem involvement without a clear diagnosis
- Individuals with a family history of congenital disorders of glycosylation
- Couples planning a pregnancy with known genetic risk
Why is a Glycosylation Disorder Gene (CDG) Panel Done?
The test helps identify the genetic cause of congenital disorders of glycosylation, allowing early diagnosis, targeted management, and informed family planning decisions.
Importance of the Glycosylation Disorder Gene (CDG) Panel
Congenital disorders of glycosylation can affect multiple organs and may worsen over time if not identified early. This gene panel enables precise diagnosis by identifying the underlying genetic defect, helping your doctor plan appropriate supportive care, anticipate complications, and provide clearer information about prognosis. Early detection also helps families access timely interventions and specialist support.

Interpreting Glycosylation Disorder Gene (CDG) Panel Results
What Your Glycosylation Disorder Gene (CDG) Panel Results May Indicate
| Parameter | Expected Finding | Pathogenic Variant Detected May Indicate | No Variant Detected May Indicate |
|---|---|---|---|
| CDG related genes | No disease causing variant detected | Congenital disorder of glycosylation affecting protein and lipid processing | Symptoms may be due to other genetic or metabolic conditions |
Understanding Abnormal Glycosylation Disorder Gene (CDG) Panel Test Results
| Gene Group | What a Pathogenic Variant May Indicate |
|---|---|
| ALG, DPAGT, DPM genes | Defects in early glycosylation steps affecting protein processing |
| COG and TMEM genes | Impaired intracellular protein trafficking and glycosylation |
| PIG and PGAP genes | GPI anchor synthesis disorders with neurological involvement |
| PMM2 and related genes | Common CDG subtypes affecting multiple organ systems |
| EXT, B4GALT, CHST genes | Disorders impacting connective tissue and skeletal development |
How Should You Prepare for a Glycosylation Disorder Gene (CDG) Panel?
This genetic test requires minimal preparation. Please keep the following points in mind:
- No fasting required: You can eat and drink normally unless advised otherwise by your doctor
- Normal hydration: Continue your usual fluid intake
- Medication information: Inform your doctor about all medicines or supplements you are taking
- Clinical history: Share relevant medical and family history to support accurate interpretation
- Consent and forms: Ensure the test requisition form and genetic history details are completed
How Is a Glycosylation Disorder Gene (CDG) Panel Done? (Step-by-Step Procedure)
The test is performed using a simple 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 is analysed using Next Generation Sequencing to identify gene mutations linked to glycosylation disorders.
Conditions That May Affect Glycosylation Disorder Gene (CDG) Panel Accuracy
Certain patient related factors may influence test interpretation:
- Recent blood transfusion may affect genetic analysis
- Incomplete or incorrect clinical history can limit interpretation
- Mosaic genetic changes may be harder to detect in some individuals
- Variants of uncertain significance may require further family testing
