Congenital Disorders of Glycosylation (CDG) Gene Panel
Test Overview
The Congenital Disorders of Glycosylation (CDG) Gene Panel is an advanced genetic test designed to identify inherited disorders affecting the body’s glycosylation process — the essential biochemical pathway responsible for attaching sugar molecules to proteins and lipids. Defects in this process can impact multiple organs and body systems.
This panel analyzes multiple genes associated with various types of CDG to help diagnose rare metabolic and genetic conditions.
Why This Test Is Recommended
This test may be advised for individuals showing symptoms such as:
- Developmental delay
- Hypotonia (low muscle tone)
- Seizures
- Poor growth or failure to thrive
- Liver dysfunction
- Coagulation abnormalities
- Intellectual disability
- Neurological symptoms
- Muscle weakness
- Eye abnormalities
- Unexplained multisystem disorders
Key Benefits
- Comprehensive screening of CDG-related genes
- Early and accurate diagnosis of rare inherited disorders
- Helps guide treatment and clinical management
- Supports genetic counseling and family planning
- Identifies carrier status in some cases
- Reduces the need for multiple individual genetic tests
What the Test Detects
The panel evaluates mutations and pathogenic variants in genes associated with:
- Protein glycosylation defects
- Lipid glycosylation disorders
- N-linked and O-linked glycosylation abnormalities
- Metabolic pathway dysfunctions linked to CDG syndromes
Commonly analyzed genes may include:
- PMM2
- MPI
- ALG6
- DPAGT1
- SRD5A3
- ATP6V0A2
- And several other clinically relevant CDG-associated genes
Sample Required
- Blood sample (Peripheral Blood)
Methodology
- Next Generation Sequencing (NGS)
- Bioinformatics analysis
- Variant interpretation based on international genetic guidelines
Turnaround Time
Typically 3–6 weeks, depending on laboratory workflow and variant confirmation requirements.
Who Should Consider This Test
- Children with unexplained developmental disorders
- Individuals with suspected metabolic syndromes
- Patients with multisystem involvement
- Families with a history of inherited genetic disorders
- Individuals advised by neurologists, geneticists, or metabolic specialists
Preparation
No special preparation or fasting is usually required.
Important Notes
- Genetic counseling is recommended before and after testing.
- A positive result confirms the presence of a genetic variant associated with CDG.
- A negative result does not completely exclude all genetic conditions.
- Additional family testing may sometimes be advised.
Safety Information
This is a non-invasive diagnostic genetic test performed on a blood sample and carries minimal risk associated with standard blood collection procedures.
Frequently Asked Questions
Is this test suitable for newborns?
Yes, the test can be performed in newborns, children, and adults when clinically indicated.
Can this test confirm all CDG disorders?
The panel covers a broad range of known CDG-related genes, but extremely rare or newly discovered variants may not always be detected.
Do I need a doctor’s prescription?
Usually recommended by a geneticist, pediatrician, neurologist, or metabolic specialist.
