Nonketotic Hyperglycinemia / Glycine Encephalopathy Panel Price
Brief Details
What is the Nonketotic Hyperglycinemia / Glycine Encephalopathy Panel?
The Nonketotic Hyperglycinemia or Glycine Encephalopathy Panel is a genetic blood test used to identify inherited conditions that cause excessive levels of glycine in the brain. Glycine encephalopathy is a rare metabolic disorder that primarily affects the central nervous system and often presents in early infancy or childhood.
This test analyses key genes involved in glycine breakdown using Next Generation Sequencing technology. It requires an EDTA blood sample and helps doctors confirm a genetic diagnosis, guide treatment planning, and assess risk for other family members.
What Does the Nonketotic Hyperglycinemia / Glycine Encephalopathy Panel Measure?
This genetic test evaluates gene changes linked to glycine metabolism and neurological function:
- Detection of gene mutations responsible for impaired glycine breakdown
- Confirmation of nonketotic hyperglycinemia as the cause of neurological symptoms
- Differentiation from other metabolic or neurodevelopmental disorders
- Support for seizure management and neurodevelopmental care planning
- Guidance for genetic counselling, family screening, and prenatal evaluation
Nonketotic Hyperglycinemia / Glycine Encephalopathy Panel: Who Needs It and Why It’s Done
What Symptoms May Call for a Nonketotic Hyperglycinemia / Glycine Encephalopathy Panel?
Doctors may recommend this test if you or your child shows symptoms such as:
- Severe or recurrent seizures beginning in infancy
- Poor feeding, vomiting, or breathing difficulties in newborns
- Low muscle tone or poor head control
- Developmental delay or loss of developmental milestones
- Episodes of lethargy, altered consciousness, or coma
Who Should Get a Nonketotic Hyperglycinemia / Glycine Encephalopathy Panel?
- Newborns or infants with unexplained seizures or encephalopathy
- Children with developmental delay and suspected metabolic disorders
- Individuals with biochemical findings suggestive of elevated glycine
- Patients with a family history of glycine encephalopathy
- Couples planning a pregnancy with known genetic risk
Why is a Nonketotic Hyperglycinemia / Glycine Encephalopathy Panel Done?
The test helps identify the genetic cause of glycine encephalopathy, enabling early diagnosis, appropriate management, and informed family planning decisions.
Importance of the Nonketotic Hyperglycinemia / Glycine Encephalopathy Panel
Early diagnosis of glycine encephalopathy is critical, as delayed treatment can lead to severe neurological damage. This gene panel allows precise identification of the underlying genetic defect, helping your doctor plan seizure control strategies, supportive therapies, and long term care. It also provides valuable information for prognosis and reduces uncertainty for affected families.

How Should You Prepare for a Nonketotic Hyperglycinemia / Glycine Encephalopathy Panel?
This genetic test requires minimal preparation. Please follow these simple steps:
- 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 for accurate interpretation
- Consent and forms: Ensure the test requisition form and genetic history details are completed
How Is a Nonketotic Hyperglycinemia / Glycine Encephalopathy 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 glycine encephalopathy.
Conditions That May Affect Nonketotic Hyperglycinemia / Glycine Encephalopathy 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
