01

Start with fit

Is this the right test for you?

The best test starts with a clear clinical question. These are common reasons a clinician or family may consider this test.

  • ✓Symptoms suggestive of Glycogen Storage Disease Type 0 (e.g., hypoglycemia, exercise intolerance, muscle cramps).
  • ✓Family history of Glycogen Storage Disease Type 0.
  • ✓Unexplained metabolic issues.
  • ✓Confirmation of suspected GSD0 diagnosis.
  • ✓Genetic counseling for families with GSD0.

In plain language

What this test helps you understand

This test helps identify specific genetic mutations in the GYS2 gene associated with Glycogen Storage Disease Type 0. It aids in confirming a diagnosis, understanding the underlying cause of symptoms, and informing treatment and management strategies. Results can also be valuable for genetic counseling and family planning.
The GYS2 Gene Glycogen Storage Disease Type 0 NGS Genetic DNA Test is a specialized genetic test used to help diagnose Glycogen Storage Disease Type 0 (GSD0). GSD0 is an inherited metabolic disorder affecting how the body stores and uses glycogen, a form of glucose. This test uses advanced Next-Generation Sequencing (NGS) technology to analyze the GYS2 gene. This gene provides instructions for making an enzyme crucial for glycogen production. Identifying mutations in this gene can help confirm a diagnosis and guide management. This test is particularly relevant for individuals experiencing symptoms like low blood sugar (hypoglycemia), difficulty with exercise, or muscle cramps, or those with a family history of glycogen storage diseases.

PrivacyYour sample and report are handled confidentially. Ask the team how your information is stored and shared.
This test analyzes the GYS2 gene specifically. It may not detect mutations in other genes that could cause similar symptoms. A negative result does not completely rule out all metabolic disorders. Interpretation requires clinical correlation.

Questions people ask

Frequently asked questions

GSD0 is a rare inherited metabolic disorder where the body has difficulty storing and using glycogen, a form of glucose. It is caused by mutations in the GYS2 gene.
Individuals with symptoms like low blood sugar, exercise intolerance, or muscle cramps, or those with a family history of GSD0, should discuss testing with their doctor.
The test analyzes a sample of your blood or DNA to look for specific changes (mutations) in the GYS2 gene using Next-Generation Sequencing (NGS).
Confirm with the laboratory before booking.
Results will be interpreted by genetic specialists. A positive result indicates mutations in the GYS2 gene associated with GSD0. Discuss the results with your healthcare provider for proper interpretation and implications.
Yes, genetic counseling is recommended before testing to understand the implications and after receiving results to discuss findings and family planning.
