Understanding Your Results

Test results indicate the presence or absence of mutations in the GBE1 gene. Positive results confirm the diagnosis of GSD type 4, while negative results may require further clinical evaluation or alternative testing.
Positive: Pathogenic variant detected, confirms Glycogen Storage Disease Type 4
Negative: No pathogenic variant found, consider other differential diagnoses
VUS (Variant of Uncertain Significance): Further testing and genetic counseling recommended
⚠️ When to Consult a Doctor:

If you or your child exhibits symptoms such as enlarged liver, poor growth, muscle weakness, or low blood sugar, or if there is a family history of glycogen storage disease.

Limitations

  • May not detect all types of genetic variants, such as deep intronic mutations
  • Requires clinical correlation and genetic counseling for interpretation

Risks & Considerations

  • Minimal risk from blood draw, such as bruising, soreness, or rare infection

Interfering Factors

  • Contaminated or degraded DNA sample
  • Improper sample handling or storage

Frequently Asked Questions

What is Glycogen Storage Disease Type 4?
Glycogen Storage Disease Type 4, or Andersen's disease, is a rare inherited disorder caused by mutations in the GBE1 gene, leading to abnormal glycogen storage and energy metabolism issues.
What causes GSD type 4?
It is caused by mutations in the GBE1 gene, which encodes the glycogen branching enzyme necessary for proper glycogen breakdown and storage.
What are the common symptoms of GSD type 4?
Symptoms include enlarged liver and spleen, poor growth, muscle weakness, difficulty breathing, heart failure, developmental delay, and low blood sugar levels.
How is GSD type 4 diagnosed?
Diagnosis involves physical examination, blood tests for enzyme levels, and genetic testing such as the NGS Genetic Test to identify GBE1 gene mutations.
What does the GBE1 Gene NGS Genetic Test involve?
The test uses next-generation sequencing to analyze DNA samples for mutations in the GBE1 gene, providing detailed genetic information for diagnosis.
How much does the test cost in India?
The cost of the GBE1 Gene NGS Genetic Test at DNA Labs India is INR 20000, with free home sample collection available across India.
Is home sample collection available for this test?
Yes, DNA Labs India offers free home sample collection for online bookings in numerous cities across India.
How long does it take to get the test results?
Results are typically available within 3 to 4 weeks after sample collection.
What do the test results mean?
Positive results confirm a diagnosis of GSD type 4, negative results indicate no pathogenic variants were found, and VUS requires further interpretation by a geneticist.
Can GSD type 4 be treated?
There is no cure, but management includes dietary modifications, supportive care, and monitoring for complications. Early diagnosis through genetic testing aids in planning.
Is genetic testing necessary for family members?
Yes, genetic testing can help identify carriers and at-risk family members, enabling informed decisions and early intervention.
