Understanding Your Results

Results indicate the presence or absence of pathogenic mutations in the CD79A gene. Positive results confirm diagnosis, while negative results may require further clinical evaluation.
📊

Pathogenic variant detected

Confirms diagnosis of CD79A Gene Agammaglobulinemia Type 3. Recommend immunologist consultation for management.

📊

No pathogenic variant detected

Unlikely to have CD79A-related agammaglobulinemia. Consider other genetic or immunological tests if symptoms persist.

📊

Variant of uncertain significance (VUS)

Further testing and clinical correlation recommended. Genetic counseling advised.

⚠️ When to Consult a Doctor:

Consult a doctor if you or your child experience recurrent infections, chronic diarrhea, poor growth, or have a family history of immunodeficiency. Early diagnosis and treatment can prevent complications.

Limitations

  • This test does not detect mutations in other genes associated with agammaglobulinemia
  • Results may require confirmation with additional testing
  • Genetic variants of uncertain significance (VUS) may be identified

Risks & Considerations

  • Minor bruising or discomfort at the blood draw site
  • Rare risk of infection

Interfering Factors

  • Contaminated or degraded DNA samples
  • Recent blood transfusions may affect results

Frequently Asked Questions

What is CD79A Gene Agammaglobulinemia Type 3?
It is an autosomal recessive genetic disorder caused by mutations in the CD79A gene, leading to impaired B-cell function and antibody deficiency, resulting in recurrent infections.
What are the common symptoms of this condition?
Symptoms include recurrent bacterial and viral infections, chronic diarrhea, failure to thrive, and poor growth, typically appearing in early childhood.
How is the CD79A Gene Test performed?
The test uses Next-Generation Sequencing (NGS) to analyze the CD79A gene from a blood or DNA sample, identifying mutations associated with the disorder.
What is the cost of the CD79A Gene Test at DNA Labs India?
The test costs INR 20,000, 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 receive the test results?
Results are typically available within 3 to 4 weeks after sample collection.
What should I do before taking the test?
Provide a detailed clinical history and undergo a genetic counseling session to assess family history and draw a pedigree chart.
Is the CD79A Gene Test covered by insurance?
Coverage varies by insurance plan. It is recommended to check with your provider for specific details.
Can this test be performed on children?
Yes, the test is suitable for both pediatric and adult patients, especially if symptoms of immunodeficiency are present.
What are the treatment options after a positive diagnosis?
Treatment may include immunoglobulin replacement therapy, antibiotics for infections, and regular monitoring by an immunologist.
How accurate is the NGS genetic test for CD79A mutations?
NGS technology provides high accuracy in detecting genetic variants, but results should be interpreted in conjunction with clinical evaluation.
Who should consider getting this genetic test?
Individuals with recurrent infections, family history of agammaglobulinemia, or suspected primary immunodeficiency should consider this test after consulting a healthcare provider.
