Understanding Your Results

Results indicate the presence or absence of pathogenic mutations in the KCNA5 gene. Positive results may confirm a genetic predisposition to atrial fibrillation type 7, while negative results do not entirely exclude genetic factors.
📊

Pathogenic mutation detected

Confirms genetic cause of atrial fibrillation type 7; consider family screening and personalized treatment.

📊

Variant of uncertain significance (VUS)

Further testing or clinical correlation needed; genetic counseling recommended.

📊

No pathogenic mutation detected

Genetic cause not identified with this test; other factors may be involved.

⚠️ When to Consult a Doctor:

Consult a cardiologist or geneticist if you experience symptoms of atrial fibrillation, have a family history, or receive a positive genetic test result for management and family planning.

Limitations

  • ⚠May not detect all genetic variants or mutations in KCNA5
  • ⚠Results require correlation with clinical findings and family history
  • ⚠Does not rule out other causes of atrial fibrillation

Risks & Considerations

  • ●Minimal risk from blood draw, such as bruising or infection
  • ●Psychological impact from genetic results, addressed through counseling

Interfering Factors

  • ●Poor sample quality
  • ●Contamination during sample collection or processing

Frequently Asked Questions

What is the KCNA5 Gene Atrial Fibrillation Type 7 NGS Genetic Test?
It is a genetic test that uses Next-Generation Sequencing to identify mutations in the KCNA5 gene, which are associated with hereditary atrial fibrillation type 7.
Who should consider this test?
Individuals with a family history of atrial fibrillation, symptoms like palpitations, or diagnosed atrial fibrillation, especially if genetic causes are suspected.
How is the test performed?
A blood sample or DNA extract is analyzed using NGS technology to detect mutations in the KCNA5 gene.
What is the cost of the test?
The test costs INR 20,000, which includes the genetic test, result interpretation, and genetic counseling.
Is home sample collection available?
Yes, DNA Labs India offers free home sample collection for online bookings across India.
How long does it take to get results?
Results are typically available within 3 to 4 weeks after sample collection.
What do the results mean?
Results indicate if pathogenic mutations in KCNA5 are present, helping diagnose genetic atrial fibrillation and guide treatment.
Are there any risks associated with the test?
The test involves minimal risks from blood draw, such as bruising. Genetic counseling is provided to address any psychological concerns.
Is the test covered by insurance?
Coverage varies; it is not typically covered under government schemes like PMJAY, but check with private insurers.
Can this test diagnose atrial fibrillation?
It helps identify a genetic cause for atrial fibrillation type 7, but diagnosis also requires clinical evaluation and other tests.
What is the role of the KCNA5 gene in atrial fibrillation?
KCNA5 encodes a potassium channel protein involved in heart electrical activity; mutations can disrupt rhythm and lead to atrial fibrillation.
How can I prepare for the test?
No special preparation is needed, but attend a genetic counseling session to provide clinical history and understand the test process.
