Understanding Your Results

Results from the DTNA gene NGS test help determine the genetic basis of left ventricular noncompaction.
Positive result: Pathogenic variant in DTNA gene detected, confirming genetic cause
Negative result: No pathogenic variants found; clinical correlation recommended
Variant of uncertain significance (VUS): Further testing or family studies may be needed
⚠️ When to Consult a Doctor:

If symptoms persist or worsen, or if genetic test results indicate a pathogenic variant, consult a cardiologist or geneticist for management and family screening.

Limitations

  • ⚠May not detect all types of mutations, such as large deletions or duplications
  • ⚠Variants of uncertain significance (VUS) may be identified
  • ⚠Requires genetic counseling for interpretation

Risks & Considerations

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

Interfering Factors

  • ●Hemolyzed or degraded DNA samples
  • ●Improper sample storage or transport
  • ●Contamination during collection

Frequently Asked Questions

What is DTNA Gene LVNC 1?
DTNA Gene LVNC 1 is a genetic form of left ventricular noncompaction caused by mutations in the DTNA gene, leading to abnormal heart muscle development.
What are the symptoms of LVNC?
Symptoms include fatigue, shortness of breath, chest pain, irregular heartbeat, and fainting, though some individuals may be asymptomatic.
How is LVNC diagnosed?
Diagnosis involves echocardiogram, cardiac MRI, ECG, and genetic testing to identify mutations in genes like DTNA.
What is NGS genetic testing?
Next-generation sequencing (NGS) is a technology that analyzes multiple genes simultaneously to detect mutations associated with genetic conditions.
What does the test involve?
The test requires a blood sample or extracted DNA, which is analyzed using NGS to sequence the DTNA gene for mutations.
How long does it take to get results?
Results are typically available within 3 to 4 weeks after sample collection.
What is the cost of the test?
The cost of the DTNA Gene LVNC 1 NGS Genetic Test at DNA Labs India is INR 20,000.
Is home sample collection available?
Yes, free home sample collection is available for online bookings across India.
What should I do before the test?
Provide your clinical history and family pedigree during a genetic counseling session prior to testing.
How accurate is the genetic test?
NGS testing is highly accurate for detecting mutations, but may not identify all types of genetic variations.
What if the test result is positive?
A positive result confirms a genetic cause for LVNC; consult a healthcare provider for management and family screening.
Can this test be used for family screening?
Yes, genetic testing can help identify at-risk family members and guide preventive measures.
