Understanding Your Results

Results from the FGF8 Gene HH6 NGS Genetic Test indicate the presence or absence of pathogenic mutations in the FGF8 gene. Positive results confirm a genetic diagnosis, while negative results may require further testing.
Positive result: Pathogenic variant detected, confirming HH6 diagnosis. Consult a geneticist for management.
Negative result: No pathogenic variants found. Consider other genetic or non-genetic causes.
Variant of uncertain significance: Further testing or family studies may be needed.
Always correlate results with clinical symptoms and family history.
⚠️ When to Consult a Doctor:

Consult a doctor if you experience symptoms of hypogonadism, such as delayed puberty, infertility, or anosmia, especially with a family history of genetic disorders.

Limitations

  • ⚠May not detect all genetic variants or mutations
  • ⚠Results require interpretation by a genetic specialist
  • ⚠Does not rule out other genetic causes of hypogonadism
  • ⚠Limited to FGF8 gene analysis only

Risks & Considerations

  • ●Minor bruising or pain at the blood draw site
  • ●Rare risk of infection
  • ●Psychological impact of genetic results

Interfering Factors

  • ●Sample contamination
  • ●Improper sample handling or storage
  • ●Recent blood transfusions
  • ●Degraded DNA quality

Frequently Asked Questions

What is FGF8 Gene Hypogonadotropic Hypogonadism Type 6?
It is a genetic condition caused by mutations in the FGF8 gene, leading to low sex hormone levels and potentially anosmia.
What are the common symptoms of HH6?
Symptoms include delayed puberty, infertility, anosmia, low libido, and in males, small testicles or erectile dysfunction.
How is HH6 diagnosed?
Diagnosis involves physical exams, blood tests for hormone levels, and genetic testing like the FGF8 NGS test.
What does the NGS Genetic Test involve?
It uses Next-Generation Sequencing to analyze the FGF8 gene from a blood sample for mutations.
Is the test painful?
The test requires a blood draw, which may cause minor discomfort but is generally not painful.
How long does it take to get results?
Results are typically available within 3 to 4 weeks after sample collection.
Is home sample collection available?
Yes, DNA Labs India offers free home collection across many cities in India.
What if the test is positive?
A positive result confirms HH6; consult a geneticist or endocrinologist for treatment and counseling.
Can the test detect all mutations?
The test targets the FGF8 gene but may not detect all possible genetic variants; further testing might be needed.
Is genetic counseling required?
Yes, genetic counseling is recommended before and after testing to understand implications and results.
Is the test covered by insurance?
Coverage varies; check with your insurance provider or government schemes like PMJAY for details.
How do I book the test?
Book online via DNA Labs India's website or contact their customer service for assistance.
