Understanding Your Results

Results from the FGF3 Gene Deafness NGS Genetic Test indicate the presence or absence of pathogenic mutations in the FGF3 gene. Interpretation should be done by a qualified geneticist or healthcare provider.
Positive: Pathogenic variant detected, confirming diagnosis of FGF3-related disorder. Consult a genetic counselor for management and family planning.
Negative: No pathogenic variants detected. Clinical correlation is necessary, as symptoms may be due to other genetic or environmental factors.
Variant of Uncertain Significance (VUS): A genetic variant was found, but its clinical significance is unknown. Further testing or family studies may be recommended.
⚠️ When to Consult a Doctor:

Consult a doctor if you or your child exhibit symptoms such as congenital hearing loss, ear abnormalities, or small teeth, especially with a family history of similar conditions.

Limitations

  • ⚠May not detect all types of mutations, such as large deletions or duplications
  • ⚠Variants of uncertain significance (VUS) may be identified, requiring further evaluation
  • ⚠Test results should be correlated with clinical findings

Risks & Considerations

  • ●Minor bruising or discomfort at blood draw site
  • ●Very low risk of infection
  • ●Psychological impact of results, addressed through counseling

Interfering Factors

  • ●Contaminated or degraded DNA sample
  • ●Insufficient sample volume
  • ●Hemolyzed blood sample

Blood, extracted DNA, or one drop of blood on an FTA card are accepted samples.
Is genetic counseling included?
Yes, genetic counseling is included in the test cost to help interpret results and provide guidance.
What does a positive result mean?
A positive result indicates a pathogenic mutation in the FGF3 gene, confirming the diagnosis. Consult a genetic counselor for next steps.
What if the result is negative?
A negative result means no pathogenic variants were detected, but clinical correlation is advised as symptoms may have other causes.
