Understanding Your Results
Pathogenic variant detected
Confirms diagnosis of autosomal recessive deafness type 67. Genetic counseling recommended.
No pathogenic variant detected
LHFPL5 gene mutations not found. Consider other genetic or environmental causes.
Variant of uncertain significance (VUS)
Further testing and family studies may be needed for clarification.
Consult a doctor or genetic counselor immediately upon receiving positive results or if symptoms persist despite negative results. Seek guidance for management and family planning.
Limitations
- ⚠May not detect all types of mutations, such as large deletions or duplications
- ⚠Results may include variants of uncertain significance (VUS)
- ⚠Does not rule out other genetic or non-genetic causes of deafness
Risks & Considerations
- ●Minimal risk from blood draw, such as bruising or infection
- ●No significant risks associated with genetic testing itself
Interfering Factors
- ●Poor sample quality
- ●Contamination during collection
- ●Insufficient DNA quantity
