Understanding Your Results
No pathogenic variants detected
Normal; no mutations in HBA2 gene linked to alpha thalassemia
Pathogenic variant detected
Carrier or affected status for alpha thalassemia; clinical correlation and genetic counseling recommended
Variant of uncertain significance
Further testing or family studies may be needed for clarification
Consult a doctor or genetic counselor if you have a family history of thalassemia, experience symptoms like persistent anemia, or receive a positive test result for guidance on management and family planning.
Limitations
- ⚠May not detect all rare or novel mutations in the HBA2 gene
- ⚠Results require interpretation by a genetic counselor or healthcare provider
- ⚠Does not assess mutations in other thalassemia-related genes like HBA1
Risks & Considerations
- ●Minimal risk from blood draw, such as slight pain, bruising, or infection at the puncture site
Interfering Factors
- ●Poor sample quality or insufficient DNA
- ●Contamination during sample collection or processing
- ●Recent blood transfusions may affect DNA analysis
