Understanding Your Results
Pathogenic variant detected
Confirms diagnosis of CPVT type 4; recommend clinical management and family screening
No pathogenic variant detected
Reduces likelihood of CALM1-related CPVT; consider other genetic or non-genetic causes
Variant of uncertain significance (VUS)
Requires further evaluation and genetic counseling; may not be causative
Consult a cardiologist or geneticist if you experience symptoms like fainting, palpitations, or have a family history of CPVT. After receiving test results, seek professional guidance for management and family screening.
Limitations
- ⚠May not detect all genetic variants due to technical limitations
- ⚠Variants of uncertain significance (VUS) may require further evaluation
- ⚠Does not rule out other genetic or non-genetic causes of CPVT
- ⚠Results should be correlated with clinical findings
Risks & Considerations
- ●Minimal risk from blood draw: bruising, infection, or discomfort
- ●Psychological impact of genetic results; counseling recommended
Interfering Factors
- ●Poor sample quality or contamination
- ●Recent blood transfusion
- ●Inadequate sample volume
- ●Technical errors in sequencing
