Sample Stability
- Hemolyzed or clotted blood sample
- Incorrect labeling or insufficient sample volume
- Contaminated or degraded sample
- Failure to meet pre-test requirements
Understanding Your Results
Positive for pathogenic variant
Mutation detected in TLL1 gene, confirming genetic basis for ASD type 6. Consult genetic counselor for management and family planning.
Negative for pathogenic variant
No mutation found in TLL1 gene. Clinical symptoms may require further diagnostic evaluation.
Variant of uncertain significance
Genetic variant detected but clinical significance unknown. Additional testing or family studies may be needed.
If symptoms of atrial septal defect persist, if there is a family history of congenital heart defects, or after receiving test results, consult a cardiologist or geneticist for personalized advice.
Limitations
- ⚠May not detect all genetic variants or mutations
- ⚠Results require clinical correlation and are not standalone diagnostic
- ⚠Cannot predict disease severity or onset with certainty
- ⚠Limited to TLL1 gene analysis; other genetic factors may be involved
Risks & Considerations
- ●Minimal risk from blood draw, such as bruising or infection
- ●Potential psychological impact of genetic results
- ●Concerns about genetic discrimination or privacy
- ●False positives or negatives requiring further testing
Interfering Factors
- ●Contaminated or degraded DNA sample
- ●Insufficient sample volume or quality
- ●Technical errors during sequencing or analysis
- ●Patient medications or conditions affecting DNA integrity
