Understanding Your Results
Pathogenic variant detected
Confirms diagnosis of Hypomagnesemia type 5. Refer to genetic counselor and specialist for management.
No pathogenic variant detected
May not have genetic form of hypomagnesemia. Consider other causes and further testing if symptoms persist.
Variant of uncertain significance (VUS)
May require additional family studies or clinical correlation. Consult genetic counselor for guidance.
If you experience symptoms of hypomagnesemia such as muscle weakness, seizures, or heart issues, or have a family history, consult a healthcare provider for genetic testing and advice.
Limitations
- ⚠Only detects variants in the CLDN19 gene; other genetic causes may not be identified
- ⚠May not detect all types of mutations, such as large deletions
- ⚠Requires genetic counseling for interpretation
Risks & Considerations
- ●Minimal risks from blood draw, such as bruising or infection
- ●Psychological impact of genetic results
- ●No significant risks from FTA card collection
Interfering Factors
- ●Contaminated or degraded sample
- ●Inadequate sample volume
- ●Recent blood transfusion affecting DNA integrity
