Overview
The purpose of the LGMD genetic test is to identify pathogenic variants in genes associated with Limb-Girdle Muscular Dystrophy. This test helps confirm a clinical diagnosis, differentiate LGMD from other neuromuscular disorders, determine the genetic subtype, and provide information for genetic counseling and family planning. It also aids in predicting disease progression and potential complications, enabling proactive management.

Understanding Your Results
Pathogenic variant detected
Confirms the diagnosis of LGMD. Genetic counseling is recommended for family members.
Variant of uncertain significance (VUS)
Further testing or family segregation analysis may be needed to clarify significance.
No pathogenic variant detected
Does not rule out LGMD; other genetic or non-genetic causes should be considered.
Consult a geneticist or neurologist if you have symptoms suggestive of LGMD, a family history of the condition, or if you have received a positive genetic test result. Early consultation can help in management and family planning.
Limitations
- ⚠This test may not detect all possible genetic mutations; some rare variants may be missed.
- ⚠Variants of uncertain significance may be reported; additional testing or family studies may be needed.
- ⚠The test does not assess disease severity or progression; clinical correlation is required.
Risks & Considerations
- ●Minimal risk of bruising or infection at the puncture site
- ●Rare possibility of fainting during blood draw
Interfering Factors
- ●Recent blood transfusion may affect DNA analysis
- ●Bone marrow transplantation can lead to mixed DNA results
- ●Insufficient sample quantity or poor sample quality

|---|---|---|---|---|
| Comparison | Limb-Girdle Muscular Dystrophy | Invasive procedure, may show dystrophic changes but not specific to LGMD subtype. Genetic testing is more definitive. | Elevated CK indicates muscle damage but is not specific to LGMD. Genetic testing confirms the diagnosis. | Targeted to one gene, may miss other LGMD subtypes. Our panel covers multiple genes for comprehensive analysis. |
