Sample Collection
No fasting is required for this genetic test. Please carry a valid ID and relevant medical records. A genetic counseling session may be performed before sample collection to draw a pedigree chart.
Method: Peripheral venipuncture / FTA card / DNA extraction
Laboratory Analysis
A small amount of blood will be collected from a vein in your arm, or an FTA card spot or extracted DNA sample may be provided as per laboratory instructions.
Report Delivery
You can resume normal activities immediately. The sample will be transported to the laboratory for NGS analysis. Your clinical report will be shared in 3 to 4 weeks.
Timeline: 3 to 4 weeks from sample receipt.

Doctor's Notes
Reviewed by Dr Pasupathy Arumugam — MBBS, MD (Pathology) · Reg. No. 21521
"Genetic counselling is essential before and after testing to document the family pedigree, explain inheritance risk, and support reproductive and clinical decisions."

Test Parameters & Specifications
Sample Stability
- Hemolysed or clotted blood
- Insufficient sample quantity
- Incorrectly labelled sample
- Sample received at extreme temperature or after prolonged transit without proper preservation
Understanding Your Results
Pathogenic variant detected
Action: Confirms diagnosis of CTNNA2-related neuronal migration disorder. Genetic counselling and family screening advised.
Likely pathogenic variant detected
Action: Highly suggestive of causal variant; additional family studies may be needed.
Variant of uncertain significance
Action: Further testing of family members may help reclassify the variant.
No pathogenic variant detected
Action: Does not rule out CTNNA2 disorder; clinical correlation and other gene panels may be considered.
If the patient has epilepsy, intellectual disability, developmental delay, or suspected neuronal migration disorder on neuroimaging, discuss this test with a neurologist or geneticist.
Limitations
- ⚠NGS may not detect all types of variants, such as large deletions/duplications, deep intronic changes, or epigenetic abnormalities.
- ⚠A negative result does not exclude all genetic causes of neuronal migration disorder.
- ⚠Variant of uncertain significance may require further family segregation studies.
Risks & Considerations
- ●Minor pain or bruising at the blood collection site
- ●Light headedness during blood draw
Interfering Factors
- ●Poor quality or quantity of extracted DNA
- ●Hemolyzed or clotted blood sample
- ●Sample mix-up or labelling error
- ●Presence of interfering maternal cell contamination
