Step 1

Sample Collection

Patient should provide detailed clinical history and family history. A genetic counseling session is recommended to draw a pedigree chart and discuss test implications.

Method: Venipuncture

Step 2

Laboratory Analysis

Blood sample collected via venipuncture from a vein in the arm. For FTA card, a finger-prick blood sample may be used. The procedure is quick and minimally invasive.

Step 3

Report Delivery

Apply pressure to the puncture site to stop bleeding. The sample is labeled and sent to the laboratory for analysis. No special post-collection care is required.

Timeline: 3-4 weeks from sample receipt

Patient Instructions

1
Before the Test:Schedule a genetic counseling session to discuss test benefits, limitations, and implications. Provide informed consent for genetic testing.
2
During the Test:Sample collection as per instructions. The test itself is laboratory-based and non-invasive for the patient.
3
After the Test:Wait for 3-4 weeks for results. Genetic counseling session recommended to discuss results, management options, and family implications.

Understanding Your Results

The results of the DNAL4 Gene Mirror Movements Type 3 NGS Genetic Test indicate the presence or absence of mutations in the DNAL4 gene. A positive result confirms the genetic basis for congenital mirror movements, while a negative result may not completely rule out the condition due to technical limitations. Variants of uncertain significance may require further evaluation.
📊

Positive for pathogenic variant

Confirms diagnosis of congenital mirror movements type 3. Genetic counseling and management strategies, such as physical therapy, should be discussed with a specialist.

📊

Negative for pathogenic variant

No mutations detected in DNAL4 gene. Consider other genetic or non-genetic causes. Clinical correlation with symptoms is recommended.

📊

Variant of uncertain significance

A variant was detected but its clinical significance is unknown. Further testing, family studies, or functional assays may be needed for clarification.

⚠️ When to Consult a Doctor:

If the test result is positive, consult a neurologist or geneticist for management and counseling. If symptoms persist despite negative results, seek further neurological evaluation. For family planning or carrier testing, consult a genetic counselor.

Limitations

  • ⚠May not detect all possible mutations in DNAL4 gene
  • ⚠Requires genetic counseling for accurate interpretation
  • ⚠Results should be correlated with clinical findings
  • ⚠Cannot rule out other genetic causes without additional testing

Risks & Considerations

  • ●Minor bruising or discomfort at blood draw site
  • ●Very rare risk of infection at puncture site
  • ●Psychological impact of genetic results, such as anxiety
  • ●Potential for variants of uncertain significance causing confusion

Interfering Factors

  • ●Sample contamination
  • ●Poor DNA quality
  • ●Previous blood transfusions
  • ●Hemolyzed or clotted samples
  • ●Improper sample storage

Frequently Asked Questions

What is the DNAL4 Gene Mirror Movements Type 3 NGS Genetic Test?
This is a genetic test that uses next-generation sequencing (NGS) to identify mutations in the DNAL4 gene, which cause congenital mirror movements type 3, a rare neurological condition characterized by involuntary mirror-like movements.
What is the cost of the test?
The test costs INR 20000.0, and DNA Labs India offers home sample collection across India at no additional charge for online bookings.
How is the test performed?
The test involves collecting a blood sample or extracted DNA, which is analyzed using NGS technology to detect mutations in the DNAL4 gene.
What sample is required for the test?
The test requires a blood sample, extracted DNA, or one drop of blood on an FTA card.
Is fasting required before the test?
No, fasting is not required for this genetic test. However, follow any specific instructions from your healthcare provider.
How long does it take to get results?
Results are typically available within 3 to 4 weeks from the date of sample receipt at the laboratory.
What does a positive result mean?
A positive result confirms the presence of a pathogenic mutation in the DNAL4 gene, diagnosing congenital mirror movements type 3. It helps guide management and genetic counseling.
What does a negative result mean?
A negative result means no pathogenic mutations were detected in the DNAL4 gene. However, it may not rule out the condition entirely, and further evaluation may be needed if symptoms persist.
Are there any risks associated with the test?
The test involves a standard blood draw, with minor risks like bruising or discomfort. There is a very small risk of infection, and psychological impact from results should be considered.
