Overview

The purpose of this NGS genetic test is to identify pathogenic variants in the VCP gene associated with ALS type 14. Molecular confirmation helps differentiate ALS type 14 from other forms of ALS and provides a definitive diagnosis for early disease management, genetic counseling, and risk assessment for at-risk family members.

Fasting Required
No
Method
Next-Generation Sequencing (NGS), Variant analysis by ACMG guidelines
Step 1

Sample Collection

Please provide complete clinical history and family pedigree. A genetic counseling session is recommended before blood collection. No fasting is required.

Method: Peripheral venipuncture or FTA card blood spot

Step 2

Laboratory Analysis

A trained phlebotomist will draw blood from a vein in your arm. For FTA card, a drop of blood from a fingerstick will be placed on the card.

Step 3

Report Delivery

You may resume normal activities immediately. The puncture site may be sore for a short time; apply pressure if bleeding persists.

Timeline: Reports are issued in 3 to 4 weeks after receipt of the sample and completion of all quality checks.

Patient Instructions

1
Before the Test:A neurologist or genetic counselor will explain the test, its benefits and limitations, and obtain informed consent.
2
During the Test:A blood sample is collected aseptically or an FTA card is spotted with a drop of blood.
3
After the Test:The sample is securely shipped to the laboratory for NGS. You will be notified when the sample is received and when results are ready.

Understanding Your Results

Results of this test are interpreted by clinical geneticists and reported in line with international ACMG classification. A positive result for a pathogenic/likely pathogenic variant in VCP gene confirms the molecular diagnosis of ALS type 14.
📊

Pathogenic/likely pathogenic variant detected. Consistent with VCP-associated ALS type 14.

Status: Positive

📊

No clinically significant variant identified. ALS may be due to another genetic or non-genetic cause.

Status: Negative

📊

Variant of uncertain significance. Additional familial testing and functional studies may be needed.

Status: VUS

⚠️ When to Consult a Doctor:

If you or a family member have symptoms such as muscle weakness, slurred speech, swallowing problems, or breathing difficulty, consult a neurologist at the earliest. Genetic testing should be done under medical supervision.

Limitations

  • This test analyzes only the VCP gene; other ALS-associated genes are not assessed.
  • Regulatory, deep intronic or large structural variants may not be detected.
  • Variant of uncertain significance (VUS) may require additional familial testing or functional studies.
  • This test cannot assess the progression rate or severity of ALS.

Risks & Considerations

  • Slight pain or bruising at the venipuncture site
  • Very low risk of infection
  • Psychological impact of a genetic diagnosis

Interfering Factors

  • Low DNA yield or poor sample quality
  • Contamination or maternal cell admixture
  • Incomplete coverage of GC-rich regions
  • Use of anticoagulants other than EDTA

Frequently Asked Questions

What is ALS type 14?
ALS type 14 is a rare inherited form of amyotrophic lateral sclerosis caused by mutations in the VCP gene. It affects motor neurons and leads to progressive muscle weakness, speech and swallowing issues, and respiratory failure.
What is the VCP gene?
The VCP gene encodes valosin-containing protein, involved in protein degradation. Mutations disrupt protein clearance, causing neurotoxicity and ALS.
How is ALS type 14 diagnosed?
Diagnosis is confirmed by NGS genetic testing of the VCP gene. Neurological examination, EMG, and ruling out other conditions are also part of the diagnostic workup.
What is NGS genetic testing?
Next-generation sequencing is a high-throughput technology that rapidly sequences multiple DNA regions, enabling accurate detection of genetic variants in the VCP gene.
How long does the test take?
Results typically take 3 to 4 weeks from the time the sample reaches the laboratory.
What is the cost of the test?
The all-inclusive cost is INR 20,000, which covers sample collection, testing, genetic counseling, and interpretation.
Is home sample collection available?
Yes, DNA Labs India provides free home sample collection in many cities across India for online bookings.
What kind of sample is required?
A blood sample, extracted DNA, or one drop of blood on an FTA card can be used for testing.
Does this test require fasting?
No, fasting is not required for this genetic test.
What does a positive result mean?
A positive result means a pathogenic or likely pathogenic variant in the VCP gene was identified, confirming the molecular diagnosis of ALS type 14.
Should I have genetic counseling before testing?
Yes, a genetic counseling session is recommended before and after testing to understand the implications of results for you and your family.
Can this test be used for at-risk relatives?
Yes, once a pathogenic variant is identified in a family, predictive testing can be offered to asymptomatic adult relatives after appropriate counseling.
