Who Should Get This Test

The purpose of this test is to diagnose Ataxia-Oculomotor Apraxia Type 3 by detecting pathogenic mutations in the PIK3R5 gene using NGS technology. It also serves for carrier screening in individuals with a family history of AOA3, aiding in genetic counseling and reproductive planning.

How to Prepare

  • Provide complete clinical history of the patient
  • Undergo a genetic counseling session for pedigree chart of affected family members
  • Collect blood or DNA sample as specified

Doctor's Notes

Test Parameters & Specifications

Sample TypeBlood or Extracted DNA or One drop Blood on FTA Card
Sample Rejection Criteria:
  • Hemolyzed or lipemic samples
  • Insufficient sample volume
  • Improperly labeled or contaminated samples

Understanding Your Results

Test results indicate the presence or absence of pathogenic variants in the PIK3R5 gene, which are associated with Ataxia-Oculomotor Apraxia Type 3.
📊

Normal

No pathogenic variants detected in the PIK3R5 gene; low likelihood of AOA3 based on this gene.

Action: Consider other genetic or environmental causes if symptoms persist; consult with a neurologist or geneticist.

📊

Carrier

One pathogenic variant detected; individual is a carrier for AOA3 but typically asymptomatic.

Action: Genetic counseling recommended for family planning and risk assessment for offspring.

📊

Affected

Two pathogenic variants detected; consistent with diagnosis of AOA3.

Action: Initiate appropriate management, supportive care, and genetic counseling for the patient and family.

⚠️ When to Consult a Doctor:

Consult a healthcare provider if symptoms of ataxia or oculomotor apraxia are present, for carrier screening in families with AOA3 history, or for genetic counseling and management guidance after test results.

Limitations

  • May not detect all types of mutations, such as large deletions or deep intronic variants
  • Results require interpretation in conjunction with clinical findings and genetic counseling
  • Does not rule out other genetic or non-genetic causes of ataxia

Risks & Considerations

  • Minor bruising or pain at the puncture site
  • Rare risk of infection or hematoma

Interfering Factors

  • Poor sample quality or insufficient DNA
  • Contamination during sample collection or processing

Frequently Asked Questions

What is Ataxia-Oculomotor Apraxia Type 3 (AOA3)?
AOA3 is a rare, autosomal recessive genetic disorder that affects the nervous system, causing progressive problems with coordination, eye movements, speech, and muscle control due to mutations in the PIK3R5 gene.
How is AOA3 inherited?
AOA3 is inherited in an autosomal recessive pattern, meaning an individual must inherit two mutated copies of the PIK3R5 gene, one from each parent, to develop the condition.
What are the common symptoms of AOA3?
Symptoms typically begin in childhood or early adulthood and include difficulty with coordination and balance, problems with eye movements (oculomotor apraxia), speech and swallowing difficulties, loss of muscle control, and tremors.
How is the PIK3R5 Gene AOA3 NGS Genetic Test performed?
The test uses next-generation sequencing (NGS) technology to analyze the PIK3R5 gene from a blood or DNA sample, identifying mutations associated with AOA3.
What is the cost of this genetic test?
The cost is INR 20,000, which includes genetic testing, counseling, and support services, with free home sample collection available across India.
Is home sample collection available for this test?
Yes, DNA Labs India offers free home sample collection for online bookings in numerous cities across India.
How long does it take to receive the test results?
Results are typically available within 3 to 4 weeks and can be accessed via online portal, email, or WhatsApp.
Can this test detect carriers of AOA3?
Yes, the test can identify individuals who carry one mutated copy of the PIK3R5 gene, making them carriers for AOA3, which is useful for family planning.
What should I do if the test results are positive?
If positive, consult with a healthcare provider or genetic counselor for management options, supportive care, and family planning advice.
Is genetic counseling provided with this test?
Yes, genetic counseling is included to help interpret results, draw a family pedigree, and discuss implications for the patient and family.
Are there other tests for diagnosing ataxia?
Yes, related tests include those for other genetic ataxias such as ATM, FXN, and SCA genes, which may be recommended based on symptoms and family history.
How can I book the PIK3R5 Gene AOA3 NGS Genetic Test?
You can book the test online through DNA Labs India's website or contact their customer service for assistance with home sample collection and test scheduling.
