Medical notice: this information is for education and service understanding. It is not a diagnosis or a recommendation for an unnecessary procedure.

About this service

High-precision laboratory analysis detecting DNA repeat expansions in the C9ORF72 gene, the primary genetic driver for ALS and related neurodegenerative conditions, facilitating informed clinical decisions.

Purpose of the Procedure

Identifying the genetic basis for Amyotrophic Lateral Sclerosis (ALS).
Evaluating the risk or presence of Frontotemporal Dementia (FTD).
Providing critical genetic risk information for family planning and health monitoring.

How the Test is Performed

A standard blood sample is drawn from a vein.
The sample is processed in a specialized molecular genetics laboratory.
DNA is extracted to measure the number of hexanucleotide repeats in the C9ORF72 gene.

Who Should Consider This Test

Individuals displaying symptoms of motor neuron disease or cognitive decline.
Those with a known family history of ALS or FTD.
Patients requiring genetic confirmation for clinical diagnosis.

What is included?

✓Venous blood sample collection
✓DNA repeat expansion analysis
✓Detailed medical results report

Conditions and notices

Fasting is not required
Providing family medical history is recommended
No need to stop current medications

Frequently Asked Questions

Short answers to the FAQs published with this service.

• What is the C9ORF72 genetic test?

It is a molecular test that looks for specific DNA repeat expansions in the C9ORF72 gene associated with ALS and FTD.

• Is fasting necessary for this test?

No, fasting is not required for this genetic blood test; you can take it at any time.

• Who is a candidate for C9ORF72 analysis?

Individuals with neurological symptoms or those with a family history of ALS or Frontotemporal Dementia.

• Is home collection available for this service?

Yes, we offer home sample collection for this test as it only requires a standard blood draw.

• How does this test benefit my clinical care?

It provides genetic confirmation of a diagnosis, which helps your neurologist tailor your management and support plan.

• What is the expected turnaround time for results?

Genetic sequencing is complex and typically takes a few weeks to complete. You will be notified once the report is ready.
