Behind the Seizure Australia

Test early to expedite care

Sponsored epilepsy gene panel testing program

Invitae, BioMarin Pharmaceutical Australia Pty Ltd., PTC Therapeutics, and Xenon Pharmaceuticals Inc. have partnered to offer Invitae's comprehensive Epilepsy Panel to any child under 5 years (<60 months) of age who has had an unprovoked seizure.

An epilepsy gene panel can bring you closer to understanding what’s causing your patient’s epilepsy, helping your patients and their caregivers benefit from deeper knowledge and timely care.

  • More than 50% of epilepsies have some genetic basis.1 
    When a patient presents with seizures, genetic testing may help identify if there is an underlying genetic cause.

  • Many of these genetic variants are tied to actionable medical management. 
    Identifying a seizure’s underlying etiology may enable disease-specific management strategy.1

  • Delay can be devastating for patients with genetic epilepsy. 
    Early diagnosis is critical. Genetic testing can help identify the cause of epilepsy before a patient experiences the hallmark signs of regression.2

  • Genetic epilepsies may be hiding behind non-specific symptoms.  
    Language delay and motor disturbance may be useful predictors of finding genetic epilepsies.3


Ordering instructions

Program eligibility

  • Any child under 5 years (<60 months) of age who has had an unprovoked seizure

  • Only specimen samples from Australia are accepted for this program.

Invitae Epilepsy Panel

The Invitae Epilepsy Panel offers a broad and comprehensive analysis for genetic epilepsy, which includes genes associated with both syndromic and non-syndromic causes of epilepsy, including neurodegenerative conditions.

Turnaround time for the panel is rapid. Once Invitae receives the sample, you will receive results within 10 to 21 calendar days, on average.

Precision medicine implications from genetic testing in childhood epilepsy 

  • Among nearly 10,000 patients with epilepsy, 14.9% to 24.4% received a definitive molecular diagnosis from lnvitae genetic testing.4

  • More than half of these diagnoses were in children younger than 5 years.4 

  • Precision medicine implications were identified in 33% of individuals with a positive test result.4
