No-cost epilepsy gene panel testing program

Invitae and BioMarin have partnered to offer no-cost Invitae Epilepsy Panel testing for children 2 to 4 years of age, who experienced their first unprovoked seizure after the age of 2 years.

An epilepsy gene panel test can bring you and your patients closer to identifying the genetic cause behind the seizure, thereby shortening the diagnostic odyssey and potentially impacting clinical management.

  • More than 50% of epilepsies have some genetic basis, and early testing may be the most direct, cost-effective, and accurate diagnostic tool.1
  • Not all seizures are benign, and genetic testing can help to rule out or confirm a suspected diagnosis or uncover a rare or fatal disease. Learn more about CLN2 disease and why early diagnosis is essential for patients with this disorder.
  • Many genes are actionable, and early diagnosis is critical as it can inform treatment decisions.
