No-cost epilepsy gene panel testing program

Invitae and BioMarin have partnered to offer no-cost Invitae Epilepsy Panel testing for 2–4 year olds that meet the patient eligibility requirements to ensure patients benefit from genetic insights early in their care.

Genetic research is rapidly advancing our understanding of the underlying causes of epilepsy and clinical implications for disease management. In as little as 2 weeks, an epilepsy gene panel test can bring you and your patients closer to identifying the genetic cause behind the seizure. Determining a genetic basis of disease for children with unprovoked seizures has the potential to impact clinical management.
