Useful For
Establishing a diagnosis of an epilepsy or seizure disorder associated with known causal genes
Identifying disease-causing variants within genes known to be associated with inherited epilepsy or seizure disorders, allowing for predictive testing of at-risk family members
Impacting patient treatment and management through the identification of a specific underlying etiology for epilepsy (eg, directing appropriate use of antiepileptic drugs and other treatment modalities)
