Test ID: ESPAN    
Epilepsy/Seizure Genetic Panels by Next Generation Sequencing (NGS)

Useful For Suggests clinical disorders or settings where the test may be helpful

Establishing a diagnosis of an epilepsy or seizure disorder associated with known causal genes


Identifying mutations within genes known to be associated with inherited epilepsy or seizure disorders, allowing for predictive testing of at-risk family members

Genetics Test Information Provides information that may help with selection of the correct genetic test or proper submission of the test request

Epilepsy is a heterogeneous group of disorders that are characterized by recurrent and usually unprovoked seizures.


This test includes the option of performing 1 of several epilepsy/seizure-related panels. Options include the following:

-Early Epileptic Encephalopathy Panel (90 genes)

-Encephalopathy with Seizures Panel (129 genes)

-Epilepsy Expanded Panel (192 genes)

-Epilepsy with Migraine Panel (7 genes)

-Febrile Seizure Panel (9 genes)

-Focal Epilepsy Panel (16 genes)

-Infantile Spasms Panel (17 genes)

-Neuronal Migration Disorders Panel (29 genes)

-Progressive Myoclonic Epilepsy Panel (27 genes)

-Tuberous Sclerosis Panel (2 Genes)

-Custom Gene Panel (https://orders.mayomedicallaboratories.com/en/tools/gene_panels)

Testing Algorithm Delineates situations when tests are added to the initial order. This includes reflex and additional tests.

This test includes the option for either 1 of several predefined panel tests or the option to create a custom gene panel. Pricing for the Custom Gene Panel will be based on the number of genes selected (1, 2-10, 11-49, 50-100, and 101-500).
