The list of laboratories provided does not include all laboratories that perform paediatric epilepsy diagnostic testing. These laboratories are affiliated with BioMarin and participate in commercially sponsored diagnostic testing programmes. There may or may not be a sponsored programme or test in your area.
In paediatric patients with seizures of unknown cause, consider:

- Gene panel molecular testing in the case of general suspicion of a genetic aetiology of epilepsy. A comprehensive epilepsy gene panel can analyze up to hundreds of genes linked to genetic epilepsy and neurodegenerative diseases such as CLN2 in one test.3,4 Please note, if you decide to use your local hospital testing facility, please ensure TPP1/CLN2 gene is included in all epilepsy targeted panels.

- TPP1 enzyme testing in the case of a high suspicion of CLN2 disease. A simple blood test can confirm or rule out deficiency of TPP1 enzyme that causes CLN2 disease (in the case of a positive result a molecular/DNA confirmation of variants in the TPP1 gene is recommended for confirming diagnosis).3
