Key result
SCN8A variants may have gain-of-function (GOF) mechanisms, characterizing the natural history of the disorder compared to other genetic epilepsies.
Why the study?
Despite representing one of the most common epilepsy-associated channelopathies, longitudinal phenotypes of SCN8A-related disorders remain largely uncharacterized.
Cohort
This study characterizes the natural history of SCN8A-related disorders and suggests that variants may have gain-of-function mechanisms, paving the way for precision medicine approaches.
BACKGROUND AND OBJECTIVES: -related disorders encompass a range of neurodevelopmental and epilepsy phenotypes. However, despite representing one of the most common epilepsy-associated channelopathies, its longitudinal phenotypes remain largely uncharacterized. METHODS: -related disorders to reconstruct the natural history of the disorder in comparison with a cohort of 2,833 individuals with known or presumed genetic epilepsies. RESULTS: variants may have GOF mechanisms. DISCUSSION: -related disorders, paving the way for future precision medicine approaches.

Magielski et al. (2025) conducted a cohort in SCN8A-related disorders and genetic epilepsies. SCN8A-related disorders vs. Individuals with known or presumed genetic epilepsies was evaluated on Longitudinal phenotypes and natural history. SCN8A variants may have gain-of-function (GOF) mechanisms, characterizing the natural history of the disorder compared to other genetic epilepsies.
