Epilepsy encompasses a range of seizure disorders. Genetic factors play a role in many types particularly in childhood-onset epilepsies.
How Genetic Is Epilepsy?
Genetics plays a meaningful role in Epilepsy, with heritability estimated at around 32%. However, environmental factors — including diet, lifestyle, and exposure — also significantly influence risk.
Key genes associated with Epilepsy: SCN1A,SCN2A,KCNQ2,GABRA1. Variants in these genes have been identified through genome-wide association studies (GWAS) and clinical research as influencing susceptibility or severity.
