Germline Genetic Variants and Epilepsy Surgery Response: Individual Participant Pooled Analysis of 272 Patients.

What was studied

This pooled analysis looked at seizure outcomes after epilepsy surgery. The people had inherited gene changes. It used 272 people in all. Of these, 224 came from papers and 36 from hospital records. A research network gave 12. The main outcome was being seizure-free at last follow-up. The median follow-up was 24 months.

What they found

Seizure freedom differed by cause. It was highest in vascular disorders, 14 of 19 people. It was 79 of 120 in GATORopathies. It was lowest in channelopathies, 13 of 43, and synaptopathies, 4 of 18. Most people had lesions on MRI. These patterns held in checks.

What it means for patients

The authors say resective surgery can be effective in these inherited epilepsies. They say outcomes vary by pathway. Disorders with clear lesions showed the highest chance of seizure freedom. These include GATORopathies and vascular ones.

Why it is not certain yet

Most cases came from published reports. The groups were small. The median follow-up was 24 months. The authors call for registries with standard reports. These would help refine how surgery candidates are chosen.
