Description
Familial Genetic Generalised Epilepsies eligibility statement:

Familial Genetic Generalised Epilepsies inclusion criteria (29502)
- Electrographically-proven generalised epilepsy
- At least two first degree relatives or affected family members across three generations who have generalised epilepsy
- All forms of generalised epilepsy are permissible

Familial Genetic Generalised Epilepsies exclusion criteria (29502)
- Suspected acquired cause of epilepsy
- Focal neurological deficit
- MRI demonstrates structural substrate for epilepsy
- EEG demonstrates definite focal discharges

Prior genetic testing guidance (29502)
- Results should have been reviewed for all genetic tests undertaken, including disease-relevant genes in exome sequencing data. The patient is not eligible if they have a molecular diagnosis for their condition. 
- Genetic testing should continue according to routine local practice for this phenotype regardless of recruitment to the project; results of these tests must be submitted via the ‘Genetic investigations’ section of the data capture tool to allow comparison of WGS with current standard testing.  

PLEASE NOTE: The sensitivity of WGS compared to current diagnostic genetic testing has not yet been established. It is therefore important that tests which are clinically indicated under local standard practice continue to be carried out.

Closing statement (29502)
These requirements will be kept under continual review during the main programme and may be subject to change.
