Boillot et al. (2015) reported 5 families with inherited GABRG2 variants who had febrile seizures and temporal lobe epilepsy. One patient (p.P302L) who experienced febrile seizures, multiple seizure types, and early psychomotor and language developmental delay was diagnosed with Dravet syndrome (Hernandez et al., 2017). This evidence concerns the gene GABRG2 and encephalopathy, progressive, early-onset, with brain edema and/or leukoencephalopathy.
