Familial partial epilepsy with variable foci: a new family with suggestion of linkage to chromosome 22q12.
Familial partial epilepsy with variable foci (FPEVF) is an autosomal dominant form of partial epilepsy characterized by the presence of epileptic seizures originating from different cerebral lobes in different members of the same family. Linkage to chromosomes 22q12 and 2q36 has been reported, although only six families have been published. We studied a new FPEVF family including nine affected individuals. The phenotype in this family was similar to that previously described and consisted of nocturnal and daytime seizures with semiology suggesting a frontal lobe origin. A video-EEG (electroencephalography) recording of the proband's seizures is presented and revealed hyperkinetic seizures of frontal lobe origin preceded by left frontal spikes. We excluded linkage to chromosome 2q36 and found a suggestion of linkage to chromosome 22q12 with a lod score of 2.64 (h = 0) for marker D22S689.
