Summaries for Epilepsy, Familial Focal, with Variable Foci 1

NIH Rare Diseases : 54 The following summary is from Orphanet, a European reference portal for information on rare diseases and orphan drugs.Orpha Number: 98820Disease definitionFamilial focal epilepsy with variable foci is a rare genetic epilepsy disorder characterized by autosomal dominant lesional and nonlesional focal epilepsy with variable penetrance. Focal seizures emanate from different cortical locations (temporal, frontal, centroparietal, parietal, parietaloccipital, occipital) in different family members, but for each individual a single focus remains constant throughout lifetime. Seizure type (tonic, tonic-clonic or hyperkinetic) and severity varies among family members and tends to decrease (but do not disappear) during adulthood. Many patients have an aura and show automatisms during diurnal seizures whereas others have nocturnal seizures. Most individuals are of normal intelligence but patients with intellectual disability, autistic spectrum disorder and obsessive-compulsive disorder have been described.Visit the Orphanet disease page for more resources.

MalaCards based summary : Epilepsy, Familial Focal, with Variable Foci 1, also known as ffevf, is related to epilepsy and focal epilepsy. An important gene associated with Epilepsy, Familial Focal, with Variable Foci 1 is DEPDC5 (DEP Domain Containing 5), and among its related pathways/superpathways are mTOR signaling pathway and mTOR signaling pathway (KEGG). Affiliated tissues include brain, temporal lobe and parietal lobe, and related phenotypes are intellectual disability and autistic behavior

Genetics Home Reference : 26 Familial focal epilepsy with variable foci (FFEVF) is an uncommon form of recurrent seizures (epilepsy) that runs in families. Seizures associated with FFEVF can begin at any time from infancy to adulthood. The seizures are described as focal or partial, which means they begin in one region of the brain and do not cause a loss of consciousness. In more than 70 percent of affected individuals, these seizures begin in one of two areas of the brain, either the temporal lobe or the frontal lobe. The region of the brain where the seizures start tends to stay the same over time. In rare instances, seizure activity that starts in one area spreads to affect the entire brain and causes a loss of consciousness, muscle stiffening, and rhythmic jerking. Episodes that begin as partial seizures and spread throughout the brain are known as secondarily generalized seizures.

OMIM : 58 Familial focal epilepsy with variable foci (FFEVF) is an autosomal dominant form of epilepsy characterized by focal seizures arising from different cortical regions in different family members. Many patients have an aura and show automatisms during the seizures, whereas others may have nocturnal seizures. There is often secondary generalization. Some patients show abnormal interictal EEG, and some patients have intellectual disability or autism spectrum disorders. Seizure onset usually occurs in the first or second decades, although later onset has been reported, and there is phenotypic variability within families. Penetrance of the disorder is incomplete (summary by Klein et al., 2012). Detailed electrophysiologic, brain imaging, and/or histologic studies have indicated that some patients have subtle or clear evidence of focal cortical dysplasia (FCD) (Baulac et al., 2015).
