Epilepsy, Nocturnal Frontal Lobe, 1; Enfl1

Description

Autosomal dominant nocturnal frontal lobe epilepsy (ENFL, ADNFLE) is a partial epilepsy with frontal lobe seizure semiology. It is characterized by childhood onset of frequent violent and brief motor seizures occurring at night. The disorder may be misdiagnosed as night terrors, nightmares, hysteria, or paroxysmal nocturnal dystonia. The condition usually persists through adult life ({9,8:Scheffer et al., 1994, 1995}). The disorder is clinically distinctive and relatively homogeneous, although seizure severity and specific frontal lobe seizure manifestations vary within families (Hayman et al., 1997). Genetic Heterogeneity of Nocturnal Frontal Lobe EpilepsyNocturnal frontal lobe epilepsy is a genetically heterogeneous condition. See also ENFL2 (OMIM ), which maps to chromosome 15q24; ENFL3 (OMIM ), caused by mutation in the CHRNB2 gene (OMIM ) on chromosome 1q21; ENFL4 (OMIM ), caused by mutation in the CHRNA2 gene (OMIM ) on chromosome 8p21; and ENFL5 (OMIM ), caused by mutation in the KCNT1 gene (OMIM ) on chromosome 9q34.Nocturnal frontal lobe seizures are also observed in some patients with familial focal epilepsy with variable foci (FFEVF ), caused by mutation in the DEPDC5 gene (OMIM ) on chromosome 22q12.
