<div class="spaceAbove">Childhood seizures associated with febrile episodes are relatively common and represent the majority of childhood seizures. A febrile convulsion is defined as a seizure event in infancy or childhood, usually occurring between 6 months and 6 years of age, associated with fever but without any evidence of intracranial infection or defined pathologic or traumatic cause (Nabbout et al., 2002). Although the majority of patients do not develop epilepsy, the risk of developing subsequent afebrile seizures is 5 to 7 times higher in those with a history of febrile seizures compared to the general population (Annegers et al., 1987; Hedera et al., 2006).&#13; The FEB1 locus maps to chromosome 8q13-q21.&#13; Genetic Heterogeneity of Familial Febrile Seizures&#13; See FEB2 (602477), caused by mutation in the HCN2 gene (602781) on chromosome 19p13; FEB3A (604403), caused by mutation in the SCN1A gene (182389) on chromosome 2q24; FEB4 (604352), caused by mutation in the ADGRV1 gene (602851) on chromosome 5q14; FEB8 (607681), caused by mutation in the GABRG2 gene (137164) on chromosome 5q31; and FEB11 (614418), caused by mutation in the CPA6 gene (609562) on chromosome 8q13.&#13; Several loci for familial febrile seizures have been identified: see FEB3B (613863) on chromosome 2q24; FEB5 (609255) on chromosome 6q22-q24; FEB6 (609253) on chromosome 18p11; FEB7 (611515) on chromosome 21q22; FEB9 (611634) on chromosome 3p24.2-p23; and FEB10 (612637) on chromosome 3q26.&#13; A phenotype termed 'generalized epilepsy with febrile seizures plus' (GEFS+; 604233) is a clinical subset of familial febrile convulsions in which affected individuals later develop afebrile seizures. GEFS+ is associated with mutations in several genes.&#13; Deprez et al. (2009) provided a review of the genetics of epilepsy syndromes starting in the first year of life, and included a diagnostic algorithm.</div>

<div class="spaceAbove">SCN1A seizure disorders encompass a spectrum that ranges from simple febrile seizures and generalized epilepsy with febrile seizures plus (GEFS+) at the mild end to Dravet syndrome and intractable childhood epilepsy with generalized tonic-clonic seizures (ICE-GTC) at the severe end. Phenotypes with intractable seizures including Dravet syndrome are often associated with cognitive decline. Less commonly observed phenotypes include myoclonic astatic epilepsy (MAE), Lennox-Gastaut syndrome, infantile spasms, epilepsy with focal seizures, and vaccine-related encephalopathy and seizures. The phenotype of SCN1A seizure disorders can vary even within the same family.</div>

<div class="spaceAbove">STXBP1 encephalopathy with epilepsy is characterized by early-onset developmental delay, intellectual disability or cognitive dysfunction, and epilepsy. The median age of onset of seizures is six weeks (range: 1 day to 13 years). Seizure types can include infantile spasms; generalized tonic-clonic, clonic, or tonic seizures; and myoclonic, atonic, absence, and focal seizures. EEG abnormalities can include focal epileptic activity, burst suppression, hypsarrhythmia, or generalized spike-and-slow waves. Other neurologic findings include abnormal tone, movement disorders (especially ataxia and dystonia), and behavioral issues and autism spectrum disorder. Feeding difficulties are common.</div>

<div class="spaceAbove">Multiple congenital anomalies-hypotonia-seizures syndrome-2 (MCAHS2) is an X-linked recessive neurodevelopmental disorder characterized by dysmorphic features, neonatal hypotonia, early-onset myoclonic seizures, and variable congenital anomalies involving the central nervous, cardiac, and urinary systems. Some affected individuals die in infancy (summary by Johnston et al., 2012). The phenotype shows clinical variability with regard to severity and extraneurologic features. However, most patients present in infancy with early-onset epileptic encephalopathy associated with developmental arrest and subsequent severe neurologic disability; these features are consistent with a form of developmental and epileptic encephalopathy (DEE) (summary by Belet et al., 2014, Kato et al., 2014). The disorder is caused by a defect in glycosylphosphatidylinositol (GPI) biosynthesis.&#13; For a discussion of genetic heterogeneity of MCAHS, see MCAHS1 (614080).&#13; For a discussion of nomenclature and genetic heterogeneity of DEE, see 308350.&#13; For a discussion of genetic heterogeneity of GPI biosynthesis defects, see GPIBD1 (610293).</div>

<div class="spaceAbove">KCNT1-related epilepsy is most often associated with two phenotypes: epilepsy of infancy with migrating focal seizures (EIMFS) and autosomal dominant nocturnal frontal lobe epilepsy (ADNFLE). EIMFS is characterized by seizures, typically focal and asynchronous, beginning in the first six months of life with associated developmental plateau or regression. Autonomic manifestations (e.g., perioral cyanosis, flushing, apnea) are common. Seizures are intractable to multiple anticonvulsants and progress to become nearly continuous by age six to nine months. ADNFLE is characterized by clusters of nocturnal motor seizures that vary from simple arousals to hyperkinetic events with tonic or dystonic features. Individuals with KCNT1-related ADNFLE are more likely to develop seizures at a younger age, have cognitive comorbidity, and display psychiatric and behavioral problems than individuals with ADNFLE resulting from other causes. Less common seizure phenotypes in individuals with KCNT1-related epilepsy include West syndrome, Ohtahara syndrome, early myoclonic encephalopathy, leukodystrophy and/or leukoencephalopathy, focal epilepsy, and multifocal epilepsy. Additional neurologic features include hypotonia, microcephaly developing by age 12 months, strabismus, profound developmental delay, and additional movement disorders. Other systemic manifestations including pulmonary hemorrhage caused by prominent systemic-to-pulmonary collateral arteries or cardiac arrhythmia have been reported.</div>

<div class="spaceAbove">GNAO1-related disorder encompasses a broad phenotypic continuum that includes hyperkinetic movement disorders and/or epilepsy and is typically associated with developmental delay and intellectual disability. Viewed by age of onset, three clusters in this continuum can be observed: (1) infantile-onset developmental and epileptic encephalopathy (DEE) with or without prominent movement disorder; (2) infantile- or early childhood-onset prominent movement disorder and neurodevelopmental disorder with or without childhood-onset epilepsy with varying seizure types; (3) later childhood- or adult-onset movement disorder with variable developmental delay and intellectual disability. Epilepsy can be either DEE (onset typically within the first year of life of drug-resistant epilepsy in which developmental delays are attributed to the underlying diagnosis as well as the impact of uncontrolled seizures) or varying seizure types (onset typically between ages three and ten years of focal or generalized tonic-clonic seizures that may be infrequent or well controlled with anti-seizure medications). Movement disorders are characterized by dystonia and choreoathetosis, most commonly a mixed pattern of persistent or paroxysmal dyskinesia that affects the whole body. Exacerbations of the hyperkinetic movement disorder, which can be spontaneous or triggered (e.g., by intercurrent illness, emotional stress, voluntary movements), can last minutes to weeks. Hyperkinetic crises (including status dystonicus) are characterized by temporarily increased and nearly continuous involuntary movements or dystonic posturing that can be life-threatening. Deaths in early childhood have been reported due to medically refractory epilepsy or hyperkinetic crises, but the phenotypic spectrum includes milder presentations, including in adults. As many adults with disabilities have not undergone advanced genetic testing, it is likely that adults with GNAO1-related disorder are underrecognized and underreported.</div>

Short stature, seizures, hearing loss, recurrent infections, microcephaly, and autistic features have also been described in a minority of affected individuals. At least four reported individuals with CTCF-related disorder developed Wilms tumor, one of whom had bilateral Wilms tumor.

Additional more variable features may include poor overall growth with microcephaly, seizures, visual loss, microcytic anemia, and hepatic enlargement or abnormal liver enzymes. Brain imaging shows deep white matter abnormalities consistent with a progressive leukoencephalopathy. The brain and spinal cord are usually both involved; calcifications of these regions are often observed. Laboratory studies show increased serum lactate and deficiencies of mitochondrial respiratory chain complexes, consistent with global mitochondrial dysfunction.
