GEFS
Generalized epilepsy with febrile seizures plus (GEFS+) is a syndromic autosomal dominant disorder where affected individuals can exhibit numerous epilepsy phenotypes. GEFS+ can persist beyond early childhood (i.e., 6 years of age). GEFS+ is also now believed to encompass three other epilepsy disorders: severe myoclonic epilepsy of infancy (SMEI), which is also known as Dravet's syndrome, borderline SMEI (SMEB), and intractable epilepsy of childhood (IEC). There are at least six types of GEFS+, delineated by their causative gene. Known causative gene mutations are in the sodium channel α subunit genes SCN1A, an associated β subunit SCN1B, and in a GABAA receptor γ subunit gene, in GABRG2 and there is another gene related with calcium channel the PCDH19 which is also known as Epilepsy Female with Mental Retardation. Penetrance for this disorder is estimated at 60%. Signs and symptoms Individuals with GEFS+ present with a range of epilepsy phenotypes. These include febri ...

Epilepsy Female Restricted
Epilepsy-intellectual disability in females also known as PCDH19 gene-related epilepsy or epileptic encephalopathy, early infantile, 9 (EIEE9), is a rare type of epilepsy that affects predominantly females and is characterized by clusters of brief seizures, which start in infancy or early childhood, and is occasionally accompanied by varying degrees of cognitive impairment. The striking pattern of onset seizures at a young age, genetic testing and laboratory results, potential developmental delays or developmental regression and associated disorders, eases diagnosis. The National Institutes of Health Office and Rare Disease Research characterizes PCDH19 gene-related epilepsy as a rare disorder. Although formal epidemiologic data is not available, results from diagnostic screenings indicate that approximately 1 out of 10 girls who have seizure onset before five years of age may have PCDH19 mutations. Signs and symptoms PCDH19 gene-related epilepsy is a highly variable and rare ep ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
