GABAA receptor γ2 subunit
Role:  Febrile seizures (OMIM 121210) affect approximately 3% of children under six years of age and are by far the most common seizure disorder. A small proportion of children with febrile seizures later develop ongoing epilepsy with febrile seizures. Segregation analysis suggests that most cases of febrile seizures have complex inheritance, but rare families show apparent autosomal dominant inheritance. Several loci, e.g., FEB1 (121210) on 8q and FEB2 (602477) on 19p, have been related to familial febrile convulsions. Scheffer and Berkovic (1997) and Singh et al. (1999) described a clinical subset, termed 'generalized epilepsy with febrile seizures plus' (GEFS+), in which patients express a highly variable phenotype combining febrile seizures, generalized seizures often precipitated by fever at age 6 years or more, and partial seizures, with a variable degree of severity
