Idiopathic generalized epilepsy (IGE) is characterized by recurring generalized seizures in the absence of detectable brain lesions and/or metabolic abnormalities. Twin and family studies suggest that genetic factors play a key part in IGE. A multilocus model appears to best fit the observed inheritance patterns. Mapping of IGE-related genes has been previously attempted using parametric methods, with conflicting results. In particular, recent evidence argues both for and against a chromosome 6p locus (EJM1) for juvenile myoclonic epilepsy, a subtype of IGE. We have approached the problem of mapping IGE loci using non-parametric methods, which have recently been successful for other complex diseases. No evidence for linkage to chromosome 6p was obtained. However, we obtained evidence for involvement of a locus at chromosome 8q24, close to the marker D8S256. The same 8q24 region was previously implicated in families with benign neonatal familial convulsions (BNFC), a generalized epilepsy syndrome that is inherited as a simple dominant mendelian trait. There is an apparent conserved syntenic group of genes in human 8q24 and a region of mouse chromosome 15, which harbors the stargazer (stg) locus. Homozygous mutant mice at the stg locus show a form of generalized epilepsy that resembles human absence epilepsy. Our findings may have implications for a locus on 8q24 predisposing to IGE.

Epilepsy is one of the most common neurological disorders. Both inherited and acquired factors contribute to its multifactorial pathogenesis. A genetic predisposition plays a major role in the aetiology of the common idiopathic generalized epilepsies. Susceptibility genes for two syndromes of idiopathic generalized epilepsies, the benign familial neonatal convulsions and juvenile myoclonic epilepsy, have been assigned to the chromosomal regions 20q13 (EBN1), 8q24 (EBN2) and 6p21 (EJM1). Positional cloning of the mutations causing these traits will help to elucidate the molecular pathways of epileptogenesis and will imply a classification on a neurobiological basis. Insights into the underlying impairment of neuronal excitability should provide new concepts for the development of rational treatment strategies.
