Epilepsies with single gene inheritance

Abstract

Single gene disorders offer the best opportunity for identification of genetic linkage and of abnormal genes. Epilepsies with single gene inheritance include symptomatic epilepsies where there is associated diffuse brain dysfunction, and idiopathic epilepsies where seizures are the major neurological abnormality. There are over 200 single gene symptomatic epilepsies; most are rare. Gene identification has been achieved in a number of these conditions but these important advances have not yet led to a better understanding of epileptogenesis, because of the associated brain disease. Idiopathic single gene epilepsies include benign familial neonatal convulsions, where genetic linkage to chromos..
