Genetics and epilepsy

The term "epilepsy" describes a heterogeneous group of disorders, most of them caused by interactions between several or even many genes and environmental factors. Much rarer are the genetic epilepsies that are due to single-gene mutations or defined structural chromosomal aberrations, such as microdeletions. The discovery of several of the genes underlying these rare genetic epilepsies has alr...

Epilepsy and Genetics

Epilepsy is one of the most common neurological disorder, that affects approximately 50 million people in the world and 90% of epilepsy cases are seen in the less developed coun‐ tries[1,2].Epilepsy and seizures affect nearly 3 million Americans of all ages.Inheritance as etiology for epilepsy has been suspected for centuries. Despite the frequency of seizure dis‐ order and epilepsy little prog...

Genetics in Epilepsy

Genetics of epilepsy.

The last decade has witnessed rapid advances in understanding the role of genetic factors in epilepsy. Mutations and chromosomal defects underlying many inherited symptomatic epilepsies have now been identified, and several genes have been associated with rare idiopathic epilepsies transmitted in a mendelian manner. However, the genetic factors underlying inherited susceptibility to idiopathic ...

Genetics of childhood epilepsy.

The epilepsies are a heterogeneous group of disorders with many causes. However, a genetic aetiology may be present in up to 40% of patients, and this proportion is even higher in epilepsy of childhood onset. The past decade has seen spectacular advances in our understanding of the genetics of epilepsy at a molecular level, and several comprehensive reviews are available. 3 It is apparent that ...
