早发癫痫性脑病（EIEE）是一类由于频繁癫痫发作及痫性放电导致的严重脑疾病，主要特点为新生儿或婴儿 早期起病，难以控制的癫痫发作及痫性放电，精神运动发育迟滞或倒退。近年来随着分子遗传学的进步，大量新的EIEE相 关性基因突变被发现，使临床对EIEE的遗传学病因及病理生理机制有了更深入的理解。EIEE遗传学研究对了解发病机制、 基因分型、个体化治疗、预后及遗传咨询具有重要意义。文章综述EIEE遗传学病因新进展。

　Early infantile epileptic encephalopathy is a group of disorders affecting children at early stages of infancy, which is characterized by frequent seizures, epileptiform activity on EEG, and developmental retardation or regression. As genetic testing methods advance, an increasing number of novel genetic causes have been uncovered, the genetic etiologies and physiopathologic mechanism of these epileptic syndromes are now better understood. The purpose of this article is to review the progresses in the field of genetic studies in some early infantile epileptic encephalopathies.
