GRIN2A基因介绍 was created by 凤凰

基因产物:N-甲基-D-天门冬氨酸受体(NMDA)亚单位2A。

蛋白功能:属于NMDA受体复合物的组成部分,该受体属于配体门控的离子型谷氨酸受体,在中枢神经系统中广泛表达,介导兴奋性突触传递过程中的慢钙电流成分,在突触传递的长时程增强中起重要作用,和学习和记忆形成有关[1, 2]。

相关疾病: 伴中央颞区棘波的儿童癫痫 (原先习惯叫BECT), 不典型儿童癫痫伴中央颞区棘波 (原先习惯叫BECT变异型Ⅰ型), Landau-Kleffner 综合征 癫痫性脑病伴慢波睡眠期持续棘慢波 (AD)[3, 4], West 综合征 [5]。

相关临床研究:PubMed数据库(PMID: 28109652 (Eur J Paediatr Neurol. 2017) )
