PRRT2基因介绍 was created by 凤凰

基因产物:富含脯氨酸跨膜蛋白2。

蛋白功能:作为AMPAR复合物体的一个组成部分,参与中枢神经系统突触的传递[1]

相关疾病:家族性婴儿惊厥伴发作性舞蹈手足徐动症(AD)[2];发作性运动诱发性运动障碍(AD)[3]; 自限性家族性婴儿癫痫 (AD)[2];偏瘫性偏头痛[4]; 婴儿癫痫伴游走性局灶性发作 [5]。

相关临床研究:PubMed数据库(PMID:  26446061(Neurology. 2015) ; PMID: 25520928 (Biomedicine (Taipei). 2014) ; PMID: 23535490 (Neurology. 2013)

用药提醒PRRT2突变所致的发作性运动诱发性运动障碍(PKD)往往对小剂量的 卡马西平 就会有很好的效果。
