PRRT2
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]。
突变数据库:ClinVar数据库。
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。
