SYN1基因介绍 was created by 凤凰

基因产物:突触蛋白1。

蛋白功能:在成熟神经元中表达,可和突触小泡表面结合,在调控突触神经递质的释放以及在神经元发育中起到一定作用。

相关疾病:X-连锁性癫痫伴可变的学习和行为障碍(XL)( 反射性癫痫 是其最具代表性的临床表现之一,超过一半的病例由接触水(如洗澡)引起)[1-3];X 连锁智力发育障碍(XL)[4]。

相关研究:PubMed数据库(PMID:  21441247 (Hum Mol Genet. 2011) ; PMID:  14985377 (J Med Genet. 2004) ; PMID:  36568968 (Front Cell Dev Biol. 2022) )。

用药提醒:有文献报道 丙戊酸钠 对该基因变异所致的癫痫发作有较好效果,另也有 奥卡西平 拉莫三嗪 舒噻嗪 等使用后癫痫发作消失的报道[3,5]。
