SYN1
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]。
突变数据库:ClinVar数据库。
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]。
