基因产物：TBC1域家族蛋白成员24。

蛋白功能：可作为Rab家族蛋白的GTPase激活蛋白参与神经元投射的发育以及突触囊泡运输的调节[8-10]。

相关疾病：常染色体隐性遗传耳聋（AR）[1]；常染色体显性遗传耳聋（AD）[2]；DOORS 综合症（AR）[3]； 婴儿癫痫伴游走性局灶性发作 （AR）[4]；家族性 婴儿肌阵挛癫痫 （AR）[5]；Rolandic癫痫伴运动诱发性肌张力障碍（AR）[6]； Dravet 综合征 （AR）[7]； 进行性肌阵挛癫痫 （AR）[7]； West 综合征 [11]。

相关基础研究：转基因小鼠模型（PMID:  30335140 (Hum Mol Genet. 2019) ；PMID:  30602030 (Hum Mol Genet. 2019) ）

相关临床研究：PubMed数据库（PMID: 27281533 (Neurology. 2016) ）

用药提醒：基于目前报道的该基因变异可能导致的一些癫痫综合征及发作类型来看不建议优先考虑卡马西平、奥卡西平等这类窄谱的抗癫痫药物，部分病人有可能反而会加重（仅个人建议，只供参考）。
