遗传性癫痫和发育性脑病 (DEE) 的精准医学

神经发育性和癫痫性脑病 (DEE) 的精准医学旨在针对患者遗传变异背后的病理生理学和分子机制进行药物治疗，避免无效或有害的治疗。

代表治疗方法的临床细分

表中所示的主要分子类别和治疗靶点详述如下：

1. 钠和钾通道病

  • SCN1A（Dravet 综合征 - 功能丧失）： 精确接近 芬氟拉明、大麻二酚、司替戊醇、氯巴扎姆和丙戊酸. 精度警报： 由于存在严重恶化和难治性癫痫发作的风险，钠通道阻滞剂（卡马西平、苯妥英、拉莫三嗪）被正式禁用。
  • SCN2A 和 SCN8A（早期首次亮相的功能变体增益）： 优先指示 钠通道阻滞剂 高剂量（苯妥英、卡马西平）可恢复膜过度兴奋。
  • KCNQ2 / KCNQ3（Kv7.2/Kv7.3 钾通道）： 选择性开放K+通道 瑞替加滨（ezogabine） 以及早期阶段对卡马西平等钠阻滞剂的良好反应。
  • KCNT1（Na+依赖性钾通道）： 使用 奎尼丁 作为难治性儿童移行性局灶性癫痫的特定标签外调节剂。

2. 代谢和脑运输障碍

  • SLC2A1（脑葡萄糖转运蛋白 GLUT1 缺乏症）： 强制替代治疗 生酮饮食 早期，提供酮体作为葡萄糖的替代脑能量底物。
  • ALDH7A1 / PNPO（吡哆醇依赖性癫痫）： 特定的终身补充 吡哆醇（维生素 B6） o 5′-磷酸吡哆醛 (PLP).

3. mTORopathies 和增殖/信号通路

  • TSC1/TSC2（结节性硬化症复合体）和 DEPDC5/NPRL2/NPRL3（GATOR1 复合体）： 细胞内 mTOR 级联的过度激活。有针对性的方法 mTOR 抑制剂（依维莫司、西罗莫司） 用于控制癫痫发作和相关的局灶性皮质发育不良。

4. 受体和突触通路的调节器

  • GRIN2A / GRIN2B（NMDA 受体亚基）： 通过变构调节和阻断 NMDA 受体 美金刚 具有功能增益的变体。
  • PCDH19（原钙粘蛋白 19）： 神经类固醇调节疗法（加奈索酮）和特定的激素方案。
