N-乙酰谷氨酸合成酶缺乏所致高氨血症
Hyperammonemia due to N-acetylglutamate synthase deficiency
定义 英文原文(暂无中文)
A rare disorder of urea cycle metabolism causing a deficit of ammonia detoxification and arginine synthesis, and characterized by hyperammonemia of variable severity. Manifestations range from neonatal presentation of poor feeding, vomiting, lethargy, tachypnea, convulsions and coma to adult-onset headaches, hazy gastrointestinal symptoms, seizures, behavioral/psychiatric problems, confusion and lethargy.

境外已获批用于本病的药物 0L2
欧盟与美国均未检索到已获批用于本病的药物。
已获孤儿药资格、尚未获批的在研药物(2 项)
孤儿药资格只是一种监管身份——它意味着监管机构认可这是罕见病用药并给予研发激励,不代表这个药已被证明有效,也不代表将来一定能上市。绝大多数最终不会成药。列在这里是为了看清有哪些方向正在被尝试。
数据来自欧洲药品管理局(EMA)的药品与孤儿药资格公开导出表,以及美国 FDA 孤儿药资格数据库。两边口径不同:欧盟一侧取的是当前状态仍为「已授权」的药品;美国一侧记录的是「曾获批准」这一事实,FDA 的公开表不追踪药物此后是否退市(例如 Relyvrio 于 2024 年撤市,表中仍记为已获批)。请以官方记录页为准。
