Structured disease, protein, and project context should read before the lower-level identity rail.
As of 2026-09-14Sodium- and chloride-dependent GABA transporter 1 shows approved-linked disease relevance led by Seizure. 2 more disease programs remain visible in the same review block. 1 linked drug keeps the current disease frame grounded. Protein identity stays anchored to UniProt P30531. Start with Seizure, then reuse UniProt P30531 as the stable protein anchor across project notes and exports.
Sodium- and chloride-dependent GABA transporter 1 shows approved-linked disease relevance led by Seizure. 2 more disease programs remain visible in the same review block. 1 linked drug remains visible in the same block.
Start review with Seizure because it currently carries approved-linked support. Linked drugs include TIAGABINE HYDROCHLORIDE. This disease block keeps the Open Targets-ready contract explicit while current evidence comes from ChEMBL mechanism and indication mappings.
