Structured disease, protein, and project context should read before the lower-level identity rail.

As of 2026-09-13

Gamma-aminobutyric acid receptor subunit alpha-1 shows late clinical disease relevance led by depressive disorder. 1 more disease program remain visible in the same review block. 1 linked drug keeps the current disease frame grounded. Protein identity stays anchored to UniProt P14867. Start with depressive disorder, then reuse UniProt P14867 as the stable protein anchor across project notes and exports.

Disease program
depressive disorder

Gamma-aminobutyric acid receptor subunit alpha-1 shows late clinical disease relevance led by depressive disorder. 1 more disease program remain visible in the same review block. 1 linked drug remains visible in the same block.

Start review with depressive disorder because it currently carries late clinical support. Linked drugs include INDIPLON. This disease block keeps the Open Targets-ready contract explicit while current evidence comes from ChEMBL mechanism and indication mappings.
