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-4/beta3/delta shows late clinical disease relevance led by Angelman syndrome. 3 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 P28472. Start with Angelman syndrome, then reuse UniProt P28472 as the stable protein anchor across project notes and exports.

Disease program
Angelman syndrome

Gamma-aminobutyric acid receptor subunit alpha-4/beta3/delta shows late clinical disease relevance led by Angelman syndrome. 3 more disease programs remain visible in the same review block. 1 linked drug remains visible in the same block.

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