As of 2026-09-13D(4) dopamine receptor shows approved-linked disease relevance led by psychosis. 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 P21917. Start with psychosis, then reuse UniProt P21917 as the stable protein anchor across project notes and exports.
Start with psychosis, then reuse UniProt P21917 as the stable protein anchor across project notes and exports.
D(4) dopamine receptor shows approved-linked disease relevance led by psychosis. 2 more disease programs remain visible in the same review block. 1 linked drug remains visible in the same block.
Start review with psychosis because it currently carries approved-linked support. Linked drugs include CLOTHIAPINE. This disease block keeps the Open Targets-ready contract explicit while current evidence comes from ChEMBL mechanism and indication mappings.
