As of 2026-09-125-hydroxytryptamine receptor 2A shows approved-linked disease relevance led by schizophrenia. 5 more disease programs remain visible in the same review block. 32 linked drugs keep the current disease frame grounded. Protein identity stays anchored to UniProt P28223. Start with schizophrenia, then reuse UniProt P28223 as the stable protein anchor across project notes and exports.
5-hydroxytryptamine receptor 2A shows approved-linked disease relevance led by schizophrenia. 5 more disease programs remain visible in the same review block. 32 linked drugs remain visible in the same block.
Start review with schizophrenia because it currently carries approved-linked support. Linked drugs include ARIPIPRAZOLE, ARIPIPRAZOLE LAUROXIL, ASENAPINE MALEATE, BLONANSERIN. This disease block keeps the Open Targets-ready contract explicit while current evidence comes from ChEMBL mechanism and indication mappings.
