As of 2026-09-135-hydroxytryptamine receptor 6 shows late clinical disease relevance led by Alzheimer disease. 3 more disease programs remain visible in the same review block. 5 linked drugs keep the current disease frame grounded. Protein identity stays anchored to UniProt P50406. Start with Alzheimer disease, then reuse UniProt P50406 as the stable protein anchor across project notes and exports.
5-hydroxytryptamine receptor 6 shows late clinical disease relevance led by Alzheimer disease. 3 more disease programs remain visible in the same review block. 5 linked drugs remain visible in the same block.
Start review with Alzheimer disease because it currently carries late clinical support. Linked drugs include CERLAPIRDINE, IDALOPIRDINE, INTEPIRDINE, MASUPIRDINE. This disease block keeps the Open Targets-ready contract explicit while current evidence comes from ChEMBL mechanism and indication mappings.
