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

As of 2026-09-13

Transthyretin shows approved-linked disease relevance led by amyloidosis. 5 more disease programs remain visible in the same review block. 4 linked drugs keep the current disease frame grounded. Protein identity stays anchored to UniProt P02766. Start with amyloidosis, then reuse UniProt P02766 as the stable protein anchor across project notes and exports.

Disease program
amyloidosis

Transthyretin shows approved-linked disease relevance led by amyloidosis. 5 more disease programs remain visible in the same review block. 4 linked drugs remain visible in the same block.

Start review with amyloidosis because it currently carries approved-linked support. Linked drugs include ACORAMIDIS, ACORAMIDIS HYDROCHLORIDE, TAFAMIDIS, TAFAMIDIS MEGLUMINE. This disease block keeps the Open Targets-ready contract explicit while current evidence comes from ChEMBL mechanism and indication mappings.
