Frame the target before identity details

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

As of 2026-09-13

Myeloperoxidase shows late clinical disease relevance led by multiple system atrophy. 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 P05164. Start with multiple system atrophy, then reuse UniProt P05164 as the stable protein anchor across project notes and exports.

Disease program
multiple system atrophy

Myeloperoxidase shows late clinical disease relevance led by multiple system atrophy. 3 more disease programs remain visible in the same review block. 1 linked drug remains visible in the same block.

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