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

As of 2026-09-14

Melanocortin receptor 3 shows clinical signal disease relevance led by Acute kidney injury. 1 more disease program remain visible in the same review block. 1 linked drug keeps the current disease frame grounded. Protein identity stays anchored to UniProt P41968. Start with Acute kidney injury, then reuse UniProt P41968 as the stable protein anchor across project notes and exports.
