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

As of 2026-09-14

4-hydroxyphenylpyruvate dioxygenase shows approved-linked disease relevance led by tyrosinemia. 2 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 P32754. Start with tyrosinemia, then reuse UniProt P32754 as the stable protein anchor across project notes and exports.

4-hydroxyphenylpyruvate dioxygenase shows approved-linked disease relevance led by tyrosinemia. 2 more disease programs remain visible in the same review block. 1 linked drug remains visible in the same block.

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