Frame the target before identity details

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

As of 2026-09-14

Caspase-9 shows clinical signal disease relevance led by hepatitis C virus infection. 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 P55211. Start with hepatitis C virus infection, then reuse UniProt P55211 as the stable protein anchor across project notes and exports.

Disease program
hepatitis C virus infection

Caspase-9 shows clinical signal disease relevance led by hepatitis C virus infection. 1 more disease program remain visible in the same review block. 1 linked drug remains visible in the same block.

Start review with hepatitis C virus infection because it currently carries clinical signal support. Linked drugs include NIVOCASAN. This disease block keeps the Open Targets-ready contract explicit while current evidence comes from ChEMBL mechanism and indication mappings.
