Broader Open DB context

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

Phosphatidylinositol 4,5-bisphosphate 3-kinase catalytic subunit beta isoform shows clinical signal disease relevance led by lymphoma. 5 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 P42338. Start with lymphoma, then reuse UniProt P42338 as the stable protein anchor across project notes and exports.

lymphoma

Phosphatidylinositol 4,5-bisphosphate 3-kinase catalytic subunit beta isoform shows clinical signal disease relevance led by lymphoma. 5 more disease programs remain visible in the same review block. 1 linked drug remains visible in the same block.

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