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

As of 2026-09-13

Tyrosine-protein kinase SYK shows approved-linked disease relevance led by autoimmune thrombocytopenic purpura. 5 more disease programs remain visible in the same review block. 3 linked drugs keep the current disease frame grounded. Protein identity stays anchored to UniProt P43405. Start with autoimmune thrombocytopenic purpura, then reuse UniProt P43405 as the stable protein anchor across project notes and exports.

Disease program
autoimmune thrombocytopenic purpura

Tyrosine-protein kinase SYK shows approved-linked disease relevance led by autoimmune thrombocytopenic purpura. 5 more disease programs remain visible in the same review block. 3 linked drugs remain visible in the same block.

Start review with autoimmune thrombocytopenic purpura because it currently carries approved-linked support. Linked drugs include FOSTAMATINIB, FOSTAMATINIB DISODIUM, SOVLEPLENIB. This disease block keeps the Open Targets-ready contract explicit while current evidence comes from ChEMBL mechanism and indication mappings.
