As of 2026-09-13

Tyrosine-protein kinase Lck shows approved-linked disease relevance led by chromophobe renal cell carcinoma. 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 P06239. Start with chromophobe renal cell carcinoma, then reuse UniProt P06239 as the stable protein anchor across project notes and exports.

Disease program
chromophobe renal cell carcinoma

Tyrosine-protein kinase Lck shows approved-linked disease relevance led by chromophobe renal cell carcinoma. 5 more disease programs remain visible in the same review block. 1 linked drug remains visible in the same block.

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