As of 2026-09-13

Bone morphogenetic protein receptor type-1A shows approved-linked disease relevance led by bone disease. 5 more disease programs remain visible in the same review block. 2 linked drugs keep the current disease frame grounded. Protein identity stays anchored to UniProt P36894. Start with bone disease, then reuse UniProt P36894 as the stable protein anchor across project notes and exports.

Bone morphogenetic protein receptor type-1A shows approved-linked disease relevance led by bone disease. 5 more disease programs remain visible in the same review block. 2 linked drugs remain visible in the same block.

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