Sclerostin

Sclerostin (SOST, chr17q21.31) is an osteocyte-secreted Wnt antagonist; binds LRP5/LRP6 → blocks Wnt/β-catenin → inhibits osteoblast bone formation; romosozumab (anti-sclerostin) has dual anabolic+antiresorptive action: 73% RRR vertebral fractures (FRAME trial).

Also known as: SOST, sclerostin, osteocyte Wnt inhibitor, LRP5/6 antagonist, BMP antagonist
