Abstract

Context: The role and importance of circulating sclerostin is poorly understood. High Bone Mass (HBM) caused by activating LRP5 mutations has been reported to be associated with increased plasma sclerostin concentrations; whether the same applies to HBM due to other causes is unknown. Objective: To determine circulating sclerostin concentrations in HBM. Design: Case-control study Participants: 406 HBM index cases were identified by screening DXA databases from 4 UK centers (n=219,088), excluding significant osteoarthritis/artefact. Controls comprised unaffected relatives & spouses. Main measure(s): Plasma sclerostin, lumbar spine L1, total hip and total body DXA, and radial and tibial pQCT (subgroup only). Results: Sclerostin concentrations were significantly higher in both LRP5 HBM and non-LRP5 HBM cases, compared with controls; mean[SD] 130.1[61.7] and 88.0[39.3], vs. 66.4[32.3]pmol/L, both p
