LRP5 and osteoporosis: Interestingly, two LRP5 HBM cases (p.Arg266Cys; p.Asn198Ser) still had high BMD despite long‐term glucocorticoid use; whether anabolic LRP5 mutations confer a relative resistance to glucocorticoid‐induced osteoporosis remains to be determined, but if so, it would be of great pharmacotherapeutic interest.
