Our finding that DM was associated with higher sclerostin levels likely reflected an association with T2DM, which comprised DM cases in LURIC, and presumably explains the great majority of ALSPAC cases (although ascertainment of DM in ALSPAC was based on use of anti‐diabetic medication, which would have included those with T1DM, 90% of UK adults with DM have T2DM(37)). The gene discussed is SOST; the disease is diabetes mellitus.
