Postmenopausal osteoporotic fracture-associated COLIA1 variant impacts bone accretion in girls.

ABSTRACT: Over the past two decades, a low frequency variant (rs1800012) within the first intron of the type I collagen alpha 1 (COLIA1) gene has been implicated in lower areal BMD (aBMD) and increased risk of osteoporotic fracture. This association is particularly strong in postmenopausal women, in whom net bone loss arises in the context of high bone turnover. High bone turnover also accompanies childhood linear growth; however, the role of rs1800012 in this stage of net bone accretion is less well understood. Thus, we assessed the association between rs1800012 and aBMD and bone mineral content (BMC) Z-scores for the 1/3 distal radius, lumbar spine, total hip, and femoral neck total body less head in the Bone Mineral Density in Childhood Study, a mixed-longitudinal cohort of children and adolescen
