Influence of bone age and allelic variants of the vitamin D receptor (VDR) gene on bone mass indices in adolescent boys

The aim of this study was to evaluate the influence of bone age and FokI polymorphism on bone mass indices in healthy adolescent boys (11–14y, n=47). Bone age was assessed by left hand x‐ray. Total body bone mineral density (TBMD) and content (TBMC) were assessed by DXA. Plasma testosterone and serum PTH were measured by radioimuno‐ and chemiluminescent assay – respectively. VDR genotypes were determined by PCR amplification and enzymatic digestion of the products with FokI.
