Abstract excerpt
INTRODUCTION: Increased bone fragility in osteogenesis imperfecta (OI) is not totally accounted for by decreased bone mineral density (BMD), and alterations of type I collagen (Col I) are believed to play a role. Newly synthesized Col I comprises non isomerized C-telopeptide (alphaCTX), but with bone matrix maturation alphaCTX is converted to its isomerized beta form (betaCTX). Urinary alpha/betaCTX ratio has...
