RT Journal Article SR Electronic A1 Parry, Nicola T1 What's New in Osteogenesis Imperfecta? JF MD Conference Express YR 2013 FD SAGE Publications VO 13 IS 10 SP 23 OP 24 DO 10.1177/155989771310011 UL http://mdc.sagepub.com/content/13/10/23.abstract AB This article discusses the pathophysiology of osteogenesis imperfecta (OI), in particular in relation to some rare, recessive forms of the condition. Although historically considered a collagen-related condition, predominantly due to mutations in genes that encode the alpha chains of collagen type I, mutations in various noncollagenous genes have also more recently been discovered to cause some forms of OI.
