Does the Skeletal Phenotype of Osteogenesis Imperfecta Differ for Patients With Non-COL1A1/2 Mutations? A Retrospective Study in 113 Patients.

Abstract excerpt

BACKGROUND: Osteogenesis imperfecta (OI) is a heritable disease characterized by bone fragility and other extra skeletal manifestations. Most patients with OI have mutations in the COL1A1 or COL1A2 genes. However, a significant minority of patients with clinical OI have non-COL1A1/2 mutations, which have become easier to detect with the use of genetic panels. Traditional understanding of OI pathogenesis was...
