title: Altered processing of alpha (I) collagen in a case of lethal osteogenesis imperfecta.
abstract: Cultured skin fibroblasts from a newborn with the lethal perinatal form of Osteogenesis imperfecta synthesized an over-hydroxylated form of pro alpha 1 (I) chain. The analysis of the CNBr peptides showed that over-hydroxylation occurred all along the molecule.
