A lethal variant of osteogenesis imperfecta has a single base mutation that substitutes cysteine for glycine 904 of the alpha 1(I) chain of type I procollagen. The asymptomatic mother has an unidentified mutation producing an overmodified and unstable type I procollagen.
A fraction of the pro alpha 1(I) and pro alpha 2(I) chains in type I procollagen synthesized by the fibroblasts from a proband with a lethal variant of osteogenesis imperfecta were overmodified by posttranslational reactions. After digestion with pepsin, some of the alpha 1(I) chains were recovered...
