Cultured skin fibroblasts from a proband with a lethal form of osteogenesis imperfecta produce two forms of type I collagen chains, with normal and delayed electrophoretic migration; collagen of the proband's mother was normal. Peptide mapping experiments localized the structural defect in the proband to alpha1(I) CB8 peptide in which residues 123 to 402 are spaned. Direct sequencing of amplified cDNA covering this region revealed a G to A single base change in one allele of the alpha1(I) chain, that converted glycine 388 to arginine. Restriction enzyme digestion of the RT-PCR product was consistent with a heterozygous COL1A1 mutation. The novel mutation conforms to the linear gradient of clinical severity for the alpha1(I) chain and results in reduced thermal stability by 3 degrees C and intracellular retention of abnormal molecules.

AbstractOsteogenesis imperfecta (OI) is a rare heritable bone disorder characterized by low bone mineral density (BMD), recurrent bone fractures, and progressive bone deformities. P4HB encodes protein disulfide isomerase (PDI) and is identified as a novel candidate gene of OI. The purposes of the present study are to detect pathogenic mutation, to evaluate the phenotypes of a Chinese family with mild OI, and to investigate the effects of bisphosphonates on bone of the proband. We detected the pathogenic mutation by next generation sequencing and Sanger sequencing. Laboratory and radiological investigations were conducted to evaluate the phenotypes. The proband was a 12-year-old girl with low BMD, history of recurrent non-traumatic fractures, slight scoliosis, with bluish grey sclera and ligamentous laxity. Her father suffered from one fragility fracture and slight wedge changes of vertebras, with bluish grey sclera. We identified a novel heterozygous missense mutation (c.692A>C, p.His231Pro) in P4HB in the proband and her father. This mutation was predicted to affect the combination of PDI with type I procollagen and lead to the disorder of its triple helix formation. Bisphosphonates were effective in reducing bone resorption and increasing BMD of the proband with well tolerance. In conclusion, we identified a novel mutation in P4HB in a Chinese family with mild OI, which expanded the genotypic and phenotypic spectrum of OI. Bisphosphonates were effective to this extremely rare OI induced by P4HB mutation.
