Abstract excerpt
Cultured fibroblasts from a patient affected with a moderate form of osteogenesis imperfecta were defective for the synthesis of type I collagen molecules; about half of the alpha 1(I) chains contained a cysteine residue in the triple helical domain and a disulfide link formed when two mutant alpha 1(I) chains were incorporated into a type I collagen heterotrimer. The proband's parents were clinically and...
