A tripeptide deletion in the triple-helical domain of the pro alpha 1(I) chain of type I procollagen in a patient with lethal osteogenesis imperfecta does not alter cleavage of the molecule by N-proteinase.

Abstract excerpt

Dermal fibroblasts from a fetus with perinatal lethal osteogenesis imperfecta synthesized normal and abnormal type I procollagen molecules. The abnormal molecules contained one or two pro alpha 1(I) chains in which glycine, alanine, and hydroxyproline at positions 874, 875, and 876 in the triple-helical region were deleted as the result of a 9-base pair genomic deletion. Molecules that contained abnormal chains...
