An osteopenic nonfracture syndrome with features of mild osteogenesis imperfecta associated with the substitution of a cysteine for glycine at triple helix position 43 in the pro alpha 1(I) chain of type I collagen.
Mild dominant osteogenesis imperfecta with intrafamilial variability: the cause is a serine for glycine alpha 1(I) 901 substitution in a type-I collagen gene.
The substitution of arginine for glycine 85 of the alpha 1(I) procollagen chain results in mild osteogenesis imperfecta. The mutation provides direct evidence for three discrete domains of cooperative melting of intact type I collagen.
Osteogenesis imperfecta. The position of substitution for glycine by cysteine in the triple helical domain of the pro alpha 1(I) chains of type I collagen determines the clinical phenotype.
A cysteine for glycine substitution at position 1017 in an alpha 1(I) chain of type I collagen in a patient with mild dominantly inherited osteogenesis imperfecta.
