- Abstract
A substitution of arginine for glycine at amino acid position 154 of the alpha 1(I) collagen chain was found in a father and his three children. The phenotype of the patients includes manifestations of types I and III/IV osteogenesis imperfecta, but appears to be milder than that of the previously described two unrelated patients that had the identical mutation in the alpha 1(I) collagen chain. The variability in the phenotype raises the possibility of epistatic loci or environmental effects on expression of the disorder.
