Osteogenesis imperfecta research paper

The major collagen of skin, tendon, and bone is the same protein containing 2 alpha-1 polypeptide chains and 1 alpha-2 chain.

Although these are long the procollagen chain has a molecular mass of about kD, before the 'registration peptide' is cleaved off; seeeach messenger RNA is monocistronic Lazarides and Lukens, Differences in the collagens from these 3 tissues are a function of the degree of hydroxylation of proline and lysine residues, aldehyde formation for cross-linking, and glycosylation.

The alpha-1 chain of the collagen of cartilage and that of the collagen of basement membrane are determined by different structural genes.

The collagen of cartilage contains only 1 type of polypeptide chain, alpha-1, and this is determined by a distinct locus. The fetus contains collagen of distinctive structure. The genes for types I, II, and III collagens, the interstitial collagens, exhibit an unusual and characteristic structure of a large number of relatively small exons 54 and bp at evolutionarily conserved positions along the length of the triple-helical gly-X-Y portion Boedtker et al.

The family of collagen proteins consists of a minimum of 9 types of collagen molecules whose constituent chains are encoded by a minimum of 17 genes Ninomiya and Olsen, Solomon and Sykes concluded, incorrectly as it turned out, that both the alpha-1 and the alpha-2 genes of collagen I are on chromosome 7.

Solomon and Sykes also presented evidence that the alpha-1 chains of collagen III are also coded by chromosome 7. Because they had previously assigned a gene for skin type I procollagen to chromosome 17, they wondered whether skin and corneal type I collagen may be under separate control.

In situ hybridization using the same probe indicated that the gene is in the middle third of the long arm, probably in band 17q21 or 17q By chromosome-mediated gene transfer CMGTKlobutcher and Ruddle transferred the genes for thymidine kinase, galactokinaseand type I procollagen gene for alpha-1 polypeptide.

The data indicated the following gene order: By in situ hybridization, Retief et al.Osteogenesis imperfecta (OI), also known as brittle bone disease, is a rare genetic disorder with the main characteristic being that the bones break very easily, usually for no apparent reason.

Osteogenesis imperfecta is a genetic condition characterized by bone fragility and recurrent fractures, which in the large majority of patients are caused by defects in the production of type I collagen.
