Osteogenesis imperfecta.

Our clinical files on osteogenesis imperfecta are brought up-to-date reviewing a total of 33,555 cases admitted between 4/XII/48 and 31/VIII/76. From these, 5 clinical cases were found. The extreme rareness of this regional pathology in our Cátedra y Sericio de Pediatría, which is the largest concentration center in Paraguay had led us to make this publication. From our casuistics, we may singl...

Lethal osteogenesis imperfecta.

Perinatal lethal osteogenesis imperfecta.

Perinatal lethal osteogenesis imperfecta is the result of heterozygous mutations of the COL1A1 and COL1A2 genes that encode the alpha 1(I) and alpha 2(I) chains of type I collagen, respectively. Point mutations resulting in the substitution of Gly residues in Gly-X-Y amino acid triplets of the triple helical domain of the alpha 1(I) or alpha 2(I) chains are the most frequent mutations. They int...

Current and emerging treatments for the management of osteogenesis imperfecta

Osteogenesis imperfecta (OI) is the most common bone genetic disorder and it is characterized by bone brittleness and various degrees of growth disorder.
