Alternative titles and symbols : Osteogenesis imperfecta with normal sclerae; Oi, type iv;
Description : Osteogenesis imperfecta (OI) is a connective tissue disorder that is caused by an
abnormality of type I collagen in over 90% of cases. Due to considerable phenotypic
variability, Sillence et al. (1979) developed a classification of OI subtypes: OI
type I with blue sclerae (166200); perinatal lethal OI type II, also known as congenital
OI (166210); OI type III, a progressively deforming form with normal sclera (259420);
and OI type IV, with normal sclerae. Levin et al. (1978) suggested that OI subtypes
could be further divided into types A and B based on the absence or presence of dentinogenesis
imperfecta.;
Inheritance : Autosomal dominant;
Molecular basis : Caused by mutation in the collagen I, alpha-1 polypeptide gene (COL1A1, 120150.0003); Caused by mutation in the collagen I, alpha-2 polypeptide gene (COL1A2, 120160.0004);
