Type : Phenotype, molecular basis known;
Alternative titles and symbols : Osteogenesis imperfecta congenita, perinatal lethal form; Osteogenesis imperfecta congenita; Oi, type II; Vrolik type of osteogenesis imperfecta; OIC;
Description : Osteogenesis imperfecta type II constitutes a disorder characterized by bone fragility,
with many perinatal fractures, severe bowing of long bones, undermineralization, and
death in the perinatal period due to respiratory insufficiency (Sillence et al., 1979;
Barnes et al., 2006). Also see osteogenesis imperfecta type VII (610682), an autosomal
recessive form of lethal OI caused by mutation in the CRTAP gene (605497).;
Inheritance : Autosomal dominant;
Molecular basis : Caused by mutation in the collagen I, alpha-1 polypeptide gene (COL1A1, 120150.0001); Caused by mutation in the collagen I, alpha-2 polypeptide gene (COL1A2, 120160.0007);
