Osteogenesis imperfecta type 14

Synonyms
OI, TYPE XIV; Osteogenesis imperfecta, type xiv

Summary

Osteogenesis imperfecta (OI) is a connective tissue disorder characterized by bone fragility and low bone mass. Due to considerable phenotypic variability, Sillence et al. (1979) developed a classification of OI subtypes based on clinical features and disease severity: 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 sclerae (259420); and OI type IV, with normal sclerae (166220). Most cases of OI are autosomal dominant with mutations in 1 of the 2 genes that code for type I collagen alpha chains, COL1A1 (120150) and COL1A2 (120160). Shaheen et al. (2012) described osteogenesis imperfecta type XIV (OI14), an autosomal recessive form of the disorder characterized by variable degrees of severity of multiple fractures and osteopenia, with normal teeth, sclerae, and hearing. Fractures first occur prenatally or by age 6 years. [from OMIM]
