  • Osteogenesis imperfecta 14 (OI14) [MIM:615066]: An autosomal recessive form of osteogenesis imperfecta, a connective tissue disorder characterized by low bone mass, bone fragility and susceptibility to fractures after minimal trauma. Disease severity ranges from very mild forms without fractures to intrauterine fractures and perinatal lethality. Extraskeletal manifestations, which affect a variable number of patients, are dentinogenesis imperfecta, hearing loss, and blue sclerae. OI14 is 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. {ECO:0000269 PubMed:23054245, ECO:0000269 PubMed:23316006}. Note=The disease is caused by mutations affecting the gene represented in this entry.
