Osteogenesis imperfecta (OI) - COL1A1 - Golden Retriever

Osteogenesis imperfecta (OI) - Golden Retriever is a hereditary disease which can be tested with a DNA test. Osteogenesis imperfecta (OI) is a hereditary disease characterized by extremely fragile bones and teeth. Clinical signs include pain, spontaneous fractures of bones and teeth fractures, joint hyperlaxity and reduced bone density on radiography. Teeth are very thin and fragile, otherwise normal size. In affected dogs, clinical signs occur within the first few weeks of life. OI is characterized by significant reduction of the formation of bone and tooth mass (osteopenia and dentinopenia) due to a defect in the formation of collagen type I. Collagen type I represents 90% of the organic material of bones, tendons and teeth. While it gives structure and elasticity to these organs, the defects in collagen lead to fragility. Osteogenesis imperfecta can range from mild to severe and symptoms vary from one dog to another.
