Osteogenesis Imperfecta Inheritance Pattern - Web osteogenesis imperfecta means “imperfect bone formation” and is commonly known as “brittle bone disease” or oi. Osteogenesis imperfecta (oi, or brittle bone disease) is a clinically and genetically heterogeneous group of heritable disorders of connective tissue. Collagen amount is 50% reduced; Web the inheritance pattern is autosomal dominant. Web updated july 26, 2020. Oi is also known as brittle bone disease, and the symptoms can range from mild with only a few fractures to severe with many medical complications. Osteogenesis imperfecta type 1 is the mildest form of oi and is characterized by bone fractures during childhood and adolescence that often result from minor trauma. Types vi through xi are autosomal recessive. Web oi patients were classified in four syndromes by primary clinical characteristics and pattern of inheritance namely (i) dominantly inherited oi with blue sclerae, (ii) lethal perinatal oi with radiographically crumpled femora and beaded ribs, (iii) progressively deforming oi, and (iv) dominantly inherited oi with normal sclerae. It is a rare genetic disorder that affects the protein collagen, which is found in bone, teeth, skin, tendons, and parts of the eye.

Web when caused by mutations in the col1a1 or col1a2 gene, osteogenesis imperfecta has an autosomal dominant pattern of inheritance, which means one copy of the altered gene in each cell is sufficient to cause the condition. About 60% of people diagnosed with oi each year inherited oi from a parent and the condition is described as dominantly inherited. Web signs and symptoms may range from mild to severe. Autosomal recessive inheritance means two copies of the gene in each cell are altered.

Oi is also known as brittle bone disease, and the symptoms can range from mild with only a few fractures to severe with many medical complications. Genetic mutations can be hereditary, when parents pass them down to their children, or they may occur randomly when cells are dividing. At our institution during the past 15 years (unpublished data).
