The clinical severity of OI can vary greatly, even within families who share a common mutation . Summary. The baby was diagnosed to have Osteogenesis Imperfecta type II with birth asphyxia. osteogenesis imperfecta caused by mutation in COL1A2 gene and unstable collagen type I. Fractures occur less frequently in adulthood. Osteogenesis imperfecta (OI) is an inherited connective tissue disorder with many phenotypic presentations. OI may be suspected because of the presence of symptoms that are common to OI along with a family history of fractures or symptoms of OI. The goals of treatment are to: Prevent or control symptoms. Approximately 85% of OI cases are caused by dominant autosomal mutations in the type I collagen coding genes (COL1A1 and COL1A2), which affect the quantity or structure of collagen.The remaining percentage of cases is caused by mutation in the proteins responsible for . It is often caused by a defect in the gene that produces type 1 collagen, an important building block of bone. Treatment options Osteogenesis many diseases through a combination of ex vivo genetic imperfecta treatment is typically focused on preventing or manipulation and autologous transplantation. The treatment mainly aims at providing symptomatic relief. Typical problems seen in patients who have osteogenesis imperfecta include bone fragility, short stature, scoliosis, tooth defects, hearing deficits, bluish sclera, and loose ligaments. In severe forms, a person with OI may have hundreds of broken bones, even before birth. The diagnosis of osteogenesis imperfecta usually depends on family history and clinical presentation characterized by a fracture (or fractures) during the prenatal period, at birth or in early childhood; genetic tests can confirm diagnosis. In the past 10 years, defects in at least 17 other genes have been identified as responsible for osteogenesis imperfecta phenotypes, with either dominant or recessive transmission. Diagnosis. There are many defects that can affect this gene. A doctor may suspect a diagnosis of osteogenesis imperfecta (OI) because of the presence of certain symptoms, especially repeated fractures that occur without trauma or only mild trauma. 2 AMS Circle Bethesda, MD 20892-3676 Phone: 202-223-0344 . Treatments for preventing or correcting symptoms may include: Care of fractures. If you have 1 copy of the gene, you will have the disease. Osteogenesis imperfecta, also called brittle bone disease, is a genetic disorder that causes bones to fracture or break easily, often without obvious cause. OI is predominantly caused by dominant mutations affecting type 1 collagen synthesis, with a number of other genes implicated in OI over recent years. This diagnosis was reached because of the presence of the multiple fractures at birth, the blue-grey coloration of sclera, micromelia, and osteopenia (Edelu et al.

OI varies in severity from person to person, ranging from a mild type to a severe type that causes death before or shortly after birth. | NICHD - Eunice Kennedy Shriver National Institute of Child Health and Human Development Osteogenesis imperfecta (OI) is a group of genetic disorders that mainly affect the bones.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. Shriners Children's closely evaluates each and every patient to formulate a treatment plan for their particular needs. Brittle bone disease, or Osteogenesis Imperfecta (OI), is a genetic bone disorder characterised by easily breakable fragile bones.It is a rare condition and is currently estimated that one in every 15,000 people are born with OI, equating to around 5,000 individuals in the UK. Osteogenesis imperfecta (OI), a heritable disorder of connective tissue, is characterized by brittle bones, blue sclera, dentinogenesis imperfecta, adult onset deafness and short stature. There is no cure for OI. The collagen genes play a role in how the body makes collagen, a material that helps to strengthen the bones. Medical treatment consists of bisphosphonate use, even in patients younger than age 2 years. OI treatments are designed to prevent or control symptoms and may include fracture care, physical therapy, bracing, surgery, and medication. The genetic disorder in most cases is passed from one of the parents to the child through autosomal dominant inheritance.This means that one copy of the mutated gene in each cell is enough to cause the osteogenesis imperfecta. Osteogenesis imperfecta (OI), commonly known as brittle bone disease, is a hereditary connective tissue disease characterized by fragile bones that are highly prone to breaking. : 85 The range of symptoms—on the skeleton as well as on the body's other organs—may be mild to severe. Bisphosphonate treatment decreases long-bone fracture rates, but such fractures are still frequent. Treatment includes growth hormone for some types and bisphosphonates. Osteogenesis imperfecta continues to be the paradigm for understanding the molecular basis of heritable connective tissues and evaluating therapeutic strategies for disorders affecting the mineralized skeleton.
