Osteogenesis imperfecta (OI) is a genetic bone fragility disorder characterized by low bone mass, skeletal deformity, and variable short stature. OI is predominantly caused by dominant mutations affecting type 1 collagen synthesis, with a number of other genes implicated in OI over recent years Osteogenesis imperfecta (OI), an inherited skeletal disorder characterized by low bone mass, bone fragility, and often short stature. The clinical severity varies widely from being nearly asymptomatic with a mild predisposition to fractures, normal stature and normal lifespan being to profoundly disabling and even lethal Osteogenesis imperfecta (OI) is a rare congenital disease with a wide spectrum of severity characterized by skeletal deformity and increased bone fragility as well as additional, variable extraskeletal symptoms Osteogenesis imperfecta, also known as brittle bone disease, is a group of genetic disorders that mainly affect the bones. It results in bones that break easily. The severity may be mild to severe. Other symptoms may include a blue tinge to the whites of the eye, short height, loose joints, hearing loss, breathing problems and problems with the teeth. Complications may include cervical artery dissection and aortic dissection. The underlying mechanism is usually a problem with.

Severely affected patients suffer multiple fractures with minimal or no trauma, and infants with the worst form of OI die in the perinatal period Introduction. The identification of the first gene for recessive osteogenesis imperfecta in 20061, 2 initiated a burst of exciting new information about the genetics and mechanism of this bone dysplasia. 3 Osteogenesis imperfecta, or brittle bone disease, is a fairly common rare disorder (one in 15-20 000 births). This generalised connective tissue disorder has major manifestations in bone. Osteogenesis imperfecta, also known as brittle bone disease, is a genetic disorder that causes bones to break easily without cause. The condition affects the body's ability to produce collagen, a protein in the body's connective tissue. There are four types of osteogenesis imperfecta, which vary greatly in how severe they are. Type I is the most common and mildest form

The 2 conditions are associated with similar symptoms due to overlapping mutations of COL1A1, the gene that encodes type I collagen Osteogenesis imperfecta now have additional genes that cause brittle bones and is slowly spreading across generations and countries. It is also known as brittle bone disease, Lobstein syndrome, fragilitas ossium, Vrolik disease. Osteogenesis imperfecta is characterized by bones that break easily often from little or no apparent cause Osteogenesis imperfecta is a rare hereditary disease mostly caused by mutations impairing collagen synthesis and modification. Recently recessive forms have been described influencing differentiation and activity of osteoblasts and osteoclasts. Most prominent signs are fractures due to low traumata and deformities of long bones and vertebrae Osteogenesis imperfecta (OI) is a genetic disorder of connective tissues caused by an abnormality in the synthesis or processing of type I collagen.

Osteogenesis imperfecta (OI) is a genetic disorder in which bones break easily. Sometimes the bones break for no known reason. OI can also cause weak muscles, brittle teeth, a curved spine and hearing loss. Osteogenesis imperfecta develops due to a genetic mutation in the gene that directs the body to produce collagen Osteogenesis imperfecta (also known as brittle bone disease or OI) is a genetic condition that causes a defect in a protein found in bones—called collagen. The defect leads to fragile bones that can break easily. It is a lifelong condition that varies greatly in severity, affecting bone quality and bone mass Osteogenesis imperfecta is described as a rare disorder occurring in approximately 1 per 10,000 live births. Most physicians do not treat individuals with OI, and this may present problems when diagnostic or treatment decisions are required

Osteogenesis imperfecta (OI), also known as brittle bone disease, is a phenotypically diverse disorder due to deficiencies in the synthesis of type I collagen [ 1 ]. OI is a disease characterized by brittle bones and frequent fractures with minimal trauma leading to skeletal deformities [ 2 ] Osteogenesis imperfecta (OI) is an inherited skeletal dysplasia characterized by bone fragility and skeletal deformities. While the majority of cases are associated with pathogenic variants in COL1A1 and COL1A2, the genes encoding type I collagen, up to 25% of cases are associated with other genes that function within the collagen biosynthesis pathway or are involved in osteoblast.

Osteogenesis imperfecta affects males and females in equal numbers. The exact number of individuals with OI in the United States (prevalence) is unknown. OI type I is estimated to occur in one in 30,000 live births. OI type II is estimated to occur in one in 60,000 live births IV osteogenesis imperfecta might be slightly lower than that for the general population (8). The main features of each type of osteogenesis imperfecta are summarized in the Table (9,10). The remainder of the article describes the cra-nial, craniospinal junction, and spinal manifesta Osteogenesis imperfecta (OI), also known as brittle bone disease, is a group of genetic disorders that mainly affect the bones.

Osteogenesis Imperfecta results from mutations in either of the two genes coding for type 1 collagen, COL1A1 or COL1A2. While over 250 different mutations have been identified causing OI, the two most common types are: Null mutations in which the mutated protein is not incorporated into the type 1 collagen usually lead to milder forms of the. Some patients with osteogenesis imperfecta experience ligamentous laxity, joint hyperflexibility, and dental abnormalities. The annual incidence of osteogenesis imperfecta in the United States and Canada is one in 10,000 to 20,000 births (4,5) 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 (); perinatal lethal OI type II, also known as congenital OI (); OI type III, a progressively. Osteogenesis imperfecta can also cause weak muscles, brittle teeth, a curved spine, and hearing loss. Osteogenesis imperfecta is caused by one of several genes (COL1A1, COL1A2, CRTAP, and P3H1 genes) that aren't working properly. When these genes don't work, it affects how you make collagen, a protein that helps make bones strong

Osteogenesis imperfecta is a congenital bone disorder characterized by brittle bones that are prone to fracture. Osteogenesis imperfecta may present with shorter height, neurological features including communicating hydrocephalus, basilar invagination, and seizures, blue sclerae, hearing loss, and other complications.Associated fractures may cause acute or chronic pain, reduced quality of life.

Osteogenesis imperfecta is a genetic disorder of increased bone fragility, low bone mass, and other connective-tissue manifestations. The most frequently used classification outlines four clinical types, which we have expanded to seven distinct types. In most patients the disorder is caused by mutations in one of the two genes encoding collagen type 1, but in some individuals no such mutations. Osteogenesis imperfecta (OI) is a disorder of bone fragility chiefly caused by mutations in the COL1A1 and COL1A2 genes that encode type I procollagen.Four types of osteogenesis imperfecta were originally described by Sillence in 1979 and are now used broadly as the Sillence criteria.
