Osteogenesis imperfecta is a group of genetic disorders, all of which cause bone fragility. OI has high genetic heterogeneity , that is, many different genetic mutations lead to the same or similar sets of observable symptoms ( phenotypes ).
A triangular face, in the simplest sense, is a human face shape with a lower half that becomes relatively thin, approaching an appearance of a triangle with a tip facing downwards. It is not necessarily caused by any disease, but is common in individuals with Osteogenesis Imperfecta. [1]
These alterations negatively affect tissues that are rich in type I collagen, such as the skin, bones, teeth, and tendons, leading to the signs and symptoms of type III osteogenesis imperfecta. Osteogenesis imperfecta, type IV : Several different types of mutations in the COL1A1 gene cause osteogenesis imperfecta type IV.
The body-positive movement has encouraged people, especially women, to see beauty in all shapes and sizes, and it's reminded us that body ideals are culturally constructed and not based on science.
Figures in film, television, video games and novels depicted as having osteogenesis imperfecta include: Samuel L. Jackson's character Elijah Price in M. Night Shyamalan's 2000 film Unbreakable and its 2019 follow-up Glass, who was born with type I osteogenesis imperfecta and who adopts his childhood nickname "Mr. Glass" as a villain identity. [62]
Ossification (also called osteogenesis or bone mineralization) in bone remodeling is the process of laying down new bone material by cells named osteoblasts. It is synonymous with bone tissue formation. [ 1 ]
In classic non-deforming osteogenesis imperfecta with blue sclerae or common variable osteogenesis imperfecta with normal sclerae, nearly 60% of cases are de novo. COL1A1/2-related osteogenesis imperfecta is identified by repeated fractures with trivial trauma, defective dentinogenesis imperfecta (DI), and hearing loss.
Type I collagen is the most abundant collagen of the human body, consisting of around 90% of the body's total collagen in vertebrates. Due to this, it is also the most abundant protein type found in all vertebrates. Type I forms large, eosinophilic fibers known as collagen fibers, which make up most of the rope-like dense connective tissue in ...
