Presentation
He is Executive Advisory Editor of Bone Research (2013-present). [books.google.com]
In addition to this some key clinical observations may be present such as: Blue Sclerae (whites of the eyes) – this is a characteristic feature of OI Type 1 but is not present in all forms of OI. [oiaustralia.org.au]
The mild form results in fractures, whereas the severe form presents more like a syndrome constituting a pattern of disorders. [lecturio.com]
PRESENTATION OF OSTEOGENESIS IMPERFECTA The presentation of disease varies widely across patient populations. It often varies in severity as you move from type I (mild) to type IV (severe). [gwumc.edu]
The severity of the clinical presentation depends upon the effect of the mutation ( table 1 and table 2 ) [ 3-7 ]. [uptodate.com]
Entire Body System
- Short Stature
OI15 is characterized by early-onset recurrent fractures, bone deformity, significant reduction of bone density, short stature, and, in some patients, blue sclerae. Tooth development and hearing are normal. [malacards.org]
Silence type I to IV Type-I: 70% of total case, bone density reduced 60% of normal, mild short stature & variable bone fragility. [slideshare.net]
All of these children had short stature, low bone density, and severe vertebral compression fractures in addition to multiple long bone fractures in the first years of life. [jmg.bmj.com]
- Vietnamese
The populations include African Americans, Vietnamese, Burmese, Samoan and First Nation Canadians. [uwcpdx.org]

Eyes
- Blue Sclera
Extraskeletal manifestations, which affect a variable number of patients, are dentinogenesis imperfecta, hearing loss, and blue sclerae. [malacards.org]
sclerae which remain intensely blue throughout life, in contrast to the sclerae in OI type III and OI type IV which may also be blue at birth and during infancy. [edoj.org.eg]
The four OI types are now referred to as follows: OI type I: classic non-deforming OI with blue sclerae. OI type II: perinatally lethal OI. OI type III: progressively deforming OI. OI type IV: common variable OI with normal sclerae. [ncbi.nlm.nih.gov]

Prognosis
The management and prognosis of OI are discussed separately. (See "Osteogenesis imperfecta: Management and prognosis" .) EPIDEMIOLOGY The estimated incidence of OI is approximately 1 per 20,000 births [ 1 ]. [uptodate.com]
Prognosis: The prognosis often depends on the type of OI and thus the severity of the disease. Type I patients often have a normal life expectancy. [gwumc.edu]
This classification system can be helpful in providing information about prognosis and management for a given individual. The four OI types are now referred to as follows: OI type I: classic non-deforming OI with blue sclerae. [ncbi.nlm.nih.gov]
Prognosis is very variable depending on type ranging from being uniformly lethal from type II to a slight reduction in life expectancy for type I. [radiopaedia.org]

Etiology
Etiology OI type III can be autosomal dominant and caused by mutations of the COL1A1 and COL1A2 genes (17q21.31-q22 and 7q22.1 respectively), or it can be autosomal recessive and caused by mutations of the CRTAP gene (3p22) (sometimes described as OI [orpha.net]
Etiology of Osteogenesis Imperfecta Osteogenesis Imperfecta is an inherited disorder that runs in the family. Spontaneous mutations can also occur at the time of conception. [lecturio.com]
Osteoporosis is a chronic condition of multifactorial etiology and is usually clinically silent until a fracture occurs. [ghr.nlm.nih.gov]
However, these disorders, while clinically sharing some features of true OI, are better designated as separate conditions based on their unique molecular etiologies. Treatment Treatment Options: Avoidance of trauma is paramount. [disorders.eyes.arizona.edu]
With regards to an etiological diagnosis, collagen analysis and genetic testing is advantageous, but not always necessary. [spandidos-publications.com]
Epidemiology
Summary Epidemiology The overall prevalence of OI is estimated at between 1/10,000 and 1/20,000 but the prevalence of type III is unknown. [orpha.net]
EPIDEMIOLOGY The estimated incidence of OI is approximately 1 per 20,000 births [ 1 ]. This qualifies it as an orphan disease, which is defined in the United States as a disease affecting 200,000 patients or less. [uptodate.com]
EPIDEMIOLOGY AND PREVALENCE Osteogenesis Imperfecta occurs in approximately 1 in 20,000 live births. More than 200 gene mutations have been associated with the OI phenotype. [gwumc.edu]
Epidemiology of Scoliosis in Children It can occur on the left or right side or both sides of the different spine sections. [lecturio.com]
Pathophysiology
However, in the past 10 years discoveries of further (mainly recessive) causative genes have lent support to a predominantly collagen-related pathophysiology [ 1 ]. [patient.info]
This classification scheme is likely to change with additional research on pathophysiology of OI. [nature.com]
A multidisciplinary approach is required to manage the disease. [1, 2, 3] Pathophysiology In OI, pathologic changes are seen in all tissues of which type 1 collagen is an important constituent (eg, bone, ligament, dentin, and sclera). [emedicine.medscape.com]

Prevention
His research in musculoskeletal biology covers topics such as glucocorticoid signalling in bone and its effects on bone and systemic fuel metabolism and ageing; the biology of bone metastases; and the clinical efficacy of secondary fracture prevention [books.google.com]
This is done to strengthen them and to correct and prevent deformities. This surgery is usually only performed on children when OI is severe enough to prevent walking. [clevelandclinic.org]
Rodding is also done to stabilize long bones and to prevent fractures. [lecturio.com]
Prevention As a congenital birth defect, OI cannot be prevented. Individuals at risk of having a child with OI should be encouraged to undergo genetic counseling to more accurately determine their chances of having a child with OI. [healthofchildren.com]
Prompt reduction of fractures is important to the prevention of deformities. A multidisciplinary team is important for the treatment and rehabilitation of patients. References References Byers PH, Pyott SM. [disorders.eyes.arizona.edu]
