However, he died unexpectedly at 6 weeks of age with the cause of death being attributed to suddeninfantdeathsyndrome (SIDS). Necropsy showed abnormal rib morphology with anterior flaring and evidence of a healing left femoral fracture.[jmg.bmj.com]

The Child will be shorter or of less than average height for their age, with shorthumerus and femur. The child will have a fracture when learning to walk.[news-medical.net]
Shorthumerus (arm bone) and short femur (upper leg bone) Coxa vera is common (the acutely angled femur head affects the hip socket). Results from recessive inheritance of a mutation to the CRTAP (cartilage-associated protein) gene.[oif.org]
In some cases, individuals with OI type I may develop abnormalities affecting the middle and/or inner ears contributing to, or resulting in, hearingimpairment (i.e., conductive and/or sensorineural hearing loss).[rarediseases.org]

Treatment Currently, there is no known cure for osteogenesis imperfecta. The primary focus of treatment is on preventing injuries and maintaining healthy bones.[verywell.com]
The affected child received further treatment initially stationary, later as an ambulant patient.[degruyter.com]
Treatment There is no cure for brittle bone disease, but treatment can relieve symptoms, prevent breakage of bones, and maximize movement.[webmd.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]
The parents opted to interrupt the pregnancy, based on the diagnosis of a lethal skeletal dysplasia and the associated poor prognosis. The fetus was delivered at 25 weeks’ gestation.[sajr.org.za]
Prognosis - Osteogenesis imperfecta- type 6 The prognosis for an individual with OI varies greatly depending on the number and severity of symptoms.[checkorphan.org]
Etiology OI type IIA is caused by mutations of the COL1A1 and COL1A2 genes (17q21.31-q22 and 7q22.1 respectively) and transmission is autosomal dominant.[orpha.net]
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]
Summary Epidemiology The overall prevalence of OI is estimated at between 1/10,000 and 1/20,000 but the prevalence of type II is unknown.[orpha.net]

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]
Pathophysiology OI is the result of mutations affecting the synthesis and processing of type I collagen, the major protein in bone and connective tissue.[clinicaladvisor.com]
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]
Surgery may be performed to correct and prevent deformities in children with OI severe enough to prevent walking. Correction of scoliosis may also be helpful, but difficult due to bone fragility.[myvmc.com]
Broken bones in children with osteogenesis imperfecta are often treated with surgery in order to stabilize the bones and prevent deformities.[verywell.com]
