What Causes OI?<br />Caused by a defect in the gene that produces collagen in the bone<br />Specific gene defected will cause severity to the OI patient<br />
Transmission<br />Can be transmitted through DNA from parent to child<br />Also can be developed by a new genetic mutation<br />Not contagious/communicable<br />
Who Can Get It?<br />OI will develop only as an infant<br />May be detected at a later age<br />Anyone that carries the gene is more susceptible to having the disease <br />
Signs and Symptoms<br />People with OI will have it for life<br />Weak bones prone to accidents<br />Blue tints to the whites of their eyes<br />Many bone fractures from minimal force<br />Early hearing loss<br />Below average height for age<br />Bowed arms or legs (in most severe cases)<br />
Types of OI<br />Chronic illness<br />Four Types of OI<br />Type I OI: normal life span, less severe bone breaks and fractures<br />Type II OI: most severe, result in death within the first year of life<br />Type III OI: severe but have longer lifespans than type II, many fractures early in life, develop bone deformities<br />Type IV OI: moderately severe, need crutches/braces to walk<br />
Prevention<br />Visiting a genetic counselor before conceiving can help alert a couple about OI history in their family<br />Can not be prevented<br />No cures for disease, but treatments <br />
Treatment<br />Bisphosphonates treat osteoperosis, but can increase strength in bones for OI patients<br />Can help decrease pain in bones<br />Swimming is a low contact activity that can help with strength<br />More severe cases: surgery for metal rod placement against bones<br />
Terminal?<br />The disease is terminal <br />Person with OI must take precaution with every move they make for the rest of their lives<br />
