Glossary
- Novel: An unusual or non-standard form. OI Type V and Type VI are referred to as "novel forms of OI," because they have a significant characteristic that is different from the four generally recognized types. No defect in the genes that control the body's production of Type 1 collagen has been found in people who have been diagnosed with these types of OI. The other types of OI all are associated with defects in Type 1 collagen.
