Background
The Rare Diseases Clinical Research Network (RDCRN) Brittle Bone Disorders (BBD) Consortium Contact Registry is a vehicle through which patients (and their families) can register with the RDCRN to receive information about the activities of the BBD Consortium and learn about new studies in which they might be interested in participating. The RDCRN has developed surveys to be sent to the Contact Registry registrants to learn more about disease outcomes (patient-reported outcomes) and collect more detailed diagnostic data.
About this Study
Individuals with OI will be recruited via the BBD Contact Registry. The BBD Contact Registry consists of over 900 participants with OI.
Participants enrolled in the BBD Contact Registry will receive an email inviting them to participate in the study. Interested participants will be directed to the informed consent document. After agreeing to participate, participants will be directed to the study web portal. The study web portal will be developed and maintained by the Data Management and Coordinating Center at the University of South Florida (USF).
Participants will complete a series of short surveys about their OI, including diagnosis, treatment information and quality of life.
Targeted Enrollment: 300
To be eligible to participate, you must be:
- Enrolled in the BBD Contact Registry
- English speaking
- 2 years of age or older
You are not eligible to participate if:
- You cannot provide informed consent
- You are unable to complete the study surveys

Summary
Osteogenesis imperfecta (OI) is a group of congenital and heritable bone disorders that currently affects at least 50,000 people in the United States. OI varies in severity from perinatally lethal to mild forms. The majority of cases is caused by a dominant mutation in type I collagen genes (COL1α1 and COL1α2), altering the quantity or quality of type I collagen.
Although OI is typically characterized as a disease of the bone, it is perhaps more accurately described as a connective tissue disorder. Type I collagen is a major constituent of lung connective tissue. Respiratory insufficiency is the leading cause of death in patients with OI. Thus, it is important and necessary to understand the etiology of the restrictive pulmonary physiology in the OI population.
Details
This study is cross-sectional. At the participant's one study visit, data will be obtained at a single point in time and reflect the patients' current condition. Evaluations will include family and medical history, self-report questionnaires, physical evaluation, diagnostic studies, and radiographic studies. Eighteen participants will be enrolled, ideally within one year. Participants will be enrolled regardless of OI type since Bronchial Wall Thickening, a finding we are attempting to validate, was observed in all types of OI. Interested males with OI will be preferred over females to compensate for our highly female original cohort and determine if sexual dimorphism exists for cardiopulmonary outcomes in people with OI. Smokers will not be excluded.
