Self-administered questionnaire
The self-administered questionnaire was previously prepared by the research team for another project. It includes 14 questions addressing the dentition, fractures, joint hypermobility, height, and eye abnormalities present in the participants or their relatives. This questionnaire covers the clinical manifestations of rare bone diseases such as osteogenesis imperfecta, pycnodysostosis, hypophosphatasia, and osteopetrosis. This self-administered questionnaire will be filled online by participant. Average completion time of 20 minutes.
Family tree
For the family tree, this step is done by a telephone interview lasting a maximum of 45 minutes, depending on the size of the participant's family. The researcher will be able to reconstruct the family history with the index case. The family tree will then contain the family history up to the second degree of kinship with respect to the index cases. The information collected through the index cases when creating the family tree must include, for each relative, biological sex, as well as information on the presence or absence of a rare or genetic bone disease and clinical signs associated with these diseases, such as short stature, bone deformities, deafness, eye problems, etc.
