Brief Summary

REM is a retrospective and prospective registry, finalized to care and research. It is articulated in main sections - strongly related and mutually dependent on each other - corresponding to different data domains: personal information, clinical data, genetic data, genealogical data, surgeries, etc.. This approach has been individuated in order to corroborate and integrate data from different resources and aspects of the diseases and to correlate genetic background and phenotypic outcomes, in order to better investigate diseases pathophysiology. Due to legal requirements, institutional directives and organizational issues, we are unable to include individuals residing outside Italy in the registry at this time. We are currently engaged in the preparation of a recruitment process for individuals residing outside Italy.

Outcome Measures

Primary Outcomes (1)

  • Natural History and Epidemiology in terms of clinical, genetic and functional evaluation

    To maintain an established registry in order to assess epidemiology and natural history. Collection of: 1. physical examinations data: assessment of severity of the disease 2. orthopedic and functional data: stature (cm), weight (kg), number and localization of sites affected by enchondromas, site of malignant transformation, definition of deformities (localization and number), definition of limitations (localization and number) 3. surgical procedures: type, number and site of surgeries disease-related and age at surgeries 4. genetics background: target gene, type of mutation, type of variant detected, clinical significance 5. family history: inheritance in maternal or paternal line 6. treatment information: pharmacological, devices, supplements, and other treatments Clinical, orthopedic, surgical, treatment and functional features are updated at each follow up. Clinical reports, medical charts and imaging are the primary sources of data.

    25 years

Secondary Outcomes (1)

  • Genotype-Phenotype Correlation among clinical features and eventual molecular background

    25 years

Other Outcomes (1)

  • Longitudinal study of disease evolution (including prospective and retrospective data)

    25 years
