Registry of Multiple Osteonchodromas

Recruiting

• Conditions: Multiple Osteochondroma

• Registration Number: NCT04133285
• Lead Sponsor: Luca Sangiorgi

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.

Detailed Description

The common way to collect patient information is frequently chaotic and inconvenient (sometimes even unsafe), particularly when dealing with rare diseases. The need to simplify the diagnostic process and to overcome the difficulties of data storage and analysis, suggested in 2013 to implement the Registry of Multiple Osteochondromas (REM).

The REM relies on an IT Platform named Genotype-phenotype Data Integration platform -GeDI.This solution, realized by a collaboration among Medical Genetic Department and a local software-house (NSI - Nier IT Solution), is a General Data Protection Regulation (GDPR)-compliant, multi-client, web-accessible system and it has been designed according to current medical informatics standards (Orphanet code, ICD-10, Human Genome Variants Society, Findability Accessibility Interoperability Reusability Principles). GeDI is continuously implemented to improve management of persons with Multiple Osteochodromas and to help researchers in analysing collected information. REM is articulated in main sections:

* Personal data: it comprises general information, birth details and residence data

* Patient data: including the patients internal code, the hospital code and other details on patients

* Diagnosis: the diagnosis, the status (affected, suspect, etc.), age at diagnosis, comorbidities, allergies, etc.

* Genogram: a tool to design family transmission of the disease, flanked by info on diseases status of all included relatives

* Clinical events: records more than 20 signs and symptoms of Multiple Osteochondromas and 12 additional items to describe the disease

* Genetic Analysis and Alteration: including technique, sample information, duration of analysis, etc. In addition, this section comprises detailed information on detected pathological variants (gene, international reference, DNA change, Protein change, genomic position, etc.)

* Visits: it includes the typology of the visit (genetic, orthopaedic, rehabilitation, paediatric, etc.), the date of the visit, treatment, prescription, imaging, etc.

* Surgeries: this section contains information on the surgeries type, the age of the patients, the site/localization of the procedures, etc.

* Documents: this repository is allowed to store all type of documents (radiological reports, imaging, consents, clinical reports, etc.)

* Consents: this section comprises a complete overview of all collected consents, including the date of collection.

* Samples: it comprises the type of samples (DNA, tissue, whole peripheral blood, etc.)

Primary Outcome Measures

Name	Time	Method
Natural History and Epidemiology in terms of clinical, genetic and functional evaluation	25 years	To maintain an established registry in order to assess epidemiology and natural history (such as incidence, prevalence, etc.) of Multiple Osteochondromas.; Collection of: 1. physical examinations data: assessment of severity of the disease (defined according to Mordenti et al classification); 2. orthopaedic and functional data: stature (cm), weight (kg), number and localization of sites affected by osteochondromas, 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; Clinical, orthopaedic and functional features are updated at each follow up. Clinical reports, medical charts, genetic report and imaging are the primary source of data.

Secondary Outcome Measures

Name	Time	Method
Genotype-Phenotype Correlation among clinical features and molecular background	25 years	The secondary outcome comprises the correlation between genotype and phenotype. This includes, but is not limited to clinical features and genetic background. This will be pursued using the information collected during visits and follow-ups and the genetic information resulting from molecular investigations.
