Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Cystinosis is a generalized lysosomal storage disease with a reported incidence of about 1:180,000 live births. There are estimated 110-140 cases in France (approximately 500 in Western Europe). The disease is caused by mutations in the CTNS gene coding for cystinosin, a lysosomal carrier protein. The lysosomal cystine accumulation leads to cellular dysfunction in many organs. The first symptoms start at about 6 months of age. In the absence of specific therapy, end stage renal disease occurs between 6 and 12 years of age. Survival beyond this age is associated with the development of extra-renal complications.

Renal transplantation and the availability of cystine-depleting medical therapy, cysteamine (EU/1/97/039/001, EU/1/97/039/003), have radically altered the natural history of cystinosis. Cystinosis is a good example of a "paediatric" disease where patients now survive into adolescence and adulthood. These individuals have complex, multisystem problems that require on-going care.

Despite some progress in recent years there are still significant limitations in the knowledge of diagnostic and therapeutic procedures. A first European registry was launched in 2011, using the CEMARA application developed by the Banque Nationale de Données Maladies Rares (BNDMR, CNIL authorisation number: 1187326), allowing the collection of data from France, Belgium and Italy. The objective of the current study is to translate this database into a cohort study that will allow and facilitate the collection of a wider range of data including clinical, and personal data such as quality of life data, from an increased number of European countries, improve the monitoring, data-management and analysis of the data, offer the possibility for patients to actively participate to and benefit from the study by developing a module in which patients will enter their own data on quality of life with a direct feed-back on the general results.

This project is a unique opportunity for building a consensual European academic cohort not based on company driven, "drug-oriented" objectives.

The cohort will collect clinical details to analyse patient outcomes thus providing audit of patient care \& clinical effectiveness. It will be possible, through the cohort, to indicate where improvements need to be made and ultimately improve care to the highest standards.
