In epidemiology, a register is a file of data concerning all cases of one or more diseases in a defined population, so that the cases can be related to the base population1 . These registers are essential epidemiological resources for analysing risks in the population and for the study of aetiological hypotheses of diseases. They are particularly useful in the case of rare diseases due to their low prevalence, the dispersion of information and the degree of ignorance inherent to these pathologies.
