Knowledge of rare diseases is often scattered among many data collections and patient registries. The assessment of the severity of rare diseases and the development of treatment and care for patients is difficult. A survey conducted in Italy aims to provide a systematic picture of the emergence of rare diseases. The data was collected from 247 specialized centers and from 200 000 records and the age and gender data of the patients was given for more over 400 diseases. The information provided by the research represents a unique basis allowing the prioritization of relevant health treatment and research activities. You can read more about the research here.
