Even though rare disorders usually have limited case numbers, they have induced huge impacts on patients and their families, and has heavily burdened on our society and healthcare system as well. Therefore, it is essential to detect the occurrence of disorders and thus take appropriate measures as early as possible. The preventive goal is based on comprehensive understanding on rare disorders, available diagnostic and therapeutic approaches. However, studies related to rare disorders are often impeded by limited sample sizes and infrequent exchange of research materials among institutes. After referring to foreign experiences, the investigators have noticed that a non-profit tissue bank which can reposit biological samples and thus provide researchers access to samples, may be a solution. Through sharing this public asset, the investigators believe not only quantity and quality of rare disorder studies will be improved, the collaboration between various research institutes can also be strengthened afterwards. Most important of all, those achievements can ultimately benefit patients, families and the whole society.
