National Rare Diseases Registry System of China and Related Cohort Studies: Vision and Roadmap

Rare diseases are major challenges in healthcare and medical research and are the basis of national development strategies in many countries. However, inadequate definition of rare diseases and lags in orphan drug development in China hinder rare disease research. In response, the first National Rare Diseases Registry System of China (NRDRS) was established, and various cohort studies have been launched since 2016. More than 20 top academic institutions in China are currently participating in this joint effort to carry out nationwide registration of rare diseases. The primary objectives are to establish standardization for the registration platform, build biobanks of genomic data, and create partnerships for data sharing and research collaboration. Innovative informatics technologies have been implemented to develop the NRDRS, including employment of ontological and knowledge bases to render standardization and support standard of care. Development of informatics analysis tools will facilitate accurate and more efficient diagnoses for rare diseases. Long-term research collaboration is encouraged to create additional national rare disease networks for research translation and to benefit patients with rare diseases. The NRDRS of China and related cohort studies are anticipated to enlighten rare disease research significantly in China.
