Methods: Two hundred three children with genetically proven primary immunodeficiency diseases (PIDs) from 197 unrelated families were enrolled from January 2005 to December 2011. @@@ Results: On the basis of criteria developed by the International Union of Immunological Societies, 79 patients were diagnosed as other well-defined immunodeficiency syndromes (38.9%), 62 (30.6%) with predominant antibody deficiencies, 26 (12.8%) with congenital defects of phagocyte, 25 (12.3%) with T- and B-cell immunodeficiency and 11 (5.4%) with diseases of immune dysregulation. The median time to the diagnosis was 27.9 months and the patients had a wide range of clinical presentations. In addition, a total of 23 pathogenic genes were identified and 213 mutations were detected, including 42 novel mutations. @@@ Conclusions: With the increase in the awareness of PIDs and diagnostic competence, more PID patients will be diagnosed and we will be able to more accurately identify the frequency and the distribution of PIDs in the most populous country in the world.
