Severe Chronic Neutropenia International Registry

The Severe Chronic Neutropenia International Registry (SCNIR) was established in 1994 to monitor the clinical course, treatment, and disease outcomes in patients with severe chronic neutropenia (SCN). The Registry has the largest collection of long-term data on patients with this condition in the world. Participation in the Registry benefits patients, their families and the physicians who treat them by providing the most up to date information to them on the natural history of SCN and its treatment options.

SCNIR’s Mission Statement

Our mission is to establish a global database of treatment and disease-related outcomes for persons diagnosed with SCN. Collection of this information will lead to improved medical care and is used for research to determine the causes of neutropenia.
