Severe congenital neutropenia (SCN)

Severe congenital neutropenia (SCN) is a rare blood disorder characterized by abnormally low levels of certain white blood cells (neutrophils) in the body (neutropenia). Neutrophils play an essential role in fighting bacterial infections by surrounding and destroying invading bacteria (phagocytosis).

Symptoms associated with severe congenital neutropenia include recurring fevers, mouth sores (ulcers), and/or inflammation of the tissues that surround and support the teeth (periodontitis). Due to low levels of neutrophils, affected individuals may be more susceptible to recurring infections that, in some cases, may result in life-threatening complications.
