Severe combined immunodeficiency (SCID)
Severe combined immunodeficiency (SCID) is a serious primary immunodeficiency. There are many different genetic causes of this rare condition. In SCID, certain parts of the body's immune system do not work correctly. This makes individuals with SCID highly susceptible to serious and life-threatening infections beginning at an early age. Early identification can lead to prompt treatment, which can improve the chances for a good health outcome for children with SCID. Support is available for families of children and youth with SCID.
