For example, some patients with DGS have severe cardiac anomalies; some have none at all. DiGeorge Syndrome (DGS), also referred to as Velo-Cardio-Facial Syndrome (VCFS), is an immunodeficiency disorder characterized by various congenital abnormalities. DGS is the most common microdeletion syndrome. Autoimmune disease occurs when the immune system inappropriately attacks its own body.
