Medical problems commonly associated with DiGeorge syndrome include heart defects, (40% of individuals), particularly conotruncal malformations (tetralogy of Fallot, interrupted aortic arch, ventricular septal defect, and persistent truncusarteriosus), poor immune system function, a cleft palate, learning difficulties (90%), hypocalcemia (50%) skeletal abnormalities, psychiatric and behavioral disorders. The number and severity of problems associated with DiGeorge syndrome vary greatly.
