Digeorge Syndrome
Remember it's a T-cell deficiency which they are prone to Tetany (due to HypOcalcemia). Associated with congenital defect (truncus arteriosus). Risk of viral/fungal/protozoan infection, esp w/PCP (just like HIV)
Deletion of 22q11
embryology
- thymus (3rd pouch-dorsal wings)
- parathyroid (3rd + 4th)
both failed to develop
