Causes And Complications Linked To DiGeorge Syndrome

DiGeorge syndrome is one of several disorders caused by a broader condition called 22q11.2 deletion syndrome. It occurs when a portion of the chromosome 22 doesn't exist. The deletion leads to poor development of multiple systems in the body. In the past, multiple disorders now covered under the 22q11.2 deletion umbrella were thought to be separate conditions. These include DiGeorge syndrome, velocardiofacial syndrome, plus any other conditions caused by the same genetic factors.
