Genetics Home Reference




DiGeorge syndrome, also called 22q11.2 deletion syndrome, is a disorder caused by a defect in chromosome 22. It results in the poor development of several body systems.

Medical problems commonly associated with DiGeorge syndrome include heart defects, poor immune system function, a cleft palate, complications related to low levels of calcium in the blood, and delayed development with behavioral and emotional problems.

The number and severity of symptoms associated with DiGeorge syndrome vary greatly. However, almost everyone with DiGeorge syndrome needs treatment from specialists in a variety of fields.

Before the discovery of the chromosome 22 defect, the disorder was known by several names — DiGeorge syndrome, velocardiofacial syndrome, Shprintzen syndrome, CATCH22 and others. Although the term “22q11.2 deletion syndrome” is frequently used today — and is generally a more accurate description — previous names for the disorder are still used.
