[7] The syndrome was first described in 1968 by American physician Angelo DiGeorge. Children often perform lower on speech and language evaluations in comparison to their nonverbal IQ scores. [51] The key is to identify each of the associated features and manage each using the best available treatments. The chances of a person with DiGeorge syndrome having an affected child is 50% for each pregnancy; (2) Parents who have affected children, but who were unaware of their own genetic conditions, are now being diagnosed as genetic testing become available; (3) Molecular genetics techniques such as FISH (fluorescence in situ hybridization) have limitations and have not been able to detect all 22q11.2 deletions. DiGeorge syndrome, also called 22q11.2 deletion syndrome, is a genetic condition caused by missing a part of chromosome 22. The rate of occurrence is estimated at approximately 1 in 4,000 people. [21], Individuals with DiGeorge syndrome also have a higher risk of developing early onset Parkinson's disease (PD). Immunologic care for patients with DGS includes monitoring the overall immune system including the numbers and function of T-lymphocytes. Its a condition common in children.

[58], The number of people affected has been expected to rise because of multiple reasons: (1) surgical and medical advances, an increasing number of people are surviving heart defects associated with the syndrome. It is nearly impossible to predict which symptoms a child will develop. [11][12] In late 1981, the underlying genetics were determined. In addition to physical manifestations, DiGeorge syndrome is associated with a high prevalence of psychiatric disorders, such as intellectual disability, schizophrenia and attention-deficit/hyperactivity disorder. For patients who do not have the 22q11 microdeletion, a DGS diagnosis can still be made on the basis of the characteristic combination of clinical features and by excluding a diagnosis of other syndromes.
