These problems, usually present at a babys birth or in early childhood, include heart defects, an impaired immune system and developmental delays. [62][13] Some experts support changing the name of both DiGeorge and velocardiofacial syndromes to CATCH-22. The majority cases are a result of a de novo (new to the family) deletion. These include irradiating all blood products to prevent graft vs. host disease and ensuring the blood products are free of potentially harmful viruses. These patients require prompt medical attention since they are severely immunocompromised. The parathyroid defect often becomes less severe over time.

Some infants are diagnosed via newborn screening. The condition may affect several body sites due to a genetic defect called deletion on the long arm (called "q" arm) of chromosome number 22. Doctors may suspect 22q11.2 deletion syndrome: Each person has two copies of chromosome 22, one inherited from each parent. The need for therapy of the T-lymphocyte defect varies. The outlook for people with DiGeorge syndrome varies depending on the severity of their congenital disabilities. In other people, all of the different organs and tissues may not be affected, and the organs and tissues that are involved may be impaired to different degrees so that the presentation is more subtle and the diagnosis is not made until later on in life when a speech delay, feeding problems or autoimmune disease are noted.

Although neither FGF18 or TBX1 are expressed in the neural crest cells, TBX1 might have a role in the regulation of FGF18 expression, ensuring that the differentiation of these cells in the pharyngeal region is correct. To determine that a child had no thymus, blood testing must not detect T cells emerging from the thymus. Parathyroid hormone plays a role in regulating the levels of calcium and phosphorus in the blood. Point mutations in this gene have also been observed in individuals with DiGeorge syndrome.
