The defects are usually related to face, heart, and immune system abnormalities. In a small percentage of children with complete DiGeorge syndrome, there is no identifiable genetic cause for the disorder, and no symptoms indicative of a larger syndrome.

It is reasoned that a limited phonemic inventory and the use of compensatory articulation strategies is present due to the structural abnormalities of the palate. DiGeorge syndrome isnt common. They usually result in a lack of oxygen-rich blood reaching the body. DiGeorge syndrome or 22q11.2 deletion syndrome is one of the most common genetic microdeletion syndromes in humans. 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. The 22q11.2 deletion has also been identified in the majority of patients with DiGeorge syndrome (McDonald-McGinn et al., 2010). Most people with DiGeorge syndrome are missing a small piece of chromosome 22 known as 22q11.2. 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. It is normally located in the upper area of the front of the chest behind the breastbone. Although infants with partial DiGeorge syndrome usually outgrow the hypoparathyroidism in approximately 12 months, approximately 80% of infants with complete DiGeorge syndrome have long term problems maintaining safe calcium levels.
