The term 22q11.2 deletion syndrome covers terms once thought to be separate conditions, including DiGeorge syndrome, velocardiofacial syndrome and other disorders that have the same genetic cause, though features may vary slightly. The classical presentation is a triad of cardiac anomalies, hypoplastic thymus, and hypocalcaemia (resulting from parathyroid hypoplasia). [7] While the symptoms can vary, they often include congenital heart problems, specific facial features, frequent infections, developmental delay, intellectual disability and cleft palate. Some children can be severely ill and very occasionally may die from it, but many others may grow up without realising they have it. Not only are affected infants more susceptible to infections, but their bodies cannot effectively fight off the infections either. Characteristic signs and symptoms may include birth defects such as congenital heart disease, defects in the palate, most commonly related to neuromuscular problems with closure (velopharyngeal insufficiency), learning disabilities, mild differences in facial features, and recurrent infections.

Suite 310 This content does not have an Arabic version. These atypical T cells have not gone to school and have not learned what is self. The atypical T cells then attack the body causing rash, and often also diarrhea or liver damage. In some children, all of the classical features are present and the diagnosis of DGS is made very early. However, almost everyone with this syndrome needs treatment from specialists in a variety of fields. The neural crest forms many of the structures affected in DiGeorge syndrome, including the skull bones, mesenchyme of the face and palate, the outflow tract of the heart, and the thymus and parathyroid stroma. There's also usually a hole in the wall between the lower heart chambers, called the ventricles. [16], Salient features can be summarized using the mnemonic CATCH-22 to describe 22q11.2DS, with the 22 signifying the chromosomal abnormality is found on the 22nd chromosome, as below:[17].
