The parathyroids are small glands found in the front of the neck near the thyroid gland, hence the name parathyroid. They function to control the normal metabolism and blood levels of calcium. DiGeorge syndrome, also known as 22q11.2 deletion syndrome, is a syndrome caused by a microdeletion on the long arm of chromosome 22. However, parents can be screened for the 22q11 deletion to see if they are carriers of DGS. In most cases, this congenital (present at birth) disability occurs when a small piece of chromosome 22 is missing. Developmental trajectories of psychiatric diseases among patients with DiGeorge syndrome. [62][13] Some experts support changing the name of both DiGeorge and velocardiofacial syndromes to CATCH-22. Between 1-2% of patients with DGS completely lack T-cells. It is characterized by hypocalcemia due to hypoparathyroidism, heart defects, and thymic hypoplasia or aplasia. Treatment of the low calcium and hypoparathyroidism may involve calcium supplementation and replacement of the missing parathyroid hormone. Chromosome 22q11.2 deletion syndrome.

DiGeorge syndrome (DGS) is a primary immunodeficiency disease (PIDD) associated with susceptibility to infections due to decreased T cell production and function due to an absent or poorly developed thymus. In some cases people with DiGeorge syndrome have no symptoms at all. This may be due in part to structural differences such as a cleft palate (a hole in the roof of the mouth) or to functional difficulties (either VPI or oral apraxia). You cant prevent it because it results from the sharing of genetic information during conception. DiGeorge syndrome is a genetic disorder that can affect many parts of the body.
