DiGeorge syndrome, also called chromosome 22q11.2 deletion syndrome, is a genetic condition that results in developmental problems in many of the bodys systems. Associated conditions include kidney problems, schizophrenia, hearing l The gene coding for C22orf25 is located on chromosome 22 and the location q11.21, so it is often associated with 22q11.2 deletion syndrome. Treatment of the low calcium and hypoparathyroidism may involve calcium supplementation and replacement of the missing parathyroid hormone.

Epub 2014 Dec 16. Ninety percent of individuals with DGS are missing a piece of genetic information on chromosome 22 at the q11 region, referred to as a deletion on chromosome 22. A parent with DiGeorge syndrome has a 50 percent chance of passing along the deletion to their child with each pregnancy. [32], Research in mouse models has shown that deletion of Tbx1 leads to several defects similar to those seen in humans, mainly affecting development of the great arteries and the thymus.[38][39].
