Some signs may be apparent at birth, such as cleft palate or a congenital heart defect, whereas others may only be noticed in later childhood. [31] Of the 3050 genes in the deleted region, a number have been identified as possibly playing a role in the development of some of the signs and symptoms. 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. DiGeorge syndrome (DGS) is one of a group of phenotypically similar disordersincluding velocardiofacial syndrome (VCFS, or Shprintzen syndrome) and conotruncal anomaly face (CTAF) syndromethat share a microdeletion of chromosome 22q11.2, a region known as the DGS critical region (see the image below).
