  UNSW Embryology-OMIM DIGEORGE SYNDROME
DiGeorge syndrome overlaps clinically with the disorder described by the Japanese as 'conotruncal anomaly face syndrome' (Kinouchi et al., 1976; Takao et al., 1980; Shimizu et al., 1984), where the cardiovascular presentation is the focus of attention.
Shprintzen (1994) objected to 'lumping' velocardiofacial syndrome with the DiGeorge anomaly, arguing that there is 'no valid evidence to suggest that velocardiofacial syndrome is etiologically heterogeneous...[whereas] the DiGeorge anomaly is known to be so.' Hall (1993) cited data of Driscoll et al.
She stated that '...68% of Shprintzen syndrome patients...have been recognised to have deletions of 22q11.' Shprintzen (1994) refuted her statement, maintaining that it could accurately be stated that deletion was found in 68% of patients sent to the Driscoll laboratory with a diagnosis of velocardiofacial syndrome made by other clinicians.

Shprintzen named this group of features velo-cardio-facial syndrome, but the syndrome was also referred to as Shprintzen syndrome.
In other words, this was the same syndrome, but because several different researchers in different areas of expertise had described it, the syndrome carried multiple names.

If the parents of an individual with the 22q11.2 deletion syndrome have normal FISH studies, the risk to sibs is low, but greater than that of the general population because parents with germline mosaicism or low-level somatic mosaicism have been identified.

Shprintzen syndrome is the most common disorder to affect a group of neighbouring genes and one of the most common causes of multiple abnormalities in humans.
The condition is passed on in an autosomal dominant way, but may also occur as a new mutation, where there's no family history (in some cases it may be that the parent is mildly affected and has never been diagnosed).

The COMT and TBX1 genes are associated with 22q11.2 deletion syndrome.
This condition is often described as a contiguous gene deletion syndrome because a deletion in chromosome 22 leads to the loss of many genes that are close together.
The inheritance of 2q11.2 deletion syndrome appears to be autosomal dominant because a deletion in one copy of chromosome 22 in each cell is sufficient to cause the condition.

 Velocardiofacial Syndrome
Velocardiofacial syndrome, (VCFS), a rare genetic disorder, is characterized by abnormalities of the head and facial (craniofacial) area, heart defects that are present at birth (congenital heart defects), diminished muscle tone (hyptonia), mild small stature, slight delays in the acquisition of skills requiring the coordination of mental and muscular activities (psychomotor retardation), and learning disabilities.
The heart defect most often associated with velocardiofacial syndrome is an abnormal opening in the fibrous partition (septum) that separates the heart's two lower chambers (ventricular septal defect).
Velocardiofacial syndrome is inherited as an autosomal dominant genetic trait and is sometimes known as chromosome 22q11 deletion spectrum because it is associated with multiple identifying features known to occur as a result of a deletion of genetic material on chromosome 22.

Conditions associated with DiGeorge syndrome are 22q11 deletion syndromes, velocardiofacial syndrome (VCFS or Shprintzen syndrome), conotruncal anomaly face syndrome, Cayler syndrome, Opitz-GBBB syndrome, and CHARGE (coloboma [eye], heart anomaly, atresia [choanal], retardation [mental and growth], genital anomaly, ear anomaly) syndrome.
DiGeorge anomaly (DGA) is a congenital immunodeficiency characterized by abnormal facies; congenital heart defects; hypoparathyroidism with hypocalcemia; cognitive, behavioral, and psychiatric problems; and increased susceptibility to infections.
The constellation of defects is not a syndrome resulting from a single cause, but rather the failure of an embryological field to develop normally.

Ninety percent of patients with the features of this syndrome are missing a small part of their chromosome 22 at the q11 region.
Sometimes, other chromosome defects have been associated with these features, as well as maternal diabetes, fetal alcohol syndrome, and prenatal exposure to Accutane® (a medication for cystic acne).
