22q11.2 Deletion syndrome

What is 22q11.2 Deletion syndrome?

22q11.2 deletion syndrome, or as it is sometimes referred to, DiGeorge syndrome, is a genetic disorder. It is often referred to by several different names and presents with a wide range of symptoms that can affect almost any part of the body. The characteristics and symptoms of the syndrome vary greatly between individuals and even amongst individuals with the same family syndrome.

What gene changes cause 22q11.2 Deletion syndrome?

22q11.2 deletion syndrome occurs due to the deletion of DNA base pairs on chromosome 22. Known as a contiguous gene deletion syndrome, researchers are currently identifying the specific gene deletions that contribute to each of the syndrome's various symptoms.

1 in every 4,000 live births in the US will present with 22q11.2 deletion syndrome, and most cases are the first in a family. In 1 in 10 cases, one parent will pass the deletion to their child.

What are the main symptoms of 22q11.2 Deletion syndrome?

22q11.2 deletion syndrome and DiGeorge syndrome represent a spectrum of syndromes that share congenital heart defects, immunological abnormalities, and variable facial features.

The main symptoms of 22q11.2 deletion syndrome can vary significantly between individuals. Congenital heart defects are a common feature of the syndrome. Other health conditions include cleft palate, feeding issues, gastrointestinal problems, problems with the immune system and resultant infections, low levels of calcium in the blood and related health conditions, ENT issues, and missing or damaged kidneys.

Mental health conditions associated with 22q11.2 deletion syndrome include increased risk for OCD, autism, ADD, and delays in growth, speech, and the potential for learning disabilities. Behavioral and developmental delays are common.

How does someone get tested for 22q11.2 Deletion syndrome?

The initial testing for 22q11.2 deletion syndrome can begin with facial analysis screening, through the FDNA Telehealth telegenetics platform, which can identify the key markers of the syndrome and outline the need for further testing. A consultation with a genetic counselor and then a geneticist will follow. 

Based on this clinical consultation with a geneticist, the different options for genetic testing will be shared and consent will be sought for further testing.
