About 22q11.2 Deletion Syndrome

22q11.2 Deletion Syndrome affects as many as 1 in 2,000 to 1 in 4,000 persons worldwide. Formerly known as DiGeorge syndrome, velocardiofacial syndrome, and Sphrintzen syndrome, 22q11.2 Deletion Syndrome is caused when a small amount of genetic material, termed a microdeletion, is missing on chromosome 22. As a result of the deletion, many body organs may be affected.  Not all patients are affected in the same way. The diagnosis should be considered in any person with one or more of the following features:

  • Certain heart defects present at birth
  • Low calcium levels
  • Immune system problems (i.e. a child with multiple infections)
  • Cleft palate
  • Speech and/or swallowing difficulties
  • Behavior and learning disabilities

About 22q11.2 Duplication

22q11.2 Duplication is caused by an extra piece of genetic material on the 22nd chromosome. The duplication can cause a wide range of health issues. However, many patients have no noticeable symptoms. Some symptoms that can occur include:

  • Hypotonia (low muscle tone)
  • Developmental delays 
  • Intellectual disability
  • Psychiatric illness

Individuals with 22q duplication may also exhibit any of the features known to be associated with 22q deletion.
