What is 22q11.2 Deletion Syndrome?

Chromosome 22q11.2 deletion syndrome, also called velocardiofacial syndrome and DiGeorge syndrome, is caused by the deletion of a small segment of the long arm of chromosome 22 and is linked to over 180 physical, psychological and behavioral anomalies.  Children with the syndrome experience some degree of developmental delay and learning difficulties. Most of these children have at least some of the following physical conditions: congenital heart defects, cleft palate or velopharyngealinsufficiencies, immune deficiencies or neonatal hypocalcemia.  Likewise, most of them are at increased risk for some of the following behavioral and psychological disorders: attention deficit hyperactivity disorder, autism spectrum disorders, oppositional-defiant disorder, obsessive-compulsive disorder and schizophrenia.
