22q11.2 distal deletion syndrome is a rare genetic condition caused by a tiny missing part of one of the body’s 46 chromosomes – chromosome 22. 22q11.2 distal deletion syndrome appears to be a recurrent genomic disorder distinct from DiGeorge syndrome (DGS; 188400) and velocardiofacial syndrome (VCFS; 192430).The first published description of a person with a 22q11.2 distal deletion was in 1999. There have since been more than 50 cases reported in the medical literature worldwide.
