<unk>  is a rare genetic condition caused by a tiny missing part of one of the body’s 46 chromosomes – chromosome 22.<unk>  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<unk> .2<unk>  deletion was in 1999. There have since been hundreds of cases reported worldwide.<unk>  seems to occur equally often in males and females. There are reports of people who are unaffected by carrying the deletion and only discovered it after their child was diagnosed. It seems that the<unk> .2<unk>  deletion can be "silent" and it is unknown how many people may have a silent form of this syndrome.
