Description

The 22q11.21 interstitial deletion corresponds to the critical region of chromosome 22q11.2 deletion syndrome (a.k.a., Velocardiofacial syndrome (VCFS) or DiGeorge syndrome (DGS) (OMIM #192430; OMIM #188400). Haploinsufficiency of the TBX1 gene in particular is responsible for most of the clinical features of DiGeorge syndrome. Individuals with chromosome 22q11.21 deletion syndrome have a range of phenotypic findings, including congenital heart defects, particularly conotruncal malformations (tetralogy of Fallot, interrupted aortic arch, ventricular septal defect, and truncus arteriosus), palatal abnormalities, characteristic facial features, learning difficulties, and immune deficiency (GeneReviews [Internet]. Available from: https://www.ncbi.nlm.nih.gov/books/NBK1523/). Familial cases with microdeletion of this region are relatively common.
