Velocardiofacial/DiGeorge Syndrome Deletion/Duplication

Test Background Over 90% of patients with classical DiGeorge syndrome or velocardiofacial syndrome (classical DGS/VCFS) have a de novo 22q11.2 deletion, and 7% of patients have an inherited 22q11.2 deletion from a parent. Deletions in this region are also associated with other phenotypes including isolated cardiovascular malformations and Opitz G syndrome. A small number of…
