Abstract |
The recognition that deletion of 22ql1 is a common cause of varied malformations and clinical disorders took more than a decade to achieve. Deletions of chromosome 22ql1 have been seen in association with DiGeorge syndrome (DGS) and velo¡ⓒ cardio-facial syndrome (VCFS). The large clinical overlap between DiGeorge syndrome and velo-cardio-facial syndrome suggest an aetiological connection. CATCH 22 synd¡ⓒrome is characterized by cardac defects, abnormal facies, thymic hypoplasia, cleft palate, and hypocalcemia resulting from 22ql1 deletions which includes DiGeorge syndrome, velocardiofacial syndrome, and conotruncal anomaly facial syndrome. Cardiovascular anomalies in CATCH 22 mainly consist of cardiac outflow tract defects or aortic arch anomalies such as tetralogy of Fallot, truncus arteriosus, and interruption of aortic arch. The frequency of association with deletion within chromosome region 22q11 is more than 80%. We report the clinical findings in 7 cases. |
