Chapter 11: Velo-Cardio-Facial Syndrome/22q11 Deletion Syndrome
Velo-Cardio-Facial Syndrome/22q11 Deletion Syndrome
Brief Historical Perspective
Velocardiofacial syndrome (VCFS) is the most common human genetic deletion syndrome and is associated with deletions in chromosome 22. VCFS was once considered a rare congenital disorder but since the advent of molecular genetics, this view has now been countered. In 1992, a major breakthrough occurred in the study of VCFS and disorders related to chromosome 22 when deletions were specifically localized to the long arm of chromosome 22 (22q11) (Scambler et al., 1992). Subsequently, several reports followed which confirmed the microdeletion in chromosome 22 (Driscoll et al., 1992; Kelly et al., 1993). Tremendous interest in the syndrome still continues today as it is a complex disorder that affects essentially every organ system in ...
