This copy number variation is associated with an extraordinary range of clinical features, which led initially to its association with several diagnostic labels. Since 1997 work on clinical and basic science aspects of the syndrome and the genes reduced to hemizygosity have provided a wealth of information pertaining to both best practice care and underlying biology.

An infant with DiGeorge syndrome, multiple comorbidities, and truncus arteriosus type II underwent repair complicated by heart block necessitating placement of a dual-chamber bipolar pacing system with right ventricular leads and subsequent resynchronization with placement of left ventricular apical pacing leads. Resynchronization therapy improved QRS duration from 180 ms to 100 ms and ejection fraction from 25% to 54% over the course of 4 weeks with gradual return to normal function and eventual discharge.
