The association between truncus arteriosus and chromosome 22q11 deletion is well recognized, but the frequency of a chromosome 22q11 deletion has not been characterized in a large series of patients with truncus arteriosus, and little is known about cardiovascular morphologic features associated with a chromosome 22q11 deletion in this group of patients. We prospectively enrolled 50 consecutive patients with truncus arteriosus who were admitted to The Children's Hospital of Philadelphia between November 1991 and December 2001. Patients were studied for chromosome 22q11 deletion using fluorescence in situ hybridization. Correlations between anatomic features and chromosome 22q11 deletion were assessed. A chromosome 22q11 deletion was detected in 20 of the 50 patients (40%). Anatomic features that were significantly associated with a chromosome 22q11 deletion included a right-sided aortic arch, an abnormal aortic arch branching pattern, both abnormal sidedness and branching of the aortic arch, and the combined category of either abnormal sidedness or branching of the aortic arch. There was a trend toward the association of discontinuous pulmonary arteries with a chromosome 22q11 deletion. Interruption of the aortic arch and truncal valve morphology and function did not correlate significantly with the presence of a chromosome 22q11 deletion. In conclusion, a chromosome 22q11 deletion is common in patients with truncus arteriosus, and those with abnormal sidedness and/or branching of the aortic arch are significantly more likely to have a deletion. Clinically important anatomic variables, such as abnormalities of the truncal valve and interrupted aortic arch, were not associated with a chromosome 22q11 deletion in this series.
