title: Patent ductus arteriosus and microdeletion 22q11 in a patient with Klinefelter syndrome.
abstract: We describe an uncommon association of deletion 22q11 in a patient with Klinefelter syndrome. Even though congenital heart defects (CHD) are not associated with Klinefelter syndrome, further investigation of this patient with patent ductus arteriosus showed a microdeletion of chromosome 22q11.2. While this finding may be coincidental, it is important to further evaluate patients when the clinical features are suggestive of a secondary abnormality.
