EYA1 mutation in a newborn female presenting with cardiofacial syndrome.

The combination of an asymmetric crying face and heart defect has been termed cardiofacial syndrome. This "syndrome" is etiologically heterogeneous and a subset of patients have 22q111.2 deletions. We present a female with Cayler's cardiofacial syndrome phenotype who had a frameshift mutation of the EYA1 gene. We conclude that EYA1 mutation represents a previously undescribed cause of cardiofacial syndrome.
