Craniofrontonasal Syndrome: Atrial Septal Defect With a Novel EFNB1 Gene Mutation.

ABSTRACT

Craniofrontonasal syndrome (CFNS; OMIM # 304110) is a rare X-linked disorder with greater severity in heterozygous females than in hemizygous males. CFNS is characterized by coronal craniosynostosis, frontal bossing, severe hypertelorism, craniofacial asymmetry, downslant palpebral fissure, broad nasal root, bifid nasal tip, grooved fingernails, curly wiry hair, and abnormalities of the thoracic skeleton. There are very few cases describing association of CFNS with heart defects. We discuss a very rare feature atrial septal defect in a molecularly confirmed case of CFNS.
