Novel TFAP2A mutation in a Japanese family with Branchio-oculo-facial syndrome

Abstract

Branchio-oculo-facial syndrome (BOFS) is a rare autosomal dominant disorder characterized by craniofacial, ocular, and ectodermal anomalies. BOFS is caused by mutation of the transcription factor AP2-alpha gene (<i>TFAP2A</i>). We performed detailed genetic analysis of a Japanese family with clinically suspected BOFS and identified a novel missense mutation resulting in a predicted amino-acid substitution in the highly conserved basic DNA-binding domain of <i>TFAP2A</i> (NM_003220.2:c.699A>C).
