Midline facial defects with ocular colobomata

Abstract

We describe 5 children with midline facial anomalies and iris colobomata reminiscent of frontonasal "dysplasia." Two patients have, in addition, abnormalities of the eyelids and one of them probably has the rare autosomal recessive condition frontofacionasal "dysplasia." The patients may have a new syndrome of midline facial defects, iris colobomata, and mental retardation.
