Oculocerebrocutaneous (Delleman) syndrome: a pleiotropic disorder affecting ectodermal tissues with unilateral predominance

Abstract

We present a patient with oculocerebrocutaneous syndrome. The boy shows only mild psychomotor delay in spite of rather severe appearing anomalies of the central nervous system. A primarily unilateral involvement of this syndrome is emphasized. A postzygotic/somatic mutation resulting in a mosaic state might account for the primarily ectodermal involvement, the unilateral predominance, and the sporadic nature of this syndrome. An alternative hypothesis of an environmental factor might also explain the clinical manifestations of the syndrome.
