General Discussion

Oculocerebrocutaneous (OCC) syndrome, a rare genetic disorder, is apparent at birth (congenital). The disorder is characterized primarily by eye (ocular), brain (e.g., cerebral), and skin (cutaneous) malformations. For example, many affected infants have semisolid or fluid-filled swellings (cysts) within the cavities of the skull (orbits) that accommodate the eyeballs and associated structures. In most cases, the eye on the affected side or sides is also abnormally small (microphthalmos). Brain abnormalities associated with OCC syndrome may include malformations of the ventricular system in the middle of the brain, multiple fluid-filled spaces within the outer region of the cerebral hemispheres (cerebral cortex), and absence of the band of nerve fibers that joins the brain's hemispheres (agenesis of the corpus callosum). Affected infants and children may also have mental retardation and episodes of uncontrolled electrical activity in the brain (seizures). In addition, OCC syndrome is characterized by underdevelopment or absence of skin in certain localized regions (focal dermal hypoplasia or aplasia) and most have protruding, flesh-colored or brownish outgrowths of skin (cutaneous tags) within certain facial areas, including around the eyelids, on the cheeks, or near the ears. In all individuals with OCC syndrome, the disorder appears to occur randomly for unknown reasons (isolated, with no family history of similar disorders).
