Abstract

Frontonasal dysostosis (also called frontonasal "dysplasia") comprises ocular hypertelorism, median facial cleft affecting nose and/or upper lip, unilateral or bilateral cleft of the alae nasi, anterior cranium bifidum occultum, or a widow's peak. Usually it is a sporadic disorder, although a few familial cases have been reported. We describe a 2-year-old girl with anterior cranium bifidum occultum, lipoma of genu and anterior part of the corpus callosum, and hypertelorism. Her mother had a history of a nasal drip at birth caused by a defect in the cribriform plate and phenotypically, a widow's peak. This observation suggests either autosomal dominant or X-linked dominant inheritance. The family illustrates the importance of identifying mild expression of frontonasal dysostosis before genetic counseling.
