Phenotypic variability in the Baller-Gerold syndrome: report of a mildly affected patient and review of the literature.

We report a patient with a mild form of the Baller-Gerold syndrome (craniosynostosis-radial aplasia syndrome). The patient, a 3-year 3 month-old boy, has trigonocephaly with bilateral absent radii and thumbs. His growth parameters and psychomotor development have been normal. No visceral anomalies were found. This patient represents a new case of the rare mild form of the syndrome.
