Cerebro-facio-thoracic dysplasia: Expanding the phenotype

We report a further two patients with cerebro-facio-thoracic dysplasia, a rare autosomal recessive condition with thoracic costovertebral dysplasia, developmental delay and characteristic facial features. One of our patients has the additional features of large, bilateral colobomas of the optic nerve, ptosis, small conical teeth and severe left-sided talipes. He also has hypermobile joints, especially in his hands and anterior subluxation of the shoulders. The second patient has hypodensity of the grey matter on magnetic resonance imaging, which is the second report of this finding in cerebro-facio-thoracic dysplasia. In addition, he has hypoplasia of the corpus callosum. These cases illustrate the expanding phenotype of this condition, and support the hypothesis that this is an autosomal recessive condition. © 2007 Lippincott Williams & Wilkins, Inc.
