Ectodermal dysplasia, primary hypothyroidism, and agenesis of the corpus callosum: variable expression of a single syndrome?
We present two unrelated children, a male and a female, with signs of ectodermal dysplasia, mental retardation, agenesis/ dysgenesis of the corpus callosum, and primary hypothyroidism. Reports of ectodermal dysplasia with CNS malformations or hypothyroidism or both are rare. We suggest that the condition we describe is a distinct entity within the large group of ectodermal dysplasia syndromes and that it has a variable clinical spectrum. As both males and females are affected and in a few reports some parents show minimal signs, the inheritance is likely to be autosomal dominant.
