Hypohidrotic Ectodermal Dysplasia with Mitral Valve Prolapse.

Clinical and investigational features of a case of congenital hypohidrotic ectodermal dysplasia in a young boy are described. In addition, he was found to have mitral valve prolapse, which was confirmed by echocardiography. The available literature is discussed. Such an association, though probably fortuitous has not been previously reported.
